Do you know how to the scientific use of fuel additives

How to use the fuel additive to work better? Many intend to use additives owners are still hesitant, because we are not consistent with the view of additives, additives to buy more trouble. There is another kind of circumstance, a lot of people who have buy good fuel additive products but do not know how to use, also do not know how to use the OBD Diagnostic Tool check, that will also affect the fuel additive role play. Here we ask the repair shop of professional technicians explain to us the proper use of fuel additives.

For a long time the car must use, if don't want to continuous use can also between a month with more than three times, if intervals recommended dose it slightly larger, truly effective removal of carbon deposition, improve the fuel environment. The use of the most economical method is used for the first time the way plus three times in a row, that is a new car in the first three tank, every time, in accordance with the purchase of the directions specify the percentage of adding additives. After three times, run about 3000 km to 3000 km (is different according to different road conditions and oil), again plus three times in a row, repeat this cycle is more appropriate, you can use a Launch X431 V Pro or Launch X431 Diagun III tools to check the performance of the car, you can see the obvious transformation.

For used cars, during the initial period, the additive will engine oil system in the gum or sediment washing down, it will lead to clogged filters and oil hole, this time to deal with the oil system, a cleaning and maintenance, and then follow the new car Add mode to continue to use, so purifying effect is more ideal.

Adding proportion is 1: 1000, 50ml bottles of additives can be with 50 liters of fuel; in addition, add should as the condition, models and and vehicle vehicle condition is good for the first time for about 3 bottles; condition decreased, underpowered vehicles need continuous use more than 5 bottles until the condition improved. Then choose the next box to add one or 1000 kilometers every time to add. If the engine is in good condition, it can be used to reduce the proportion of the mixture.

To remind you, as the market chaos, consumers should choose a well-known brand certified, select Do not freeloaders, should pay attention to product quality, the company strength, service assurance and brand reputation, should choose to clean the engine and hydraulic system and other conservation tools Comprehensive features well-known brands. We recommend car stick with fuel additives, keeping nozzle without clogging, no coke combustion exhaust standards; with higher mileage cars, to select super-concentrated high-quality products, and gradually clean the oil and the engine, to clean, lubricate, by Horsepower easy start effect, you can also use Autel MaxiDas DS708 or Xtool PS2 tool to check car, you will reconsider whether or not to use fuel additives.

Modified spark plug to improve vehicle power

Improve the car power is great for the performance of the car, for the use of better fuel, oil and other oil additives, plus all kinds of components, system modifications, OBD Diagnostic Tool equipment. Likewise, which takes a lot of money, which is a lot for the household expenses. How simple and economical  modification to enhance car power?

Now many people adapted to fuel-efficient as the starting point of simple modification, strive to fuel consumption in the same premise, reached in modified certain extent improve the actual effect of the dynamic performance of the vehicle. For the average power conversion has mature technology, need to use Launch X431 V Pro or Launch X431 IV GX4 Master tools. Usually around in spark plugs, wire, high flow style. In high-performance spark plugs and wire as the most affordable modification.

Common spark plug on the market there are ordinary spark plug, iridium, platinum spark plug, etc.. Ordinary spark plug electrode materials are generally made of Ni Mn alloy, iridium spark plug which belong to the rare metal iridium material. Relatively high melting point metal iridium, high temperature resistance, high pressure resistance, quality is good, so iridium spark plugs can a stronger and more stable spark.

From the price point of view, the ordinary spark plug per only 5 yuan to 10 yuan, the Japanese production of iridium spark plug every 80 yuan to 100 yuan. Generally speaking, the original factory assembly of domestic ordinary spark plug best every 20000 km to replace a, and better performance of iridium spark plugs can use the 60000 km to 8 million km, or even 10 million kilometers. So from the price performance than point of view, it is recommended that consumers buy iridium spark plugs, a small amount of money to spend, you can make the vehicle dynamic performance is more excellent, more cost-effective. Use Autel MaxiDas DS708 or XTOOL PS90 tool to replace the spark plug, the working hours for the general to tens of dollars to a hundred dollars.

Brake fluid selection and usage guide

Automotive brake fluid is what we usually say brake fluid. Brake fluid is auto transmission brake pressure in hydraulic system of a liquid medium. Brake fluid when the choose and buy, the higher the level of the brake fluid, is better. So if the quality of the brake fluid problems, what consequence can you produce? Such as brake failure, etc. But people often ignore the inspection and replacement of the brake fluid, so it is necessary to regularly use the OBD Diagnostic Tool to check the brake fluid.

When long-distance driving, the engine is in operation for a long time, or in the summer temperatures are high, these will be used to increase the temperature of the brake system. If you are using low boiling point of the brake fluid evaporation will make brake system steam pipe filled with steam, produce gas resistance, thereby blocking the brake fluid diversion pipe, it can cause brake failure phenomenon, so you need to use Launch X431 V Pro or Launch X431 Diagun III tools to check the car's performance. So the good quality of the boiling point of the brake fluid is relatively high, so the brake fluid and good abrasion resistance and liquidity and the viscosity is moderate.

As long as we open the hood, you will find there are a milky white jar, that is used to hold the brake fluid place, you can see the inside of the brake fluid, outside marked with upper and lower limits of the scale, if the liquid level in its it shows the range of the normal amount of brake fluid. If you want to add brake fluid, it is necessary to add the same level now use the same brand of the same quality brake fluid, otherwise it will layer because of different formula or produce chemical change, influence the reliability of the brake fluid, reduce the braking effect.

So you must be pay more attention to the use of the brake fluid, brake fluid generally use 1-2 years later will replace, if you don't know what time replace, you can use the Autel MaxiSys Pro MS908P or Xtool PS2 tool inspection. Brake fluid when the choose and buy, in order to avoid buy the fake and shoddy products, you'd better choose in some famous brand of brake fluid, even the after-sales service is also very perfect.

Good driving habits to prolong the service life of the battery

On the basis of the daily maintenance, but also to develop good driving habits, as follows:

1, do not frequent starting vehicles
Do not exceed 5S at the start of the engine, if the first start fails, don't rush to start again. From the working principle of the car, at this time, a continuous starting motor will certainly cause the battery over discharge and damage. So the time interval should be more than 15s. If the 3 time is still a failure, use the Auto Diagnostic Tool to find out the reasons, troubleshooting.

2, under flameout state Do not use electrical equipment inside the car for a long time
This is often encountered in the daily use of cars, but also easy to overlook the problem. For example, sit in the car to rest, et al, to fuel many drivers turn off the engine and sat in the car listening to the radio or watch DVDs, so do the purpose of fuel is reached, but deeply hurt your battery. Correct method of use is stalled in a state of continuous listening to the radio to no more than 30 min, at the same time do not recommend use equipment such as car DVD in stall condition.

3, under flameout state try not to use external power supplies
External power equipment such as dust suction machine, a portable air pump, avoid by all means not to use in vehicle flameout state. As the power of these devices is bigger, use in a stall condition for a long time can easily consume battery power, and thus affect the normal starting of the vehicle. Can be used to Launch X431 V Pro or Launch X431 IV GX4 tool test battery working condition.

4, parking must turn off the lights and the car with electrical appliances
When parking stall, forget to turn off the lights, which is a lot of new car owners easy to make mistakes. After a night of consumption of the battery, at any time may not have electricity, can not start the car. Try not to use CD, cigarette lighter and other electrical equipment in the vehicle did not start. In the course of driving, the vehicle is also less used variety of automotive electrical appliances.

5, first close the air before flameout
Most of the owners are not accustomed to air-conditioning or allow air conditioning with the vehicle starting automatically after the start, which will cause the vehicle ignition switch every time, the air conditioning system will automatically start work, the consequences are directly lead to the vehicle instantaneous power load is too high, a long time will cause a certain loss of battery. Correct habits should be, every time to reach the destination, the first switch off the A/C keys, let the wind blow for a few minutes, to ensure that the air conditioning system internal drying, reducing the breeding of bacteria. Then turn off the air conditioner before the stall. Every time after restarting a car, air conditioning.

In short, general automotive battery life in 2 years or so, if the use of Autel MaxiDas DS708 or Xtool PS2 tools to maintain proper maintenance, up to 3-4 years. We understand its function, on the basis of proper maintenance, and can develop good driving habits.

The correct way of maintenance the car handbrake

In the process of using a car parking will certainly use the handbrake. Because the driver leaves the vehicle, if not with the hand brake, then the vehicle is likely to slide and may cause an accident. Sometimes, the handbrake has pulled up, but because the brake system failure resulting in the accident. So the majority of riders should be regularly on car brake maintenance and check for proper use of Auto Diagnostic Tool. Here we introduced under the normal maintenance of the handbrake.

Handbrake lever operating position is determined
Like with the foot brake pedal, handbrake handle also has a pull stroke. Typically, when pulling the handle 70% of the entire trip, the handbrake system should be in a normal braking position, so before check braking handbrake should first find out that 70% of the working point, this work can be done through to determine the number of ratchet sound. Cars can be parked in relatively quiet place, and slowly pull the handbrake, the number of clicks while pulling ratchet issued until the end of the handle pulled up. Then calculate 70% of the total sound position, this position is the effective operating point handbrake handle, if you want to save time friend, you can use the Launch X431 PAD or Launch X431 V Pro tool detected 70 percent of the work position.

Check the handbrake mechanism Effectiveness
The car drove into a larger slope of the ramp on the road in good condition, slam the brakes, in neutral (if the automatic transmission is hanging in the N block), will work to pull the handbrake lever position just determined. Then slowly release the brake pedal, if the car does not slip occurs, it shows the effectiveness of the handbrake is good. Uphill and downhill should be done once each.

Test sensitivity handbrake
In addition to the braking efficiency, should also check the sensitivity of the handbrake, this is particularly important for the initial slope. In the absence of the slope on the road to slow down, slowly pulling handbrake handle, the handle and the sensitivity to feel joint. This method will make the handbrake mechanism wear, so check the number should not be too much. In process inspection, if found unsatisfactory handbrake brake efficiency or sensitivity can usually be by adjusting the handbrake operation cable to solve. The hand brake handle and the bottom of the cable connection (generally by the interior cover) with a tunable compensation mechanism, with wrench, loosen the lock nut, you can stretch the brake cable length. Some auto adjusting mechanism is arranged at the bottom, if inconvenient adjustment should by professional maintenance personnel to deal with, can also use Autel MaxiSys Pro MS908P or Autel MaxiScan JP701 tools to deal with.

Car battery maintenance guide

Maintenance staff said, in the car maintenance, the battery maintenance is also important. Some vehicle owners and maintenance personnel for battery maintenance do not pay attention, do not understand, did not develop good habits and cause the battery life shortened, and even damage to other electrical equipment. General battery available 2-3 years, but if you use unreasonable, 3-4 months, it may be replaced, you can check the battery through the OBD Diagnostic Tool, real-time control of battery performance.

How to determine the battery needs to be charged? Can not rely on the brightness of the headlights or sound intensity to determine the working state of the battery, you need to use the Launch X431 V+ Pro3 or Launch X431 V Pro tool to check, if the brightness of the lights dimmed, to the time when the battery has entered a state of loss, the car must not be launched. In order to ensure the normal work of the battery, the owner is best used in the battery every half an hour, start the engine to charge a battery.

Today, the car on the electric equipment more and more, such as the car after the car to use the electric power of the equipment before the headlights, tail lights, reading lights and radio or CD, so, the owner in the use of these electric equipment, as far as possible not to let the battery overload work. If flameout, no need special should first turn off the headlights, and then stall, in the night started when the car should also start the reopen after the headlight, to minimize the damage to the battery.

If you let the battery in the engine stopped state, it must prevent the battery power loss, if the loss of power is likely to cause damage to the battery. Now there is a kind of technology can repair the damaged battery, adopts pulse charging technology which will activate battery electrolyte, still can continue to use. But if losing electricity, battery will be scrapped in advance.

A 4S shop maintenance staff had said, according to use Autel MaxiDas DS708 or Xtool PS2 tool to check the battery experience, in a good car battery case, open the headlights, reading lights, radios, capacity 35Ah battery operating time is about three hours, while the capacity of 45Ah battery operating time can be a little longer, between 3-4 hours. The higher the volume of the radio or CD, the greater the power, so the battery power usage time, also consider this issue. In addition, the battery of the new and old also affect the duration of the duration of the power. If users do not install some of the original electrical appliances, such as the bass, etc., will cause the excessive use of batteries. He warned the owner, if the battery is old, working time is best not more than 2 hours.

The cause of the lubricating oil consumption too fast

Just fill the oil to the car, not a few days to check the dipstick and found that missed a lot of oil, in normal use appear this kind of problem is not normal phenomenon, called abnormal oil consumption, what are the reasons and how to deal with it? Need to use the Auto Diagnostic Tool?

The reason: the consumption of lubricating oil is divided into two kinds of normal consumption and non normal consumption. Normal consumption is because between the piston and cylinder wall as long as the movement will gap exists, regardless of gap size, there will always be a part of the oil with the up and down movement of the piston is brought into the combustion chamber with the mixture together burn. This normal consumption, the general consumption should be less than fuel consumption 1% or less. You can use the Launch X431 GDS or Launch X431 V Pro tool to check it out.

Non-normal consumption is usually because there is a fault caused by the engine itself. There are three general reasons:

First, the cylinder wall wear gap is too big, lubricating oil through the clearance between the piston and cylinder wall to burn a lot into the combustion chamber. When the tube was evident with blue smoke from the exhaust phenomenon.

Second, the oil pan and oil seals Mifengbuyan, causing oil leakage.

Third, the engine cooling bad, the engine overheated, so a lot of oil and gas generated by the crankcase ventilation tube into the inlet and the mixed gas is burned together.

Thus, if you find that the oil consumption is too fast, the engine of a system failure. To use the Autel MaxiSys MS908 or Autel MaxiDiag Pro MD801 tool to find out the reasons for repair. Of course, if you use some of the inferior oil will also appear to oil consumption too fast. So be sure to use the regular factory production of lubricating oil. In order to avoid the damage caused by engine.

BMW X1 coolant temperature warning light alarm

A driving range of about 40000 km, models E84, engine type of N46 2013 BMW X1 sport-utility vehicle, there are a lot of friends reflect the car speeding coolant temperature warning light alarm, need to use Auto Diagnostic Tool detection.

Maintenance personnel to check the expansion tank in the cooling fluid is missing, there have cooling liquid leakage traces, doubt cooling system has a leak, the system for pressurized testing, good sealing.

Detecting an engine control unit, found no fault record on coolant temperature. Use the Launch X431 GDS or Launch X431 V Pro tool control cooling fan operation, to determine the fan work normal. N46 type engine water pump is a mechanical driver, as long as the engine running it will work. So will check of the opening of the emphasis on thermostat, cooling system, circulation and cooling system on the gas resistance.

In view of the vehicle mileage is not much, so doubt any wind resistance in the cooling system, cooling fluid according to standard process of adding and steam. And adjust the liquid level to the standard position. Road test, the test member come back soon, reflect the coolant temperature is high, and connect the thermostat pipe is cold. Read the circuit diagram, see the thermostat controlled by the engine control unit. In fault diagnosis instrument to observe the thermostat signal waveform, compared with the normal car found waveform, show that no control problems. Doubt thermostat has a problem, replace the thermostat test, fault is still.

After just tried to touch his hand car radiator, we found the upper and lower temperature difference, indicating that the coolant is not flowing from the interior, replace the radiator test, fault still exists. Promote the flow of the coolant pump, use Autel MaxiSys MS908 or Autel MaxiScan JP701 tool to check the pump, the pump impeller was found not rotated. Remove the water pump turned by hand, found stuck, replace the water pump test, troubleshooting.

Car wiper and battery maintenance guide

How to identify under what circumstances need to replace the wiper?
1. From the wiper itself, the symptoms of damage. Identify whether there are cracks, cracks, rust, deformation, adhesion, color and so on; with ears to distinguish wiper when use whether jumping, such as jitter abnormal sound; the use of OBD Diagnostic Tool to check whether the hardening of the rubber, etc..

2. In the process of using see symptoms from the windshield. , look to whether have a slender stripe, is hard to see the outside world, this is because there is foreign body on the wiper or edge frayed, processing method first cleaning the edge part, if you do not eliminate symptoms will need to be replaced.

3. After the rain wiper is wiped, leaving a trail of water,  this is because the deformation of the rubber. If the rubber is not in contact with the glass surface, this suggests that the bracket deformation, wiper need replacing.

4. Check the wiper blade. The wiper pull up, finger touch on the cleaned rubber wiper blade, check whether there is damage, but also check whether the rubber blade has good elasticity, if the leaf aging, hardening crack, it should be replaced with new ones.

Check the battery electrolyte level should pay attention to what areas?
Check the electrolyte level, parked his car in a horizontal road, engine, by observing the battery shell on the scale line. Position, if it is difficult to determine the liquid surface of a battery, and with the aid of a lighting to see, can also use the Launch X431 GDS or Launch X431 V Pro tools to check the electrolyte level.

New battery is provided with an indicator, can through the indicator to check the status of the battery. Indicator on the green dots obviously show that the battery in good condition: a green dot blur, shows that lack of electricity: dots become transparent or yellow, indicate the need to replace the battery.

Its different battery indicator is displayed may be different. through Autel MaxiSys Mini MS905 or Autel MaxiScan JP701 tools real time data display, if the battery indicator is blue when normal, insufficient amount of electrolyte is red, when white needs recharging. There's battery level indicator at the square hole below the liquid level is too low, when the indicator of the level below the square hole for liquid level is too low, as it happens and square hole level as the standard, more than at the bottom of the square hole and filled with liquid mouth when too much for the amount of electrolyte.

How to maintain your car sunroof

Car sunroof is a very common configuration comfort. So the question is, did you use Auto Diagnostic Tool maintenance skylight? Here we come to the maintenance of the skylight and note to do a simple introduction.

One. Skylights use a long time, at its rails, the gap will be deposited in a lot of sand or foreign objects, such as occasional clean-up, will wear the sunroof member. It should be cleaned regularly lubricated around and avoid sand deposition, to extend the service life of the sunroof seals. Generally every six months, to use gauze or cotton dipped in water to wash the sealing tape or slide, rub after a little grease can be applied. Can be used for a fine talc, can prolong the service life of the sealing ring.

Two. Use skylights biggest concern is leaking, proper use and maintenance of skylights can effectively avoid leakage. Before entering the rainy season, in addition to clean up slide, seal gap is the foreign body, but also a harness protector or talcum powder sprayed on the seals and other components.

Three. Before turning on the skylights, should pay attention to whether the roof has obstacles to the operation of the glass panel. Sunroof panel design has isolated the heat and ultraviolet function, please use a soft cloth and cleaning agent cleaning, never sticky or have corrosive cleaning agent, you can also use Launch X431 V+ Pro3 or Launch X431 V Pro tools to detect the sunroof.

Four. On the very bumpy road best not to completely open the sunroof, otherwise may have skylights and slide rail vibration between related parts deformation caused by the too big to even make the motor damage. In addition, rain or cleaning vehicle when it is forbidden to open sunroof.

Skylight is not just a piece of glass so simple, its structure is quite complex, once skylight some failures,  using Autel MaxiSys Mini MS905 or Autel Maxidiag Elite MD701 tool maintenance and replacement costs is too high, panoramic sunroof maintenance costs even higher. Therefore, the maintenance of skylights not be ignored.

The same car, why fuel consumption high when you drive

Some car owners may very strange, the same a car, even for the same car, let others open, fuel consumption fell by half! Why do you have a higher fuel consumption than others?

1, bad habits: rapid acceleration
Personal driving habits have a relatively large impact on gasoline consumption, due to the mechanical design of a variety of styles, you need to run for a period of time will enter a relatively good state. During start-up, hard acceleration, braking and sometimes a good opportunity to reflect performance of the car. Driving this surge will make your fuel consumption, by OBD Diagnostic Tool test data show, it is 2-3 times the normal driving! Best driving speed is preferably maintained at 60-80km / h. And observe the road conditions in advance, it can be done with the throttle control for speed!

2, traffic reasons
This may not have much relationship and driving, but also fuel efficient route choices very important part, sometimes from far away, in the choice of route, try to choose not congested routes, from as short as possible! Only in this way can save more gasoline!

3, trunk mat put too much items
Vehicles carrying too heavy items, will make the fuel consumption is higher than the normal driving fuel consumption of about 2%! It may not seem like a lot, with a long time Many a little make a mickle., so many items, the count is not a small sum of money. So don't put things in the car!

4, pay attention to tire pressure
Some car owners may think that hot summer weather, the tire will Rezhanglengsu, so slightly deflating the tires! Suitable tire pressure for fuel consumption and life of tire is very meaningful! Through the Launch X431 IV GX4 Master or Launch X431 V Pro tool test, as long as there is a tire less hit 40Kpa of gas, the life of the tire is reduced by 10000 kilometers, an increase of 3%! If the tire pressure is reduced by 30%, to 40km/h to calculate the words, the fuel consumption will increase by 5%-10%! Therefore, adjust the tire pressure is more important for fuel-efficient terms!

5, engine technology
When buying a car should be aware that some young owners obsessed with appearance of the car, ignoring the fuel consumption and other factors, recommendations in the car before first practical Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tools to detect the car engine, engine technology for fuel-efficient advantage whether performance excellence. This is also very important!

Car sideslip need to timely maintenance

Rainy day driving, the vehicle sideslip possibility increases, in addition to good driving habits and skills, but also the brake and the state of the tire good is also the key to safe driving. Automobile brake system is the most dual vacuum assisted hydraulic brake. Brake fluid transfer braking force which has strong water absorption. If water into the brake fluid in the braking process, the high temperature friction will produce water vapor. The gas is compressible, the brake fluid is compressed, it will cause brake failure or even failure, so after a rainy day, the need to use the OBD Diagnostic Tool to check vehicle braking systems.

Solution: Some brake fluid absorption water more serious vehicle, in the brake fluid oil on the cover can see water droplets. So in the maintenance must use the Launch X431 PAD or Launch X431 V Pro tool to check the brake fluid, to ensure the life safety of occupants. Once found the car brake fluid suction serious, should be sent to the professional repair shop in addition to water.

Also, before the arrival of the rainy season, if the vehicle tire wear, tire wear, must be replaced. someone to reduce tire pressure every rainy season, the purpose is to make the friction between tire and ground area increases, thus increase the adhesion, actually just the opposite, it is easier to cause the tire skid, keep the normal tire pressure is very important, regular use Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tools to detect automobile tire pressure.

Car burning oil reason and solutions

The engine is the heart of the vehicle must be protected. The quality of the oil not only can reduce engine wear, increase engine efficiency, by OBD Diagnostic Tool to detect, but also to save fuel consumption, extended drain intervals and help keep the engine clean and prolong engine life, long-term performance of the engine as new.

There are three cases car burning oil
1, the valve seal leakage at the oil, because the poor quality of the valve seal, or the engine temperature is high, or exhaust vent is blocked leading to the greater impact of the valve seal.

2, Crankshaft ventilation mechanism can not be filtered out of the oil, leading to oil is sucked into the inlet, the only use Launch X431 V Pro or Launch X431 Diagun III tools to detect oil filter components, to eliminate failures or improve efficiency.

3, From piston engine oil leakage, for this performance, throttle only exhaust side have the carbon deposition, but the most damage, the main reason is lack of the inferior quality or process precision of piston and piston ring, under the turbine, the piston ring of gas oil energy is larger, the destructive force of the piston ring of piston is bigger, more heavy oil burning.

Overall, the engine burning oil to avoid is the use of qualified and suitable lubricants, and changed regularly. But note that the different cars engine design, therefore, in view of the model in different countries, the cost of repair and repair after the effect of the difference is very big. Universal significance and practical advice is to use good oil and regularly replaced.

Some burning oil was designed to be, this is actually the main part of the current owners complaints: obviously the vehicle does not have any fault, but the oil consumption is particularly large. So for the engine easy to have a fever, usually to use the Autel MaxiDiag Elite MD802 or Autel MaxiSys Mini MS905 tool to check the work condition, the regular check the oil consumption is normal, etc..

Auto cooling system maintenance tips

The most common fault of the automotive cooling system is making the car broken down, and the loss of water., With the loss of water as well as accelerating weakness fault. Checking the vehicles with the boil water tank, first you should to use the OBD Diagnostic tools to detect other related components properly, such as using the correct grade of fuel, oil, spark plugs, antifreeze and adjust ignition timing and idle air-fuel ratio. And further check the cooling system under the normal circumstances.

Daily checking for the cooling system
First look at the water tank. Under normal circumstances, the tank will keep a consistent temperature when driving, if half cold or hot situation appears, you can determine the tank internal was blocked. You can connect the tank to the two kilograms of water pressure, reverse flush, if congested, you can use small amount of cleaning agent, taking care to clean the dirt tank and observe for leaks at the same time.

Second, look at the thermostat. Some people think that the removal of the thermostat can prevent the water temperature up to high, in fact, as long as the thermostat function properly and does not cause the water temperature too high, while the engine is running at low temperatures for a long time, it will be very harmful. In addition, many additional engine thermostat is a two-way action, when the thermostat is turned off, it will force to go small circulation of cooling water, while the thermostat is turned on, small loop will be closed, the cooling water will take the big loop at a whole. If you do not install the thermostat, because of the local resistance line throttling effect, the actual flow of a cycle is with very little water, but the water temperature rises.

Finally, using the Launch X431 GDS OR Launch X431 V Pro tool to check the pump. There are three ways for the damage of the pump: leakage, turn and throw impeller corrosion. The so-called revolution is lost pump shaft and impeller with too large gap, when the engine reaches a certain speed, the pump impeller can not reach the appropriate speed, resulting in poor water circulation. Cooling fan is the main component, and some cars have been eliminated fixed fan, and replaced with silicone oil electromagnetic and fan clutch. The characteristic is it basically does not work by a cold car fan, and the maximum amount of heat hot car; silicone fan clutch main fault is that oil spills, and the main fault of electromagnetic fan clutch is damaged water temperature switch, damaged line, and the damaged electromagnetic coil.

Cooling System Maintenance
1. Use the Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tool check the cooling system seal, tightness of the fan belt, thermostat sensitivity and cooling water temperature, and keep plenty of cooling water.

Summer car maintenance 6 small common sense

In many people think maintenance is to replace the three filters, oil and other consumables. In fact, during operation of the vehicle, many parts are constantly wear, routine maintenance, inspection range well beyond the three filters, oil, brake pads, spark plugs, a lot of places if you usually do not use Auto Diagnostic Tool inspection, maintenance, maybe there will be a failure. Here is a little common sense of car maintenance in the summer.

1, air conditioning use
Open air conditioning cycle. In the summer, the temperature is often high, so that the car is just starting to open the air conditioning, it should open all the windows 3-5 minutes, until hot and then drain off the air conditioning, it would play better results. If the engine is in a large load for a long time, it should temporarily turn off air conditioning. Refrigeration and air conditioning when the wind blows up the best, because the cold air to sink, the best choice for the wind blowing side gear block, adjust the air outlet up best. Finally, noting that the former first destination off the air conditioner to reduce odor generation.

2, body care
More rain in summer and autumn, rain acid rain, as well as strong sunlight, as well as the body fell to the surface of the gum can cause corrosion and oxidation of the paint. So to make a body from cleaning, polishing to waxing, sealing the glaze and a series of beauty care is necessary. Even if your body has paint coating, it is also take care about it, wash it.

3, tire pressure
For tyres must be using Launch X431 V Pro or Launch X431 PAD tools checked, If the pattern grinding to replace the new tires. Summer tire pressure inside rises as the temperature rises, often have a flat tire accidents while driving speeding, overloading or emergency brake is easy to cause a puncture. Therefore, due to lower tire pressure, or to improve physical properties of tire helium expansion to more stable.

4, the compressor and condenser
After stopping the refrigeration system, every two weeks to make the compressor work more than 10 minutes; To check belt tension periodically compressor; if found frozen oil leakage should be timely treatment; to regularly clean the condenser, to prevent oil, dirt and debris attached to the condenser heat sink.

5, wiper blade
Because many summer rain, automobile wiper frequency of use will be very high, therefore, to strengthen the inspection of the wiper blade is particularly important. In addition to regular inspections, but also pay attention to the cleaning wiper, wiper to prevent the accumulation of dust and impurities affect the wiper effect, or an adverse effect on the windshield before the car. Once the work results of the wiper blade is not ideal, it is necessary to replace the timely repair.

6, car sterilization
It is very important to do a good job in the work of disinfection of vehicles in spring and summer. Should always open the window ventilation, regular cleaning of car exterior and interior. When you wash, you can use a disinfectant scrub, if you have time you can use the Autel MaxiSys Pro MS908P or Autel MaxiSys Mini MS905 tool testing. However, we must pay attention to the air disinfection in the car is in the car no one. Disinfection is done, the need to open the window ventilation 5 ~ 6min, the facilities in the compartment with clear water, and then clean the cotton cloth to wipe, so as to remove the residual disinfectant.

Summer car maintenance skills

Owners enjoy the car brings a variety of fun, and do not forget to do some of the necessary work, take good care of their car, regular use of Auto Diagnostic Tool to detect car, at the same time to avoid the failure of the car itself caused by traffic accidents, and put forward the following maintenance skills:

Protect the paint
Sun damage on the car paint, be sure to always wash and periodic waxing. If you want to do more thorough protection work, suggested a glaze or coating paint, paint to wear a protective clothing.

Check the brake
Under rainy wet pavement caused friction coefficient between the tire and the road surface is reduced, particularly at the tread has hydrocephalus, the lower the coefficient of friction, a sensitive braking system is particularly important, so one should always check the brake system.

Spontaneous Fire Prevention
Summer is the high incidence of spontaneous combustion vehicles, it is understood, driver's improper operation or car existence hidden danger is the main cause of car spontaneous combustion. Therefore to use the Launch X431 IV GX4 Master or Launch X431 V Pro tool check car oil electric circuit, found that aging line should be timely repairs, to prevent spontaneous combustion.

Using air conditioning
Into the car before you open the window ventilated, open the outer loop at the same time, to stay inside the heat discharge after open air conditioning, the cooling effect is better and faster. When the speed is less than 25 km/h, air conditioning should be placed in a lower gear, to prevent the occurrence of lack of electricity and air conditioning. Driving on rainy days, the window glass is fog, the influence line of sight, at this time as long as the direction of the wind will be dispatched to the windshield, open the compressor air conditioning, can be in a few seconds to achieve the purpose of effective mist.

Prevent evaporation
High summer temperatures, oil and water evaporation will increase, and therefore must take the fuel tank cap Gaiyan tubing to prevent oil leakage; always check the water level of the water tank, crankcase oil oil level, height, brake master cylinder within the brake fluid level and inside the battery electrolyte density and liquid level height, etc. Illegal, want to add and adjust in time.

Note that "freezing"
In the summer, some people think antifreeze irrelevant, can be replaced with plain tap water, in fact, this approach is wrong. Professional preparation of antifreeze is not only low temperature, high temperature characteristics are particularly good. When high-quality antifreeze approaching 200 ℃ in order to be "boiling." In addition, there are rust-proof antifreeze, cleaning effect. Therefore, the choice of the original antifreeze still summer, it can play a "sunstroke" role.

Prevent puncture
Summer surface temperature is higher, automobile tire using the environment even worse, so be sure to pay attention to doing a good job of inspection and maintenance of the automobile tire, regular use of Autel MaxiSys Pro MS908P or Autoboss V30 SPX tools to check the tire pressure, to prevent puncture.

Oil tank filled full oil has four big taboo

Many owners like to say fill full when fill oil, usually come added to jump the gun, always want to continue oil into the tank, in order to scrape together a integer. Do you know? Through Auto Diagnostic Tool check data show that gas tank is too full can damage the car, and there are serious damage, there are four points of damage:

1, easy to cause fire
If you add too full of oil, oil is easy to overflow from the tank vent. A waste of gasoline, in case of spilled gasoline encounter fire, it is easy to fire, threatening the safety of life!

2, easily cause clogging of the vent
Once the vent plug, it will generate a negative pressure within the fuel tank, causing oil to poor, even for non-oiled. Car situation appears just after the addition was complete oil beat the fire engine, or a jump a jump phenomenon at high speeds, it is possible that due to the gas tank too full due.

3, canister constitute a hazard
Into the carbon canister is a liquid rather than a gas vapor, carbon canister would constitute a hazard. The canister is to reduce vehicle fuel tank, carburetor gasoline evaporation apparatus matter emissions. Through the Launch X431 V Pro or Launch X431 Diagun III tool check normal carbon tank should be above 50000 km, but after the immersion, immediately scrapped!

4, volatile gasoline easy carcinogenic
The activated carbon canister, generally near the outer circulation air inlet, when the oil is too full, canister saturation, pressure too high and pressure relief exhaust, containing gasoline constituents of air into the compartment, uncomfortable "gasoline" always around you. Oil and gas components have been confirmed to contain benzene and other carcinogens, if every time so that the car refueling, through Autel MaxiSys MS908 or Autel MaxiDas DS708 tool checks show will increase the risk of cancer.

Automatic transmission car maintenance knowledge

Automobile automatic transmission, manual and semi-automatic transmission car, three different types of operation of motor vehicle, automatic transmission car is easiest, many opened automatic transmission cars have awareness in this regard, therefore automatic transmission car compared with those of other two kinds of car electronic devices will be more, should pay attention to in the maintenance of more, also need to use professional Auto Diagnostic Tool repair, therefore, compared with the other two cars, vehicle with an automatic transmission is more difficult to maintenance, here to introduce some automatic-shift cars maintenance knowledge.

1. Always check the automatic gearbox oil level is normal. Check method of automatic transmission fluid and engine oil is not the same, check the engine oil in the cold state, and transmission oil is needed to oil preheated to about 50 ℃, then to block a rod in each block for 2 seconds in a stop block, the oil dipstick normal oil level should be between the highest and the lowest line, such as not enough, it is timely to add the same quality oil.

2. Correct replacement of transmission oil. Presently preferred method is dynamic change oil, cleaning equipment using a dedicated gearbox, in the gearbox during operation, the old oil full circle, emissions clean, add a new gearbox oil, so oil change rate is as high as 90%, to ensure good oil effect.

3. Master replacement of automatic transmission oil cycle. Automatic transmission internal control mechanism is very precise, with a small gap, so most manufacturers recommend automatic transmission oil change is usually two years or 40,000 to 60,000 km. During normal use, the transmission fluid temperature is generally around 120 degrees Celsius, so the quality of oil in demanding, must also be kept clean, as well as regular use Launch X431 V Pro or Launch X431 V+ Pro3 tools to detect. Secondly, gearbox oil to use after a long time will produce grease, it is possible to form sludge, will increase the friction plate and the parts wear, but also the influence of hydraulic system, make the power transfer is affected. Third, the dirty oil sludge will enable each valve body moving smoothly, hydraulic control affected, so that the automatic transmission abnormal.

Automatic transmission vehicle maintenance and repair in strict accordance with the maintenance manual to repair, encountered do not understand the situation, do not go to their private to deal with, go to a specialized repair shop or 4S shops to consult professional people, but the best maintenance method is usually the correct use of the car, regular use Autel MaxiTPMS TS501 or Autel MaxiTPMS TS601 tool to check the car's overall situation.

Maintenance and inspection method of automobile shock absorber

Automotive shock absorber is used to suppress the shock of spring when the shock and the impact from the pavement. The spring can be used to filter the vibration of the pavement, but the spring itself will have a reciprocating motion, and the shock absorber is used to suppress the spring jump. Through Auto Diagnostic Tool checking, the shock absorber is too soft, the body will be jumping up and down, shock absorber is too hard will bring too much resistance, interfere with the normal work of the shock absorber. Teach you how to maintain the working effect of shock absorber and how to check it.

1, Oil seal gasket, sealing gasket rupture damage, storage cylinder cover nut loose. May be oil seal, seal gasket damage, should be replaced with new seals. If you still can not eliminate oil leakage, should pull out spring strut, if feel the card or not at that time, light and heavy, then, using the gap between Launch X431 V Pro or Launch X431 Diagun III tool to check the piston and cylinder is too large, shock absorber piston connecting rod for bending, the piston connecting rod surface and the cylinder have scratches or marks.

2, Press firmly on the bumper, then release, if the car has 2 or 3 times to jump, then the shock absorber works well.

3, when the car slowly driving and emergency braking, if the car more intense vibration, there is something wrong with the shock absorber.

4, Remove the shock absorber to its upright, and the lower end of the connecting ring folder on the vise, pull compression damping lever several times, then there should be a stable resistance, pull up resistance should be greater than pressed down resistance, such as resistance to unstable or no resistance may be internal shock absorber valve parts lacking fuel or damage should be repaired or replaced.

5, in determining the shock absorber problem or failure, should first check the shock absorber for leaks or traces of old oil spills.

6, To make the car drive 10km on the poor condition of roads on the road parking, touch the shock absorber shell, if not very hot, no resistance in the shock absorber, shock absorber does not work. At this point, can be added to the appropriate lubricating oil, and then test, if the shell fever, for the shock absorber internal lack of oil, should refuel; otherwise, the shock absorber failure.

7, if the damper does not leak phenomenon, should check the shock absorber connection pin, connecting rod, connecting hole, rubber bushings and other damage, sealing off, break or fall off place. If these were normal, should be further decomposed shock absorbers, check with the gap between the piston and cylinder is too large cylinder with or without injury, the valve seal is good, the valves and valve seat are tight fitting and Save Dilatation shock absorber spring is too soft or broken, take grinding to repair or replace parts of the approach according to the situation.

8, In addition, shock absorber in actual use will rattle the fault, which is mainly due to the shock absorber and the steel plate spring and frame or shaft of the collision, the rubber pad damage or loss and damper dust-proof cylinder deformation, caused by insufficient oil should be to identify the reasons, to be repaired.

9, shock absorbers after the inspection, repair should be in a special test stand performance test, when the resistance frequency at 100 ± 1mm, which stretch stroke and stroke compression resistance should meet the requirements, showed normal shock absorber.

I suggest that you use by bumper way to check on how the working conditions of the shock absorber. Because this approach is simple and relatively less time-consuming, but also very intuitive and accurate test results. You should regularly check the shock absorbers have no oil leakage, and if there is leakage oil will affect its work, should go to 4S shop use professional Autel MaxiSys Pro MS908P or Autel MaxiSys Mini MS905 tools for maintenance.
