Automotive Shock Absorber maintenance of common sense

Usually the car travels 100000 kilometers to check a shock absorber, maintenance cycle between different models may be slightly different, your car will need to be replaced and maintenance, please through Auto Diagnostic Tool check.

Note: when you need to change the shock absorber is best in two at a time, there was a root before or after the shock absorber has a problem, need two to replace together before or after the shock absorber, because when you change a car balance uneven force, will cause shock absorber force is different, can appear more shock absorber problem!

1, before the purchase of goods, be sure to verify that car models, displacement and other information to ensure the correct types of accessories available. You can check your car maintenance manuals, you can use Launch X-431 PADII or Launch X-431 PAD tool to check.

2, each car has four vibration absorber, respectively is the front left, front right, rear left, right, if shock absorbers need replacement, best in two at a time, there was a root before or after the shock absorber has a problem, need two to replace together before or after the shock absorber, to avoid the car balance uneven force, causing shock absorber shock absorber problems.

3, the choice of quality products and services. Counterfeit Shock Absorber although the price is low, through the Autoboss V30 SPX or Xtool PS2 tool check, fake shock absorber of life less than half of the high quality shock absorber. During stretching due to bad seal caused oil spills, leaking oil would not achieve the damping effect, will have a serious sense of bumpy road. Moreover, in high-speed driving on the way will suddenly fail, causing the tilt, personal security will be seriously threatened.

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.

Car steering wheel jitter causes and solutions

Car steering wheel jitter, is our daily driving in the process of one of the most common vehicles problem, especially the vehicles driving to 50000 km to 70000 km between the most easy to appear this kind of phenomenon. Steering wheel jitter, body resonance will lead to not safe driving, need to use Auto Diagnostic Tool in time to check the performance of the car.

Cars driving speed at between 80-90 km, will appear steering wheel jitter, more than 90 kilometers per hour is back to normal. This happens mostly caused by the tire deformation or vehicle transmission system, must use the Launch X431 GDS or Launch X-431 PADII tools to check whether the front wheel orientation Angle and the toe-in meets the requirements, such as loss of quasi should be adjusted; Set up front axle try to turn the wheel, wheel static balance condition and examine whether the tire deformation is too large, such as deformation should be replaced.

Traveling on a flat road vehicle normal, but encountered potholes, steering wheel jitter. This is due to the car in the driving, because of the pull rod ball head wear loose or glue joint fall off, as there is a tire wear and tear become irregular, should be sent to the professional repair point inspection, replacement of damaged parts.

Vehicle at 30-40 km per hour, the body has shake feeling, like the feeling of by boat. This happens mostly because the tires when used in daily due to causes such as brush, bump or aging and other reasons caused by the deformation caused, by the replacement of tires.

At high speeds the steering wheel appeared jitter when suddenly hit the brakes. Brake too hard, often may cause brake disc, brake pads, overheating, encounter cold deformation, caused by steering wheel vibration. Usually in the replacement of brake pads, brake pads, symptoms can be resolved, in order to drive the vehicle safety, should be regularly used Xtool PS2 or Autel MaxiSys Pro MS908P tools to check the performance of the car.

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.

Car battery daily maintenance Considerations

The length of service life of the vehicle battery, on the one hand, depends on the structure and quality of the battery, on the other hand, it is closely related with the daily use of OBD Diagnostic Tool maintenance, so we should do the following:

1, note that securely installed and cleaning maintenance
First, the battery in the car on the installation to be firm and reliable, to prevent the vibration caused by the car in the driving caused by the loss of the internal electrode of the battery and the connection of the external wires. Second automobile starting batteries can bear a large current discharge time is short, but small current for a long time discharge will lead to reduce the battery life; so should often remove the dust on the battery, and posts and threads on the oxide and the liquid outlet overflow electrolyte, keep clean and dry, to prevent the battery self discharge.

2, pay attention to timely charge
When the battery voltage is insufficient and the light is dim, the starting weakness, should carry on the vehicle outside the supplementary charge promptly. Battery charge capacity can be reflected on the dashboard, you can also use the Launch X431 PAD or Launch X431 GDS tool to detect. When the ammeter pointer display when about a third, it should be promptly charged, charge more than two-thirds of the over-discharge. Overdischarge the charging current is comparatively large, is not conducive to reducing active substance. Cars traveling in cold regions, to avoid the battery is fully discharged, in order to avoid the electrolyte freezing.

3, regular inspection
a, check the battery housing for cracks and electrolyte leakage.

b, always check the battery cable is solid, all joint, must maintain good contact, prevent sparks, causing the battery to explode. For example, always check the battery in the holder fixing bolt tightening, often view the pole and wiring connector too is reliable; Do not insert metal objects on the battery to prevent short circuits; sealed plastic cracks to timely repair. Check the circuit of each part of the aging or short circuit.

c, regularly check the battery electrolyte density and liquid height, check the battery discharge level, to prevent over-discharge and early retirement.

d, to keep the battery charging circuit is normal, when the battery charge indicator does not necessarily excessive use of the correct display charging properly or not, you can use the following method: In the evening let the car idle state to keep open the car headlights, illuminated to a certain fixed position, eyes fixed on the center of the light closer look, then refuel anxious to see if the lights suddenly brighten, lighten describing a generator and charging circuit were normal, also can be directly used Autel MaxiSys Pro MS908P or XTOOL PS90 GDS tools to detect the battery state.

How to clean up automobile carburetors and fuel injectors

In the sandstorm weather, the vehicle will inevitably be covered with dust. The surface of the vehicle can be washed clean, but the car is the internal sand how to deal with it? Don't ignore the carburetor and fuel injection nozzle cleaning, the need for regular use Auto Diagnostic Tool to check car performance.

Generally the best put the car sent to the professional repair factory use Launch X431 PAD or Launch X431 IV GX4 Master tool inspection. first carburetor disintegration, the carburetor needle triangle and idle needle soaked in alcohol, mainly in order to remove carbon deposits; then carburetor cleaning agent with a special individual components, wipe clean assembled, with a wind blowing high-pressure air pump, the purpose is to detect patency carburetor, and finally installed carburetor, ignition adjustment.

To repair service station, required at the car after a sandstorm performance effect how, so service personnel according to the problem you provided, if the carburetor fuel mixture ratio is too thick, plug the oil coke, rear take the blue smoke, These faults are described piston ring wear ineffective.

For the clarity of the carburetor and fuel injection nozzle, mainly is to clean the idle valve and a filter screen, the cleaning should choose regular maintenance center, general street repair shop do not have these professional XTOOL PS90 GDS or Xtool PS2 equipment, just cleaning, simply not achieve any effect.

How to maintain the car battery in summer

Summer car battery maintenance is regularly use OBD Diagnostic Tool inspection maintenance, trailer coupling corroded battery case must be promptly treated to eliminate hidden dangers.

The heat of summer, the car in high temperature and under the hot sun, there will be a series of problems caused by high temperature and failure, often seen in the case of fire, causing casualties. Vehicle in the sun for a long time, the temperature inside the car sharply increased. It has been shown that when the outdoor temperature in 36 degrees Celsius, the car as long as two hours of exposure to the sun, the car will increase to 68 degrees Celsius temperature. It can be imagined, without the use of the Launch X431 IV GX4 Master or Launch X431 Diagun III tool to check the battery, in this environment is easy to short-circuit and spontaneous combustion.

How do the clean-up battery: lead to car battery pile head corrosion reason is battery liquid sulfuric acid. When the engine, generator will recharge the battery, the battery will produce hydrogen bubble, some acid composition will be followed by a hydrogen discharge battery, especially in charging system, such as the generator voltage is too high or charging without restraint, leads to charge excessive and so on, it will lead to a lot of sulfuric acid components into the battery on the panel to, then the two pile head will corrosion.

In addition, when the daily driving, before leaving the car, check to make sure that all lights and other electrical vehicle (such as radios, CD) has been shut down because of a long parking time will run out of battery power. Car battery to regular maintenance, carefully check the battery bolts through the vent plug, the battery will produce a large number of hydrogen, oxygen gas, once the exhaust valve failure or blockage, the pressure is too large, may cause explosion.

To avoid sparks, the pile head before the demolition of the battery, to all automotive electrical and ignition turned off, then use Autel MaxiSys MS908 or Xtool PS2 tool to check, and must remove the negative pole first, then remove the positive pole. In the back of the pile head, the positive electrode and the negative electrode. In addition, if you are not sure, it is best to consult the original operation of the factory in the process of safety precautions.

Auto Body jitter causes and solutions

Body slight jitter is the situation many owners often encountered. If the owners start the vehicle, if we find the body slightly shaking, then there is likely to mean that the vehicle under three kinds of condition:

If the driving car process, found the body there is a slight jitter or offsets, generally is a tire caused by failure. First may be tire balance condition, need the owner to do a four-wheel positioning and dynamic balance as soon as possible, if the vehicle is not running deviation do the tire dynamic balance, and then use the Auto Diagnostic Tool to check tire dynamic balance.

Another condition is more serious, may be because the steel ring caused by deformation, which requires owners to professional repair shop to check. This situation generally occurs in the use of a longer life of the vehicle body. General motors to replace the new tires, new rims must be used followed by the Launch X431 PAD or Launch X431 Creader VIII tool to check the tire balance, otherwise the weight average steering wheel is not easy to happen dithering phenomenon. Body jitter on driving comfort and manipulation of the judge will make a difference.

The third situation caused by shaft deformation imbalance, general this kind of situation in the chassis more car collision.

If there is a car body jitter, which is aimed at the vehicle equipped with manual transmission, the performance is: in the beginning and slowly lift the clutch pedal process, the vehicle has a jitter. This is due to a clutch three piece suit (flywheel, clutch plate and pressure plate) the irregular wear, in which one or a few pieces to produce deflection caused by, in the bonding process, clutch disc can not be smoothly joined, but a joint, a little and release of the engine power is just beginning to transfer, and suddenly slipped, the vehicle performance is similar jumps is feeling. Replace the damaged parts of the clutch in three pieces, and then use the Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tool to check the performance of the car.

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.

Summer high temperatures using car easy cause four big hidden trouble

Car paint accelerated aging
Solution method: Avoid direct sunlight washing the car, the car paint surface water droplets will produce convex lens principle, would lead to further aging car paint. Try to avoid parked in the parking lot of exposure, try to use car clothing and other materials to resist ultraviolet damage the car paint, try to paint the car waxing, sealing glaze, coating maintenance scheme, use Auto Diagnostic Tool testing cars, extend the life of the paint.

Heat easily puncture occurred
Many car owners should know that the tire pressure is too low actually tire burst a factor, but we know that the summer heat also lead to a cause of tire burst.

Solution method: Tire pressure is too high and too low are not safe, maintain normal manufacturer with tire pressure is beneficial to train operation safety. Standard tire pressure generally posted on the edge of the driver's door or the back of the cap.

Door seals easy to aging
Solution method: Sealing ring every other two quarters for a clean, dry with a clean damp sponge to wipe the dust on the slide rail, trench, reoccupy dry sponge mop wipe once more, to maintain the cleanness of seal ring. Can use the maintenance products such as table board wax on the depth of the door seal for maintenance, to prevent cracking. Can be used to Launch X431 PAD or Launch X431 GDS tools to measure performance.

Interior easy to aging
Solution method: One is the paste solar film. Good solar film in addition to cut off most of the ultraviolet ray, can also play a heat insulation effect; The second is when parking for car mount the sun block, this is to protect the automobile instrument desk, a good way to the front seat.

Other Considerations
Due to summer heat and sun exposure, high temperature inside the car, the owner don't put lighters, batteries, carbonated drinks in the car, prevent because of heat explosion caused by such accidents. Regularly use Autel MaxiSys Pro MS908P or Autel MaxiScan JP701 tools to detect cars. Hot summer weather, the driver pay attention to reasonable rest, after all, high temperature and muggy weather for driver is also a test, drive safely to keep in mind.

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.

Regularly check car shock absorber to ensure driving safety

Automobile shock absorber is one of the key parts of the car body, for driving safety is very important. With a period of time, be sure to use OBD Diagnostic Tool to check the shock absorber, timely repair and maintenance.

Car shock absorber if there has a leakage phenomenon, for the shock absorber is concerned, is undoubtedly a very dangerous thing. So, once the discovery of oil spills, we must make timely remedial measures. Focus of the inspection items in the oil seal, seal gasket rupture damage, storage cylinder cover, check the failure of these parts of the nut loose.

If discover leak, first tighten nut cylinder lid, but if shock absorber still leak oil, may be damage of oil seal, seal gasket failure, a new seals should be replaced. If still can't eliminate the oil spill, should pull out of the damping rod, if feel the hairpin or weight, reuse Launch X-431 PADII or Launch X431 IV GX4 tool to check whether the clearance between the piston and cylinder is too large, with or without shock absorber piston rod bending the piston connecting rod surface and the cylinder have scratches or marks.

If the damper does not leak phenomenon, should check the damper connecting pins, connecting rods, connecting hole, rubber bushings and other damage, sealing off, break or fall off place. If these were normal, should be further decomposed damper, check with the gap between the piston and cylinder is too large, cylinder with or without injury, the valve seal is good, whether the valve flap and the valve seat fitting closely, and whether the presence of shock absorber spring is too soft, or broken, grinding according to the circumstance or change a way to repair.

In addition, the shock absorber in the actual use of the sound of the failure, which is mainly due to shock absorber and leaf springs, frame or axle, rubber pad damage or fall off as well as the shock absorber tube deformation, oil shortage and other reasons, should identify the reasons, to be repaired.

Shock absorber in the inspection after repair, then use the AUTOBOSS V30 Elite or Xtool PS2 tool to check shock absorber performance, in order to ensure the maintenance effect is good, to ensure the normal use.

How to maintenance automobile suspension systems

Is the so-called suspension system, between the wheel and the vehicle body, take on the job of carrying the body and absorbing the vibration, to provide the best comfort. Under normal circumstances, the shock absorber may have a fever, if you do not explain the fever shock absorber oil spills. Car driving, each time shaking up and down, the suspension will be rattled, and when the uneven road surface noise intensified, it means suspension system malfunction, may be a shock absorber damage or shock absorber rubber sleeve damage. If you are not sure what the reason, you can use Auto Diagnostic Tool to check the car's performance.

Suspension - Shock Absorber check
Suspension system not only affect vehicle ride comfort, but also as through sex, stability and adhesion performance impact on other properties. The original is in the suspension system includes shock absorbers, springs, anti roll bars, rods and other parts. In turn, especially a sharp turn, body roll is too large, indicating that the damper, stabilizer bar, or is the guiding mechanism parts are damaged.

Brake System - Brake oil brakes
In daily use, to use Launch X-431 PAD or Launch X431 V+ Pro3 tool to check whether the vehicle brake deviation, braking performance how, and how the effect of the parking brake (handbrake) is. In the maintenance of the vehicle, the brake system must first be carried out in the brake oil inspection, such as the brake pipe is cracked, brake oil leakage, etc.. The brake pedal is also a part of the need to pay attention.

After you replace the brake pads, check whether the brake pedal return to normal, daily driving time to pay attention to prevent the mat to slide under the brake pedal, so the brakes can not be trampled to death.

Brake system plus brake fluid can not be mixed, at present, the market most cars are equipped with two braking systems: foot-controlled brake (brakes) and hand control of the parking brake (handbrake). Replace the brake fluid, must take the original brake oil finished, cannot mixed with, more can not be mixed with air inside the brake fluid. Generally speaking, the brake pads wear degree with habits have great relationship, automatic car brake pads with better than manual transmission fast, generally more than 20000 kilometers later, each time to do maintenance to use Autel MaxiSys Pro MS908P or Xtool PS2 tool to check the car brake pads. This can better protect the suspension system. If the rubber sleeve is badly damaged, it must be replaced with the shock absorber.

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.
