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.

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.

Buy second-hand car need to pay attention to matters

Friends often say, want to buy a used car, but do not know how to choose, do not know what to pay attention, although used car can save a lot of money, but if you buy a lot wrong with the car, not worthwhile. Have this concern is not unexpected, can not just look at the appearance and to decision, you need to use the Auto Diagnostic Tool to check the performance of the car.

Sellers To make cars look more beautiful, will advance to the car beauty and let the car looks clean, almost like new. Care of the first impression, this car certainly will leave a deep impression. Do not know the surface of cooked glamorous car, in fact there are many problems, maybe a car accident. So in the purchase of second-hand car, do not be confused by the appearance of the car.

Buy big brands of cars, that new car prices are too high, wanted to buy a used car, but luxury cars follow-up care is very troublesome, generally small repair shop can not to repair, furthermore the price is also very expensive, as well as maintenance costs, maintenance costs, might be able to buy a nice new car. In fact, more popular models and brands are the best to take care of, where can go where maintenance, cost is also reasonable, they can even use the Launch X431 IV GX4 Master or Launch X431 Diagun III tool maintenance.

Many people buy a used car through a friend, first of all is a friend and not as embarrassed openings at bargain prices, view vehicle formalities are complete, a contract's time to take a closer look, these are designed to ensure their own interests.

Cars are not consumer goods, with more or less a long time there will be some problems, so use Autel MaxiSys MS908 or Xtool PS2 tools check the condition is necessary. Check whether the body has a collision, the chassis is damaged, the exhaust pipe is rusty, as well as the engine, gearbox, water tank is leaking, seepage. The most important is the engine, the engine is the heart of the car, so should pay special attention, in addition to see the engine's appearance is dry, exhaust pipe is sealed, but also to start the car, listen to the sound of the engine is normal.

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 over speed humps Tips

Cars over some speed humps, the normal speed through the speed humps, through OBD Diagnostic Tool detection show that it will damage to the vehicle, and ride comfort have influence, encountered deceleration zone how to through?

The effect of speed humps just as its name implies is to make the vehicle to slow down, even if the vehicle is not loose throttle or brakes, the vehicle up and down motion of the reason will be because certain rate weakened. Of course, the main role of the deceleration zone or let the driver subconsciously reduce vehicle speed by this section, the initiative allows the driver to pay attention to the road conditions ahead, generally in front of the school may be crossing or continue downhill.

1. Before experiencing the deceleration zone, the first driver's consciousness is closing the throttle and tap the brakes, and pay attention to road conditions ahead, and through the rear of the rearview mirror to observe road traffic conditions, if trailing behind the vehicles more, close the throttle to reduce speed must not to slam on the brakes. It is easy to cause behind the vehicle rear end collision, you can use Launch X431 GDS or Launch X431 IV GX4 Master tool detection of brake system.

2. For automatic transmission vehicles, as well as from the deceleration zone after a short distance, according to the vehicle damping performance and road driving conditions, the vehicle speed control at 30Km / h or less, but not too low. Although the lower rate turbulence weaker sense, but it will affect the overall rate of road traffic. Vehicle speed control to a certain speed, the rear wheels begin to spin down when the band can throttle speed.

3. For manual transmission car with a manual transmission car is relatively complicated. Before entering the deceleration zone when some began to collect the oil from the deceleration and observed the traffic situation around the vehicle, and based on the vehicle speed sequential shift into low, generally 1, 2 block can be relatively stable through the deceleration zone.

In the vehicle rate below 30Km/h or lower through the deceleration zone, according to the Autel MaxiSys MS908 or Autel Maxidiag Elite MD701 detection. To a file through the deceleration zone, light step on the clutch to do linkage and throttle idle speed, the rear wheel through deceleration zone, observe the road in front, slowly lift the clutch and lightly on the accelerator, according to the speed or engine speed a step on the clutch shift into high gear. At last, the car speeds of up to normal driving state.

How to effectively prevent the car rust oxidation

Tip 1: alert subtle small flaws
Car paint surface often corroded, in addition to the common collision, scratching, driving tires up small stones to play in the paint, make the emergence of dots of a peeling paint, a long time will produce a small rust. And these small scars because most of the small, easy to be ignored. Therefore, usually to regularly use the Auto Diagnostic Tool inspection car, bonnet and body around, once found to promptly to the professional beauty shop for processing.

Tip 2: ground investigation easy to water at humidity
Vehicles traveling on the way, passing through muddy puddles, and some gaps at the underbody and interior floors, etc. are easy to accumulate sludge, such as the owner does not promptly cleaned, which makes cars rust. Thus, for doors, trunk bottom corner of the door frame of the key hole and the wipers moving parts, etc., should always use the Launch X431 V+ Pro3 or Launch X431 IV GX4 Master tool to check, while maintaining the smooth flow of the doors and body departments drainage holes, check the car cover Humidity matter , such as carpets, floor parts to prevent rust.

Tip 3: the soft paint do seal glair
Some paint softer vehicle traveling at high speed during the sand particles hit the car body may also result in a fine relying marks. For this kind of cars, glaze to body, it can form a mesh of solid protective film, improve the surface hardness, the effect can be stay for about a year. And the coating can also achieve a similar effect. Also for the bottom of the vehicle can chassis armor or a plastic sealing, which can protect chassis acid rain, corrosion protection, the original protective layer is not easy to dry and fall off, can also prevent the driving small stones the impact of the chassis.

Tip 4: Toothpaste can be temporary anti-rust coating
To deal with ordinary toothpaste. When found a new small scars, and gently wipe the toothpaste applied circle scratches. Rain or after washing, apply it. This generally reduce scratch mark, you can simply play a role in isolation, to prevent rust, through Autel Maxidiag Elite MD701 or Autel Maxidiag Elite MD702 tools to detect no problem in the short time. Especially white paint, the effect is most obvious.

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.

Timely attention to automotive air filter maintenance

Replace "three filter" according to the use of the car, maintenance and oil quality grade circumstances, automotive air filter equivalent to the human nose, the air entering the engine to go through the first hurdle, Filter the air through the blocking effect of filter paper. When the dust of the filter paper surface of the pores, it will cause blockage, which directly affect the car's engine, unimaginable consequences occur. Because the air filter and direct contact with the outside world, so it is easy to be blocked, through Auto Diagnostic Tool check found engine will accelerate the powerless and idle instability, and other symptoms, the normal work of the air filter can avoid premature engine wear and maintain the best working condition.

The density of the atmosphere contains three different basic particle contaminants that dust, debris and soot. Open highway dust content is low, but emissions from vehicles concentrated, so that the content of carbon particles in the air is significantly higher, and therefore frequently used Launch X431 IV GX4 Master or Launch X431 Diagun III tool to check the air filter. The dust concentration in the larger areas such as construction sites, sand area, air filter inspection and replacement frequency to be higher. Also now the majority of automotive air filter is made of paper, when the damp air filter, intake blocked, weak acceleration of the vehicle becomes more serious when the water is drawn into the interior of the engine into the cylinder, since water is incompressible, seriously damaged will cause the engine internal moving parts, engine even scrapped.

Few people noticed it, but auto parts Once the problem occurs, the result is the most serious threats to travel safety, not because these small parts and components affecting the active force of the car, so regular use Autel MaxiSys Mini MS905 or Autel Maxidiag Elite MD701 tool to check car engine working conditions.

How to maintain the car automatic transmission

Now city traffic condition is getting worse, car stop-go situation has become the habit of the driver. So, portable, easy these two features automatic car has quietly become the first choice for most people. Although automatic car easy and convenient, but because of the automatic transmission system is very sophisticated, if the automatic transmission fails, we need to use a professional OBD Diagnostic Tool repair, and expensive, and therefore, the automatic transmission need to be more careful care and maintenance.

The automatic transmission oil can not only play the role of lubrication cooling, but the main thing is to transfer power between the engine and gearbox. Lubricating oil temperature is generally around 120 degrees Celsius, so demanding on the quality of the oil, and must be kept clean. First frequently used Launch X431 V Pro or Launch X431 IV GX4 Master tool to check the automatic gearbox oil level is normal. Check method of automatic transmission fluid and engine oil is not the same, need to be preheated to about 50 ℃, the gear lever again after a short stay in each block in the parking and the oil dipstick corresponding normal oil level should be between the highest and the lowest line, if not, should be added in time.

In most cases, when we replace the automatic transmission oil is to remove the screw automatic transmission oil pan to miss the old oil then add new oil, but this can only put about a small part of the new oil, and there Most of the old oil remains in the gearbox. If demolition sump oil change way, you can put 70 percent of the new oil, so as to ensure the transmission of health. Presently preferred method is dynamic oil change oil change, using a dedicated gearbox cleaning equipment, the full cycle of old oil, drained and then add new oil, so that the oil change rate of 90%.

As the vehicle traveling road is rather special, road congestion, poor air quality, is easy to cause transmission oil oxidative deterioration, according to Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tool inspection data indicate that the deterioration of the transmission oil increased wear of friction between the film and increase fuel consumption, if not to change new gearbox oil for a long time, will cause oil particles increases and block oil, blocking the plunger, and even a shift impact, so the transmission oil must be replaced periodically.

How to maintenance of automatic transmission oil filter

Filter is the key projects when we maintenance to the car, oil filter, air filter, fuel filter, the so-called "three filter" Conservation has always been a point of attention. In addition to these three common commonly used filters, there is a transmission oil filter, its maintenance methods very few people know, is very simple, just use the OBD Diagnostic Tool can be.

The conservation process in the daily inspection car, the car transmission oil filter is rarely mentioned, unless damaged, affecting the transmission operation, otherwise, its maintenance is easy to be overlooked in. Because in most cases, transmission oil filter is not like oil, air or fuel filter as easy to replace. In fact, since the automatic transmission oil, ATF filter is a device for protecting the second main assemblies, so it should be kept clean or replaced in time according to the Launch X431 V Pro or Launch X431 IV GX4 Master equipment recommended by the manufacturer.

The automatic transmission usually paper filter, felted membrane filter or oil filter to filter out the dirt. Asian carmakers like using a membrane filter; and European and American manufacturers are more inclined to paper or felt filter.

Some car manufacturers have introduced long-life or maintenance-free transmission. The transmission no dipstick device and its normal maintenance, ATF and filter replacement cycle of up to 160,000 km / h.

For the ATF filter, you can't judge the performance of the filter, unlike oil filter to be replaced follow along as oil, unlike the air filter, you can take it down and clean it, transmission oil filter can only rely on inspection and maintenance process maintenance personnel inspection tips. It also reminds us that we must have understand of basic car maintenance knowledge, or you can use the Autel MaxiSys Pro MS908P or Autel MaxiSys MS908 professional equipment to check the filter work performance.

Fuel additive use common sense

The fuel additive can make up for the quality problem of the fuel itself and the shortage of the automobile machinery manufacturing limit, through the Auto Diagnostic Tool checking data show: fuel additives remove carbon deposits have to save fuel, reduce emissions and enhance the power.

More than 2 years of the car must be use fuel additives, if not continuous use can also continuously for more than three times every a month and a half, if the interval is too long suggestions with large doses of some, truly effective removal of carbon deposition, improve fuel environment.

Fuel additives Selection Considerations
1, Understand the ingredients of the additive product, this is the main factor determine product efficacy, inferior additive products for fuel, and even has a harmful effect on the engine. Many of the additives on the market have exaggerated effect, some only have clean function, there is no help for power, truly effective additives, after use of the first tank generally have obvious feeling.

2, The product is safe and reliable, many products after use will cause acid corrosion of the engine, or metal residue, but caused great damage on the car, so choose is sure to choose non corrosive, non residual brand.

3, In the selection of the additive when it is best to use well-known brand additive. Secondly, we can pay attention to product packaging certification mark, query the security code.

4, Whether the product has a brand trademark, whether the packaging has a bar code, whether the product has the quality of the authority of the certification, if it is imported products are through the formal channels. Typically use fuel additives, after a month, using the Launch X431 V+ Pro3 or Launch X431 IV GX4 Master tool to check, engine performance can significantly improve a lot.

Paper air filter installation and maintenance guide

Through Auto Diagnostic Tool checking data found paper air filter has the following advantages:
1) Filter efficiency up to 99.5% (oil bath air filter 98%), dust transmittance of only 0.1% -0.3%;
2) structure compact, can be installed in any orientation, not by vehicle parts layout constraints;
3) when maintenance is not consume fuel , but also save a lot of cotton yarn, blankets and metal materials and other substances;
4) the quality of small, low cost.

Based on the above advantages, car engines use air filter paper core is becoming more common. The key of good paper air filter is to keep its sealing performance, prevent unfiltered air from bypass entering the engine cylinder.

Paper air filter installation and maintenance guide
1. During installation, air filter and the engine intake pipe between rubber pipe coupling or direct coupling must be tight and reliable, to prevent leakage, the filter must be installed at both ends of the rubber gasket surface; fixed wing air filter housing nuts can not be tightened too much, so as not to crush paper filter.

2. In use, the air filter to prevent rain water paper, because once a large amount of water adsorbed paper, will greatly increase the intake resistance, shorten the service life.

3. Some vehicle engine is equipped with Tornado air filter, paper filter ends of the plastic cover is shroud cast blades rotating air, Launch X431 IV GX4 Master or Launch X431 V+ Pro3 tool data showed that: 80% of the dust separated by centrifugal force and collected in collection Dust arms, to dust paper filter for inhalation of dust was 20%, the total efficiency is about 99.7%.

4. During maintenance, paper filter never use oil cleaning, otherwise the paper filter will be failure, but also easily lead to accidents. When maintenance, use only the vibration method, soft brush division (which folds down to brush) or compressed air cleaning methods remove the attachment surface of the filter paper dust, dirt. Part of the strainer, should be promptly removed the dust parts, pipes, etc. of leaves and cyclone dust. Even if every time meticulously maintained, the paper filter can not completely restore the original performance, the intake resistance will increase, therefore, generally when the paper filter is required when the 4th maintenance, it should be replaced with a new air filter. If the paper filter rupture, perforation or unglued paper and cover other issues, should be replaced immediately.

Air filter is the air enters the engine from the first hurdle, automobile engine is very precise parts, the tiny impurities will damage the engine. Therefore, in the air into the cylinder before, must first go through the fine filtration of air filter, can enter the cylinder. You can use the Autel Maxidiag Elite MD701 or Autel MaxiTPMS TS601 tool regularly to check the engine, and the air filter status is related to the engine's life.

zfak6-90 and zfs6-90 type gearbox use and maintenance guide

A, use and maintenance
zfak6-90 and zfs6-90 type gearbox is of conventional structural gearbox, and is therefore generally the same gearbox, in use, should pay attention to two issues, a car is driving is prohibited in the engine flameout neutral glide. This is due to the type used in automotive hydraulic power steering system and braking system, once the driving engine flameout, power steering immediately failure, in case of emergency prone to heavy steering caused the accident. You can use the OBD Diagnostic Tool to check the gearbox working state. The engine is stalled and the air compressor is not working, such easy to cause failure of brake failure.

On the other hand, from the gearbox working angle, the car engine flameout and gearbox put it in neutral condition of high-speed planing, as the engine flameout, gearbox a shaft stop rotation, countershaft also stops rotating and the second shaft gear all cease to spin, and the second shaft is in driving sliding car driven by high-speed rotation. Due to the gearbox all the gears are in a resting state, splash lubrication can not be generated, such a biaxial within each gear shaft hole needle roller bearing is not enough lubrication and burning loss soon.

Similarly, when the car engine failure was not working properly, the car must be hauled driving, drag distances over 100 meters, must be drive shaft and the driving axle connecting flange apart, the rope bundle of drive shaft on the beam of the automobile, drive axle and drive axle disengaged, drag speed shall not be more than 60 km / hour. Otherwise, also easy to cause biaxial needle roller bearing damage. You can use the Launch X431 IV GX4 Master or Launch X431 V Pro tool to check whether the car engine has a problem.

During the maintenance should be careful to check the level of gear oil. Transmission gear oil that is not the lack of nor Cadogan. Lack of oil caused by early wear even burning fault, oil too much prone to gearbox overheating. In a gas plug on the side of the gearbox, the oil level when the car park in a horizontal position should be in the height of the plug position. There is a drain at the bottom of the gearbox plug. New car during 2000 ~ 2500 km, the first force to maintain the new oil transmission gear oil should be replaced. Oil change the best operating mode in a hot car. Must according to the actual conditions and according to the provisions of the oil gap period.

B, gearbox oil
Gearbox lubrication using gear oil. ZF type gearbox use the international standard aplgl - 4 grade, viscosity grade sae85w / 90 indicator of gear oil. You can use the Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tool to check the gearbox lubrication working state.

The present is the most widely used vehicle hydraulic power steering system, then daily how proper use and maintenance vehicle hydraulic power steering pump do? when necessary, require the use of OBD Diagnostic Tool.

Generally, in normal use and maintenance hydraulic power steering pump, need to pay attention to the following aspects:

1. The hydraulic power steering pump when used to choose the correct type of booster oil, otherwise it will affect the power steering pump efficiency and service life. You can use the Launch X431 PAD or Launch X431 IV GX4 Master tool to check power steering pump.

2. Always check the use of booster oil, booster oil must be kept clean. Regular replacement of the booster oil, in filling booster oil must be equipped with the filter.

3. If a long time parked car when restarting, do not work immediately, at least 10 minutes should be no-load operation, booster oil and other fluids to be assisted to reach normal operating state and then driving.

4. operated vehicle steering pay attention to observe steering system is functioning properly, whether the impact or noise, booster oil passage for leakage, you can use Autel MaxiTPMS TS601 or Autel MaxiTPMS TS501 tools to check in order to detect and troubleshooting.

How to DIY maintenance car battery

Battery plays an important role in the use of car, if it can not normal work, car will not start running, while the car's power consumption in winter than in other seasons is much greater, and the battery is also afraid of low temperature, low temperature battery electrical capacitance is much lower than the normal temperature. So for battery maintenance is quite necessary. Battery life of about two years, you can also use Auto Diagnostic Tool to detect battery performance. Battery maintenance is not complicated, they can do it.

The first step, With a damp cloth to scrub the battery outside, the panel, on the stigma (ie, both positive and negative poles) of dirt, oil, white powder and so easy to cause the leakage of dirt to wipe clean, and use special grease to protect trailer coupling, to prevent corrosion.

The second step is to check the battery electrolyte leakage or deformation phenomenon. Some models are equipped with all maintenance-free battery, relevant or labels, do not disassemble the battery for this, if there is leakage, deformation of the phenomenon, it is best to go to the repair shop to solve. The battery life of about two years, should be used Launch X431 IV GX4 Master or Launch X431 V Pro tools to check the battery performance, timely replacement if necessary.

The third step, if the car park a few weeks, should be remove the batteries, stored in a warmer room, to prevent freezing damage to the rear battery self-discharge. When the ambient temperature is below minus 10 degrees, fully discharged battery will freeze, must thaw the frozen processed before charging the battery, if directly charging may cause an explosion.

So, in fact, battery maintenance is not difficult, you use the Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tools to detect, do regular maintenance on their car, extending its working life.

Summer car air conditioning maintenance tips

Summer use car, certainly can not do without air conditioning. Then the use of car air-conditioning, the owners should pay attention to what? Today we'll explore the automotive air conditioning problem, of course, also need to prepare OBD diagnostic tool.

Clean the condenser
Air-conditioning system in use for some time, the surface of the condenser will be coated with some foreign body, these foreign bodies blocking the air filter, or floating on the surface of the condenser, which will affect the cooling effect of air conditioning, air conditioning will produce odor, adverse effects on the human body . Should go to the auto repair shop for an inspection of the vehicle air conditioning system, generally they will use Launch X431 IV GX4 Master or Launch X-431 PAD tool to clean the condenser surface of the foreign body, if necessary replace the air filter, in order to maintain a good environment for air conditioning running.

Lack of refrigerant
Lack of air conditioning refrigerant is the main cause of air conditioning refrigeration effect is not good. In normal circumstances, the refrigerant is not reduced, and the main reason is the refrigerant that leaked. Therefore, when check the air conditioning system, to each line carefully check joint, found to have leaked refrigerant situation due to the timely change of relevant components. May require the repair shop at the same time add refrigerant added significantly colored dye, so that when you can easily found leak and timely treatment.

Sterilization
Air conditioning system has numerous piping, duct, these ducts in daily use due to temperature changes, moisture will produce internal hard to avoid. In addition, as the microbes in the air will be left in the air conditioning duct. It's all fueled the growth of bacteria, the bacteria will breed conditioning system odors, serious harm to the health of vehicle occupants. Therefore, regular air-conditioning system for disinfection is still necessary.

Air conditioning additives
The air conditioning compressor additives can increase the compressor, reduce noise, reduce friction, and air conditioning work together to improve the efficiency and extend the life of air conditioning effect. In the auto supply store to buy air conditioning system additive package, the owner can own maintenance on the air conditioning system, the main tool is Autel Maxidiag Elite MD701 or Autel Maxidiag Elite MD703. The main effect of conditioning additives are:

1. Can improve the cooling effect, low air temperature 2-5 ℃.
2. Reduce friction compressor and prolong life.
3. Reduce the air conditioning compressor noise.
4. The fuel savings of about 10%.

Automobile brake system five common sense

The brake system is the guarantee of a car can at any time according to the driver's intention to slow down or even stop system, brake system is very important so that you can use the OBD diagnostic tool to check to ensure that the brake system to work properly. Look for Car Brake System 5 tips:

1, ABS warning light in the instrument lights up, please as soon as possible to the 4S shop inspection and handling, to avoid affecting traffic safety and travel delays. If you have Launch X431 IV GX4 Master or Launch X431 Diagun III diagnostic tool, you can check your car's problem, no need to 4S repair shop.

2, Loosen the brake after start, heard a friction brake pads and brake discs, this is normal phenomenon.

After starting the engine, the driver will be put on the brakes to shift after operation, loosen the brake vehicles running start, after gear hangs in the brake pads and brake discs have been carried out under normal temperature conditions, but did not produce great friction, vehicle gear will produce forward or backward driving force, this time release the brake pedal, the brake pad and the brake disc will produce sound. If the brake disc at the car wash water this voice will be more obvious.

3. The parking brake cable growth after a period of time: This is normal. Handbrake cable is composed of multiple sets of wires, the force after a certain ductility, in use for some time, it will have a certain elongation than the length of new car, and will not have any impact on the parking brake .

4, Brake disc rusty: the brake disc main component is iron, the vehicle is not used for a long time, the disk surface will have some rust, but the vehicle is in motion through the work of the braking system, would eliminate rust, does not affect the normal use.

5, The brake disc after the use of fever: a normal phenomenon. Brake is by friction brake pads and brake discs to achieve, is the kinetic energy is converted into heat energy in the process, it will generate heat. Keep your hands after touching the parking brake discs, to avoid burns. If you're still worried, you can use Autel MaxiDas DS708 or Autel MaxiScan VAG405 tool checks to ensure road safety.

How to maintenance long term parked cars

Due to business reasons will be long term parked car, In the purchase of second new car and put old car park over a long period of time, this approach is very bad for the car, it is prone to accidents, you can use Auto diagnostic tool to check vehicle safety performance, ensure that no problem, you can use the car to travel.

Long term not use of car failure rate is higher than the normal use of the car. Parked car more than a week, it will shorten the life of vehicles. If the vehicle long home garage for too long, the proposed re-use, timely use of Launch X431 IV GX4 Master or Launch X431 Diagun III tool checked batteries, oil, etc.

Vehicle is in motion, the engine will charge the battery, if long-term not use, the battery is not charging, still give the anti-theft devices and other electronic equipment supply, over time there will be loss of electricity, causing the vehicle can not be normal. If the battery power loss occurs frequently, the battery life will be greatly reduced. For some of the battery storage capacity had been declining and vehicle park more than a week, are likely to lead to the vehicle can not be the ignition phenomenon.

Long-term parking the car will cause engine oil, brake fluid, antifreeze and other deterioration. Seal will be relatively easy to aging, because the vehicle to stop at the contact force is always uneven seal around until the seal permanent deformation, so very easy to spill. If the tire pressure is too low or the park, such as a bad environment, but also lead to corrosion or rim tire deformation. So, after long-term parking, it is recommended vehicle to the repair shop to check all kinds of oil, after long-term parking of vehicles, it is recommended to shorten the maintenance cycle, check should also include a variety of circuits, wires, etc. beware of rats and other biting. Electronic component failure. Electronic components and connectors on the car have a common characteristic, is to water, moisture and corrosion, otherwise it will lead to failure. For suspended vehicle electronic components or plug wire connector, it will greatly increase the likelihood of damp, and suspended longer, the probability of failure is higher.

Long term parking, tire deformation. The car stopped, the weight of the car is composed of 4 parts of the tire contact with the ground contact pressure bearing, resulting in shrinkage deformation. The longer the time cars off the road, the more difficult parts of the deformation recovery, so that the weight of the tire around the distribution changes, uneven rolling radius, causing tire imbalance. Once the car into the high-speed, the body will occur chattering can be accelerated wear of tires, but also bring the problem of traffic safety. So when re-use of the car, you need to use Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 diagnostic tool to detect and avoid accidents.
