Auto repair for automobile engine belt wear and prevent aging, are defined, in front of the definition of rare machine belt, the belt bears the primary outcome. In the proposed machine, via a belt drive of the auxiliary operation, such as shrink machine, air conditioner power steering pump, alternator etc.. If the belt is broken, perhaps there is a slip, will make the relevant auxiliaryloss function, or the function decline, and affect the normal use of the car.

Belt inspection process is quite simple. First check the belt tension, then you can use the thumb,press the 2 strong middle belt pulley. According to the pressure is about 10kg, the reductionhypothesis belt around 10mm, that is suitable for belt tension at. If pressure is too large, is that the lack of belt tension. If the belt there is almost no reduction, is that the belt tension is too large. Lack of tension, the belt is very easy be slipping. The tension is too large, easy damage of the auxiliary bearing. Therefore, should take corresponding adjustment nut or bolt loosen, thebelt tension adjustment to the best shape.

In addition, car repair must also wear belt. The old belt wear serious, so that the contact area ofthe belt and pulley dropped. Then just pressed the belt, the belt can be deeply sunk to thepulley groove. The rubber belt and a rubber belt that serious problem of aging, aging, mustpromptly change the new belt.

The automobile engine is the car brain, if the engine is bad, a car is useless. The car every dayto run in the street, a long time, may cause the engine belt wear or aging, so the owners generally over a period of time, will start to check the belt, so as to avoid unnecessary trouble.

People in the car repair and there are some false belief, these false belief is the formation of long-term low level of automobile manufacturing, repair means backward, the lack of testing means in the age of. These false belief sometimes seems right, in fact, has great harm, causes the vehicle damage, personal safety is threatened, and the greater likelihood is thus laid the hidden dangers of accidents, or cause the decrease of vehicle performance, wear speed,shorten the life etc..

1, the blind down engine thermostat

If the engine temperature is high and the blind demolition of the thermostat, coolant can proceed big circulation, can adjust the cooling intensity, it is difficult to ensure the engine working at asuitable temperature, but the engine is often in low temperature condition, resulting in reduction of engine power, speed up wear, increased fuel consumption. If the engine thermostat fails to repair or replace, the engine temperature is higher, it should be the other parts of maintenanceof the cooling system, the thermostat can not be removed.

2, if the engine temperature is high not low

Some people think that driving the engine temperature is high not low fear. In fact, the engine temperature is low is also a great harm. According to the normal temperature of the automobiledriving manual provisions, in order to ensure the service life of the engine.

3, pump and fan belt tightening the better

Belt tightening is not better. The belt is too tight will not only make the elongated or fracture,shorten the service life of the belt, but also because tension is too large, resulting in the early damage of the generator shaft, shaft bending deformation and bearing. Engine fan belt tightness should meet the technical requirements, the normal deflection when the belt assemblyis appropriate for the 10-15mm.

In 4, the engine idle temperature

With the idle temperature, due to the low speed, the oil pump can not quickly the lubricating oil into the lubricating oil pressure is low, the surface, the movement of engine parts under dry friction or semi dry friction condition; low temperature fuel due to poor atomization, the unburnedfuel into the crankcase, wash away the oil film wall on, will accelerate the wear parts. So, start the engine after a few seconds, the application of fast idle temperature, improve the lubrication condition of the engine.

5, burner for baking oil bottom

Winter burner for baking oil bottom, will not only make the additives in the oil and chemical changes, loss of the original performance, but also the oil cement, oil bottom deformation, easy to cause fire. The best approach is based on the minimum temperature in winter oil suitable for use. In some places, the best vehicle park in heat preservation facilities in the garage.

Removal method is more advanced ultrasonic spray method and the removal of nuclearclearance method, but the most used, the simplest way is the physical removal and chemical removal method. The two methods can also be combined.

After entering the winter, many owners have noticed the car maintenance, will be the timely replacement of oil, check antifreeze change etc.. But neglected to safeguard the traffic safety important part -- Brake oil.

One, what is the brake fluid brake fluid brake oil =?

Brake fluid is a liquid medium braking pressure transmission automobile hydraulic brake system, used in adopting hydraulic braking system in vehicle. Brake fluid is called brake oil or force oil, is an indispensable part of the brake braking system, and in the braking system, it is passed as a force of the media, because the liquid can not be compressed, so from the total pump output pressure through the brake fluid is passed directly to the pump.

Two, how to choose the high quality of brake fluid

1 appearance: high quality brake fluid appearance with honey like, pale yellow ordeep yellow, drops in the palm friction will be more and more hot. Inferior brake oilcontaining alcohol taste, liquid like water, and there may be some impurities and suspended matter.

2 boiling point: the boiling point of the higher the better, when the car long time running, the temperature will rise to the number of Baidu. If the boiling point of the brake fluid is not high enough, once the brake fluid brake as the temperature is more and more high, will vaporize, bubbles, causes not immediately brake, as can notguarantee driving safety.

3 freezing point: a point of the brake fluid is the most important fluidity, which is especially important in cold area. The quality of brake fluid in low temperature environment is still a sensitive and reliable. But the inferior brake fluid with high solidification point, when the temperature is decreased to a certain extent occurs solidification phenomenon, greatly reducing the braking performance.

4 corrosion: high quality brake fluid corrosion to metal and rubber is small, can prolong the life of the brake pump. But the brake fluid poor have more corrosive tometal and rubber, will cause the vehicle oil, brake turnover, resulting in serious accidents.

Three, replacement of brake fluid

The use of a certain period of time will be a timely replacement of brake fluid. In general, 1~2 km after check a brake fluid, and when 3~4 million kilometers or 2 yearsmust be a brake fluid replacement. After entering the winter, brake fluid before use itmay not meet the temperature requirements, timely check replacement.

Brake fluid replacement is best to professional 4S shop or special shop. In the replacement of brake fluid, to pay attention to the maintenance staff is first cleaned with alcohol brake system, the brake fluid can not mix different brands, to clean the brake system. When replaced by appearance, to distinguish whether the inferiorbrake fluid.

Brake for vehicles is the most important part of the brake fluid to a crucial role in it. So to timely inspection, timely replacement, in order to place the prevention of accidents.

Many people thought when complete, or did not use it for a long time in the morning, to idle the original geothermal car again after five minutes on the road, think it is good for the car, in fact not the case. According to a statistics show that DLF learned that engine parts wear parts for more than 90% of the proportion is within 3 minutes after cold start.

Hot car because the car after a long period of time of parking, engine oil flows back to the engine in the bottom of the oil sump. DLF said after so long ago in the car (e.g. overnight) to start the engine, the engine is in upper no oil lubrication. It takes about 30 seconds after launch because of the oil pump operation, the engine oil to the engine most in need of lubrication of piston connecting rod and crankshaft and other parts. But even after the engine immediately on the road, as long as you don't accelerator pedal motorcycle racing, keep running at low speed, the effect is the same operation and idle.

In addition, the engine before failed to reach operating temperature (about 90 to 110 degrees Celsius), the oil supply system cannot effectively because of the low temperature of gasoline complete gasification temperature of the liquid (believe everyone know to rise to the boiling point is vaporized). There is a "wet" are not gasification in gasoline and when the liquid is not easy to burn and start the engine. This relies on the role of the choke stopped some air into the cylinder to enhance the fuel/air mixing ratio and improve the engine speed makes the engine does not die. After reaching the normal operating temperature automatic choke will naturally due to mechanical action and return to normal state. Manual choke car be sure to remember to put the choke back, otherwise for oil/gas mixing ratio not only high waste gas, power, and incomplete combustion of gas will smoke.

About the gearbox change gear lubrication is the most easy to ignore people. Transmission gear oil and engine oil in the same place is: in cold vehicle gear oil flow to the gearbox lower half. Only when driving because of the operation will be at the bottom of the gear oil of gear, lubrication upper half. This is why most of the car in the cold car shift crude. The solution is not the original geothermal car can, right way should be running at low speed is slow.

DLF said, according to the above three original geothermal idle car is unnecessary, because the effect is limited, but also waste of petrol and time, and the engine idle speed idling, gasoline may also caused by incomplete combustion carbon deposit is more likely to damage the engine.

The right way to hot car should be 30 seconds after launch to hit the road in a minute. DLF remind but never high speed driving, at this time should be kept in a low speed engine speed is not more than 3000 ~ 3000 RPM. Generally keep 2000 turn, otherwise the engine and gearbox are intense wear, unable to recover. After being engine temperature rise to normal operating temperature, and restoring the driving method of the personal habits.

Car maintenance, the engine parts wear problem is outstanding, of which more than 80% of the reason is because the owner did not grasp the hot hot car or not caused by the car time has fast speed.
