Car maintenance must pay attention to science, however, in car maintenance is often appear some problems, some people would have thought in car maintenance, but actually it is self defeating damaged car. Taizhou large Beijing Great Automotive Components Company Limited to remind you the following error Maintenance Act is equivalent to destroy the car.

A circle, waxing effect

A lot of people to wax vehicle habitually in a circle, this is not the right way. The correct way of wax is in a straight line, horizontal and vertical lines alternately, again by water flowing direction last, so as to achieve reduction in the car paint surface resulting from the effect of concentric rings.

Two, oil too much trouble

When engine oil bottom shell oil shortage, bearing and shaft neck and friction will because of the amount of oil less lubrication, aggravate the wear degree, even cause the burning ZWZ accident. But if too much oil engine in crank, connecting rod big end will produce violent agitation, which not only increased the power loss inside the engine, but also make the splash to the wall of oil increased, produce burning exhaust oil fault. Therefore, the engine oil sump oil should be controlled between the upper and lower oil foot line for good.

Three permanent deformation, bolt tightening

Cars with connection of the nut and the bolt fastening pieces in many, should ensure that it has enough pre tightening force, but also can not be screwed too tight, on the one hand will make connections under the action of external force to generate permanent deformation; on the other hand will make the bolts produce tensile permanent deformation, pretightening force decreased, and even cause slide buckle or broken phenomenon.

Four, the fan belt too tight bearing load

The high temperature in summer, some drivers think improve the fan belt tension, causing the fan belt is too tight, everyone know this approach is wrong. Fan belt should keep elastic appropriate, because too tight will make the bearing load is too large, the wear is intensified, power consumption is increased and the pump shaft bending, belt stretching deformation, shortened life expectancy.

Five, the new battery does not charge to shorten the life span

The first charge of the battery is called the first charge, and the first charge has a great influence on the service life of the battery. If you do not charge, that is, with the "water" direct use, the battery capacity is not high, life will be shortened; if a direct charge, it will shorten the life. Usually the initial charge of the battery is in charging after the electrolyte, with a small current charging about 1 hours to install the use of.

Six, in addition to the impact of traffic safety equipment

Private cars are the owner's mobile home, the pursuit of passenger comfort and luxury is understandable, but some owners do it yourself in the car to install a variety of equipment, this modification, if not handled properly, on vehicle performance and manipulation of the convenience and reliability often bring adverse effect, easy to leave sequelae or impact on traffic safety.

Seven, cooling water temperature is too low wear engine

Hot summer weather, some drivers in order to prevent the engine temperature is too high, a taste for the temperature of the cooling water as much as possible low; some drivers in order to achieve the purpose of cooling, simply to the thermostat removed, these practices are wrong. Automobile engine is afraid of hot and cold, if the cooling water temperature is too low, will make fuel combustion deterioration, increased fuel consumption, increased wear, increase the viscosity of the oil, engine power reduced. Test results show that when the cooling water temperature is 40~50 degrees Celsius, the engine wear increases 60%~80%, power is reduced by 25%, fuel consumption increased by 8%~10%. Therefore, the engine cooling water temperature is not the lower the better, the general should be controlled between 80~90 degrees celsius.
