Common misunderstandings in automobile maintenance
1. Remove engine thermostat
If the engine is removed blindly because of the high temperature of the engine, the coolant can only circulate and the cooling intensity can not be adjusted, so it is difficult to ensure that the engine works at a more suitable temperature, but it will often make the engine work at low temperature, resulting in a decrease in engine power, accelerated wear and increased fuel consumption. If the engine thermostat is maintained or replaced and the engine temperature is still high, other parts of the cooling system should be maintained and the thermostat cannot be removed.
two。 Water pump fan belt as tight as possible
In fact, the tighter the belt, the better. Too tight belt will not only lengthen or break, but also lead to generator shaft, pump shaft deformation and early bearing damage. The tightness of the automobile engine fan belt should meet the technical requirements, and the deflection of the normal belt assembly is general.

Is 10 -.
3. Oil the bolts and nuts of car tires
When many drivers repair car tires, they think that applying some oil to the bolts and nuts on the wheels will prevent it from rusting. In fact, this practice is very wrong and will bring great hidden dangers to daily driving safety.
Because the bolts and nuts have been tightened and locked, if lubricated, it will loosen with the shaking of the car body and the tire itself, and it is easy to fall off at high speed, causing traffic accidents.
