1, blindly removed the engine thermostat

If the engine temperature is high and blindly remove the thermostat, the coolant can only be a large cycle, can not adjust the cooling strength, it is difficult to ensure that the engine at a more appropriate temperature, but the engine is often working in a low temperature, resulting in engine power , Wear accelerated, fuel consumption increased. If the engine after the failure or repair, the engine temperature is high, it should be checked the rest of the cooling system, can not remove the thermostat.

2, the engine temperature is not afraid of low fear of low
Some people think that when driving the engine temperature is not afraid of low fear of low. In fact, the engine temperature is low when the harm is also great. Should be in accordance with the provisions of the car manual operating under normal temperature, in order to ensure the life of the engine.

3, the more the better the pump fan belt
The closer the belt is, the better. The belt is too tight will not only make it elongated or broken, shorten the belt life, but also because of excessive tension, resulting in North Pentium v3 accessories generator shaft, pump shaft deformation and bearing early damage. The tension of the automobile engine fan belt should meet the technical requirements.

4, the engine with idle speed
With the idle speed, due to the lower speed, the hydraulic pump can not quickly lubricate the oil into the lubrication surface, the oil pressure is low, so that the engine parts in the dry friction or semi-dry friction work ; Fuel due to low temperature atomization, so that unburned fuel fleeing into the crankcase, washed off the wall of the oil film, will accelerate the wear of parts. Therefore, the engine starts a few seconds later, the application of fast idle temperature, improve the engine lubrication conditions.

5, with a torch baking oil at the end
Winter with a torch baking oil at the end, not only will make the oil additives in the chemical changes, loss of the original performance, but also make the oil cemented, oil deformation, easy to cause a fire. The best practice is to choose the appropriate oil according to the minimum temperature of the local winter.
The more advanced method of cleaning is the ultrasonic cleaning method and the spray nucleus removal method, but the most commonly used method is the physical removal method and the chemical removal method. These two methods can also be used.
