They must not blindly Five Mistakes disassembly engine maintenance - Maintenance - Automotive repair and maintenance industry

People in the car use Service There are some false belief, false belief that these low level in automotive repair backward, the lack of testing means the formation of an era of long-term. The false belief sometimes seems correct, in fact not the case, great harm will be loss of vehicles, personal security is threatened, but more may be buried this accident hazards, or result in decreased vehicle performance, Wear and tear Accelerated life shortened.

1, the blind pulled down the engine thermostat If the temperature is high due to engine

blindly remove thermostat, Coolant Only large-circulation, can not adjust the cooling intensity is difficult to keep engine temperatures in a more appropriate work, but often in the engine to work under low temperature, resulting in decreased engine power, accelerating wear and tear, Fuel consumption Increase. If the engine thermostat failure after repair or replacement, the engine temperature is still high, it should repair other parts of the cooling system can not remove thermostat.

2, engine temperature, low fear high fear Some people think that Travel High when the engine temperature is not afraid of low fear. In fact, the engine temperature is low, is also a great danger. Should be based on manual car driving under normal temperature, can guarantee the life of the engine.

3, the better the water pump fan belt tightening Belt tightening is not possible. Belt too tight to stretch or break not only shorten the life of the belt, but also because of excessive tension, resulting in generator shaft, pump shaft and bearing deformation of bending the early damage. Engine fan belt tightness should meet the technical requirements, the normal degree of belt deflection assembly suitable for the 10-15mm.

4, Engine Idle Warming With idle temperature, due to the lower speed, Engine oil Lubricating oil pump can not quickly be pressed into the surface of the lubrication, oil pressure is also low, so that the engine friction of all moving parts, or semi-friction in the dry state of the work; the fuel atomization due to bad cold, so that did not burn the fuel fleeing into crankcase, cylinder walls washed out on film, will also accelerate the wear parts. So, after a few seconds the engine starts, apply fast idle speed warming, improve engine lubrication.

5, with the torch end of baking oil Baking with a torch oil the end of winter, not only will the oil additive in chemical changes, the loss of their performance, but also makes oil cement, oil and the end of deformation, easy to fire. The best approach is based on the minimum temperature in winter oil suitable choice. In areas where conditions permit, the best vehicles parked in a holding facility in the garage.

Removal method is more advanced ultrasonic spray method and the removal of nuclear clearance technique, but used up, the simplest method is physical removal and chemical removal methods. These two methods can be used along.
