With Car the market is so hot that many people have bought their favorite cars. But buying a car is easy and hard to maintain. There are always many owners who complain that cars are prone to failure. At the same time, some owners have been using the wrong knowledge of vehicle use and maintenance to maintain vehicles, resulting in the car should not appear in the fault. Next, we summarize several erroneous areas for vehicle maintenance for your reference.

First: a blind disassembly of the engine's thermostat

Some owners will dismantle the thermostat blindly because of the high temperature of the engine. In this way, the coolant can only carry on the large circulation, can not adjust the cooling strength, and it is difficult to ensure that the engine works at a more suitable temperature, instead, the engine often works in the low temperature state, causing the engine power to decline and grinding. The loss accelerated and the fuel consumption increased.

correct practice: if the engine thermostat is troubleshooting or replaced, the engine temperature is still high, and other parts of the cooling system should be checked and repaired.

Second: the engine temperature is not afraid of the low

when the engine is working at low temperature, the engine power will decrease, the abrasion will be accelerated and the fuel consumption will increase.

it is recommended that the normal temperature should be maintained according to the specification of the vehicle manual to ensure the service life of the engine.

Third: the tighter the pump fan belt, the better the better

When the belt is too tight, it will not only lengthen or break, shorten the service life of the belt, but also cause the deformation and bending of the shaft and pump shaft of the generator and the early damage of the bearing because of the excessive tension.

Suggestion: the tightness of automotive engine fan belt should meet the technical requirements. When the normal belt is assembled, the deflection is 10-15mm.

Fourth: engine at idle temperature

When the engine is heated at idle speed, the oil pump can not press the lubricating oil into all the lubricating surfaces quickly because of the low speed of the engine, and the oil pressure is low, so that the engine parts work under dry friction or semi dry friction; the fuel is bad at low temperature atomization and makes the unburned fuel (mixed gas) into the crankcase and washed out of the cylinder. The oil film on the wall also accelerates the wear of the machine.

Suggestion: when the engine starts several seconds, the fast idle temperature will be used to improve the lubrication condition of the engine.

Fifth: bake oil bottom with a spray lamp

Many owners like to bake oil bottom with a lamp in winter. This will not only make chemical changes in the additives in the oil, lose the original performance, but also make the oil cementing, oil bottom deformation and easily cause the fire.

suggestion: suitable oil should be selected according to the local minimum temperature in winter. Where conditions permit, vehicles should be parked in the garage with thermal insulation facilities.
