As the car market hot, many people have bought their favorite car. But a car is easy, maintenance is difficult. There are always many owners tell the car is very prone to failure. At the same time, some owners have been using the wrong car use and maintenance of knowledge in maintenance of vehicles, resulting in a failure of the car should not occur. Next, we summarize several cars, according to maintenance errors, for your reference.
The first one: Remove the engine thermostat blind
Some owners will because the engine temperature is high and the blind dismantle thermostat, to do so, so that the cooling fluid can be a cycle, you can not adjust the cooling intensity, it is difficult to ensure that the engine is operated under more appropriate temperature, but often at a low temperature state of the engine at work, resulting in decreased engine power, accelerated wear and tear, fuel consumption increases.
The right approach: If, after the engine thermostat malfunction repair or replacement, the engine temperature is still high, it should overhaul other parts of the cooling system.
Second: the engine temperature is low is not afraid afraid of heights
When the engine is in a low temperature state often work, it will cause the engine power down, accelerated wear and tear, fuel consumption increases.
Recommendation: it should be based on a normal car driving temperature specified in the instructions to ensure that the engine life.
Third: the pump fan belt tight as possible
When the belt too tight will not only make it stretch or break and shorten the life of the belt, but also because the tension is too large, leading to the generator shaft, pump shaft bending deformation and bearing early damage.
Recommendation: car engine fan belt tightness should meet the technical requirements, deflection at normal belt assembly is 10-15mm appropriate.
Fourth: engine idling warming
When the engine idling warming, due to the low speed, oil pump lubricating oil can not be quickly pressed into the surface of the lubrication oil pressure too low, so that the various moving parts of the engine to work under dry or semi-dry friction state; fuel due to poor low temperature atomization, unburned fuel (mixed gas) into the crankcase, wash away the oil film on the cylinder wall, will accelerate the mechanical wear and tear.
Recommendation: a few seconds after the engine is started, the application of fast idle warming, improve engine lubrication conditions.
Fifth: with a blowtorch baking oil bottom
Many owners in the winter time, like to use a blowtorch baking oil bottom, doing so will not only make the oil additive chemical changes, lose their properties, but also so that oil cement, oil pan deformed easily cause a fire.
Recommendations: need according to the local winter minimum temperature chosen to adapt oil. In areas where conditions permit, it is best to have a vehicle parked in the garage holding facilities.
