Auto parts are the component elements and systems that make up a car. They range from the smallest fasteners to the largest body panels, from the engine to the seat springs. During the life of your vehicle, you will need to replace the tires, windshield wipers, brake pads, battery, spark plugs, and countless other auto parts.

There are some misconceptions in people's use and maintenance of automobiles. These misconceptions have long been formed in the era of low level of automobile manufacture, backwardness of repair methods, and lack of testing methods. These misconceptions sometimes seem correct, but they are not, and they are very harmful. They can cause damage to vehicles and threaten personal safety. The greater possibility is that these accidents may be hidden or the performance of vehicles may be reduced. Faster wear, shorter life, etc.
1. Blindly remove the engine thermostat If the thermostat is blindly removed due to the high engine temperature, the coolant can only perform a large cycle, and the cooling intensity cannot be adjusted. It is difficult to ensure that the engine works at a more suitable temperature, but the engine is often left in Working at low temperatures results in a drop in engine power, accelerated wear, and increased fuel consumption. If the engine temperature is still high after troubleshooting or replacing the engine thermostat, other parts of the cooling system should be inspected and the thermostat cannot be removed.
2, the engine temperature is not afraid of high fear of low Some people think that when the engine temperature is not afraid of high fear of low. In fact, when the engine temperature is low, the danger is also great. Cars should be driven according to the normal temperature specified in the vehicle's operating instructions to ensure the service life of the engine.
3. The tighter the water pump fan belt, the tighter the belt is, the better. Too tight a belt not only makes it stretch or break, shortens the service life of the belt, but also results in excessive deformation of the generator shaft, the water pump shaft, and early damage to the bearing. The tightness of the car engine fan belt should meet the technical requirements. Normally, the normal belt is equipped with a deflection of 10-15mm.
4. When the engine is heated at idle speed with idling temperature rise, due to the low speed, the oil pump can not quickly press the lubricant into various lubrication surfaces, the oil pressure is also low, so that the engine parts in the dry friction or semi-dry friction state Under the work; fuel due to poor low-temperature atomization, so that the unburned fuel into the crankcase, flush off the oil film on the cylinder wall, it will also accelerate the wear and tear of the parts. Therefore, after the engine is started for a few seconds, the application of fast idle temperature increases the engine's lubrication conditions.
5. Bake the oil with a blowtorch Bake the oil with a blowtorch in the winter. This will not only chemically change the additives in the oil, but also lose the original performance. It will also cause the oil to gel and deform the bottom of the oil and cause fire. The best practice is to use a suitable engine oil based on the lowest temperature in the local winter. Wherever possible, it is best to park the vehicle in a heated garage.
The more advanced methods of removal are ultrasonic cleaning and nuclear cleaning, but the most common and simplest methods are physical removal and chemical removal. Both methods can also be used together.
Engine can not be easily dismantled and maintained
