Speaking of car maintenance，Many car owners have their own maintenance "recipes"，Sometimes I am still happy to share my experience with my friends，But there are some "folk remedies" that are not only useless，It will also cause damage to the car。Today, the editor will share with you all the "home remedies" Seabetabout car maintenance。

Many car owners go to auto repair shops for maintenance，The master will be required to apply oil (lubricating oil in many cases) on the bolts and nuts of the wheels，To prevent bolts and nuts from rusting。But they don’t know，This practice is very dangerous! When the car leaves the factory，The bolts and nuts are tightened，This is for safety reasons。When you grease bolts and nuts，It will undoubtedly reduce the friction between them，In this way, when the car is driving (especially when the road is uneven)，Bolts and nuts will become loose due to wheel vibration，Eventually leading to serious consequences。

Just think，While driving on the highway，If the wheel suddenly flies out，This is an extremely dangerous phenomenon for yourself or the car coming from behind。

Many car owners complain that their engine temperatures are too high，So remove the thermostat，Making a large circulation of coolant，In order to "cool" the engine。This approach is also wrong，And it will also bring many sequelae to the car。First，You think the engine temperature is too high，But that may not actually be the case。The thermostat is to keep the engine at a relatively stable operating temperature，Adjust the cooling intensity of the coolant。If you don’t have it，The cooling intensity of the coolant will be maintained at seabet mya high level，The engine will work at low temperature for a long time。This will only lead to three phenomena in the end: reduction in engine power、Increased fuel consumption and severe engine wear。

Therefore，If the owner finds that his engine temperature is too high，You should go to a professional auto repair shop，Repair or replace the thermostat or other cooling system components，Instead of blindly removing the thermostat。

Some car owners may feel that the water pump fan belt is tighter，The more it can drive the work of related components，Improve work efficiency。But actually，The tighter the belt is, the better。The belt that is too tight will not only break easily，This will also lead to more severe wear and even deformation of the engine shaft and water pump shaft。In fact, the tightness of the water pump fan needs to follow the corresponding regulations，There should be no human intervention (the belt needs to be adjusted manually if it is too loose or too tight)。Generally，It is best to maintain the curvature of the belt at 10-15mm。
