Speaking of car maintenance，Many car owners have their own maintenance "recipes"，Sometimes I am still happy to share my experience with friends，But there are some "folk recipes" not only useless，It will also cause damage to the car。Today, I will take a closer look at those "recipes" of car maintenance。

Many car owners go to auto repair shops for maintenance，All will seabet iorequire the master to apply oil on the bolt and nuts of the wheels (in many cases it is lubricating oil)，To achieve the effect of preventing rust from the bolt nut。However, they don’t know，This approach is very dangerous! When the car leaves the factory，bolts and nuts are tightened，This is for the sake of safety。When you apply lubricating oil on the bolt and nut，It will undoubtedly reduce the friction between them，So when the car is driving (especially when the road is uneven)，bolts and nuts will be loosened due to wheel vibration，Eventually leading to serious consequences。

Think about it，When driving on a high speed，If the wheels suddenly fly out，It is a very dangerous phenomenon to come to yourself or rear.。

Many car owners complain that their engine temperature is too high，So remove itTemperesental，Let the coolant be in large cycle，To make the engine "cold" down。This approach is also wrong，and will bring many sequelae to the car。First，Do you think the engine temperature is too high，But it may not actually be the case。The thermostat is to keep the engine in a relatively stable working temperature，Adjust the cooling strength of the coolant。If there is no one，The cooling strength of the coolant will be maintained at a high level，The engine will work in a low temperature state for a long time。seabet appThis will only cause three phenomena in the end: the engine power decreases、Increased fuel consumption and severe engine wear。

So，If the owner finds that his engine temperature is too high，It should go to a professional auto repair store，Maintenance or replacement of the parts of the temperature -saving or other cooling system，instead of blindly dismantling the temperature device。

Some car owners may feel that the more tightened the pump fan belt，The more you can drive the work of related components，Improve work efficiency。But actually，The belt is not the tighter the better。The belt is too tight and will not only break easily，It will also cause the engine shaft and pump axis to receive more serious wear or even deformation。In fact，Do not intervene in artificial intervention (the belt is too loose or too tight, you need to adjust manually)。Under normal circumstances，The windingness of the belt is maintained at 10-15mm is the best。
