Speaking of car maintenance, many car owners have their own maintenance "folk prescription", and sometimes they are happy to share their experiences with friends, but some "folk remedies" are not only useless, it will also cause damage to the car. Today, the editor will count the "folk prescription" about car maintenance with you ".
Bolt and nut oil coating anti-rust
When many car owners go to the auto repair shop for maintenance, they will ask the master to grease the bolts and nuts of the wheels (in many cases it is lubricating oil) in order to prevent the bolt and nut from rusting. However, they did not know that this practice was very dangerous! When the car leaves the factory, the bolts and nuts are tightened, which is for the sake of safety. When you apply lubricating oil to bolts and nuts, it will undoubtedly reduce the friction between them, so when the car is driving (especially when the road surface is uneven), bolts and nuts will loosen due to wheel vibration, which will eventually lead to serious consequences.
Try to think that when driving at high speed, if the wheels suddenly fly out, it is extremely dangerous to come to the car by yourself or behind.
Remove engine thermostat
Many car owners complain that their engine temperature is too high, so they remove the thermostat and make the coolant circulate to make the engine "cold. This method is also wrong, and it will bring many sequelae to the car. First of all, you think the engine temperature is too high, but in fact it may not be the case. Thermostat is to keep the engine at a relatively stable working temperature and adjust the cooling intensity of coolant. Without it, the cooling strength of the coolant will be maintained at a relatively high level, and the engine will work in a low temperature state for a long time. In the end, this will only lead to three phenomena: the decrease of engine power, the increase of fuel consumption and the serious wear of the engine.
Therefore, if the owner finds that his engine temperature is too high, he should go to a professional auto repair store to overhaul or replace the thermostat or other cooling system parts instead of blindly removing the thermostat.
The tighter the belt, the better
Some car owners may feel that the tighter the pump fan belt is, the more it can drive related parts to work and improve work efficiency. But in fact, the belt is not as tight as possible. If the belt is too tight, it will not only break easily, but also lead to more serious wear and even deformation of the engine shaft and water pump shaft. In fact, the tightness of the pump fan should be in accordance with the corresponding regulations and should not be intervened manually (if the belt is too loose or too tight, it needs to be adjusted manually). In general, it is best to maintain the winding degree of the belt at 10-15mm.
