Now that there are more and more private car owners, we all hope that our car will be open for a long time and reduce the cost of maintenance. The relevant person reminds the owner of car care to avoid the following erroneous methods.
The tank "opens the pan" and adds water. During the hot summer months, when some drivers saw the phenomenon of “cooking†in the water tank, they feared that the temperature of the engine would rise again and they would immediately turn off the fire and add water. This practice is wrong and it is very likely that the cylinder head will crack due to sudden cold. If you meet the tank "open pot", the correct way is: immediately stop, let the engine keep idle idle to continue cooling; at the same time open the hood, increase the cooling rate. After the temperature of the cooling water is lowered, the engine is turned off. If the amount of cooling water is insufficient at this time, it should be added slowly to prevent the cylinder head from cracking due to sudden cooling.
Bolt too tight. There are many fasteners on the car that are connected with bolts and nuts, and it should be ensured that they have sufficient preload, but they cannot be tightened too tightly. If the tightening is too tight, on the one hand, the connecting member will be permanently deformed under the action of the external force; on the other hand, the bolt will be permanently deformed in tension, the pre-tightening force will be reduced, and even a sliding buckle or a broken phenomenon will occur.
