Golate car parts manufacturers say that because the oil pan of a family car is wet, most of the engine oil is stored in it. Once it is damaged, the direct result is oil leakage.
Because the oil pan thread is relatively weak, it is easy to make the drain bolt slip with a little effort. Once the thread is slipped, the bolt cannot be screwed in or loosened. The most important thing is that the sealing is poor and it is easy to leak oil. The drain bolt is screwed slipped when changing the engine oil. Such cases will happen from time to time. Maybe there will be no oil leakage at the beginning, but it may leak after a long time. The tightening torque of the drain bolt is generally about 30 Nm, so it is better to use a torque wrench when tightening to prevent excessive force from slipping the thread.
2. Beware of damage to the oil pan when the Petrol Car hits the bottom
It is also common for Chery Car to hit the chassis when driving, especially when going up and down curbs, up and down steep slopes, or when there are stones on the road but they force their way through. The oil pans of general vehicles are stamped from thin steel parts, some are cast from aluminum alloy, and some are cast iron parts. No matter what material they are made of, they are not very strong. Even with the protection of the lower guard plate of the Petrol Car engine, it is not certain that the oil pan will be fine if it hits the chassis. Therefore, if the Petrol Car obviously hits the chassis, even if it does not crack, it will eventually cause a hidden danger of failure. Don't be careless. Maybe it didn't break and leak oil at the time, but it may have cracked, and it cannot be guaranteed that it will not leak in the future. If the chassis is hit, it is better to check it again to eliminate the hidden danger.
3. Oil pan oil pump
Considering that some bottoming will not cause the oil pan to crack, but it may have caused deformation, it is also necessary to prevent damage to the oil pump at this time. The oil pump is a key Petrol Car engine component. If there is a problem, it will directly cause the oil pressure to deteriorate, affecting the normal lubrication of the Petrol Car engine.
4. Prevent the cracking of the glue of the oil pan from causing oil leakage
If the seal of the oil pan is not good, it will also leak oil. Some are just oil leakage, which is difficult to detect. If there is sludge on the oil pan, there is reason to suspect that there is oil leakage in the oil pan. If the surface where the oil pan contacts the cylinder body is uneven or the seal between the oil pan and the cylinder body is not good, or the crankshaft oil seal is damaged or hardened due to aging, it will cause oil leakage in the oil pan. It is very necessary to apply enough sealant on the joint between the oil pan and the cylinder body, and also pay attention to preventive replacement of aging oil seals.
