What Causes The Cracking Of The Engine Cylinder Head?

The cracking of the engine cylinder head may be caused by the following reasons:

1. Poor engine heat dissipation or long-term high-temperature operation causes the cylinder head to crack. Under high temperature conditions, the strength and toughness of metal materials will decrease. If there is a problem with the engine's cooling system, the cylinder head will be in a high-temperature state for a long time, causing cracking.

2. The engine cylinder head may also crack due to external impact or collision. During the driving of the vehicle, if an accident or collision occurs, the engine cylinder head may be impacted by external forces and crack.

3. Manufacturing defects in the engine cylinder head may also cause cracking. If there are defects in the casting process of the cylinder head, such as pores, sand holes, etc., it will reduce its strength and durability, and it is easy to crack during use.

The specific cause needs to be judged according to the actual situation. It is recommended that you send the vehicle to a professional repair station for inspection and repair.
