Why does the water pump leak?
The leakage of water pump is caused by many factors:1, the axial movement of the bearings (axial clearance is too large, resulting in static and dynamic ring open. Leak water.2, and automotive cooling liquid is also related to, if the pH of the coolant is large, will corrode the water seal of the surface, resulting in leakage.3, and the user's use is also related, and some users do not properly maintain, add an unclean coolant, resulting in impurities in the coolant. Accumulation in the water seal surface, destroy the water seal torus, forming water leakage.
Two reasons.One is that the gap between the bearings becomes larger. Damage the water seal. One is the aging of water seal.
The sealing ring is invalid
