Does a water pump with minor leakage need to be replaced?
1 Answers
It is best to replace it. Here are the detailed explanations: Introduction: Observe the dynamic and static rings of the mechanical seal. If there are severe burn marks, blackened surfaces, deep scratches, or if the sealing rubber has hardened and lost elasticity, these phenomena are caused by over-tightening during installation. If there is a thin layer of scale on the surfaces of the dynamic and static rings that can be wiped off, and the surfaces show little wear, this is due to the loss of spring elasticity, poor assembly, or axial movement of the motor. In such cases, replacement is necessary. It is best to replace the water pump, as most leaks are caused by damaged internal sealing rings. Typically, the entire pump is replaced directly, as repair shops generally do not attempt repairs, as they are more likely to fail again and leak, making replacement the better option. Causes: Axial movement of the bearing, excessive axial clearance, leading to the opening of the dynamic ring surface and causing leakage; this is also closely related to the vehicle's coolant. If the coolant's pH level is too high, it can corrode the water seal on the static ring surface, resulting in leakage. Additionally, maintenance plays a significant role. Poor maintenance, such as adding unclean coolant, can introduce impurities that accumulate on the water seal ring surface, damaging it and causing leakage.
