Product Description
1. Aging of seals: There are many seals inside the water pump, such as shaft seals and O-rings. After long-term use, these seals will gradually age and lose sealing performance, resulting in water leakage of the water pump.
2. Damage to the water pump body: The water pump body may be damaged due to long-term use or external impact, such as the rupture of the water pump housing and the damage of the water pump bearing, resulting in water leakage of the water pump.
3. Overheating: If the engine is overheated, the coolant temperature is too high, and the water pump works in a high temperature environment, the material of the water pump may become brittle, cracked or deformed, which may lead to water leakage.
4. Corrosion: The coolant contains chemicals, which may corrode the material of the water pump for a long time, resulting in corrosion damage of the water pump shell or seal and water leakage.
5. Improper installation: improper installation of the water pump, loose fastening screws or incorrect installation of seals may lead to water leakage of the water pump.
6. Damage of water pump blades: The water pump blades are impacted and worn by the cooling liquid during the working process. If the blades are damaged or deformed, it may lead to water leakage of the water pump.
7. Design defects: The design of the pump is unreasonable or there are defects in the manufacturing process, which may lead to water leakage during the use of the pump.
To sum up, the causes of water leakage of automobile water pump mainly include aging seals, damage to pump body, overheating, corrosion, improper installation, damage to pump blades and design defects. In order to avoid the failure of engine cooling system caused by water pump leakage, it is suggested to check the condition of water pump regularly and replace the aged or damaged water pump in time to ensure the normal operation and safety of the vehicle.
