Water Pump 11517586780 For BMW E65 E66

The service life of automobile water pump depends on many factors, including manufacturing quality, use environment, maintenance and so on. Generally speaking, the average service life of automobile water pumps is between 60,000 and 100,000 miles, which is about 5 to 8 years. However, some pumps may have problems ahead of time, while others may prolong their service life.

The situations that need to replace the automobile water pump include:

1. Water leakage: If water leakage is found in the water pump, whether it is coolant leakage from the water pump itself or around it, it indicates that the seal of the water pump may be worn or aging, and the water pump needs to be replaced.

2. Noise: The water pump has abnormal noise or abnormal sound during operation, which may be caused by bearing wear or impeller damage. It is necessary to replace the water pump to avoid further damage.

3. Bearing wear: The bearing wear of the water pump will lead to poor rotation or noise of the water pump, which will affect the normal operation of the water pump. At this time, the water pump needs to be replaced.

4. Impeller damage: If the impeller inside the water pump is damaged or corroded, it will affect the pumping effect of the water pump and cause the cooling system to fail to operate normally, so the water pump needs to be replaced.

5. Leakage phenomenon: If there is coolant leakage around the water pump, it indicates that there is a problem in the seal or interface of the water pump, and the water pump needs to be replaced to ensure the normal operation of the cooling system.

6. Engine overheating: If the automobile engine is overheated, it may be caused by the water pump not circulating the coolant normally. At this time, it is necessary to replace the water pump to avoid further damage to the engine.

Generally speaking, it is suggested to replace the water pump in time when there are problems such as water leakage, noise, bearing wear, impeller damage, leakage or engine overheating. Checking the working state of the water pump regularly and replacing it according to the service life and actual situation can ensure the normal operation of the automobile cooling system, prolong the service life of the engine and ensure the driving safety.
