What Causes the BMW Electric Water Pump to Keep Running?
1 Answers
Here are the reasons why the BMW electric water pump keeps running: 1. Causes of water pump damage: prolonged operation leading to aging components; failure to replace antifreeze for an extended period, causing corrosion of the water pump, which in turn prevents the water temperature from functioning properly; aging of the water pump seal causing leaks of water and oil, leading to pump damage. 2. Symptoms of water pump damage: weakened or non-existent cooling circulation, resulting in coolant boiling; leakage near the water pump area of the engine. Coolant leakage leaves traces of coolant color on the water pump vent holes, leading to symptoms such as high water temperature due to insufficient coolant; unusual noises from the water pump during engine operation. The noises may be caused by internal foreign objects or bearing wear.
