Top 5 Signs Your BMW Needs a New Mechanical Water Pump 11518591718

When your BMW's 11518591718 mechanical water pump starts to fail, it can cause a host of problems. Here are five key signs that can help you determine if your mechanical water pump needs to be replaced:
1. Coolant leakage
Aging or damage to the water pump sealing ring will cause coolant to leak from the pressure relief hole or sealing surface of the water pump.
2. Engine overheating
The water temperature gauge pointer enters the red zone or the "engine overheating" warning light appears on the instrument panel.
3. Strange noises
Squeaks, squeals or grinding sounds coming from the engine compartment, especially when accelerating.
4. Coolant color change or impurities
Internal corrosion of the water pump or impeller wear will produce impurities and contaminate the coolant.
5. The water pump shaft is shaking or loose
Severe wear of the water pump shaft or bearing will cause looseness and affect the normal operation of the water pump. Long-term looseness will damage the belt or related parts.
