5 Things that Helps to Figure out BMW Water Pump Failure

The job of a water pump is to continually pass the coolant right through the complete cooling circuit. Thus, helps in regulating the flow rate of the coolant. A dreadful water pump can cause overheating of your Bimmer’s engine.

The reason for this shrill squeak from your BMW might be your loose belt. This slack belt could signify a slackened pulley or exhausted bearings in the water pump. 

If the bearings of your BMW have tattered entirely, it may happen that your water pump needs to be changed in order to prevent water pump failure.

4. Steam Emitting from the Radiator

The steam from your radiator is not at all a good sign. It might be coming from an overheated engine caused by the improper working of the water pump. The main work of the water pump is to circulate water to the radiator. 

If the pump is not functioning right or if the hoses contain many disconnects, the coolant will not go from one point to another in the engine, leaving it vulnerable to overheating.

5. Rust on the Water Pump

Corrosion and rust on the water pump might be another indication of your BMW water pump failure. This corrosion prevents the water pump from successfully moving the coolant. 

In this case, you need to get your pump replaced to ensure proper working of the vehicle. If you wish to know more about the proper working of a water pump, explore some maintenance tips by the car experts.
