A single small defect on one component can affect the overall operation of the vehicle. So, to help you, here are some useful tips that will help you determine the failure of your BMW water pump.
When we talk about the water pump, it is the centerpiece of the engine’s cooling system. And if it stops working, the real problem begins!
5 Things That Help Determine BMW Water Pump Failure
The function of a water pump is to continuously circulate coolant throughout the entire cooling circuit. It thus regulates the flow of the coolant. A faulty water pump can cause your Bimmer’s engine to overheat.
Therefore, you should check your vehicle’s water pump as soon as you encounter these situations.
1. Squealing and Whirring Noises
The cause of this high-pitched squealing from your BMW could be a loose belt. This loose belt could mean a loose pulley or worn bearings in the water pump.
If the bearings in your BMW are completely worn out, it might be necessary to change your water pump to avoid a water pump failure.
2. Engine Overheating
Several reasons can cause your BMW’s engine to overheat. If you notice your car’s temperature gauge is in the red or the dashboard displays warnings, you should immediately consult an automotive expert.
A faulty water pump will cause your car to overheat, leading to other engine damage. You could also face costly repairs for blown head gaskets and cracked cylinder heads if your water pump fails.
3. Coolant Leaks
If you ever notice an imminent leak coming from the front part of your BMW, you should not ignore it.
It’s possible that the leak is a sign of many problems about to occur. If the fluid color is blue, it might be a coolant leak from the water pump.
4. Steam Emitted from the Radiator
Steam coming from your radiator is not a good sign at all. It can come from engine overheating caused by a malfunctioning water pump. The main role of the water pump is to circulate water to the radiator.
If the pump is not working correctly or if the hoses have many disconnections, the coolant will not pass from one point to another in the engine, making it vulnerable to overheating.
5. Rust on the Water Pump
Corrosion and rust on the water pump can also be an indication of your BMW’s water pump failure. This corrosion prevents the water pump from moving the coolant properly.
In this case, it is necessary to have your pump replaced to ensure the proper functioning of the vehicle. If you wish to learn more about the proper functioning of a water pump, discover some maintenance tips provided by automotive experts.
