Your car’s water pump is expected to last a long time. Typically, they can last anywhere between 60,000 miles and 100,000 miles. Although, it depends on your driving habits, road conditions, environment, and how well you take care of your BMW. It is inevitable that over time, your Beemer’s water pump will need to be changed. However, you can definitely increase the longevity of the water pump by maintaining your Bimmer on a regular basis. In this article, we’ll talk about what causes water pump failure, symptoms to look out for, and what to do when the inevitable happens.
Your car’s water pump is a very important component. It is part of the cooling system and helps the engine from overheating. The pump forces coolant from the radiator into the various sections of the engine to regulate the heat. In most cars, the water pump sits in front of the engine block.
Why Does a Water Pump Fail?
There are several issues that can cause your BMW’s water pump to malfunction. Here are some typical reasons:
- Coolant Issues: If there is not enough coolant or if the coolant is tainted, sedimentation can occur in the water pump, causing blockage and even corrosion.
- Coolant Leaks: When seals and gaskets fail, coolant begins to leak. Not only does it corrode vital components around the housing, but this can also let air into the cooling system, leading to system failure.
- Worn Out Bearings: The bearings play a vital role in the pump’s ability to function correctly. Fatigued bearings can cause the water pump to seize up.
- Circulation Problems: The impeller in a water pump is a rotating disc that aids in the circulation of the coolant. If the impeller is damaged the water pump will not work.
- Low Pressure: A defective radiator pressure cap can create low pressure in the system, which will impact the water pump’s performance. Faulty seals, a clogged radiator, and leaking hoses can also create such a condition.
- Improper installation: It is obvious that incorrect installation of any component in your Bimmer can cause severe damage to the water pump and to its surrounding components. For example, an overly tightened timing belt or chain can create pressure and break the water pump.
Signs That the Water Pump in Your Car is Having Problems
Below are some symptoms that show your Beamer’s water pump might be on its way out.
- Engine is overheating.
- Visible smoke emanating from the engine block.
- Steam rising from the radiator area.
- Temperature gauge on the dashboard points to ‘H’ (hot) or fluctuates.
- Coolant leaks are evident around the engine or under the car.
- You can hear a high-pitched whining noise from the engine area of your car.
- Signs of corrosion or rust in the water pump are apparent.
- Grinding noises from the engine are heard.
- There are strange clunking sounds while driving.
- You notice broken or damaged shafts and seals.
- Sludge and deposit build-up inside the water pump is visible.
- Heater is not working.
- Check Engine Light (CIL) is illuminated.
Driving With a Defective Water Pump
One of the biggest problems with a malfunctioning water pump is that your BMW’s engine will overheat. An overheated engine can lead to a myriad of costly problems, the worst being catastrophic engine failure. If you must drive with a broken water pump, keep it to an absolute minimum, for example, to get to your mechanic. You should not drive more than just a few minutes at a time. Stop every five or so minutes, let the engine cool off, and start back again.
