Common Signs Of BMW Water Pump Failure And Learn How To prevent it

BMW is a highly respected brand in the automotive industry but like all cars, they require care and regular maintenance. Owners of BMWs have reported that one of the most common issues that they experience is water pump failure. 

BMWs are equipped with an electric water pump and seeing that this is such an important part of your BMW's cooling system, it is important to understand the signs of a faulty pump so that you can attend to it as soon as possible to prevent further damage.

In this article brought to you by AfricaBoyz Online, we will discuss BMW electric water pump failure, the causes, common signs to look out for, and what you can do to prevent water pump failure in the first place.

Five Common Symptoms That The BMW Water Pump Failure Is Imminent:

1. Coolant Leaks

As the water pump begins to wear with age, so do the various seals and gaskets. If the coolant cannot be properly contained by these sealing methods, coolant leaks will occur when the water pump begins to fail. If you notice any liquid leaking from the front part of your car, pay attention. If the liquid is blue in color, it is quite possible that you have a coolant leak.

2. High-pitched Whining Sounds

High-pitched whining noises coming from your engine may indicate a loose belt, which could stem from a  loosened pulley or worn-out bearings in the water pump.  In order to avoid a complete water pump failure, you will need to replace the water pump if the bearings have worn out completely.

3. Engine Overheating 

Never ignore an overheating engine! There are numerous reasons for an engine to overheat and a failed water pump is one of them. When the engine’s coolant cannot flow properly through it, it will inevitably lead to overheating. If your dash is lighting up with warning signs, or the temperature gauge is in the red, have it attended to right away. A failed water pump will not only cause your car to overheat, but it can also cause additional engine damage such as cracked cylinder heads and head gaskets, for example. The longer you drive without the engine being cooled down, the more significant damage is done.

4. Steam Coming From The Radiator

If your engine is overheating and the water pump is faulty, you will more than likely notice steam coming from the radiator.  The water pump’s main function involves circulating water to the radiator so if there are any disconnects in the hoses, or if the water pump is faulty, the coolant cannot flow correctly, leaving your engine susceptible to overheating. 

This must be treated urgently and if you notice steam coming out whilst driving, pull over immediately. It is recommended to keep an extra bottle of coolant in your car at all times for emergencies such as these but it is best to have your BMW towed to your nearest mechanic or BMW specialist.

5. Higher Mileage

The age of the BMW and the mileage can play another important part in the equation.  As with all cars, things can start to go wrong as the car ages and the mileage climbs. It is normal for some of the parts to begin needing replacement more often. BMW water pumps in particular, do not have an indefinite lifespan and are subject to wear and tear. It is said that a water pump replacement would usually be needed around the 80,000-mile mark.

The water pump is made of plastic material, and over time the plastic will begin to crack and corrode. Other issues with water pumps could be caused by problems with the bearing or the impeller pieces. 

How To Prevent Water Pump Failure

Routine Maintenance

It is essential to follow your routine BMW maintenance schedule and have your water pump serviced at the recommended intervals.

Regular Coolant Changes

Fluid care is singularly one of the most critical aspects of ongoing care and maintenance in BMWs. Regular changing of the coolant and standard coolant flushes is especially important. Contaminated or old coolant can cause serious engine problems and becomes ineffective at regulating the engine’s temperature. This leads to engine overheating and can cause other problems, as well as damage to the water pump. 

Any Change In Your BMW’s Performance

If you notice something does not feel right and there is a change in your BMW’s performance, it may be worth it to have a professional look at your BMW.
