Is Your BMW Overheating In Allentown? Check The Water Pump First!

Driving an overheating BMW is the last thing a BMW owner would ever want to do, as it not only affects the performance of your high-end car but also causes irreparable engine damage. Several factors can cause your BMW to overheat while driving, and the primary one is a failing water pump.

The water pump plays a crucial role in preventing the engine from overheating by efficiently circulating coolant throughout the engine. We at Schearer’s Sales & Service, Inc. have years of experience fixing BMW overheating issues, and in this article, we will explain to BMW owners why they should check the water pump when their car is overheating.

Why Does a Malfunctioning Water Pump Cause Engine Overheating?

Several factors can cause your BMW’s engine to overheat when the water pump fails. Let us have a look at these factors:

Improper Coolant Circulation

One of the leading factors behind your overheating BMW is tied to the circulation of coolant throughout the engine and radiator of your car. When the water pump encounters issues with its bearings, impeller, or leaks, it affects the flow of coolant throughout your car.

In fact, the water pump is responsible for pushing coolant through the components in your high-end car, and when it fails to perform its function, the engine temperature starts to rise rapidly. As the coolant’s heat-dissipation mechanism is severely affected, you start experiencing overheating issues in your vehicle.

Coolant Leaks

Another major problem with the water pump in your BMW is coolant leaks. Most of the time, a failing water pump leads to coolant leaks, often due to the wearing out of the shaft seal, which prevents coolant from leaking out around the spinning shaft.

In addition, due to leaks in the water pump, the coolant level in your high-end car will be depleted rapidly. Now, with an inadequate level of coolant present in the vehicle, the heat absorption mechanism from the engine simply doesn’t work, and the buildup of excess heat leads to severe overheating issues in your BMW.

Pressure Loss in Cooling System

Most BMW owners are unaware of the critical role the water pump plays in maintaining proper cooling system pressure. In fact, whenever the water pump’s operation is affected by underlying issues, the pressure in the cooling system goes for a toss.

Now, this reduction in pressure, triggered by the water pump failure, lowers the coolant’s boiling point to zero. In fact, this is a serious situation in your vehicle: the coolant can boil and evaporate, leading to hotspots and severe engine damage.

Damaged Drive Belt

Many BMW models have the water pump driven by the timing or serpentine belt. The optimal operation of the water pump depends on the belt in your vehicle functioning efficiently. Over the years, as your BMW accumulates miles, the drive belt starts experiencing issues.

This is when the water pump fails to regulate coolant flow in your car, leading to BMW drivers experiencing engine overheating. Now, if this goes on unchecked, then it can lead to severe engine damage and breakdowns in your vehicle.

Other Factors Behind Overheating Issues

Apart from the failing water pump, which causes overheating in your BMW. Several other problems might be the culprit if the water pump in your luxury car is not functioning optimally. That is why it is essential to inspect the operation of the other components of your high-end car’s cooling system.

In fact, problems like a failing thermostat, a clogged radiator, a malfunctioning cooling fan, or coolant leaks can also cause overheating problems. You should reach out to our auto repair shop near you in Allentown, PA, to have your BMW inspected by our expert mechanics.
