BMW Engine Overheating Problems and Solutions

“Engine temperature too high drive moderately.” If you have seen this light come on while driving your BMW, know that there is a problem to be fixed. Generally, this overheating issue happens when you have driven your car for more than 100,000 kilometers. In this article, we are going to read about the BMW engine overheating problems and the ways to get them fixed.

Top 4 Reasons why your BMW Engine is Overheating

Given below are some of the main reasons why your BMW overheating light may come on while you are driving your car.

Faulty Thermostat

If your car is overheating, your first move must be to check the thermostat. This component is designed to open or close when your engine reaches a certain temperature range.

Water Pump Failure

The water pump on your BMW tends to fail after about 75 thousand miles. A broken water pump will cause the coolant flow to stop causing your engine to overheat.

Damaged Radiator Fan

The function of the radiator is to help the radiator fan reduce the water temperature. A faulty fan must be replaced as soon as possible.

Coolant Issues

If there is coolant blockage or leakage, your BMW engine may overheat.

Here is How you can solve these problems

Now, let’s find out how you can fix each of these problems to make sure you don’t end up causing further damage to your vehicle.

Replace the Thermostat

On your BMW, a malfunctioning thermostat valve may cause your car to overheat. The only way out is to flush out the coolant, drain the radiator and replace the thermostat. Afterward, you will have to refill the coolant to ensure the whole system is working properly.

Replace the Water Pump

If your BMW overheats and the coolant level is not decreasing, you may have a faulty pump. An easy solution to the problem is to get the pump replaced. Again, you will have to drain the radiator, flush the coolant and then replace the pump. It’s better that you replace the thermostat just to be on the safe side.

Replace the Radiator Fan

Replacing the radiator fan is relatively easier than replacing other components that we have mentioned above. All you need to do is replace the fan and connect all of the other parts again.

Fill up the Coolant

If you notice bubbles in the radiator, you have to flush the radiator to remove air from it. But if the radiator has no coolant in it, you should check the entire system for leaks. If you detect leaks, get them fixed before topping up the radiator once again.

Long story short, if you have overheating issues with your BMW radiator, you may want to check your engine for the issues listed above. Fixing these issues will help you keep your car running in tip-top condition for years to come.
