“Engine temperature too high, drive moderately.” If he has seen this light come on while he is driving his BMW, he knows there is a problem that needs to be fixed. Generally, this overheating problem occurs when he has driven his car for more than 100,000 kilometers. In this article, we are going to read about BMW engine overheating problems and ways to fix them.
Top 4 Reasons Your BMW Engine Overheats
Below are some of the main reasons why your BMW overheat light may come on while you are driving your car.
faulty thermostat
If your car is overheating, your first step should be to check the thermostat. This component is designed to open or close when your engine reaches a certain temperature range.
water pump failure
Your BMW’s water pump tends to fail after about 75,000 miles. A broken water pump will cause the coolant flow to stop and the engine to overheat.
Damaged radiator fan
The function of the radiator is to help the radiator fan reduce the temperature of the water. A defective fan must be replaced as soon as possible.
coolant problems
If there is a blockage or a coolant leak, your BMW engine can overheat.
Here is how you can solve these problems
Now, let’s find out how you can fix each of these issues to make sure you don’t end up causing more damage to your vehicle.
Replace thermostat
In your BMW, a malfunctioning thermostat valve can cause your car to overheat. The only way out is to flush the coolant, drain the radiator and replace the thermostat. You will then need to refill the coolant to make sure the entire system is working properly.
Replace the water pump
If your BMW overheats and the coolant level doesn’t go down, you may have a bad pump. An easy solution to the problem is to replace the pump. Again, you will need to drain the radiator, flush the coolant, then replace the pump. You’re better off replacing the thermostat just to be sure.
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 plug all the other parts back together.
fill the coolant
If you notice bubbles in the radiator, you should flush the radiator to remove the air. But if the radiator is out of coolant, you need to check the entire system for leaks. If you detect leaks, repair them before refilling the radiator.
To summarize, if you are experiencing overheating issues with your BMW radiator, you may want to have your engine checked for the issues listed above. Solving these problems will help keep your car running in top condition for years to come.
