Many things can cause your car to overheat but there are some obvious things to look for first:
- Low levels of antifreeze or coolant.
- Leaking cooling system – hoses leaking coolant.
- Failed cooling fan.
- Broken fan belt.
- Stuck thermostat.
- Clogged radiator.
- Failing water pump.
- Broken temperature gauge or sensor.
Subsequently, question is, how do you know if your BMW is overheating? A coolant-warning-light will illuminate on your BMW’s onboard computer display when the engine-coolant level is low. If the engine is not receiving enough coolant, it will overheat. If the coolant-warning-light is illuminated in your instrument panel, your engine is likely going to overheat soon.
Keeping this in consideration, how do you fix a overheating BMW?
If your engine is overheating, do the following to cool it down:
- Turn off the air conditioner. Running the A/C puts a heavy load on your engine.
- Turn on the heater. This blows some excess heat from the engine into the car.
- Put your car in neutral or park and then rev the engine.
- Pull over and open the hood.
