What does a radiator fan do?

Your BMW’s cooling system helps keep your engine from overheating. The fan spins rapidly, removing heat from the coolant in your radiator. Because liquid conducts temperature more efficiently than air, your coolant is more effective than simply blowing cooler air on the engine.

How do you know if your radiator fan needs to be replaced?

The fan is a resilient part, so it rarely needs to be replaced. Unfortunately, if your radiator stops working, the damage to your BMW could be catastrophic. When changing your coolant, check to see if there are leaks or damage that might signal a problem with your fan. Here are some other symptoms of a bad fan:

  • You cannot hear fan working while stopped
  • Your engine temperature rises rapidly even with light use
  • Your check engine light comes on
  • Your BMW overheats

Should your radiator fan be working constantly?

The BMW 540i radiator fan turns with a belt that is driven by the engine. When your car is running at cooler temperatures, your fan clutch should partially disengage this drive. This keeps your engine from needlessly using too much energy. If your fan is working all the time, even when your engine is cool, there may be a problem with your radiator fan or fan clutch.
