Q: Overheating when fans off

asked by on

If the air conditioning fans aren't on, my car overheats.

Hello! It sounds like the system is working properly. The fans are designed to turn on when the engine reaches a certain temperature. However if the fans do not work properly the vehicle will overheat. If the vehicle has an overheating issue I recommend that a technician check the performance of the fans to ensure they are coming on at the proper temperature. If they don’t, you may have an issue with the fan itself, fan relay, or the coolant temperature sensor. A technician, such as one from YourMechanic, will be able to inspect the said components for faults and help determine why your car overheats.
