Why is my radiator fan not working on my Acura MDX?

If the radiator fan is not working on your Acura MDX, there could be several reasons for this issue. Here are some possible causes to consider:
1. Faulty relay switch: The relay switch controls the operation of the radiator fan. If the switch is faulty, it may prevent the fan from turning on. You may need to locate and replace the relay switch.
2. Coolant level: Low coolant levels can cause the radiator fan to malfunction. Check the coolant level in your vehicle and add more if necessary.
3. Blown fuse: A blown fuse can also prevent the radiator fan from working. Check the fuse box and replace any blown fuses related to the radiator fan.
4. Fan clutch: The fan clutch is responsible for engaging and disengaging the radiator fan. Over time, the fan clutch can wear out and fail to engage the fan properly. If everything else seems to be in order, the fan clutch may need to be replaced.
It’s important to note that these are just potential causes, and a proper diagnosis by a qualified mechanic is recommended to determine the exact issue with your radiator fan.

What sensor turns on the radiator fan?

Yes, the coolant temperature sensor is an important component in controlling the radiator fan in many modern vehicles. The coolant temperature sensor monitors the temperature of the engine coolant and sends this information to the engine control module (ECM), which uses it to determine when to turn on the radiator fan.
