radiator fan

[dave1243]

I don`t think my radiator fan is working (temp goes to half way on the guage and fan isn`t running). Is there an easy way to check to see if it`s the fan or another problem?

The radiator fans won't operate unless the coolant temperature is approx. 210F. Make sure the coolant is getting hot enough.
The Coolant Temperature Sensor (near the thermostat housing) triggers the PCM to turn the fans on. If you have a VOM/DVOM the CTS can be checked.*
Check the radiator fan fuse (40A) in the Power Distribution Center.
If you want to check the fans, you can disconnect them and run a fused jumper wire direct from the battery (+).

*If you decide to check the CTS and need help let us know.

to check fan just start engine then disconnect coolant sensor rad fan should start this is built into the pcm program fan defaults on in case of faulty coolant sensor keep in mind a fault code will be generated by doing this so just disconnect battery for approx 20 minutes after to clear codes
