For some reason my radiator fan isnt coming on when the car heats up, this is a problem with my performance parts. It doesnt get too hot but it does run warm because the fan isnt ever coming on. What could cause this and where should I start my troubleshooting? I checked the fuses and they are fine. ugh.

 

Novi huh....Im going to say you had to mount the resistor in a different spot so the inlet elbow would fit, right? I would check your connection there first. If not, and you have a flash device check to see what temps your fan is programmed to kick in. Perhaps someone made a mistake somewhere.

 

Also, check the relay for the fan.
