I made custom mounts and mounted an a/c fan on my radiator. the plug on the a/c fan is identical to the radiator fan's plug. I figured that might work better than the other fan, because its way thinner. Anyways, the fan wouldn't turn on the other day, and my car started to over heat. I didn't know if that was a fan problem or a sensor problem?

any help would be apreciated!

thanks,
Rob
