I have my fan wired to a switch,and I keep it on most of the time car runs around 165*,the other night I was sitting at a light and seen a little SMOKE rise from under the hood,checked it and found out the fan quit.I washed the car earilier and figured I smoked the fan relay,installed a new one,wasnt it.Someone told me my fan clutch could be the problem(i didnt know they had one).I called auto zone,they said they had thermal or non thermal?ANY SUGGESTIONS PLEASE ?
