Last summer I was overheating and replaced my fan clutch and t-stat. Never heated up till recently and the fan did not turn on. I've hosed out the radiator from both sides and there was'nt an ring of oil from the oil bottle. I haven't flushed my cooling system. How do you flushout the cooling system. I don't know what to do about the fan not turning on. This really sucks.

 

Anybody? Trying not to go to the dealer.

 

Slugblaster dont give up yet my buddys 2000 is doing the same thing as yours he is on his second fan clutch n t stat look for my post in the help and the 24valve section i posted twice to get him back on the road

 

check your fan clutch relay...under the hood drivers side lil black box with relays...swap it with another relay there and test....oh yeah and check ur codes

 

I don't think there is a fan clutch relay

 

Never seen a fan clutch relay on these truck unless...its an aftermarket fan on the radiator..
