I took of the fan belt and drove it for a quick drive through the gears and it made such a difference I couldn't believe it. Currently it has the factory fixed blade fan. I am wondering if anyone else has ever noticed this on these trucks? Can I run a clutched fan on the truck?
I would like to know what to order as I know that the fan has to sit in the radiator fan shroud correctly so it draws the correct amount of air.
any suggestions on what to try?
His dad must of put the fan spacer between the water pump and the pulley instead of between the pulley and fan. Bet he had a hard time finding a belt for it. lol
