Re: 2-Part Cooling Question

Definitely install a shroud. A stock clutch fan is fine as long as the clutch is good. You can test it by putting a piece of masking tape from one blade to the shroud. Drive the truck a while til it warms up. The fan should have engaged and broken the tape. If not, time for a new clutch.

Also, are you certain your radiator is in good shape and not clogged? Same goes for hoses. Be sure they are not soft and the suction side isn't getting pulled flat by the pump.
