my clutched cooling fan is starting to make noise on my 02. I am one of those people that looks for something better. I have looked in aftermarket electric fans. I found a kit from Flex-a-Lite that is direct fit. One question however. It specifically said to stay under 18000lbs gvw on the part description for the Ford Super Duty. It does not have the same stipulation for Dodge or GM:dunno: Does now why there would be a difference? I do alot of heavy towing with mine, so I am not looking to cook an engine.
