I have a 1988 s1600 International with a 7.3 diesel. I currently have it torn apart and found out my radiator needs to be replaced. I want to replace the fan clutch with electric fans and a newer aluminum radiator. Has anyone tried this? I figure while I have it torn apart i might as well upgrade everything, I'm just not sure what radiator I can use. I won't be doing much towing with it and i live in Florida, so there aren't hills to worry about. Plus this will be more of a low rider then a heavy hauler. I've swapped out the rear axle with a 96 dodge 3500 rear end already.
