There seems to be a lot of confusion when people try to replace cooling system parts on our older Jeeps. It's not just swapping out one part with a different type as fittment and compatibility come into play. The three major factors is depth of water pump/ pulley combo, fan clutch or fixed fan, and radiator depth and shroud. All three need to match in order to work together with proper spacing.
If your radiator is hitting or too close to the clutch, I would guess your either have a fan clutch when you shouldn't OR you have a radiator for a fixed fan system when you should have a deeper offset one for the clutch. Do you have a shroud? Those are mainly used and come with the fan clutch system
