I put in a fan clutch on my f150 from a mercury only this is it is shorter, the clutch so the blades are further from the radiator is this bad or does it matter its like a 2 or 3 inch difference I think?

 

Mike, hi and welcome. I deleted the same thread you posted on this in the intro forum.

I'm sure you'll get better responses here and wish I knew enough about what you've done to advise you myself. I'm sure some knowledgeable member will be along soon though.
