I am replacing my radiator on a 85k5 I am also replacing all the hoses getting ready for summer. Can I get a more efficient fan type? What about removing the Fan clutch? Will this also help to keep my rig cooler when towing a trailer? I just bought thisd rig and this is my first project. i want to make sure I do it right from the beginning. thanks for any help AL "Measure twice cut once"
