Ive done a bit of reading but have not found all the answers to my questions. I have a 2004 Gmc Yukon Denali and it has a clutch fan. It had been replaced within the last year along with a cold case radiator, belt, and etc but it is loud when driving most of the time I turn the a/c on. I want to get rid of the clutch fan to free up some power and make the truck more efficent also. As you know the a/c isn't as cool as it can be while idling if air isn't flowing throw the grille. My question is what all do I have to do to swap in the electric fans and what do I need to get besides the fans and relay?
