I got a 99 grand with a 4.7 and the fan clutch dumped on me. Dealer tells me that it takes 50 horse power to turn and that it would cost me about $400. to fix. (part being $200) I found one for $55 dollars and can change it myself,but I was wondering do I even need It ? to give me an extra 50 horse would be awesome,and there is an electric fan. I dont go off roading with it so it's not under alot of load.I am concerned though about the summer time and keeping it cool. any help would be great.....
