I have a 2009 386 Pete with a 485 ISX. The fan belt squeals sometime when the AC is on and the engine fan kicks on. A while back I replaced the fan belt, then the belt tensioner and finally the crank pulley. The belt still squeals from time to time but not as bad. I was killing time on QuickServe and noticed under Manuals, then Installation Instructions Number: 4907798 Fan Drive Idler Pulley Assembly. From the drawings I thought it looked like it would help with my problem. So I bought the kit, but the parts will not fit behind the fan pulley. Has anyone tried to install this kit?
