I replaced the serpintine belt on my 90 4.0 liter along with the idler pulley and fan clutch to cure a very loud bearing squeal that was coming from the front of the moter. Worked like a charm except when I put it all back together the belt is not centered on the fan pulley, it wants to ride near the back of the pulley but every thing is in perfect alignment and is running true. Can someone check there vehicle and tell me where there serpintine belt sits on the fan pulley???

Fan Pulley Question

Checked the HB,no seperation ,looks great. My problem is that I can not tell where the belt was running on the fan pulley before I changed every thing. The vehicle works great except that common sense tells me that the belt should sit on the center of the pulley. FSM says nothing. Could you check your jeep and tell me where the belt rides.?? Thanks

The belt has to be centered on the grooved part of the pully. If it's not this way, then one or more of the belt's ribs will be riding on the part of the pully that doesn't have grooves. I think there one groove for each rib, no more and no less.

Same here. Tends toward the rear half of the idler.
