1991 Jeep Commanche squeaky noise

I have replaced the idler pulley, belt, water pump and atlernator and still have a bad squeak. If I spray a shot of wd 40 on the belt it will quit for a minute. Any ideas?

Thanks,

James:confused:

Does it squeak all the time, or just after startup? Do you have the automatic tensioner, or the one that is adjustable? Is the squeak in the belt itself or one of the components?

And now that you have gotten wd-40 onto the belt, you should get it clean. Try squirting laundry detergent on the belt, first while stopped, then while running, and while running rinse it well with a garden hose/sprayer.
I would want to make sure the squeak was not due to a bad viscous drive fan clutch.

serp belt?

Does it have power steering? could be the pump getting ready to go.

Guys, I think since bassjam hasn't replied for over a year, he's probably not going to.
