I developed what sounds like a belt squeal. It started off squealing for just a short time after starting the engine. It seems to be squealing longer. I looked up belt adjustment in the Hanes manual. It says this engine has a automatic tensioner for the belt. That seems to tell me that the solution isn't just tightening the belt. I'm looking for input before taking off the wheel and removing the pannels. What do you think - worn belt - bad tensioner - I just need some belt dressing like they used to have for the v-belts? Or am I to expect something more sinister like a bad bearing on a tensioner of alternater?

My 99 JXi doesn't have an automatic tensioner for the accessory belt. I believe the one for the timing belt is though. For the accessory belt, in front of the idler pulley (toward the front of the car about parallel to the ground) is a 13mm (I believe) bolt that can be adjusted to tighten or loosen the belt.

If I have time before its dark and the snow has held off, I'll try to get a photo of it tonight since I've gotta get under there soon to check out the oil sending unit.

Probably the bearing going bad in the tensioner/pulley.

Stay away from belt dressing. Belts are cheap insurance. Just buy another belt too.

My book say the 2.7 has a tensioner that uses a 1/2" square drive hole. It says to use a ratchet handle to adjust it.

It says to loosen the tensioner bracket bolt and then insert the ratchet handle into the square hole. Rotate the tensioner until the tension is right and then tighten the bracket bolt.

The auto tensioner came along in 2001.

:lol: Thanks anyway. My daughter has my old 09. She doesn't seem to take care of it nearly as well as I did. But anyway, remember that would have a 2.5L in it.

"The auto tensioner came along in 2001."

I suppose that depends on which engine you have. My '01 2.7 does not have an auto tensioner. New belt, yet I'm still plaqued with a nasty squeal if it gets wet.
