Replaced the Tensioner pulley "Took only 5min" and the chirp is gone.....
Spun the old one when I had it off and there was a bearing rattiling in there.
Glad to hear it.... I have replaced 2 on my 95 Bonnie so far... Funny tho the one on the 91 LE is original( so far )...

Glad you got it fixed Nick

I got a follow up question. I am getting that same chirp. It really only happens when the car is in park, or at a low idle (stoplight, traffic, etc..) I have had it in a garage allready, and they replaced the Waterpump and some other tensioner on it. I cant remember at this moment what the name of that tensioner was, but is there more then one that could cause that chirping noise? The one I had replaced was rather big, needless to say none of what the mechanics did fixed it.

Mine was the same problem, low idle and or speed and park.
If your car is a non SC engine I know of only one tensioner, it sits above and to the left(toward the fire wall) of the waterpump or below and to the right of the Alternator.
Make sure the belt is in the center of the CRANK pulley, if it isn't, it will actually cause the tensioner pulley to chirp a small amount, Dont ask me how I know this, I just do

I believe each of the motors have the tensioner plus at least one idler pulley. The chirping could be an idler pulley as well. Idlers should have normal threads and not reversed. TMK the only pulleys with reversed threads are tensioners.

im glad you could figure it out. one time i had a squeak and i thought it was nothing major so i didnt immediately fix it (the squeak only started about a week before it all happened), so i kept on driving it and basically what happened was there was a big bolt against the belt (really far down under the belt where i couldnt see it and i have no clue how it could have loosened like that) and the bolt had somehow came loose and was cutting my belt and the belt snapped in half and shot dust everywhere and luckly didnt wrap around anything and rip things apart. At first I thought i broke an underlight because I had just made new brackets, so I pulled over, looked under the car and the light was ok so then i started to investigate and popped the hood and yah you can only imagine how i felt. i pulled off the road within a split second of it happening and the person behind me almost hit me because i made a fast break and turn. just goes to show you...if you think something is wrong, take a couple of minutes to look at it, even if it seems minor. I felt so stupid because if i looked at it I probably could have noticed the big groove being cut into the belt.

Wholeheartedly agree.

Cars make noises to tell you something isn't right. Many of the noises we hear were engineered in over the years.

Brake pads and the feelers on them.
Sounds of a power steering pump getting low on fluid.
Trans slipping.

None of these will usually harm the car in the short term. They are the warning signs.
