I've searched the forums, but none of the questions relates to my issue. I have an '03. The belt started squealing, and also making a slight ticking noise, much like a stuck lifter in an older car. Noticed tensioner pulley kind of bobbing. Belt was obviously loose as I could turn the alternator pulley by hand. I bought a new hydarulic belt tensioner and a new belt. Here's the odd part, with the new tensioner in place with the new belt (which laid on top of old part is same length, belt and tensioner), the belt was now LOOSER than the old unit. I've worked at an auto parts house for 20 years, and have never seen such a thing. I had to resort to a belt that is .300 inches shorter than the recommended belt. Any ideas? My listing for the "correct" belt is 45.8 inches long, what I ended up using was a 45.5 inch belt. I still have a little squeal at start up if AC compressor is engaged....that could be age on the compressor as it has about 197k on the van. I even looked at the harmonic balancer, and other than stress cracks on the rubber ring, it doesn't appear to "wobble" as if it were going to separate. Compressor pulley freewheels as it should and alternator bearings seem fine. Sorry for being longwinded, but I wanted to post as much info as I could. Thanks for any help.
