Help me with this Duramax belt please. I have a video!
First of all, the idler pulley between the compressor and the alternator FELL OFF the other day. It was replaced by a guy I wouldn't trust within a mile of a wrench, but he tries.
Is this even a California truck?
Now it's making this horrendous clicking/ grinding noise. It sounds very, very much like it's coming from the tensioner. It goes away entirely if you give it a couple hundred RPM and then comes back when you drop it to low idle.

Anybody ever hear that before? Tensioner? Or is something routed wrong? Can it just be taken apart and lubed perhaps?

Come on Photobucket, how the hell does an 8-second-long grainy video of a belt tensioner violate terms of use?
Please see attached video.
I can de-tension the tensioner with a ratchet and spin the pulley on the end; it's spins great. All the rest of the pulleys feel good. I think the noise is coming from the spring-loaded side of the tensioner. If I push down on the tensioner, it stays down...

According to my wholesale company I use, a Goodyear belt tensioner part # 49278 is $57.49. A regular auto parts should be comparable and Delco might be a tad more, but not $200.

For some reason, the ac compressor plays hell on the tensioner. Look at the ac lines on the compressor, it has 2 'mufflers' on there. That was to help with the constant vibration, but it still hammers the tensioner.
I've had a few pully problems on my work trucks, but usually it's on vehicles over 200k.
