someotherguy Posted June 10, 2018 Report Share Posted June 10, 2018 A/C was cooling great and no funny noises until this morning. Had a noise tough to describe, then a thunk as the A/C belt popped off. It didn't break, just came off. I'm thinking the tensioner may have crapped out, but I won't have any time to check it until maybe Tuesday; working anywhere from 12 to 14 hour shifts right now. Are the tensioners a sore spot? Seems like I recall reading something about them a while back but can't remember if it was all LS's, or just LS1's (used to have one swapped into a 'burb so I had done some reading), etc. Thanks, Richard Quote Link to comment Share on other sites More sharing options...
Aldofashow Posted June 10, 2018 Report Share Posted June 10, 2018 (edited) I swapped out mine for a Gates stretch belt and ditched the tensioner havent had any Problems yet 2 years Running and its still the stock a/c compressor with over 200,000 miles Edited June 10, 2018 by Aldofashow (see edit history) Quote Link to comment Share on other sites More sharing options...
someotherguy Posted June 10, 2018 Author Report Share Posted June 10, 2018 Thanks, that's second time I've read that solution and it sounds pretty good. That's from the 2010-up application right? And, did you do this due to problems with the old setup? Richard Quote Link to comment Share on other sites More sharing options...
Aldofashow Posted June 11, 2018 Report Share Posted June 11, 2018 Ive thrown a belt a couple times and the tensioner was showing its age I found the stretch belt installed it and never looked back no more squeaky tensioner bearings also which is the best part Quote Link to comment Share on other sites More sharing options...
Downeast Johnny Posted June 11, 2018 Report Share Posted June 11, 2018 The stretch belt sounds like a great idea. First time I've heard of this fix. Looks like you need a tool to install? (Tool is $23.00. Not too bad). Gates, on their site, says feel free to contact them for help figuring out which belt you need. (Their current application chart doesn't say just which belt you need for the A/C. They also say that they are working on getting a better app page going).

Aldofashow Posted June 12, 2018 Report Share Posted June 12, 2018 I’m at work when I get out and back to my truck I’ll take a picture of the the belt part number and yes Johnny man handle the crank pulley Quote Link to comment Share on other sites More sharing options...
someotherguy Posted June 12, 2018 Author Report Share Posted June 12, 2018 (edited) I just looked up the belt for a 2010 2500hd with the 6.0; compared to the belt for my truck it's a little bit shorter which makes sense without the tensioner. Hope it's the right one...Gates K040355SF Edit - more details: 2006 Silverado SS 6.0 A/C belt = Gates K040378 978mm / 38.5" 2010 Silvy 2500HD 6.0 A/C belt = Gates K040355SF 916mm / 36" Richard Edited June 12, 2018 by someotherguy (see edit history) Quote Link to comment Share on other sites More sharing options...

someotherguy Posted June 14, 2018 Author Report Share Posted June 14, 2018 Belt and tool came in today (a day late, got $7.98 refund for one-day shipping from Amazon) pretty easy install. The tool doesn't work, flat out. Either I'm a dummy, or there's a difference in crank pulley between my 2006 and the 2010-up trucks. The tool sits over the pulley lip like it should but can't get the bolt installed to hold it; just hits the edge of the pulley flange or the front cover. So I did the zip tie trick and just tied the belt to the crank pulley, guided it around the A/C pulley, then turned the crank bolt until the belt routed on. Anybody have insight on why that tool didn't fit? If I don't need it I'm gonna get rid of it but it would have been nice if it worked.

Aldofashow Posted June 14, 2018 Report Share Posted June 14, 2018 Same I got the tool trying to do it right and ended up muscling it on by hand it stretches so its not that bad way better setup then what came on our trucks stock Quote Link to comment Share on other sites More sharing options...
