1A Auto Parts: @Larry Foster It shouldn't move too much. If the tensioner's moving up and down quite a bit, it may be a bad tensioner.
Larry Foster: Great Video! With the veh running should the AC belt tensioner be moving? (it looks like its skipping up and down 1/4 to 1/2 inch) 2004 GMC Yukon 4X4. I just replace the idler and tensioner for the serpentine belt, wondering if some noise could be coming from the AC belt?
legit customz: My belt broke off of the compressor... It sour make a noise only on acceleration and would smooth it self out..what could the problem be
Mack Mcgregor: i used this video to replace my ac pulley .great job on making it easy for me. thanks!
Robert Ahmmo: I changed my belt once and it broke. I then changed the pulley and belt and the AC worked but after a few days the belt broke again. What is the next step?
Dave Carter: ac belt 99 gmc sierra
Michael Stanton: I just changed my ac belt and now my battery light is on and it's saying battery not charging. Any suggestions?
Chris Green: i used the video as a guide and what tools I needed but I didn't need to remove intake or skid plate like recommended. I have the 5.3 so maybe there is more room but I was able to reach the bottom tensioner without removing the skid plate. also I have an aftermarket intake so maybe that is why I had more room to reach the upper tensioner.
muertos al pecado: Your video is super super the best is my firsts time changing the AC bell and I did it right
muertos al pecado: I did my chevy suburban 2003
SuperDavide11: I just did my 2003 Silverado and your video is RIGHT ON . Thank you.
1A Auto Parts: You may want to inspect the clutch assembly on the AC compressor to see if it needs to be replaced. 1aauto.com 888-844-3393
1ghuck: I have same problem. Changed Tensioner, both belts, thought maybe...... nope same thing, noise when a/c on, no noise when a/c off. Tensioner for a/c vibrates really bad when a/c on, and is just a little better when a/c off. This all started 2 days after changing blower motor resistor ??
Robert Rodd: I just did this on my 2008 Tahoe, and it was a little easier than shown. The tensioner for the serpentine belt is located so that it can be reached easily without removing the air intake. And, although you use a 3/8" wrench with no socket on the A/C tensioner, on the serpentine tensioner it took a 15mm socket. The whole thing took 30 minutes, tops.
Christopher Thayer: Your a/c compressor could also be locking up. You'll know if it is by the terrible sound it makes. It'll sound like a terrible ratcheting noise under the hood when accelerating with A/C or defroster on.
1A Auto Parts: The issue could be with one of the pulleys or it could be the tensioner is not holding down the belt correctly.
AJ Ramos: I replaced my belt, but it kept making noise whenever the ac is turned on but eventually stopped, so I ignored the noise and now the belt has snapped in half. The belt lasted a couple of months. Any suggestion on what I should do or what I did wrong?
1A Auto Parts: It could be. You may also want to check the AC clutch on the compressor to see if it's making noise.
innsac: I have a Chevy Tahoe that make a noise only web the ac is on and pasted 1500 rpm do you think that it might be the ac belt tensioner?????
1A Auto Parts: Yes, if it's frozen then it would need to be replaced. We carry new belt tensioners for all kinds of vehicles on our website 1aauto.com 888-844-3393
