Did this video help you?

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?

Michael Stanton: I just changed my ac belt and now my battery light is on and it's saying battery not charging. Any suggestions?

TheBrittbrat2341: Would the old tensioner need to be replaced if it doesn't spin at all?

chacho sanchez: @1aauto thanks for the tip...i did replace it and i was surprised at how simple a job it was..the video was a huge help!!!

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.

Erik Luck: I've never changed the tensioner out, but after watching your video I figured no sweat!The new belt and tensioner took me and my son the tool handler about 45 minutes.Great video ,I've already passed the site on to all my buddies for their issues. Thanks E.Luck in Ca.

johntaheri: Hi I got a 1999 buick century with 3.1 I notice 2 mesh type hose next to ABS 1 connect to ABS controler but the other one is broken but i don't know where is connected to please if you can help thanks john

Cassie L: YES THIS DID HELP! even though i wasn't replacing those belts....I was replacing my alternator

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

1A Auto Parts: @ErikLovesHorror Thanks for helping to spread the word Erik, it's greatly appreciated.

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?????

moises gonzalez: thank you.

chacho sanchez: this video is of great help..question though? is it best to replace the a/c belt with the same factory belt? any suggestions?

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.

rlhernandez77: What is the part number for those the tensioner and belt?

JustinCase380: I second that. Every Haynes or Chilton book would always leave out a part and watching someone do it is great. Having a video for almost everything is awesome. Thanks to Youtube for having all this great stuff and double thanks to the people who create and post these helpful videos.

recykaler: All I can say is 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

SuperDavide11: I just did my 2003 Silverado and your video is RIGHT ON . Thank you.

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.

artem5708: Thank you guys Video was helpful

kenman1717: i do alot of ac belts. a fair amount of tensioners aswell but not as much. our service manager tells us that when you spin them if they spin really fast they are dry on grease and should be replaced. yes we check to see if they move back and forth as well. but obviously we only check them if there is a noise compalint from the belt area or we are replacing a belt.

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 ??

muertos al pecado: Your video is super super the best is my firsts time changing the AC bell and I did it right

johntaheri: thank you very much for the tip.

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?

TradeMark2003: awsome. thanks for the video. Now ive heard that when the tensioner starts rattling, usually the compressor will be on its way out too. is this true? I wouldnt think so but it doesnt hurt to get another opinion. Thanks again.

1A Auto Parts: @sanchezlw13 If the belt is cracked then I would replace it with a new one.

1A Auto Parts: @recykaler You're welcome. Thank you for checking out our videos.

1A Auto Parts: The serpentine belt tensioner should place enough pressure on the belt so that it doesn't squeek. The serpentine belt tentioner or belt may need to be replaced.

1A Auto Parts: If your tensioner is not spinning you will need to replace it with a new one.

guardiola2000: @trademark I herd the same thing from a mechanic I would like to knw if that is true ? also ... I think they just wanna make money of us

stickysugarpuff: how do u tighten that ac belt? when i pres up on the pully you replaced by useing the 3/8 ratchet and thus tightening the belt it stops squeaking.

GooseBMW: Great video, I just watched it, then went out and actually DID it in about 20 minutes.

22jrrped: Thanks for the video. Got rid of my dreaded squealing noise. I didn't even have to pop the hood. You can leave the serpentine belt on. Easy 10 min fix.

1A Auto Parts: @gonmoises The tensioner will automatically put the proper amount of tension on the belt.

BillyWas2011: Thanks for the video; however I changed the AC tensioner and AC belt but I am still hearing a clicking noise when I rev the engine with AC on. This only happens when you first start it. After it has been running awhile with AC on it won't make the clicking noise. I also noticed that when AC is on, car idles a little rough; more so than normal. Could it be the AC compressor causing more resistance than normal? I read somewhere you can lubricate the compressor with special oil? If you can giv

Hack Amore: 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.

1A Auto Parts: The tensioner is 1AEBT00024 and the correct serpentine belt can be found through the link below. You will have to match up the correct options on the vehicle to the listing on the belt: 1aauto.com/1A/SerpentineBelts/Chevy/Silverado1500/-/-/

moises gonzalez: How do i know if the belt is too tight? I changed the the serpentine belt and the tensioner has almost no slack left.

1A Auto Parts: @johntaheri Here's a link to that hub on our website. It will show you where that harness plugs into the hub. Hope this helps you out. 1aauto.com/1A/wheel-bearing-hub-front/Buick/Century/TKSHF00002/502944/1999?utm_source=youtube&utm_medium=youtube&utm_campaign=1ATony

lady3bglover: Thanks so much for the post. Very easy switch! I would have like to go underneath, but my husband has all 4 jack stands under his Honda. Fortunately my ride is on a 2/4 drop and I used an old stock wheel to get up and over. I got a little lucky b/c I didn't have to deal with the clutch fan, it's long gone.
