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?

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
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.
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.
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.
muertos al pecado: I did my chevy suburban 2003
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
1A Auto Parts: If your tensioner is not spinning you will need to replace it with a new
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
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
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
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.
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:
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.
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.
