I really DID not want to change out the a/c tensioner on my 2004 Z71...but the shop told me that the horrible noise i was hearing was coming from my a/c compressor and it would need to be replaced...but they would not replace the compressor alone.... they would be installing a new compressor, accumulator or filter drier, expansion device, oil, and required gaskets and O-rings as well of new Freon. Total cost $1297.91 ....i decided to go home and investigate further....i started it up...crawled under it and started listening to everything...i felt like it was the a/c tensioner...i did the job and now their is NO NOISE WHATSOEVER! Total cost $38.86

Life saver. I have a 14 hour trip in a couple days and had no AC. Thanks man.

The belt snapped while I was driving my 2005 Z71 suburban today, and the A/C died. Turned out the pulley on the tensioner was completely seized, causing the belt to rub and ultimately break. Was an easy enough fix thanks to this video.

Great video. Both the serpentine belt and the A/C belt should be replaced at the same time. After you replace them, keep the old belts as an emergency spare in your trunk. Just in case you run into trouble in the middle of the desert somewhere!

Good job showing us what we actually need to see spot on brother.

Best video on explaining how to remove and install everything back together thank you for posting this video

I applied this info to my 2001 Silverado a/c belt replacement and now I have A/C thanx to this video THANK YOU SOOOO MUCH!!! 👍👍👍👍what a lifesaver!!!

I replaced that belt from the top side...looked like I fought a pit bull when finished...hands and arm skinned up...I should have checked your video first...thanks!!..you make it look easy..

Just a tip for anyone with 5.3 97-05, you can do this repair from the open hood position without jacking the truck or removal of and skid / splash guards. Use a 15mm +wobble+3” extension. That combo will get you past the trans cooler lines just enough to make it work. Start with a ratchet to break each side and then go cordless or pneumatic for the rest . When reinstalling the new one , do it first with both bolts already through the new tensioner for easy alignment. A drop light is helpful hung from the hood release latch. Tighten tensioner and then use a cheater bar and 3/8” ratchet to pre tension the tensioner with no hands. Then you are free to finagle the belt and release tension.

Used the info in this video to replace the a/c belt and tensioner on my 2000 Silverado 1500 today. Thanks for making this video, made the job go smoothly!

Excellent high-def video, camera positioning, LIGHTING, and verbal details!!

Great video. Some people don't cover enough information. Some people make it so long explaining every detail excellent job!!!

Torque on two bolts that hold ac tensioner in place is 37 ft. lb.

Great job MATT!, I have to replace my Daughters Tensioner/belts this weekend. Thank-you for your vid!

Hello all! Just completed this job. It can be accomplished from open hood topside. I tried going from under and could not get on to the left bolt well enough to break it loose. Too many things in the way. From the the top, disconnect air intake for clear view. Use a breaker-bar and socket for the left and ratchet with small extension for the right. For me this way was much easier. Oh, and a step stool helps too.

Thanks! made it very easy, love how you got the camera way up in there to show exactly how it goes

I have no reason to watch this, But i have to watch your videos, I love them!

Nice video. Clear short and to the point. Thanks

I made this twice already. Best I ever had 😋. And I've tried numerous recipes. It stays crispy. Thank you 🙏

You do a very good job of explaining and showing everything thank you

After 201,000 miles on my 2002 Sierra I have only replaced the Alternator, tires, and oil. I guess I can justify a new belt. My 2002 Tahoe has 188,000 miles and the AC developed a small leak. Other than that, tires and oil. Mobil 1 oil and filter (about every 8,000 miles) has my business. Good video.

Man, you just saved me some $$. Awesome video!!

Thanks, fixing to do the exact same job on my 05 Chevy Silverado Crew Cab! Great video

Talk about a step by step. Very thorough good Sir. My Chevy thanks you 🤗✌️

Thanks for posting this! I have an 04 Avalanche that desperately needs me to change the AC belt. I should have done it when I did the serpentine belt. My question is should I just replace the AC tensioner pulley at the same time? I don't know if there's anything wrong with it but it's almost at 150k. Great video btw! I don't think any of us will find an easier way. Please keep sharing these types of videos. KZfaq has become my Haynes manual! Lol (Although I always buy a Haynes manual with every vehicle I've owned. It's great to have both! Especially with vids like this. A clear view of what you're working on, good descriptions, & what tools are necessary for the job. 👍)

Hey thank you very much. Great video- easy to understand and follow. And also helps when u add in socket size -great job. Im running out now to so mine.

Good and easy explanation! Awesome

Good video..I gonna replace mine. it has 318.000 miles on it.

That was what I was looking for thanks bro.

@Max F,Excellent video brother,thank you for sharing!!

You have the best video to do this! Thanks a lot!

Thanks for making this video!

Thank you for posting this video, it was very helpful.

Dude seriously I was heading to Arkansas and my belt and tensioner were no-good, belt snapped and tensioner got it smokin, I was stressed this video was gonna be hard to understand but it was pretty darn good 👍 😅

just climbed an 11,000 foot elevation mountain pass in colorado in my 2500hd the only thing that wore out afer the trip was the ac tensioner. The truck has 350k miles ill take that small problem anyday over the dozens of cars and trucks broken down on the shoulder that couldnt make the hill!!! and we got lucky the ac worked the entire way home except the last 10 minutes

used this video when I did mine today, thanks.

Dope video man much appreciated...

Awesome video, helped alot

great vid thanks for saving me some time. cheers!

Very good video thanks!

Appreciate the video !

Great Video , thank you so much .

Thank you brother this video help me a lot

Hope my 04 Silverado belt goes that well next week 👍

Thanks for this video I can do mine now

Great video, Thnx. My only suggestion is to ensure the belt part #'s are facing the front of the vehicle, so that they can be easily read from the nose of the vehicle

Great walk through video! 👍

Great video. Thank you

Great video! Good shit!

Thank you i will be doing this to my 05 gmc.

Good job on the video. The fan was a problem for me being in the way though. I did get it fixed but that fan was a pain in the a**.

Is that remove the whole belt I took a piece of tape some duct tape and put it on certain areas on that belt so why do you have to worry about if it's going to fall off or not and that made it a whole lot easier for me myself that's the small tip

Thank you sir. For the help

Great video

My 2004 Silverado 1500 V8 A/C Compressor Belt snapped while driving. I usually overspend so I decided to just replace the A/C Compressor Belt. It was my first time swapping it but the A/C Compressor Belt Tensioner for sure didn't look right visually with the new belt installed. I figured I might as well test out the $20 belt to see what happens and sure enough there was a burning smell within 5-10 seconds coming from the engine. I let everything cool off and inspected the belts. The A/C Compressor Belt was being burnt by the contact surface of the A/C Compressor Belt Tensioner. It definitely looks like my tensioner isn't even spinning. It looks like I shouldn't have skipped out on buying the A/C Compressor Belt Tensioner as it definitely needs to be replaced.

Thank you for The video

A stretch belt from a 08-13 works a lot better and you can delete the tensioner save money and works better

That deepwell socket is the key here.

Worked on fixing my AC in my 2004 escalade , new belt and tensioner

Thank you dude

Can I run my engine without the AC compressor belt? I'm asking because I am trying to determine where an annoying sound is coming from. I can't tell if it's the serpentine belt or the belt to the AC compressor and I already replaced the tension pulley and the idler pulley for the serpentine belt. Also I noticed that my tension pulley for the belt that turns the AC compressor haves a slight bounce to it, is that normal or should I replace it?

Will the tensioner affect ac blowing warm air while idle Have everything new only the tensioner is old i did replace the ac belt though

Do you have the 105 amp alternator? I’m getting ready to change all my belts and tensioners. Looks very simple. Video helped me out. Thanks.

Thanks!

Do you need to tongue the bolts on the a/c tensioner and drive belt tensioner?

Awsome 💥🙌

Any tips for people with a fan clutch assembly?

Thank you

How did you get the bolt in the back off

What length is the belt you used I can’t seem to find the right one

I replaced AC tensioner with the belt on my 01 GMC Sierra but tensioner is still shaking. Any advise? Thanks for the Video!

Do you know what the thread pitch on the tensioner bolts are

Nice video. Looks like you did it the easiest way to me. I came to this video because i just changed the water pump on my girlfriends uncles 2005 chevy Silverado which was very easy by the way. But we noticed the belt on the ac compressor was cracked so he wanted to change it as well but his AC does not work so to my knowledge cant we just remove that belt all together if hes not using his AC?

Hi there. Thanks for this tutorial. I am a beginner so I hope you don't mind my simple question. I understand that changing the belt is important to prevent the ac system to suddenly stop working but what's about the tensioner? How can I tell if mine is broken too? Is it something that should be replaced in advance as well?

Ty sir

El apretado del tensor de la banda es al toque o es con torque

Thanks

I have 2001 tahoe with 4.8 but it keeps snaping the ac belt and braking the ac belt tensioner the ac gets really cold until it breaks the compressor is not seized i installed the compressor like 3 years ago any ideas

did you have to take main belt off first just to change ace belt

I replaced my tension pulley but it still wobbles even tho its brand new. Is it because the ac compressor? What else might be the problem i wonder

I wanted to know if the bolts had washers or not

What was the part number for the a/c belt?

What conditions cause u to replace tensioner?

I have a 2004 Yukon Denali, I bought a Dayco Poly V belt for the AC and it seems small. I watched this video and noticed you didn’t have to fight with the belt like that. You were able to put it around both Crankshaft and AC compressor pulleys before using the tensioner. I can’t even put this Dayco crap around both pulleys so I think I have the wrong one. I should not be here struggling and fighting with this belt if it was truly the right size

how big is the belt you put on?

Hey man I put my ac belt on and it’s making like a rubbing/knocking noise and I’m not sure what’s going on because when the belt was off it wouldn’t do it

Did your pulling make loud grinding sound ??

Where did you buy the tensioner

I put a new belt on my Tahoe cuz the old one was broken and when I turn my ac on the belt broke of again what could be the problem?

Would this make your ac not blow cold??? I just got a new compressor Freon new fan clutch cleaned out the filters and fan blower opened the cold circulation to the blend door actuator. The only actuator I haven’t got to is the recirculating actuated doing that soon. I can’t figure it out. The canister under the hood is nice and cold and got everything done by a good mechanic with good reviews.

What Am I Doing Wrong if I Can't Get My AC Belt On Its Like It Dont Fit But I Have The Right Belt Fasho

💪💪👍👍👍

how would you diagnose a bad ac tensioner pulley?

My question is...will the absence of the ac belt cause your heat not work or blow?

Is the ac tensioner the same as the drive belt tensioner??? If so part##

Would a bad one of these cause loud sqeeking?

A bud can I still drive my Tahoe with our a tentioner belt until I can get one

I replaced it but now the compressor turns on and off on and off etc you know what it could be?

You ought to try this on a v8 Trailblazer! Spoiler alert....... The Fan & Shroud have to come out! I'm just skipping up& down the driveway!

Can your AC tensioner cause your AC not to blow cold
