Hey boss,can you help me fix my truck 😔
This video saved me $1000.00 dollars. I was told by a shop that my compressor was bad and that the system wouldn't take a charge. I crawled underneath and discovered the AC belt missing completely. I installed the AC belt and a New drive belt. I vacuumed the system and charged it. AC is cold as ice again. Thanks for all the videos.
We're glad the video helped you out. Thanks for watching. 1aauto.com 866-403-3393
I can't stress enough of how important your videos have been in helping me repair my truck.
+constellationpegasus Congratulations on the successful repair. We're glad the video helped you out. For anyone else looking to change out the belt, we offer it at the following link: www.1aauto.com/1A/SerpentineBelts/Chevy/Silverado/1AESB00053?TH-cam&CTA%20Comment&ATony
Ive watched many of your videos and truly appreciate all of your efforts to help us out. I always gain the "do it myself" confidence and get it done right. Thank you very much!!
We’re happy to help and thank you for watching 1aauto.com 866-403-3393
Great video - only one very minor item worth mentioning. In your companion Silverado video about the serpentine belt, you might want to mention that if you're doing both belts at the same time (like I was), do the AC one first. :)
Ive practily rebuilt my whole truck from these 1 a auto.videos.thank you.
1A Auto: Just changed out my AC fan belt and it took about 5-10 minutes and all is working well. Takes about as much effort to change a light bulb, had 2 quotes both around $160 for a 5 minute job. The air intake took a couple of minutes to wiggle out and put back on.
Thanks for the video, saved me $$$ now I'll go out to have a nice dinner.
Thank you for watching. Please let us know how the repair comes out!

No problem, all works great, had enough room from top that I didn't need to remove guard plate.
Thanks for this video! My ac belt snapped on my 01 Tahoe and this video showed me how to replace it myself. All done in about 35 minutes!
This video was great. I'd been stalling throughout the winter to replace the ac belt on my 2000 Z71, thinking there was no way I could do it. But today I thought I'd give it a shot. Confounded, I used the power of Google to search for tips and this video came up as an option. I watched it and 30 minutes later my AC is back to working!
Ive found you can do this from up top. I mean, I'm tall and have long arms and can reach down to get to the ac belt tensioner. I can see why some might need to remove the lower shroud but not really necessary.
You guys do a nice job on these videos. Talk about important points and speed through the obvious.
Great video. I honestly did not know there was a separate drive belt for the ac on my 2003 until I saw it hanging down, broken. I guess that explains the noise I was hearing before it snapped. I thought it was a bad pulley.
Loved it. Saved hundreds of dollars on such an easy task, fixed my ac before I finished my caguama 👌
+Marko Martinez Thank you for the reply. We love to empower our customers by showing you how-to perform your own auto repairs while installing our high quality auto parts. Have a great day! 1aauto.com
THANK YOU!!!! You’ve saved me a lot of money. I NOW HAVE AC AGAIN!
I noticed you replaced both tentioners at the same time. I couldn't tell if you replaced the idler pulley as well. Always a good thing to do if your truck has a lot of miles
Dealership that I got my truck from wanted to charge me 300 just to replace the belts. So thank you for this video so I can save 200+
+Dawson Brown Thanks for watching. If any of our viewers needs to make this repair, we carry the auto repair part shown in this video on our website. Here is a link to them www.1aauto.com/1A/SerpentineBelts/Chevy/Silverado/1AESB00053?TH-cam&CTA+Comment&M5R0YzfqyHw
Great video. I appreciate you taking the time to make it. I have an 04 Silverado that had a compressor belt that was really worn. The compressor seems to be fine spinning freely. I have a new belt to put on. This was helpful.
I've seen a few 1A videos now ( good work by the way ) and able to hundreds with their videos. So I needed to check pricing on their website to compare with other onlines. They are right there WITH FREE shipping. I'm not sure this is mentioned enough. Parts ship same day as ordered before 4pm. They have a warehouse on EACH coast to speed delivery. Give these guys a chance is what I'm saying. I'm certainly going to. BIG THANKS to 1AAUTO ! !
+David Davis Thank you for your order, and thank you for the plug! If you would like to leave us a review on Google it would be greatly appreciated. Here is a link to our reviews section. Have a great day! goo.gl/i5JFNY
The serpentine belt tensioner should automatically apply enough pressure to it so that it doesn't squeal. Over time the tensioners can loose some of their tention and need to be replaced. Hope this helps you out.
15mm bolt for belt tensioner on AC compressor. I got to both tentioners from below just fine and got the new belt on. Great video, AC works!
If you are getting a mildew smell coming from the vents, you might have cabin air filters that were installed in the vehicle that need to be changed out. Some of those vehicles came with them, others did not so you will have to check it out.
We currently do not carry this particular part. Thank you for asking. Have a great day.
Thank you for this video, it helped me to replace a broken AC belt. Perfect descriptions as always. The longest part was figuring the main serpentine route, even from the diagram. Tip for me to remember, basically pinch it in between the two idler rollers so the flats are back to them.
+Debi & TJ Jensen Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c
You may be able to install a shorter belt to by-pass it. Some vehicles will have two different belt routing diagrams one with AC and one without.
Perfect. Thanks for the step-by-step talk-through, good camerawork and naming the sizes of the fittings. With the help of this video, I replaced both belts. Unfortunately, it turns out the screech I hear when I turn the motor on is now likely due to a bad A/C compressor. Anyways, I appreciate your informative video.

Very Helpful video. Its great to have a video like this to help you out when your trying to do repairs yourself. Thx
On that particular year I'm not 100% sure. You may want to ask the dealer, they could tell you if your vehicle came equipped with one. Hope this helps you out.
Great video! Just saved me $200 by doing it myself!
+Chad Wilson That's our goal. We're glad we could help you out. 1aauto.com 866-403-3393
Really saved me money! And I feel a little more knowledgeable being able to learn things for myself
Do you need to replace your drive belt as well or can I just replace my A/C belt? Is it better and recommended to do both?
You can just replace the AC belt but if you’ve never replaced your serpentine belt, I highly recommend changing both
It may fit snug but shouldn't be impossible either. If it's a new belt, measure it against the old belt to see if it's the right size and not smaller.
@1soccerkid If the belt is loose the belt tentioner may need to be replaced if it's not holding enough tension on the belt.
My 99 Sierra 4.8L doesn’t have a tensioner, it’s more like a Manuel tension that you tighten/loosen with a bolt. I can’t find anything in this... can you help please?
1AAuto, your videos are really helpful, thanks for your work!
Thank you for watching. Please let us know how the repair comes out!

If the issue is only when it happens when the A/C is running, there might be a bad bearing either in the pulley or there could be something wrong internally in the compressor.
Very informative video. Followed the steps exactly and had no problems whatsoever on a 2002 Yukon XL. Thanks!
+A.P. Ware We're glad the video helped you out. Thanks for watching. 1aauto.com 866-403-3393
Looks like a shiny new tensioner you have there... I'm replacing mine right now. Good video. Shows what I needed to know.
+Mike Brown Thank you for your feedback!
@@1AAuto My tensioner was bad, I replaced it and the AC now works, but it's not super cold. Any suggestions?
I bought my grandpa truck it’s my first and need this now I know for tmr what to do thanks so much
is there some kind of trick to get a "new" belt over both the crank and a/c rings...i tried over and over different methods but it never seemed to be enough slack in the belt to go over both....
U made it look real easy and simple, thank u.

Thanks save me a lot time and money
Just wanted to say thank for all your help thank you u will share 😊
Great vid, main belt easy. Ac belt hard. Thanks
Great videos! Looks like I have my
Next day off project before winter!
The AC compressor needs to spin with the belt in order for it to work correctly.
Awesome demonstration, Thank you. I did it very easily following your video.
Thank you for watching!
1aauto.com 888-844-3393
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.
Just want to say thank you for the awesome video. As with others it helped me save time and money. Very much appreciated.
+nick hammett Thanks for checking us out. 1aauto.com
very helpful videos i have question i need ac belt for 2000 silverado 2 auto parts store sold me belt that wouldn't fit said that was only one they have where can i get belt that fits
I've had two suburbans and they've both thrown these same belts if they do should I buy the tensioner pulls new?
Sometimes my AC belt jumps off the crank and compressor pulleys altogether and I’ll find it just dangling there. How does this happen? New belt and new tensioner!
sorry, my 1992 chevrolet silverado, the switch on the compressor, is it replaceable?
I appreciate yalls videos!
+Jared Powell Thanks for checking us out! 1AAuto.com
Great vid. The ac in my truck was coming out in in pulses. Slowly it stopped working less and less. Now is doesn't work at all. Could this be do to the belt?
Nice vid... i noticed you replaced both the tensioners also, would you say this was necassary or just preventitive maintenance??
I noticed that they were worn out, so we replaced them.
thanks, great video, done in 20 minutes!
very informative video..this helped me replacing my a/c belt on my 01 yukon xl. the a/c belt is still slipping after replacing the belt and tensioner and only slips when a/c is on, not when it's off. doesn't slip at idle either, only when i accelerate. a/c cools very good at idle which it didn't do before i swapped to a new belt, it just blew out air that smelt of mildew. could my clutch be locking up or my compressor going out? also, what would cause the bad smelling air? thanks for helping
Okay I watched this video... the problem is my 2011 Silverado 1500 with 5.3 does NOT have that tension release bracket on the a/c compressor. Is there another design on the 5.3 that I need to look for to release ac tension?
I just bought a used 02 Chevy z71 and the air doesn't work and when I try to put freon in it just acts like it won't take it I just noticed that the ac belt isn't on, do you think that's why the air doesn't work and why it won't take the freon? Thanks for your time and helpful video any help would be greatly appreciated and thumbs up!
@mikeaa000
I have having the same problem. From what I've been able to find, it's most likely the AC clutch that is locked. If you call a dealership, chances are they won't replace just the AC clutch, but rather the entire compressor - my dealership quoted my 900-1500 bucks. At that rate it would behoove me to just buy a new vehicle (2000 silverado - 188K). But I was able to find a place that will replace the AC clutch as they have the required "special" tools, going to call them as well.
Best video so far
Excellent video! Thank you!
Thanks for watching. We're glad you liked it. 1aauto.com 866-403-3393
@changellv Thanks for watching.
I'm missing a protective plate in front of my A/C belt in my 2007 1500 classic. Should there be a plate guard in front of the belt area?

Yessir because I’m without ac in this Texas heat but I don’t want to spend over 200 for some one to fix it
More pictures of the GTO please
Great videos! Thanks.
Hey hello I got a problem on my 03 chevy Silverado 1500 v8 the ac is kinda cold when I'm running on the highway but when I reach a red light or I stop on idle it turns real hot , I changed the ac clutch nothing seem to happen I recharge the system nothing same, I cleaned the condenser for any bugs and same thing you think it's the ac compressor ?? I have it on idle and the ac compressor kicks in and out the freon was good but idk any more what to do
Outside ambient air temperature sensor on my 2002 escalade was bad causing this issue
GREAT VIDEO!!!! VERY HELPFUL!!!! THANK YOU VERY MUCH!!!!!!
You may want to have the Freon level checked to see if it needs to be charged. 1aauto.com 888-844-3393
does 1Aauto sell the engine shields? I'm missing mine and the dealer thinks they come standard
Would this be the same for a 2004 trailblazer 5.3?
What is the part number to the AC belt? I do not see it in the links. Thank you.
what about the belt squeal? i tried putting another belt on 1/2" smaller but it wouldn't go even with tensioner loosened all the way. the first tensioner i put on to replace the factory tensioner broke so this is the 3rd tensioner on it. the slipping only happens while the compressor is engaged and it has a new dayco belt and tensioner, i've tried belt conditioner and even cleaned the pulleys with paint thinner to ensure there's no build up on it. would you say i need to replace the a/c clutch?
How many amps do you recommend for that type of trucks alternator
i'm pretty sure my AC compressor is slowly dying. it's making a sporadic whine and grinding noise. will any harm be done to the engine if i remove the belt until i get it fixed?
Hi very good videos thanks!!!! I have a question for you, I have a 02 chevy Tahoe 4.8 2WD. When I turn my a/c on, it feels like its going to turn off, also today my ac was on and as soonest i accelerated it started squeaking very load, I turn off the ac and it was fine again. Is this the ac compressor going bad? And if it is whats the repair cost on this I know is just a rough estimate but would like to know how much money Im going to spend! thank you in advance!!!
Will the ac belt affect warm air from blowing?
+Junior Chavez We wouldn't be able to diagnose an issue like that here, you may want to have a local mechanic take a look at it. Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c
After I changed my ac belt my truck started making a noise in the cabin , what should I do to fix any suggestions ? It was the ac belt ..
i have such a hard time putting the belt over the AC pully. Is there a trick to get it to stretch over it?
If you pull the belt tensioner down far like we show in the video you should be able to slip it over the AC pulley. If any of our viewers need to replace their serpentine belt, we carry the one shown in this video on our website. Here's a link to them.

Will the ac belt cause my truck to overheat?
Nice 66 GTO drop top!!
Never mind thought you were replacing the compressor that's what I'm looking for
We currently do not have an auto repair video that covers this particular repair. We will keep this request in mind in the event that we need to make this repair in the future. 1aauto.com +Dustin Towsend
Why does every video on the a/c belt give the number for the serpentine belt but not the actual a/c compressor belt?
I had similar problem, freon was at proper levels.
Why does my 2004 2500 HD keep throwing compressor belt?
You don't need air conditioning can you eliminate this belt?
Turn the AC on and see how the AC clutch reacts, see if it shuts off when you loose the cold air. If it does, check the AC relays and the power to the system. Hope this helps you out. 1aauto.com 888-844-3393

Should have took air box off gives lil more room but great video

Awesome video Mike keep them coming .thanks John
I have replace my Compressor belt twice and it keeps burning up why? thank you.
I replaced my belt and it only lasted about 3 months. It kept making a whiny sound whenever I turn the ac on but it would eventually stop, then all the sudden the belt broke and its just hanging on the pulley. Is there something else I need to do? Please Help!
I really appreciate it helped me out today with my 2001 Yukon Denali

i just replaced my belt and as soon started my truck the belt just smoked and broke..i know i put it on right checked millions of times...also non ribbed side of belt was worn down
Can you drive without ac compressor and AC belt?
Yes definitely
It’s not always as easy as it looks. Maybe the parts store sold me a belt 1 inch shorter than the original. As the old belt snapped and flew, I have nothing to compare. Screwdriver and pry the new one on while holding the idler pulley is not an easy task
perfect
You may want to inspect the belt to see if it was coming into contact with something that may have frayed it. 1aauto.com 888-844-3393
