Once again I team up with BBB Industries to bring you this video on what to look for with your belts and pulleys. So if you have a noisy belt you might want to perform some of these checks first as it may not be the belts fault.

This guy got me into auto repair! I've so much to be grateful for. His repair videos are flawless - honest, solid advice from a seasoned professional. Huge respect to ETCG!

Auto repair seems really boring and very very hard
dude I just love how thorough you explain things with many major important detail that no one would ever point out
Eric The Car Guy is awsome!!! He explains things that a stright-up dumb-ass can understand!! Thanks Eric!! Keep up the videos. they are very helpful. Even to mechanics who can't figure something out
@trekzilladmc I normally leave those alone but if it gets worse replace the tensioner, the point of the video is more to consider the belt and tensioner if you have a problem with one of the accessories like an alternator or power steering pump problem.
Thank you Eric , I appreciate your explanation of all the projects you do. This video and others you have done have actually helped me problem solve a few issues I’ve had with my own car.
@videomotion8 Depends on the engine, with some it's just the back of the crank pulley with others there is a small disc that needs to be installed to help guide it on it's path. It's usually at the crankshaft from what I've seen.
Thank you for this informative video. I had a tapping sound issue from my Ford 2V 4.6 engine and I was scared it could be a costly timing chain problem . Today I found that the belt tensioner pulley bearings were worn out and was the cause of the tapping noise I was hearing. It makes sense now that you pointed out the mal-effect travels all over the related components (as did the tapping sound+vibration), it was very hard to nail the problem for me. Problem is, these parts are hard to come by in my country so I have remedied temporarily with some silicon grease spray to the bearings. It did make the sound go away, so hopefully I could get the parts from good ol' USA in time. Thank you once again!
Thanks eric you have literally walked me through several problems ive had. Keep on keepin on brotha especially on the great work.
Really wish you worked in my town- you seem honest and knowledgeable. Thanks for the video. Hope it helps my shade tree guy.
@1ownjoo2 After a while the rubber wears out and will not be as effective, glad it worked out for you though thanks for the comment.
eric thanks for taking the time to post these videos i started watching when i bought my first car with your help and no previous experience i have changed ball joints brakes belts pcv valves and do my own oil changes i am now enroling myself in an auto tech class thanks for the knowledge and saved money !
@aeligos It could be loose but it could also be a bearing somewhere, if you feel you have it as tight as you should make it you might want to check the rotating components for a bearing issue.
I just noticed my pulley completely snapped off! Thanks for the video, this is my first time working on this area of my bronco and you have helped me so much!
@DKLGalactus5 I'm glad you stopped by, good luck on your ASE's.
Always love your videos. I've been dealing with this issue for years on all of my vehicles. Hearing the constant chirp is a thing of the past after I watched your video. :). Keep up the good work, E!
I would like to thank you, you have helped me repeatedly over the years with working on my vehicles due to economic necessity.
Really great write up. I appreciate your thoroughness; I've worked on cars and trucks for years and still learned many things from this tutorial
thanks, you are often very detailed in your explanations. thanks so much for the warnings, about how a belt pulley or tensioner might lead to symptoms like the alternator not charging properly.
@moni370 You might check the belt for wear and the tensioner for proper operation. I'm not a Saturn expert but I think they have both belts and chains depending on the make and model.
@XHikotheproX Welcome aboard and thanks very much for your comment I really appreciate it from one 'car guy' to another.
@aeligos Anytime metal parts rub together it can cause a squeal, it's worth looking into.
Last video I’ll ever need to watch for any serpertine belt or pulley issues. Thank you Eric!
Your the best! With your video i discovered a worn idler pulley. Replaced it and the engine compartment sounds happier.
Keep up the great work!!
So glad I came across this a few days ago. My drive belt on my Ram went out last night when I was far from home. I knew exactly what to look for, and had it fixed within the hour. I had been hearing a sound like bad bearings for a couple months now, but I procrastinate a lot so it never got attention. Thank you.
I just discovered your videos and have to say they are fantastic. Not only your knowledge about everything but your intuition into what questions might arise in the mind of someone watching and addressing them right away, concepts and all. Thankyou for making these videos and keep up the great work.
@dandim23 You need to verify that it actually does have high voltage either with a DVOM or a scan tool, if you find that it does then you might consider replacing it. However it could mean that there is a problem with the cat or some other fuel or exhaust system problem that's why it's important to check it out first.
Doctor Eric the Car Guy I'm so glad you posted this video and my Pontiac Grand Prix 04' is too.
Very helpful video, I just had my drive belt replaced today and thus helped explain everything. Thanks Eric!
@Bbyslim87 You can remove the belt and start the engine to listen for the noise, if it's still there then it could have something to do with the timing belt area, if not you can rotate the pulleys by hand to see if you can hear or 'feel' the noise otherwise you may need to use the methods I show in my Finding A Noise video. Good luck.
Thank you for the information. Recently had thermostat replaced and a two day later a revving noise started happening and noticed a tug on acceleration with knock sensor malfunction code. Watching your video I'm going to inspect tensioner and belt.
@PVoyager Personally I would go with OE or a quality aftermarket part. Try to stay away from parts that come in unmarked white boxes is probably the best advice I can give.
Hello Eric the car guy, thank goodness there are good guys like you out there helping automobile engine challenged persons like myself understand the workings of our autos. Now when I visit my mechanic to check out my squealing belt issue, I will have a much better understanding of possible problems. Thank you so much. You are a bright light out in this big wide world. Please continue your great work.
Right. I had basically exactly that problem with the alternator not charging the battery (and some of those check engine codes popped up upon checking). Took it down to the shop and it was (at the core of it all) the pulley, but the belt was pretty well shot too because I didn't think too much of it when a classmate mentioned that maybe I should get the belt checked a few months before yesterday.
Things that might happen when buying a new-ish (cheaply) rebuilt car.
Im going to school to be a diesel mechanic at Unoh and i just found your channel today and you are better at explaining certain subjects better than my professors. good work sir.
God bless you Eric. These videos help countless people!
Amen to that Andrew 👌
At least 1.1 million lol
@Warlord1264 I'm not clear on if you replaced the tensioner or not but if you have then perhaps there is some stuff in the grooves of one of the pulleys or something that is causing the belt to bounce around, old belts can also cause this so if you haven't replaced it yet it might be a good idea.
Very helpful video! I have a Saab 9-5 and noticed the tensioner was bobbing slightly even at idle, also another pulley seems a bit worn out, may well be the drive pulley and this video has literally very well clarified this fault for me. thanks Eric :)
@branco445 Sometimes the covers don't get installed correctly and can come into contact with the moving parts causing a problem like that. Good luck.
Great delivery Eric. Like how you lay things out.
@TearsOfTheCloud Thank you very much for that. Things have been growing pretty steady over the past couple of years so we'll see what that brings in the future. Thanks again for the comment.
Mines has a pulley,or tensioner,not sure which one,the one you said was Rock solid,it's wobbley,and...my code is showing a transmission problem,but,I don't know if that can be related,I hope so,unless I do need a new transmission...not only does that wobble,but,fan also looks like it's shaky,though I had it replaced not to long ago
@Nikon89xj89 It's not likely to be the crank pulley but you might consider taking the belt off and spinning the components individually to see if you can find the one that's making the noise. Good luck.
Eric ROCKS!! I believe I can even change the serpentine belt on my motorhome with his help. Thanks Eric!!
Great informative and well done. I am a baseball coach and spend all my time fixing players. When the cars go bad and I cannot get to the field I cannot do my job. So i appreciate this segment on belts. Now I can go fix it and get back to the game.
Frank Fulton GM VMarlins
Great job done Eric, Thanks for all that easily understanding knowledge given!!!
think you just diagnosed my problem in the first min in a half. I have noticed one of the pulleys near my alternator wobble a bit a times and i think thats why it isnt producing a good charge to my battery which may be why my car randomly shuts off at times. When idle lile at a stop light. This car shop adjusted my belts awhile back so hopefully when i take it back to them its a simple adjustment fix. Awesome advice!!
Thank you Eric for the video my tensioner pulley just started clanking and clunking I narrowed the noise down to my tensioner pulley it looks like the spring in it is worn out
Just when I thought I'd watched all your UA-cam videos!!!! Glad to see there is still something to watch!!!
Thank you. I'm having squeaking issue with my 2008 M45 and I'll have to look at those pulleys and belt. Just as you said it could be the reason I have a check engine light that goes on and off.
Eric. Thank you for everything. Your service is phenomenal.
I love your videos.! A lot of help. I was having a trouble with my tensioner pulley, replaced it and it was great. Now that noise came back again and mostly when I hit about 2K RPM.
Wow! That is excellent information Eric. I am just going to change my drive belt on my 2006 Buick Allure and that info explains a lot and what to check for. Thanks!!
Thanks, Eric I think I solved lots of problems watched many of your shows.
Excellent video, great info. Thanks. My 02 Tundra is configured different from what I found on youtube. However, this elementary explanation provides the knowledge for any configuration. Eric the Car guy gets an A++
Thanks Eric,
Your video answered a few of my questions in relation to excessive noise from my engine compartment. Now I know that main pulley and tensioner on my 2005 Mazda Tribute need a fix as both components vibrate when engine is running. Thanks again, now at least I know what to discuss with mechanic when I visit a workshop.
I'm about to replace alternator....this was a helpful snack for thought.... thanks....will check on the belt and the pulleys and tensioners.
@skoalchurch You could isolate it by removing the belts one at a time and seeing if the noise is still there but by the sound of it the AC belt might be the culprit, I might check the tension on that one and go from there.
If I pull one I'll pull 'em all.. 1 time.. like Jesus being crucified.. once for all. Peace.
wow. i have a check engine light on and the code is for misfire in bank 1. i also have a squeaking belt....eric, u r THE man
🙋🏻♂️ same and now im fix it thanks to Eric
@aeligos I'm happy to help, good luck with the work.
@TheDvayers Thank you very much for that comment as that is EXACTLY what I try to do when I make the videos, it's nice to know I'm doing my job well. Thanks again.
@dendorssers I might be able to pull that out of the Accord timing belt video. Thanks for the suggestion.
Pls why belt pullouts on pulley in few seconds
Eric you were completely right!! my steering pump was making noise for a long time and when it came time to change the belts i watched this video before and now with new belts my pump is silent
Excellent, thanks man. And I will be sure to check pulleys with the engine on as you stated, thanks.
@dendorssers I will say that not all belts are created equal but also it could have been a tensioner or idler that was making the noise as they often act that way.
Dude awesome information, very helpful. I do as much of my own work as I can and I just bought an Isuzu rodeo with an idle tic now I think I may be able to figure out what it is and why that check engine light is on without taking it to a shop, fingers crossed.
@BriggsMower Hard to say, if you know the belt is new and isn't glazed and that all the pulleys are good then perhaps there is an accessory that's having an issue like a power steering pump or AC compressor, it's worth checking out anyway. Good luck.
Sometimes maybe the belt is put on too tight. .
Eric - Thanks so much for posting this - I'm working on a 06 Avalon and my code scanner is showing inadequate charging from the alt - no belt noise but, I believe the tensioner is orig with about 100k on it. Will do a belt/pulley inspection under power next to make sure things are ok to rule that piece out. Really like your channel.
@aeligos Perhaps the tensioner is faulty then for not maintaining the correct tension on the belt.
I learned a lot from your videos, great job on explaining these things and potential problems if not fixed/prevented.
Just getting ready to replace my tensioner pulley on 96 1UZFE 4.0L Lexus
I found out that 27 pounds of tork is needed when putting bolt for pulley in place. Does that sound right?
Also, does that bolt tighten itself?
Do you have a video on checking alignment in the serpentine belt?
Thank you
I appreciate the thorough and thoughtful explanation.
I just found your channel a few days ago, and im a car guy myself. But i have to say after watching some of our videos ive learned a lot of useful tips, thanks Eric!
i love eric's lectures!!! so informative!!
Hi ETCG, I definitely appreciate your time and information that you give through your videos. I ended up with hearing like a light pop, more like if you drove over a cardboard cylinder and right after my steering wheel became stiff. I'm thinking power steering fluid but I open the hood and noticed the belt loosen, basically off. Thanks to your informative videos I knew what was the problem. I just don't understand, there was no squeaking or trouble with anything else.
Omg this is exactly what happened to me yesterday after I'd hit a pothole, that I was trying to avoid lol! Battery light came on, steering became stiff. Car started to shut off after a short while after starting. I was about to go get an alternator. So glad I watched this video and read your comment..
@Thegarmendia I've noticed that too, thanks for the comment.
Oh Eric, u always explain everything really good.
Eric, I understand this is an older video but I have also been watching your newer videos, and your cameo appearances on TRQ. Welcome back! It would be great watching you perform car reviews for new Honda much like the car care nut channel. Would also love to get an idea of what’s happening in your world and if you’ve given up on UA-cam. You have a lot of great content and thank you for all the information over the years. The community needs a tech experts opinion on Hondas to give them advice for new vehicles.
As always Eric, an informative and entertaining video. Spotted a dodgy tensioner pulley thanks to this. 👍👍👍👍👍
@MileyCyrus192 It's nice when it's easy to find an issue like that, thanks for the comment.
@cesear123456 On this one all you need is a 3/8" ratchet. See the replacing a serpentine belt video for details.
This is THE BEST video I've ever seen on how a car works and what this "supposedly important belt" does on a car! My God I think I understand it know. My AC hasn't been working well, then the steering got difficult and then this terrible squeaking started.This video explains how the belt is connected to all the components and how "the energy is transferred" from the engine. This guy is a real good explainer. Thanks ErictheCarGuy!!! :)!!! :D!!!
Erick this video really helped me today! Thank you!
I do have a question about my engine...do you think I can post a quick link for my engine's video here for you to help me please with it?
Every time I start my car it gets really loud, as if I was pressing the accelerator.
Thank you!👍 You're the man!
Informed by EricTheCarGuy. Thanks for the helpful tips. Now subscribed to your channel.
I been havin a loud growing noise after lookin at da tension closely i see it bouncing around.than u mentioned it b4 i watched da video thanx 4 da video it helped me pin point da issue
@aseglkj Glad you liked it, thanks for your comment.
Dude you are alright in my book. Party on with all the fixes
I've watched all of your videos their great resource. My question is on a lexus rx 300 v6 3.0 power steering pulley way offline of the crank shaft. I just finished the water pump and timing belt yesterday but noticed today that power stering belt is about 5+degrees off from the crank shaft pulley. Its now rubbing on timing cover behind the crank. What and where should i start with this issue.? Thank bro
It is only four guys on youtube that i subscribe to for help with my vehicles and Eric The Car Guy is deffinately the #1 when i am doing research.....Keep up the good work Eric you don't know how much we really appreciate your tutorials......
You always make the most accessible and comprehensive videos. Thank you! I am a random 30/F who has gone from zero car knowledge to being able to do light work on my Wrangler, largely because of you. I'm still a hack, but at least I can put up a front when I end up taking my car to a legit mechanic (I'm sure they can tell). Thanks!
Hello I am wanting to know what to replace on my Nissan. My belt melted on the bottom. When I start ted the car I heard something sounding like a fan cracking up . And seen a piece of black circle like kind of chipped up. The car was smoking a little on the passenger right front. I started the car again and the belt was a bit side ways but not moving. Can you tell me what I should do when I go get the serpentine belt replaced
Help
great advice.... I know I pick out stuff from your other vids but this one is good !
Nice thorough video. It helped with changing drive belt on 97' mercury mystique. Runs better now with no squeel. only makes a little noise when the air conditioning is on, pulleys seemed ok, but I suspect the tensioner pulley to be acting just a little bit silly. I can go without ac, just put down the windows and sweat it out
Wow, that was a great video and you, Eric the Car Guy, are a fantastic teacher. If you don't teach courses currently, you should. I've never been a car guy but do like to learn new things. I gotta tell ya, after watching your video and listening to how you describe things in your "lessons," I'm intrigued to learn more about automotive repair. Maybe a new year's resolution for me - become an amateur mechanic?!?!
Great video as always. Any advice on adjusting the power steering pulley alignment on a 2007 Escalade? (6.2L, AWD). It's a few mm out of plane with the rest of the pulleys and tensioner, and the serpentine belt occasionally walks off the crank by a rib.
hey eric, that video was really informative. although Im having a really bad sliping belt noise inside the engine bay everytime i slow down when the car is already in operating temp. it will only stop squeaking if the car gets in a completely stop position. i just replaced all my drive belts as well as my timing belt on my 1992 Nissan Pathfinder 3L v6. I replaced my drive belts because it started making a sliping noise. the noise stopped for a week or so after replacing the belts but came back after that. I tried tightening all the belts again and it still does it, how could i know if its a bad pulley/bearing/or pump? the Pathfinder will be off road this week and I dont want any belts or pump be seized while off road. thanks in advance :)
@vinceperez158 I might think about changing it before there is a problem.
So my tensioner shakes when the car is idling. I guess I need to replace it right? By the way I had to watch around 10 videos until I found yours to get the info that I needed. Thank you very much! 👍
Hey I'm having a hard time locating a tensioner and pulley for my 1994 caprice ls 5.7 liter. Do you have any idea where I can buy one, because I've been looking even asked the dealer.
@shoeb2015 I try to make videos that I think would be helpful if I was watching them, I'm glad that philosophy is actually working. Thanks for the comment.
Thanks Eric I noticed that my belt tensioner is kind of bouncing up and down and I wasn't sure if that was normal or not.
Eric - I have a 2004 Toyota Tundra V8 (175,00 miles). My serpentine belt snapped and my alternator pulley does not freely spin. The alternator is the original and the belt was about 5 years old. I was not having any issues before the belt snapped such as chirping/squeaky noises, dimming lights or "check battery/engine" lights. Do you recommend a pulley replacement or a complete alternator replacement? Thank you...I appreciate any advice!
Eric is my favorite! I say that like a 12 yr old haha but seriously learn much from you. If you do more TL vids, I'll watch them! Thanks man
@RradioActiV83 Any of the name brands are good, I really haven't found a brand that was a problem up to this point. The important thing to take away from this is to also check the tensioner and pulleys, if the tensioner isn't good then a new belt won't be of much help.
Excellent videos as always. Thx.
