- Let's grab a laser beam and fix that squeaking belt! SAY WHAT!? In this video we use a laser pulley alignment tool to identify a misaligned pulley on this GMC 6.0 that is causing one nasty belt squeal. One of the most over looked items when folks are trying to diagnose a belt squeal is pulley alignment. As you will see in this video, it doesn't take much. -Enjoy!

"That belt is so quiet, you can hear the leaky exhaust manifolds now." 😂😂😂😂
This guy is legit. He knows everything! I went to school for automotive & diesel technology 17 yrs ago, and although I never pursued it as a career I am constantly fixing vehicles for friends, family, and neighbors. I often find myself chasing my tail with certain issues and this would have been one of them! I would have changed the idler, tensioner, and belt....cursed up a storm when it was still squealing, then proceed to change the harmonic balancer, and drive accessories one by one just to suffer a brain aneurysm and possibly a heart attack simultaneously when non of that would have worked! Great job MR. O!
smart. cleaning the grooves is often overlooked.
Belt alignment and laser eye surgery... all at the same time! :D
lasik by SMA
Belt so quiet you could hear the leaking manifold gaskets 😂😂😂
This was one of the best videos. Never even knew the depth of some of those pullys is adjustable.
Thank you, thank you, thank you for this video! It saved me from going crazy trying to find the source of the squeak on my sons dodge pickup. We did just as you instructed and now no noise!
I could understand the first time around when the first shop got it. But when the vehicle came to the second shop, I'm sure the owner would mention to them about this issue had reappeared. Glad to see you got it fixed once and for all!
Nice job Dr Evil. Hope you and your family have a safe and happy new year!!
Great video. A coworker when I worked at a shop briefly gave me a Dayco kit. It may have even been to get it out of his toolbox and free up room but regardless I’m finally seeing an opportunity for it 1.5 years later. I wouldn’t buy it new myself in any relatively soon time if that $100 price I saw somewhere is current, so it’s great to have for free.
I love you so much!!! You saved my life again. Thank you for being so thorough. You are the best mechanic ever!!!!!!
Love the video, my son had a Jeep Wrangler that was eating one rib off the belt. Took me about 4hours to finally find the problem. The rubber on the crankshaft went bad and caused the pulley to move ever so slightly. Finally found the problem when I could just see a little bit of shinny metal on the crankshaft telling me it moved. Put on new crankshaft pulley and fixed the problem.
My '97 k1500 with a 5.7 was doing this, I took it to a shop and they couldn't figure it out. That didn't stop them from charging me. Gave me dirty looks when I came back.
Watched this video and checked the power steering pulley, it was in too far by one quarter inch. Got it set in the right place as you describe and haven't heard a single squeak since. Thanks Eric O!
That's a pretty cool tool. I never knew they existed. I have found that most pulleys either go on flush with the end of the shaft, or down to the edge of the bevel on the shaft. I always just make sure to look at the placement before I take it off, and so far haven't had any issues.
that was squeeling like ned beatty on a canoe trip lol
i hear banjo music !!!
Gross.
richard cranium so this makes Eric, Burt Reynolds with his bow!
richard cranium Ned Beaty had the hardest part.
Bahahahaaaaa 😂
We have been using Goodyear now Continental Elite belts and hose products for about fifteen years and our noise problems went away been real happy obviously this truck had a different problem but those belts fixed complaints that dayco and gates used to cause.
Thanks for the education Eric
I have done at least 500 of those...lol..Worked for years at a HI/lo(Auto Parts) in Houston and never once did it with Wrenches ...Always pulled and installed with an Impact ....We had a Special tool for Pulling but for installing we used the kit that came with the Pump ( Threaded bolt...flat washer...square Nut).☺ Kudos Mr O!!!
Just want to say your analysis of the source of the problem, and how to correct it was superb...My vehicle is no longer shredding serpentine belts! Problem was power steering pulley was 1/8" from flush.'
Great job Mr. O! Thank you for your great videos. Your wealth of knowledge is appreciated! Keep up the great work.
You Da Man...as always all the other mechanics could not find the issue...way to go Eric O.
You should try trying to retime a Chevy 396 with one of those harmonic balancers that slipped
Had to change one for my father-in-law
Great video on pulley alignment and thanks for showing us how to use the lazer pulley alignment tool. The only problem with that tool is that the magnet sometimes doesn’t hold the tool onto the pulley that well and other pullers or things can block the lazer beam from reaching your target.
super helpful. I have had a chirp for a while since I changed my ps pump. I noticed the belt was at the back of the idler. I sucked the alternator forward but it wasnt enough. I will check my ps pump pulley this weekend. thanks.
Thank you so much for your tutorial, my chevy astro had the same problem, I
re adjusted the power steering pump pulley and the noise disappeared. You are the best, best wishes for you from Las Vegas, NV. Take care man.
Learned something new , did not know that pulleys can be aligned manually like you did thanks
Eric, back in the mid 80's the first gen front wheel drive Buick park aves and century's with the 3.8 v6 had this same problem, fairly extensive. Back then we took a long extension and while the engine was running, we'd push on the side of the belt at various places etc. and see how that made it worse or lessened the sound and figured out where the problem was. In the case of the v6 there was a TSB on it and the fix was to shim the harmonic balancer out, and that fixed the problem.
Nice way to end the year with a SMA video.
actual pulley misalignment amazing! I've mostly found chinesium plastic, aluminum or steel pulleys worn down from fluid leakage and grit eating them. of course no amount of cleaning or belt type fixes that issue, new pulleys all the around.
Excellent info there Eric, I didn't now these types of laser alignment tools were out there.
I remember the older tbi/tpi had the exact same issue. Good times dealing with rust and stripped out pump threads....
Well played Mate! Your diagnosis and solution was spot on. Nice to see a quiet lorry back on the road..................the poor bloke who had to listen to that will be your friend forever! He should shower you in quid for that service!
You learn something new everyday.
Just fought this problem this summer. Found after changing power steering pump. My pulley wasn't in all the way. 97 Chevy. Same style set up
Great Video Eric I probably should buy one of them as Pulley misalignment is more common than one would think but usually it's cause is a pulley failure or water pump coming apart causing the misalignment
Gotta say, that was very interesting as it's not seen often. Well done Dr. O and thanks!
Well done professor O
great video and for you Eric and your family a happy new year
Nice shout to Leon! RIGHT.....SORTED!!!
Always learn something new here, thanks, Eric.
Great testing diagnostic theory with tool laser beams and pulley alignment
Nice job Eric O
Great Repair, never used a laser before Thanks MR O
I just went through this exact issue on my 5.3L after replacing alt, tensioner, idler, a/c tensioner ( which is unrelated) and power steering pump but I had no laser tool! Ugh man! Initially all the work I did was fine no probs. But then it started raining for days at a time and outside temp dropped down to the 30's and 40's and it started squeeling and bad. 2 dayco belts later, one of which kept walking forward on the crank pulley by a rib which I couldn't figure out for a couple days, repeated adjustments and a lot of cussing I got it right, but once I got it correct with the dayco belt, I put on a Goodyear Gator belt instead to seal the deal. Everything has been perfect since then and it's been staying that way even under heavy work load and repeated full throttling on the freeway etc... I didn't know there was a laser tool, I know now though ughh! Oh well... Thanks for the video I appreciate it.
Nice job
Back in my day we just used a piece of floss, some squinting and a yard stick, close enough, never had a squealer.
That laser is a bit more definite though.
oh happy new year Eric all the best to you and yours.
Hey Eric, talking to yourself is healthy. Arguing with yourself could be an issue and losing the argument, well, I don't want to think about it. Happy New Year to you and your family. Thanks for all the great teachings and videos.
Alain Lemire Actually I think arguing with yourself is ok. I draw the line at beating yourself up and knocking yourself unconscious - that's when you're definitely coo-coo!!
Had a squealing issue on my 4.3,changed belt,tensioner etc to no avail. Turned out to be the power steering pump bearing was worn so it was throwing the belt out of line..A new pump fixed it,but I was amazed that with that much wear the pump was not leaking.Had it been it would have been obvious that was the problem.No laser,but a straightedge works well also
Happy new year!
I thank you so much for all the info, There is a lot of this problem,
Happy new year to you and yours
Limited space.
Great job and effort, man!
Good vid again.. Have to admit when I first tuned in, there was a real Red Green feel to the way Eric produces his video's . (Without the duct tape, but with a Laser) LOL....Good stuff as always!!! I do pick up good info every video.. Thanks for sharing, and the info always gets you pointed in the right direction..
Well done . Lesson learned, thanks!!
Happy New Year to you and your family!
Thanks for the tip, worked very well for me 😊
Looked like a perfect opportunity for the "Good Stuff" cleaning out the pulleys.
You working with that pulley puller was crackin me up!
Like that tool
these were in a bulletin throu GM for the repair done 100s of them!
WOAH! You just shined that laser beam right in my eye! I want my money back. If you looked close at the belt coming around that pump pulley you could see it was leaving the pulley at a slight angle heading up to the alternator. Glad you got that all sorted. Happy new year.
Next you'll be wanting your money back for the bad air.
happy new year from Australia !
Hope your feeling better today!
Didnt even know that miss aligned belts was a thing. Thx for the vid.
I hate it when I misalign my pulley! Nice video Eric.
Great Work , In the HVAC field we use string .
DP T
Cats like string too lol
Thank you, this video helped me diagnose my engine bay squeal (alternator belt pulley alignment.) Didn't help me fix mine, though. But I finally know what the problem is: And that's been my problem all along (not knowing or being able to diagnose the source of the noise.)
Mine rotated from tensioning it over the years. The method to tension it is to leverage a crowbar against the alternator, but it has gradually caused a very slight twisting of the mount over time (1-2 degrees maybe, it's visible but only barely.) Trying to think of how I can fix this without breaking anything lol.
Great video, valuable info. Ive never had a Dayco belt that didnt squeak no matter what vehicle. On my old 2003 S-10 ive had excellent luck with Goodyear Gatorback belts, never a peep of noise and I get excellent service life. No parts stores around here carries them, have to go online. Eric your videos ROCK-!
Another awesome video from SMA.This is the sixth one in a row I've watched tonight and only on my 2nd Inducer Rebuild I guess I'm doing more watching then working. Oh well I know one thing I'm going to get me another SMA shirt!!
This turned out to be my problem. The guy I bought the car from had straight-edged the pulleys but the grooves were still out of alignment. Belt squeeled like a banshee. I pushed the pulley in to match the shaft and problem solved. Thanks South Main Auto Repair
A+ today on repair
Anybody ever bought a new tool and scuffed/ dirtied the case to age it so if your wife asks, you can say "oh, this? Ive had this for a while...." 😀😂
dave1135 lol I am sure almost every guy does that
Mostly with weapons and holsters. Seems I acquire plenty of the accessories. Lights lasers e.c.t. But tools no problem for me.
Nah. I just told my ex-wife that if she didn't like her husband buying tools then she should have married an accountant. Anyway, that didn't stop her from bitching, so I got tired of her bitching and bailed out.
Hey, quit giving away our secrets!
Tools , hunting gear , fishing gear , you name it , guilty as charged !
Thanks for sharing. Very cool and useful tool. I could see from the camera angle that the pulley was not aligned correctly.
Thank you very much 👍
that video of the bald Eagle was fantastic. Better than Suzuki.
No beam, laser beam, no beam, laser beam.
Happy New Year! Eric O.
Good job Erik you explained the job very clear thank you .old Jimmy west Australia
Happy New Year, to you and yours, from me and mine!
My 04 Silverado is doing the same , recently changed power steering pump , going have to set the pump pully in more on the shaft , I'll do laser check since I have few lasers for checking scope alignment on my firearms . Only squeals when turning , so can't be off very much
I’m a Millwright in Canada and we do laser belt alignments often.
Happy New Year! Love your videos... keep em' comin' :)
Thanks man that helped me figure out why my belt is chirping sounds like it come from my alternator I will check the power steering pump pully.
Our parts store has carried Dayco belts and hoses as long as I can remember. I've installed a lot of both. No issue with them.
In 1986 we had a bulliten to install a .060 shim behind c/s balancer to get rid of belt squeal.
At 14:55 when Mr.O was spinning that P-Steering pulley you can see the lip of that pulley was sticking out past that washer that was on the Idler Puller after the adjustment at 21:45 you can see the lip on the P-Steering pulley is way in now. Good Job Mr.O
love the commentary.
A parts house gave me one of those a few years ago i think its pretty awesome
Sending you good vibes 🙏🤗
Man this was awesome and solved my mystery squeal. Thanks !!!
Squeakage🤔
I think that's a squeaky sausage
Squeakages! :D
Great video, very professional job. 👏
Great job, You got that SORTED..🤔👍
thanks for this Vid was able to fix my chevy squeaking THANK YOU
That’s all experience
Gotta live it
New Year's Eve Eric O in the morning doesn't get any better. Even though Eric doesn't like Dayco belts if other viewers are like me I always at least look at tools Dr. O uses and I'm starting to use his sayings, but at least I can use them in mixed company.
I changed everything on my 2000 GMC Sierra 5,3L 4WD but the squeaky rattle would not go away. Its because of The Autozone Duralast belt was my culprit . A Continental Elite , like a Goodyear gatorback fixed it look for a 6PK2340, but I was able to mount a 6PK2335 size which is 5mm shorter. Quiet is nice. Spray water on your belt. If the noise goes away temporarily, you need one of these belts.
Thanks for the video.
Happy new year !!!
Fantastic, happy new year
The "Alternator appears to have been replaced": yeah ..... I watched you replace it.
Right i thought the same thing!
Thank you very much 👍👍👍👍👍
