Tool Time: Squealing Belts, Laser Beams and Pulley Alignment, WHAT!?

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!

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!

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!

@texastoyz9341 4 жыл бұрын

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.

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.

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.

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.

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.

As soon as i saw the title of this video i thought i knew my problem. My tendioner pulley and s belt were replaced less than 2 years ago aling with timing and any other belts and its been squeeking and squeeling ever since! The tensioner came off yesterday and threw the belt. Guy said the tensioner is stripped. Now im a girl, not very mechanically inclined but gifted with a little common sense. (Still...i didn't investigate the squeeking i just kept saying "its all new belts it shouldnt be squeeking like that"! Its not a river in egypt) But Im thinking now, a misaligned tensioner pulley would cause it to become stripped over a period of time. I could be wrong but im about to find out. Hope i dont have to go buy a laser thingy. 🙄 Thank you so much for this very informative and watc hable video!

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.

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

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.

I bought a 1989 Ford van that had a belt squeal problem. The dealer sprayed it with lithium grease to stop the squeal. After 4 belts in 2,000 miles I took it to another dealer and the tech came back to me, while the vehicle was out side the shop, with a simple yardstick in his hand and told me to look. One pulley was almost a half an inch off. Thank goodness we had a Lemon Law in our state.
