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

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

Hello, l wonder if you could help me out with a doubt that I have, it is about the AC system, here it goes, I am changing my condenser In a Ford escape 2008 v6, because it has a leak in both system, in the AC lines and the transfer lines, so, it has no already ac gas because of the leak, if a replace the condenser, do I need to add some oil gas compresor? Or I can after I finished it installed take the escape to the shop to refill the ac gas? Thanks for the advanced.

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.

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 06 Elantra make the same noise! My alternator bolt was loosed somehow, but it was tightened and the noise had returned (only when turning left. your thoughts? I looked at the pulleys while the wheel was turned left and 1 of the pulleys almost stopped then the noise started. any advice anyone?

Thanks, this is what i needed to fix mine, should have known after removing the pulley.
- don't worry about the talking to yourself, i tell my wife it is because the Three of us get a lot more done if we talk - She says Three of you? I said yup, Me Myself & I - all three of us!

Awesome video! I've had a squeaky belt from pulling misalignment since I bought my Dodge ram 2500 truck. I've already replaced my tensioner, alternator, idler pulley and your video reinforced my thought of the power steering pump. I have suspicions that I may be coming from!

Gates belts used to suck for import applications back in the 80s-90s. Wed use nothing but Bando from WorldPac. Thats all changed in the last few years. Gates import belts are quite good now. Many Asian imports are coming from the factory with Gates belts.

Ive got an ls1 with a gilmore drive kit installed and im getting constant vibration from the adjustable tensioner pulley bracket, any ideas what could be causing this thanks

Thought I had a bad tensioner, belt made noise, etc. Found a bent shaft on alt. Check everything on older cars, theyre likely to have been wrecked at some point

This guy's diagnostic skills are supernatural. I could see an 80-year old guy knowing all this, but Eric O. ain't that old, fer cryin' out loud. He's GOOD.
