Diagnosing Belt Noise squeak or squeal on a Serpentine Belt
Vložit

- It can be tough to diagnose if belt squealing on a serpentine belt is from poor belt tension or a bad pulley or worn water pump. This is a simple method to isolate the problem so you don't waste money on unnecessary parts.

@@SchrodingersBox I'm having my squealing car towed in on Monday. A good way to vet a new mechanic. Can't wait to see what he tells me. According to your video, it's a belt issue. We'll see.
The liberal comment guarantees I'll never watch this jackass again.
Great video! I'm a retired engineer and my issue is not hearing high pitch squeals. The water spray is a good first test,most likely the belt. Thanx guys.👏🏽
Nice vid. Just wanted to point out a couple of quick points/tips:
1. Belts are usually not the root cause of noise. Of course they can be, but often people replace that first, a new belt is quiet, but a couple thousand miles later the squeal is back
2. Lots of cars these days use decoupling pulleys on their alternators, and they typically can fail after 70-100k miles. Very quick and easy check is to pop the pulley cap and check for red dust, or remove belt and see if it is hard to turn. If it needs replacement the pulley is half the cost of a new alternator and typically factory alternators are of much higher quality than $150 aftermarket ones. Save your original if it still works and just replace pulley.
3. If alternator is good usually its usually an idler or tensioner. If you've had the squeal a long time, odds are extra vibration/misalignment has put stress on these parts, if they have a lot of miles on them already (100k plus) you might want to replace all of them at this point. Idlers are cheap, tensioners are usually a little more.
Good points.
You can literally save thousands of dollars by listening to this guy! Thorough, professional and straight to the point without any advertising or promotional bullshit. Huge thumbs up to Schrodingers Box.
Thanks man!!!
This was the exact noise I experienced after I changed out my power steering pump. The pulley needed to go in a bit more. I was about to replace stuff till I watched this video. Can't thank you enough!!!
Thanks bro very informative
Me too. I was trying to find the exact noise I had and this is the sound.
Very informative and live the delivery and terminology of the host! Puts it in laymen's terms without dumbing anything down.
Excellent guide, saved me lots of time and money! Even though it seems like common sense I never stopped to do a simple alignment check before trying to diagnose a squeaking belt problem. Thanks so much, you rock!
We had the same issue on our '91 Ranger 4.0. We had replaced the tensioner and that helped a couple of years ago. We replaced the power steering pump today and the squealing was back. I went through various forums online and remember going through all of the same answers that were there last time. Some of the solutions seemed really unlikely and, frankly, a waste of time.
I found your video and liked your logical approach and trouble shooting. Following your suggestion, we checked the alignment of all the pulleys and noted the power steering pump pully was about 1/4 inch out. We used a pulley puller and adjusted the pulley forward until it seemed to be aligned and crossed our fingers as we started the Ranger and the horrible squealing was gone. The truck never sounded better. No belt conditioner, tensioners, expensive belt, or cheap ones.
Thank you for taking your time to do the videos. You helped me to look at a solution that I probably would not have found otherwise. Excellent!
@Paper, I agree with your assessment and I am confident that your squealing problem will disappear with tension. One other possible cause of this by the way is a small dripping of coolant on a pulley or belt when engine is at rest. The belt squeaks briefly upon startup but soon stops because while running the drip is no longer on the belt for whatever reason (fan blows it, whatever).
Very helpful video. Thanks. A couple of things to note based on my recent experience with it
-if there's a lot of crap on the tensioner, idler or other flat-surfaced pulley wheels, that could be the source of the squealing, too.
-if there is stuff on the flat surfaced pulley wheels, depending on what it is spraying water on them can cause the belt to slip off (as happened w/my old Dodge van).
Once the belt came off I shut 'er down, then cleaned the wheels and belt. Inspected the belt (AOK), then used soap, water and a cloth for it (no solvents that might degrade the belt and nothing abrasive that might cut or scratch it).
My old van had so many spots of dried grease, road tar, and God knows what else on the flat-surfaced pulley wheels (idler, tensioner, and water pump in my vehicle) I used an abrasive sponge, soap, windex, and ultimately gasoline and a small wire brush that allowed me to get in there and clean despite the small working space. Didn't quit until the wheels were smooth and dry to the touch
When the wheels and belt were smooth and clean I coaxed the belt back into place, minus looping over the tensioner. My van needed a metric wrench (15) to fit the tensioner. You might want to check that you HAVE the right size wrench in advance, especially if you're a "shade tree" mechanic, like me.
To work the tensioner at the same time as you finagle the belt into place you'll probably also want a cheater bar for extra leverage. I did. Otherwise it's tough to get enough leverage when leaning/laying across the engine to reach the belt at the tensioner. You may want to have the belt behind the tensioner wheel before you start, too (between the wheel and the engine), so that your wrench/lever isn't in the way when you want to slip the darned belt on.
Once cleaned and back on, I bumped the starter a couple of times to ensure the belt was seated properly, verified that, then fired 'er up. Most, but not all, of the squealing was gone. Just a chirrup or three.
One final tip - when I got out the squirt bottle to test the pulleys again, a very VERY light shot on the idler wheel (so I could hit near the flat side of the belt) caused the last little squeaks to go away. So another use for your method is to allow just enough slippage for the belt to seat and align itself!
I really like your video. No frills no nonsense, and you are so generous to share your real knowledge at this time and age, where you tell us what really is the problem. That's v generous of you. Thank you.
Yes sir....I never would have thought of that...this video deserves an award.......I sprayed my belt and it went away...so I bought some belt prolonged conditioner and it got me a few months so I could save some money and change my belt.....man......great tip thanks a million
I really didn't know that a bab water pump could make the squealing noise. I was worried that is was something else. The squealing didnt start until the water pump issue. Thank you sir.
I just wanted to thank you for creating and posting this video! I kept seeing videos of people putting soap on their belts to quiet them down but that just didn't seem right! I knew there could be a more serious issue at play and your video helped me pinpoint it! Loooove your approach and the info you provide! You rock!
Seeing this years later. Helped me from getting ripped off. Thank you from a mechanicaly inclined chick. Long time since I had to work on anythng. All under warranty. This was so helpful. Awesome video!
Thank you for your simple explanation! I didn't want to guess the problem only to find out that I fixed or replaced the wrong thing.
"Parallax" - good word. You are obviously an excellent engineer and problem solver. Great video!
Thanks for the insight, great vid. This kind of stuff is major "slippery slope" territory, people live in fear of problems like this. Lots of money can go missing if you're not careful.
Thanks for the great help and video!! Belt looked good but I figured that if I were going to adjust it I might as well replace the belt. Took it off and it was cracked all over the place. I could not see it in the engine compartment. New belt and tension took care. Now I have a happy wife! Life is good again
Sweet, thanks dude for the walk through. I have an '05 pacifica that just recently started screaming at me, once I figured out it was the belt I knew where to go and now I get to have fun fixing it. Thanks again! =D
Thank you!!! You rock for this video. So appreciate!

Dude, I must say enjoy watching your video; still, this time, I will be watching your videos in the future. Thank you for not doing a 5-minute introduction until you did what you had to show us and how to solve the problem

+Dead Mall Nana You're welcome!
Michael this well could be a tension problem- remember when the AC clutch engages a loose belt is more likely to slip.
Thank u for taking the time to answer questions and make videos. I'll let u know how it goes for me.

Got one from me to for that comment hahaha
Trey Chastain
Mattia Williams you dumbasses can't even define liberal
That's a nice explanation of an old school technique. It makes sense that if the sound is from lateral slipping of the belt, lubrication with water would improve it. And it also makes sense that inadequate tension from a failing tensioner would worsen with the lubrication of water spray.
Thank you! Very helpful. I found out my power steering return was leaking onto my belt and making it noisy.
I can’t believe how many people write telling you they tried the water test," but that it only worked for a minute, what should they do?
What where they watching when they wrote? Did they even have the volume on? &^%?
You told them, and you showed them… Come on people, stop being so stupid.

Applepiebetty Betty, you should see my video on diagnosing a battery that dies overnight. One of the most often asked questionsin the comments is "My battery dies overnight, how can I know if it's the battery or the alternator?".
There is no hope for us. None. Christ, look at the comment right above yours.
“More annoying than listening to a liberal” LOL. Earned a sub right there.
Dude! I'm 70 yr old woman, I can't wait to run out and check this tomorrow! In freezing weather, I'd hear a squeal, always needed a jump. Got a new battery, and water pump. Still having problems with battery dying. I don't think it's the alternator. Thanks! Going to subscribe!
I had a squeal in my Ford Ranger at around 16 below, lived with it thought it was just the cold, discovered it was the alternator bearing that was squealing on startup. Discovered it when the alternator bearing froze up - breaking the belt and one of its mounting bolts.

Michael Luciano So the stereotype of an angry (emotional) person of little detailed knowledge being the image of lower class Republican must be correct. Although people are individuals, trends fluctuate and social classes evolve.
That belt screech is more like a Cruz or Phil Robertson.
Exactly
I had this issue a month ago and performed some poor diagnostic work. The belt had been replaced 2.5 years ago and I cavalierly assumed it wasn't the belt. In addition, the idler pulley was replaced a year ago and I eliminated that. So, I pressed the end of a hammer handle against the tensioner pulley and the tone of the squeak was altered. Hence, I replaced the tensioner. The problem did not go away. Next, I sprayed the belt and the squeak dissipated. Oops. This time, I purchased a quality Gates belt, not the $17.99 model I purchased last time. I could have returned the $39.99 tensioner, but the truck is 18 years old, and I left it in. Great video.
Thanks for the info! Havent had this problem yet but now I know what to do if it does
Ok , you found the missaligment..
Where is the fix?
Unbolt the nut and re set it?
"This is gonna be more annoying than listening to a liberal." I'm actually one myself and this was fucking hilarious.
Thanks very much for this video. It gave me some ideas to diagnose the squealing on my brother's 99 Dakota. The squealing we hear is mainly when he pushes in his clutch. I did replace the tension pulley about a year ago, so I hope it's not that.
Sounds like a worn thrust bearing on the crankshaft. Pushing in the clutch forces the crankshaft forward causing the pulleys to come out of alignment.
Great idea. One of my truck belts sqeals intermittently. Ill try water trick tomorrow. I only drive it 500 mikes/yr - mostly in SS&F. I can live with it.
Thanks.

Hi, Nice to find another video from you, addressing a current situation. I watched a few videos or your's, earlier this summer, helping me replace a fuel injector spider, in my 2000 Jimmy. or some other jobs on it, as there were 7rl major (and minor) issues addressed too effect Jimmy's resurrection. BTW, today, was it's 1st day on the road, undergoing driving trials, as it were, prior to his 1st big 'shake down cruise'. I haven't replaced any of the considerable skid plates, waiting to be sure nothing is leaking (brake lines, gas lines, oil lines to the new radiator, differentials, transfer case, etc....) Now running, there is something chirping a bit, and a 2nd, subtler intermittent squeaking. Nothing like the racket of your specimen. I'll try your methods tomorrow, but just wanted to say hello, and thank you again, for all your previous help!

Thanks a lot
very helpful information!!!
I watched this video a few times last year before I put it in storage when I was trying to diagnose a belt wear issue on my LT1 Camaro. Just recently subscribed though as you can tell by all my recent comments.
I was going through belts every 200 kms or so. They were wearing near the front of the belt (towards rad) about one rib length.
The water test indicated a misalignment but because not all my pulleys had the same lip thickness, a straight edge wasn't very helpful and it was hard to compare smooth surface pulleys to ribbed pulleys. I did buy a gates laser alignment tool and everything looked perfectly aligned. I checked multiple times.
I did notice a new wear pattern on my power steering pulley that was approximately 1 rib wide and it seemed to have a tiny bit of play in it. I could move the pulley back and forth a small amount. So I hate to admit it, but I took an educated guess and installed a new pump and pulley.
There's about 100kms on it and I don't see any wearing on the front of the belt like last time.
If I'm wrong, I'm thinking a thermal camera would show excessive heat where the pulley is misaligned. They're used for tire misalignment, so my logic is it should work for front engine accessories.
Good idea on the thermal camera!!
