When I start my 2008 chevy colorado 2.9l 2wd, it makes a chatter noise that sounds like a belt or pulley. This happens only on start up or putting it into gear, either reverse or drive, then throttle. I don't hear the noise when cruising down the road. Any insight would be greatly appreciated. Kind Regards..
Hello, Any special tools needed for replacing belts/pulleys/tensioners? I need to understand/learn how to take the belts off or release tensioner. I'm pretty efficient at mechanic work once I learn the proper methods. Advice appreciated! Thx!
If pulleys are squealing, change them asap. My idle pulley was squealing for about 1 month off and on. The day I bought a new one is the day the pulley bearing seized and the pulley came apart. The serpentine belt jumped off and I lost power steering, alternator, water pump. I was able to pull off the road and open the hood to let the engine cool off, temp was starting to rise. It took only about 10 minutes to replace the idle pulley. I also changed the tension pulley.
my engine on a 4 year old toyota makes a squeeling sound. but the weird thing is it only happens when the car is in DRIVE and the braked to a stop. the squeeling goes away the minute i let off the brake and the car moves or when i shift into park . is it still likely. a pulley?
randomrazr I have a manual transmission, but I am replacing pulleys and belts right now. Mine has had an intermittent squeak mostly on cold starts in the morning for 4-5 months. The last week it has started doing the the same as your Toyota. I can confirm the pulleys are bad on mine. 2005 Volkswagen Jetta
@@randomrazr Hello. My 2008 Accord EXL does the same. Only makes noise when in drive and reverse. Can you please let me know what was the problem and how you fixed it?
You are one of my favorite 1A Auto "stars!" Love the enthusiasm, the "duh" reenactments & how you make us all feel like "tah-dah" when we realize how to fix our problematic car issues. And how you say "vehicle" makes me smile everytime due to your accent. Truly appreciate you all!
If the chirpy/squeal/humming noise is heard on a cold start its either the water pump pulley or power steering. If the noise is not heard until the engine gets warm its often a tension pulley or idler pulley. If unsure, pull off the serpentine belt and start engine. Let it run no more than a minute. If no squeal or chirp noise you can be sure it's one of the pulleys or the belt itself. If you still hear the noise with the belt off you have an internal engine issue or problem with emissions.
Pulleys are such a overlooked car part that doesn't get replaced esp on an older car imo. I replaced basically almost all of them on my old 2010 Camry with 180k+ miles. After watching your videos I ordered a new Denso water pump and alternator from you guys and fitted it. Much better now. Along with 2 new belts Great channel and very helpful. 1A auto sells quality parts. Us guys and gals living on the East coast. The winter just destroys the cars.
Great video. I knew the issue with my truck was a pulley. A mechanic tried telling me my transfer case was bad. Thanks to your video, I figured it out myself. Bad pulley on my water pump (which explained my over heating issues. I went ahead and put a new water pump and serpentine belt. Problem solved. Thanks.
Regarding the pulley noises, my tundra is not squealing ,chirping, nor tapping. It's more of a dry rubbing sort of sound (like the sound Chewbacca makes only toned down) idk ,it's the best description of this noise I can compare to. It has the repetitive sound same uniform rhythm as it goes around,I am guessing since I can feel by hand on the cover while truck is running. I recently bought the aisin timing belt replacement kit ,after the operation was complete, drove about 50 or so miles, the noise was then present. Weird because I actually hears it while my stereo was on. Probably also I could feel change of performance through the pedal. I know my truck and any time there's issue I feel it via gas pedal. I am immediately aware of any new noise the arises. Someone else may not hear what I'm hearing or if so may say it's normal, but NO , NO ITS NOT NORMAL. That happened exactly at the Toyota service Department in Houma. Also the "professional" told me the rack and pinion was on the verge of failure, ready to set appointment for replacement. I said no. The "professional " said my power steering fluid is leaking everywhere. NOOOOOOO. If that were even remotely true I would have been adding power steering fluid constantly. Since I have owned this truck I never once added power steering fluid ever. Had this "professional " actually fulfilled his duty to investigate before making his diagnosis, such as cleaning the area where it was so called "leaking everywhere" , turned the wheel several times... there's no leak anywhere! Oh but he was hyped about that appointment to replace rack and pinion, which is a pricey part and procedure. How could he be firm with that false diagnosis? He never even checked to be sure IF it was actually leaking. I left a review regarding that incident, naturally greg leblanc toyota removed my review . I apologize for going off topic but I felt the need to mention the experience with a dealership service dept, knowing that all are not shady and I can only attest to my experience with this one... just stay focused when they drive a diagnosis not to be blindsided with false information. It's sad when you cannot trust your dealership service department. Automatically these "professionals" believe that girls are easy to manipulate. I wish I knew who to report that misdiagnosis to, apparently the company is not concerned with scamming consumers. So back to my pulleys, is there a serpentine belt pulley? And has anyone heard a noise such as what I described?
What a relief. The part of the video where you were describing the movements of the pulley being OK in one direction but a wobble being bad. Because my Pulley is moving in the directiob of the belt a little bit but it's not a wobble like as if it was a loose bearing
I really am not a car fanatic at all but this was a very easy watch. I just came from Pep Boys after having them fix my serp belt over the weekend. Heard a slight noise that wasn't quite a screech but still sounds a little bit off whenever I start the car (although, it's in and out, and of course, when the guy came out to hear it, it wasn't making that noise any of the 3 times I started the car). He said it was a pulley and not the belt they fixed, and that I should just wait for it to make that noise consistently before doing anything. The sound right to you?
Good afternoon, I have a 2011 Nissan Altima 2.5S ( special edition ). My brother bought me the car in 2021, from a private owner. drove this car for 2yr with this sound . Cranking the car up this noise is a little loud once I take my foot off acceleratord driving off it’s still makes this noise. It jerks as it reach up to 20 miles after reaching 20 miles car drives good on the road. Same crazy noise as you mentioned. Also once the car pulls off, it jerks as pressing down on the accelerator reaching 20 miles then the jerking stops. On yesterday it made this noise as I drove off it reach up to 54 miles made this humming sound release my foot it stops pressing down noise starts again. Car didn’t want to change gears. My brother put transmission fluid in drove pretty good once it got hot starting driving really slow had to pull over once it cooled off little bit finally made it home with my flashers on on a main highway drove 25-30 miles highway speed is 50 miles.
Thanks for the video - I appreciate you guys and gals taking the time to make these videos. I found this video very informative and learned a lot from it. I love A1 Auto videos!
Hey mate, what causes the pulleys to start playing up ? Is it just wear and tear overtime or is there something specific I can do to avoid this issue in the future
Took off my belt and gave everything a spin and a wobble, i originally thought the sound was coming from the crankshaft, but once the belt was off and i spun the water pump pulley, it squeaked and i realized i was about to sell a car with a water pump that might fail at any time. Thanks for the advice and I'm going to get that replaced pronto before i sell.
My car has been making a very loud squealing noise since I got my serpentine belt replaced. I took it back to the shop to get the belt tightened and it stopped. Though 2 days ago it made the noise again out of nowhere and it seemed to be louder and last longer then before. Previously, this noise would happen shortly after turning the AC on after starting my car. The instance 2 days ago occurred about 5 minutes after starting my car, a couple minutes after I had already turned the AC on.

Good video for explaining them. I think my Idler pulley is bad, the bearing. It's making such an annoying whine on cold start. Turning is very rigid. I thought if might be a bad PS Pump. But I've replaced my o rings on the PS Pump. Now I'm gonna replace the Idler pulley first and see if that solved it. The noise isn't comming from the PS Pump, which leads me think it's one of the Pulleys. 2008 TL Cheers
Yea I get chattering in my engine. I first I thought well it's getting colder, so maybe it's the engine just trying to heat up, but I'll be sure to check the pulleys. I still need to replace the valve cover gasket
Replaced the serpentine belt on my 09 Sienna roughly a year ago for this noise issue. Fixed the issue, but now it’s back only on cold starts. I’m thinking it may be a bearing, I’ll have to check them all out for too much play or for too much or too little spinning! Now, does the endless spinning issue only apply to idler pulleys, or also power steering and water pump pulleys?
Blessings and great info, I love your videos and I will look into my truck and see why is making a funny noise and the serpentine belt is coming off very slowly, will definitely check the pulleys thank you much and God Bless
I have a 2010 Toyota Corolla. I changed the alternator after it was squeaking. I fixed that sound, but now I have a squeaking noise at cold start, it kinda chirps up and down as the belt goes at its speed. It works, it goes away once it’s warmed up, I don’t really know where to start.
I’m getting lots of clicking but idk what pulley it is. Probably time to replace the belt anyway so I’ll be able to test them like in the video, thank you
Help! 2001 2500HD 8.1 sounds like the clutch or bearings in the a/c is freezing up. Replaced all the pulley' and tensioner. Along with clutch fan. Instead of replacing the unit and would also be a help if broke down on a trip. There should be a work around to be able to put a bigger idler pulley and a smaller belt...I just don't know how to do it. Maybe with a string to measure the new work around belt??? Because if you're belt breaks on a trip due to seizing pulley your done. If there was a work around, in 15 mins you'd be back on the road. Otherwise there's gonna be a tow bill and hotel costs that wouldn't be necessary. Then I could replace anything, to a point, frozen up at a later point in time. Oh, I have the 105 amp alternator. Thanks so much!!! Bob!
Thanks for the knowledge I feel some of these mechanics try to get over if they sense you have no knowledge of your issue fox run auto in bear de just tried to charge me 2,000 to fix a wobbly pulley smh
I’ve got a chirping sound coming from my engine. Because of this channel I know now what it might be. I’m going tomorrow to have it worked on and now because of this channel I won’t go in not knowing and possibly being taken advantage of.
Hello! I love that video. Ok I have a 2010 Chevrolet Equinox. And im have some weird noises coming from one of my pulleys. Really not sure which one. Can you give me some advice?
I’ve changed everything but alternator,Ac, and fan pulley. My truck still makes a very loud screeching sound during start up of my tundra. Sadly my alternator pulley gets quite warm during the start up/ squealing part. Just got another belt but it’s Toyota oem $.
You guys make some really great content! I was driving my 06 Corolla XRS in deep snow for a couple days recently, and my splitter foced snow and dirty slush up into the engine bay, fully packing it. The next time I started the motor it squealed like a car with belt slippage. Since it was within arms reach, I grabbed a can of belt conditioner spray and put a little squirt on there... and all hell broke loose! It sounded so bad, like a cacophony of tortured children and elderly souls crying out for me to shut the motor down right away, which I did. I'm about to spray it out with water today, but I was wondering if the bearings are supposed to be sealed or if there's potential that grit and soot got in there and washing it could actually resolve the issue?
What if you're hearing noise at specific RPMs? I notice a metallic spinning/grind noise only at 2000RPM. Could this also be a pulley/bearing? Or is it a sign of a bigger problem?
It might be the heat shield on your catalytic converter. Mine was making a metallic noise at 2000 rpm as well. I have a 2008 mazda 6 2.3l. I took mine to a muffler shop and they took off the heat shield. No more noise
I have a 2007 Nissan Altima replaced both front wheel bearing all the suspension good condition. but when turning to the passenger right side you hear a humming noise at low speeds then get louder going slightly over 55. Could it be bad pulley bearing, alternator pulley, power steering bearing. Maybe something else?!
I bought brand new belts but the squealing noise hasn’t stopped. Hi pitch squealing noise that is lound upon starting & the faster I go. The less noise it makes
Hello, I enjoy watching your videos I've been looking all over for a video for ' '97 Ford Explorer XLT Control Trac 4wd 6cyl 4.0l SOHC. I have a stuck bolt on my idler pulley. Every video I've seen so far is not for the correct car with a method that I don't really want to try on a vehicle that I haven't had long and there aren't any on 97 Ford Explorer idler pulley stuck bolt, everything is for crankshaft pulley or tensioner ect. I don't have access to power tools at the moment and I don't have access to a torch. I have one more challenge which is I have a wrist that's in a brace because it's healing from being broken 🤦🏾♀️.. what have you got for some ideas? Thank you in advance if you answered this.
My mothers van whines been a year like that I thought it was the transmission whine of death. 2010 Grand Caravan 3.3l. Noise is near the pulleys and get louder when accelerating even in park or neutral. I disconnected the alternator the sound stayed the same. Ill have to test by moving the pulleys I don't have a good enough ear anymore to do the stethoscope or long screwdriver method.
Question to anyone that can help.. i have a 2014 dodge charger hemi, ever since i got it, it has like a grinding kinda noise to it, i thought it was the belt but its not, IT DOES make the noise when the car is in idle so i was thinking that could be it, anyone have any recommendations?? not a squeaky noise, not a chirp, although it did once awhile back, like best way i can describe it, it is a grinding noise. help?
I have a 2020 Ford F250 Super duty 6.7 litre diesel. Sometimes I have a squeal, then after around 100km it goes away. then around 2-5,000 km it comes back again. My mechanic has replaced the bearings on the pulleys and the belt. Now around 18,000km later its back again
My fan is bobbing in and out and I have a loud chirping squealing screech and also like a can of gravel rolling around grinding sound. Also i felt performance problems driving too. Parked cuz im scared it sounds so bad... Loud. I had an intake leak for a while until I used blue devil 3 years ago.. I think the coolant ruined a pulley but my fan bobs around in and out slightly. I've never troubleshot any of this before
May of helped with my problem, but will find out. Was hearing whining noise so replaced the serpentine belt and noise got 2x louder n engine light came on. Thinking may be pulley or alternator going out.
I was hearing sort of grinding noise from the engine bay and during my visit to the workshop the mechanic told me that this noise is coming due to tensioner.....I just want to know is it safe to drive the car in such a condition as the mechanic told me that I can drive it .
I’ve just put on a new larger lighter pulled on the water pump(designed for the car), with a slightly larger belt; But now on cold start only it makes what sounds like a rub noise (sand paper like) per second for about 30 seconds or so until the engine gets warmer.. once warm it’s fine, could this be a bearing/lubricant or a tight belt issue maybe?
Hello, thank you for this useful video. My Honda CR-V I bought new just in December ‘20 with 1.6 diesel AWD with 9 speed ZF automatic has kind of rattling noise (pretty sure it’s not normal Diesel engine noise) from the front of the car which I assume is from the engine. I can hear it very clearly with air con off, windows shut. The noise can be heard only when hold my foot on the gas to crawl at the speed of around 9-15 mph which keeps it at low rev of around 1,000 or a bit lower. The noise lasts for as long as it’s in those conditions and go away when the transmission shifts to lower gear and the rev goes higher than 1,000-ish or when I speed up or take my foot off the gas. Do you think the noise comes from any of these pulleys or belt tensioner? Thanks so much in advance!
+Natthawat Soontornsook We wouldn't be able to diagnose an issue like that here, you may want to have a local mechanic take a look at it. Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c
I have a 1996 Chevy Express 1500 5.7. The serpentine belt keeps shredding. I notice the tensioner bounces, and I hear knocking noise.i changed the tensioner and idle pulley, it did the same thing. I removed the belt, checked all the pulleys. No noise. Can you give me some advice. Please. Thanks, Bobby
Hey man, so i got a squeaky belt on my 96 jeep cherokee, changed the belt to see if that was yhe issue. Still squeaks, not constant but annoying. The last. Elt i took off to check pulleys. My ac comp pulley has play and the bearing sounds shot. Thoughts? Could this cause a screechy belt??
I have a 2009 Impala that has a loud grinding noise like a pulley bearing that is out, but the thing is I removed the serpentine belt so all pulleys are not turning but the loud pulley bearing noise is still there. Its very loud but can not be one of the pulleys in this video shows. Whats up with that situation?
Love this channel. Has helped me with past things I wanted to fix. My 2006 dodge durango. Started to squeel as soon as I turn the A/C on and last for a bit before the noise stops. I havnt had time to really look at it. Do you think this is a pully issue or A/C clutch? Also is it necessary to replace the fan if it is the clutch? Thanks
So I'm hearing a loud topping noise after my belt has been replaced by a certified mechanic, but I'm a distant away from his shop right now. What do I need to do from here?
Good morning, I have a question? Honda Element I have a rebuild alternator 3 months ago , and now is making a grawning noise. What do you think could be ?
I hear a tapping noise on my truck. But I take the belt off start it quickly and the sounds gone with out the belt. I put it on and it’s there again. I can’t figure out if it’s a bad bearing in one of the pulleys. Any info would be awesome.
I changed my serpentine belt and AC belt with pulleys and tensioner's. Now after a week or so a taping sound has developed. It does not speed up or slow down with reving it just constantly tap tap tap. I adjusted the belt once it went away then it came back any ideas would be greatly accepted.
I have a loud squealing noise that almost sounds like it’s coming from the crank but I’m not sure and just don’t have the money to bring it to a shop. Any suggestions?
replace my serpentine belt the tensioner pulley and the pulley and still have a noise the noise increase and it only last till the fan turn on after the no more noise but if I turn the truck off it do it again
My 2007 Grand Prix was making a squealing sound when first started and cold but went away. Now it doesn’t and it is much louder at the same time losing about half of my power steering when I do have flood. Could it be pulley, Serpentine belt, bearings or power steering pump itself cuz really loud.
my car sounds like it has a turbo now, but I noticed, idler pulley is super shiny now. What does that mean? That means the bearing on the idler pulley is not as free as it should.. so it's not keeping up with the engine, causing the belt to wear out the metal to make it shiny? Any help would be cool
I have the squealing only when I’m drive and accelerating. The noise originates from the front lower driver side of the engine. Is that the pulley? (5.7 hemi 2012 ram 1500)
So I did the water test to the ribbed side of the belt and it stopped squealing for a second than the sound got louder and sounded like grinding coming from my ac compressor. I drove it around parking lot and then the steering got a little harder to turn. Now I am confused as to if my ac pulley is bad or if it is belt alignment or something else. Any thoughts? Please help
I have a 2015 Toyota Camry SE 72K miles and am hearing like a crickets noises as my car turns running few minutes .. i popped the hood n looked at the pulleys and look good but what is that noise .. sounded like the belt in engine .. my son was looking at it via FaceTime n he said probably a pulley issue but needs to actually look under the hood in real life. I don't want to take it to the dealership as prolly charge me $$$ to diagnose
If I’m able to wiggle the idler pulley just slightly, like as much as the tensioner did when you wiggled it in the video, does that mean I should replace it? I’ll try spinning it next, but I am able to wiggle my idler pulley but it just moves slightly. Plus, whichever pulley it is, I’ll hear a squeaking noise when I accelerate. My old belt broke off yesterday, so I put a new one on today and there’s still a squeak when I start the car and when I accelerate.
I have a 2017 grand cherokee before anything it started to make a squeaky, scratching sound, I then replaced the serpentine belt and idler and yet it still nothing has changed what could it be?

Good video for explaining them. I think my Idler pulley is bad, the bearing. It's making such an annoying whine on cold start. Turning is very rigid. I thought if might be a bad PS Pump. But I've replaced my o rings on the PS Pump. Now I'm gonna replace the Idler pulley first and see if that solved it.
The noise isn't comming from the PS Pump, which leads me think it's one of the Pulleys.

Thank you so much. Have been trying to explain to an auto shop the metallic chirping noise i keep hearing. I will be getting this fixed soon!
Yea I get chattering in my engine. I first I thought well it's getting colder, so maybe it's the engine just trying to heat up, but I'll be sure to check the pulleys. I still need to replace the valve cover gasket
Replaced the serpentine belt on my 09 Sienna roughly a year ago for this noise issue. Fixed the issue, but now it’s back only on cold starts. I’m thinking it may be a bearing, I’ll have to check them all out for too much play or for too much or too little spinning! Now, does the endless spinning issue only apply to idler pulleys, or also power steering and water pump pulleys?
Blessings and great info, I love your videos and I will look into my truck and see why is making a funny noise and the serpentine belt is coming off very slowly, will definitely check the pulleys thank you much and God Bless
Can you please put in your videos what tools to use and show as your using them. I would appreciate it, makes it a lot easier thanks.

“Chattering” noise when idling near pulleys
Turn on AC it goes away
Also, sluggish acceleration
Good video very informative, I have some chirping noises and mechanic said change the belt I’ll need to keep it for 2 hours at 65$ an hour
I have a 2010 Toyota Corolla. I changed the alternator after it was squeaking. I fixed that sound, but now I have a squeaking noise at cold start, it kinda chirps up and down as the belt goes at its speed. It works, it goes away once it’s warmed up, I don’t really know where to start.
Interesting. Just came back from the mechanic to have this exact problem fixed and wanted a better understanding of what the mechanic just did.
I’m getting lots of clicking but idk what pulley it is. Probably time to replace the belt anyway so I’ll be able to test them like in the video, thank you
Help! 2001 2500HD 8.1 sounds like the clutch or bearings in the a/c is freezing up. Replaced all the pulley' and tensioner. Along with clutch fan. Instead of replacing the unit and would also be a help if broke down on a trip.
There should be a work around to be able to put a bigger idler pulley and a smaller belt...I just don't know how to do it. Maybe with a string to measure the new work around belt???
Because if you're belt breaks on a trip due to seizing pulley your done. If there was a work around, in 15 mins you'd be back on the road. Otherwise there's gonna be a tow bill and hotel costs that wouldn't be necessary. Then I could replace anything, to a point, frozen up at a later point in time.
Oh, I have the 105 amp alternator.
Thanks so much!!! Bob!
I got a Mazda, 2009 model and found that as soon as ine part goes, they all go...so this video was very helpful. Thanks guys
Thanks for the knowledge I feel some of these mechanics try to get over if they sense you have no knowledge of your issue fox run auto in bear de just tried to charge me 2,000 to fix a wobbly pulley smh
I’ve got a chirping sound coming from my engine. Because of this channel I know now what it might be. I’m going tomorrow to have it worked on and now because of this channel I won’t go in not knowing and possibly being taken advantage of.
Hello! I love that video. Ok I have a 2010 Chevrolet Equinox. And im have some weird noises coming from one of my pulleys. Really not sure which one. Can you give me some advice?
I’ve changed everything but alternator,Ac, and fan pulley. My truck still makes a very loud screeching sound during start up of my tundra. Sadly my alternator pulley gets quite warm during the start up/ squealing part. Just got another belt but it’s Toyota oem $.
You guys make some really great content! I was driving my 06 Corolla XRS in deep snow for a couple days recently, and my splitter foced snow and dirty slush up into the engine bay, fully packing it. The next time I started the motor it squealed like a car with belt slippage. Since it was within arms reach, I grabbed a can of belt conditioner spray and put a little squirt on there... and all hell broke loose! It sounded so bad, like a cacophony of tortured children and elderly souls crying out for me to shut the motor down right away, which I did. I'm about to spray it out with water today, but I was wondering if the bearings are supposed to be sealed or if there's potential that grit and soot got in there and washing it could actually resolve the issue?
Did you figure it out?
nice car
Very detailed and perfectly explained great video
My first guess was a water pump. Now I have the skill to find the bad part. Thanks a lot 1A.
Thanks my brother for helping me out. Keep on sending them out....
What if you're hearing noise at specific RPMs? I notice a metallic spinning/grind noise only at 2000RPM. Could this also be a pulley/bearing? Or is it a sign of a bigger problem?
Same on my 2012 300
It might be the heat shield on your catalytic converter. Mine was making a metallic noise at 2000 rpm as well. I have a 2008 mazda 6 2.3l. I took mine to a muffler shop and they took off the heat shield. No more noise
Same problem my end
I have a 2007 Nissan Altima replaced both front wheel bearing all the suspension good condition. but when turning to the passenger right side you hear a humming noise at low speeds then get louder going slightly over 55. Could it be bad pulley bearing, alternator pulley, power steering bearing. Maybe something else?!
I bought brand new belts but the squealing noise hasn’t stopped. Hi pitch squealing noise that is lound upon starting & the faster I go. The less noise it makes
Great video. Your cars are such a frickin mess. How does a pulley get in this condition? Live up north! Great work!

Hello, I enjoy watching your videos I've been looking all over for a video for '
'97 Ford Explorer XLT Control Trac 4wd 6cyl 4.0l SOHC. I have a stuck bolt on my idler pulley. Every video I've seen so far is not for the correct car with a method that I don't really want to try on a vehicle that I haven't had long and there aren't any on 97 Ford Explorer idler pulley stuck bolt, everything is for crankshaft pulley or tensioner ect. I don't have access to power tools at the moment and I don't have access to a torch. I have one more challenge which is I have a wrist that's in a brace because it's healing from being broken 🤦🏾♀️.. what have you got for some ideas? Thank you in advance if you answered this.
My mothers van whines been a year like that I thought it was the transmission whine of death. 2010 Grand Caravan 3.3l. Noise is near the pulleys and get louder when accelerating even in park or neutral. I disconnected the alternator the sound stayed the same. Ill have to test by moving the pulleys I don't have a good enough ear anymore to do the stethoscope or long screwdriver method.
Dude you are always so informative love the way you do your videos great job
Just had all mine replaced on my 04 f150, not cheap, but nice and quiet now.
Thanks fam... Literally saving lives.
Question to anyone that can help.. i have a 2014 dodge charger hemi, ever since i got it, it has like a grinding kinda noise to it, i thought it was the belt but its not, IT DOES make the noise when the car is in idle so i was thinking that could be it, anyone have any recommendations?? not a squeaky noise, not a chirp, although it did once awhile back, like best way i can describe it, it is a grinding noise. help?
Never thought of using the screwdriver trick on a pulley! Thank you kind sir :-)
mine chirps and squeals at first start up , after awhile when warmed up goes away ?
Hey, if I'm not wrong. Are there two tensioners on every car out there? One for the V-belt and one for the Timing belt? Thanks!
Yes...
I have a 2020 Ford F250 Super duty 6.7 litre diesel. Sometimes I have a squeal, then after around 100km it goes away. then around 2-5,000 km it comes back again. My mechanic has replaced the bearings on the pulleys and the belt. Now around 18,000km later its back again
Excellent information on everything talked about, just some down to earth good info!
Keep up the good work!
My fan is bobbing in and out and I have a loud chirping squealing screech and also like a can of gravel rolling around grinding sound. Also i felt performance problems driving too. Parked cuz im scared it sounds so bad... Loud. I had an intake leak for a while until I used blue devil 3 years ago.. I think the coolant ruined a pulley but my fan bobs around in and out slightly. I've never troubleshot any of this before
I JUST SPENT A 1000 dollars fixing these in the shop!!!!
May of helped with my problem, but will find out. Was hearing whining noise so replaced the serpentine belt and noise got 2x louder n engine light came on. Thinking may be pulley or alternator going out.
I was hearing sort of grinding noise from the engine bay and during my visit to the workshop the mechanic told me that this noise is coming due to tensioner.....I just want to know is it safe to drive the car in such a condition as the mechanic told me that I can drive it .
Len makes the BEST vids... thank you
I like the prybar trick. Never thought of that.
exactly the sound my 2001 Suburban is making. Its going to the shop. Thanks
I’ve just put on a new larger lighter pulled on the water pump(designed for the car), with a slightly larger belt; But now on cold start only it makes what sounds like a rub noise (sand paper like) per second for about 30 seconds or so until the engine gets warmer.. once warm it’s fine, could this be a bearing/lubricant or a tight belt issue maybe?
Hello, thank you for this useful video. My Honda CR-V I bought new just in December ‘20 with 1.6 diesel AWD with 9 speed ZF automatic has kind of rattling noise (pretty sure it’s not normal Diesel engine noise) from the front of the car which I assume is from the engine. I can hear it very clearly with air con off, windows shut. The noise can be heard only when hold my foot on the gas to crawl at the speed of around 9-15 mph which keeps it at low rev of around 1,000 or a bit lower. The noise lasts for as long as it’s in those conditions and go away when the transmission shifts to lower gear and the rev goes higher than 1,000-ish or when I speed up or take my foot off the gas. Do you think the noise comes from any of these pulleys or belt tensioner? Thanks so much in advance!
+Natthawat Soontornsook We wouldn't be able to diagnose an issue like that here, you may want to have a local mechanic take a look at it. Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c
I have a 1996 Chevy Express 1500 5.7. The serpentine belt keeps shredding. I notice the tensioner bounces, and I hear knocking noise.i changed the tensioner and idle pulley, it did the same thing. I removed the belt, checked all the pulleys. No noise. Can you give me some advice. Please. Thanks, Bobby
THANK YOU, man!! I go to have my Pathy looked at with so much info.
Hey man, so i got a squeaky belt on my 96 jeep cherokee, changed the belt to see if that was yhe issue. Still squeaks, not constant but annoying. The last. Elt i took off to check pulleys. My ac comp pulley has play and the bearing sounds shot. Thoughts? Could this cause a screechy belt??
I have a 2009 Impala that has a loud grinding noise like a pulley bearing that is out, but the thing is I removed the serpentine belt so all pulleys are not turning but the loud pulley bearing noise is still there. Its very loud but can not be one of the pulleys in this video shows. Whats up with that situation?
Thank you, exactly the info I was looking for and clearly explained.
Love this channel. Has helped me with past things I wanted to fix. My 2006 dodge durango. Started to squeel as soon as I turn the A/C on and last for a bit before the noise stops. I havnt had time to really look at it. Do you think this is a pully issue or A/C clutch? Also is it necessary to replace the fan if it is the clutch? Thanks
+Jason Shaw Thanks for the feedback!

So I'm hearing a loud topping noise after my belt has been replaced by a certified mechanic, but I'm a distant away from his shop right now. What do I need to do from here?
Good morning, I have a question?
Honda Element I have a rebuild alternator 3 months ago , and now is making a grawning noise.
What do you think could be ?
Thank you that was some great info. Pretty sure mine is chattering ugh
I hear a tapping noise on my truck. But I take the belt off start it quickly and the sounds gone with out the belt. I put it on and it’s there again. I can’t figure out if it’s a bad bearing in one of the pulleys. Any info would be awesome.
Can your alternator bearing squeak?? I changed my idler pulley, tensioner pulley and my serpentine belt and I'm till hearing squeaking
I changed my serpentine belt and AC belt with pulleys and tensioner's. Now after a week or so a taping sound has developed. It does not speed up or slow down with reving it just constantly tap tap tap.
I adjusted the belt once it went away then it came back any ideas would be greatly accepted.
I also noticed some corrosion on the water pump could that be whata making that noise?
I start my truck up and hear the low sqeaking, spray water on the belt it goes away...serp belt?
I have a loud squealing noise that almost sounds like it’s coming from the crank but I’m not sure and just don’t have the money to bring it to a shop. Any suggestions?
replace my serpentine belt the tensioner pulley and the pulley and still have a noise the noise increase and it only last till the fan turn on after the no more noise but if I turn the truck off it do it again
I changed my alternator and decided to also change the belt but now my belt doesn’t move at idle. I’m going to have to figure out what’s going on
My 2007 Grand Prix was making a squealing sound when first started and cold but went away. Now it doesn’t and it is much louder at the same time losing about half of my power steering when I do have flood. Could it be pulley, Serpentine belt, bearings or power steering pump itself cuz really loud.
Came for the pulley info but MY GOD that Throttle Body is clean enough to eat off of!!!
+souLance Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c
My 2006 z71 makes grinding noise only when i turn on the AC. The AC works fine, but the noise is getting louder.
my car sounds like it has a turbo now, but I noticed, idler pulley is super shiny now. What does that mean? That means the bearing on the idler pulley is not as free as it should.. so it's not keeping up with the engine, causing the belt to wear out the metal to make it shiny? Any help would be cool
Excellent presentation!
Ok so I had my tentioner pulley replacd but car still making that same squealing noise... so how would I know which pulley to replace next
What I did with mt Tensioner, I sprayed it with Silicon lubricant and still no noise for more than a year now…
I have the squealing only when I’m drive and accelerating. The noise originates from the front lower driver side of the engine. Is that the pulley? (5.7 hemi 2012 ram 1500)
So I did the water test to the ribbed side of the belt and it stopped squealing for a second than the sound got louder and sounded like grinding coming from my ac compressor. I drove it around parking lot and then the steering got a little harder to turn. Now I am confused as to if my ac pulley is bad or if it is belt alignment or something else. Any thoughts? Please help
My 2006 qx56 Infiniti always squeals when it’s moist or wet outside. I changed one idler pulley and replaced the belt. What should I do?
I have a 2015 Toyota Camry SE 72K miles and am hearing like a crickets noises as my car turns running few minutes .. i popped the hood n looked at the pulleys and look good but what is that noise .. sounded like the belt in engine .. my son was looking at it via FaceTime n he said probably a pulley issue but needs to actually look under the hood in real life. I don't want to take it to the dealership as prolly charge me $$$ to diagnose
If I’m able to wiggle the idler pulley just slightly, like as much as the tensioner did when you wiggled it in the video, does that mean I should replace it? I’ll try spinning it next, but I am able to wiggle my idler pulley but it just moves slightly. Plus, whichever pulley it is, I’ll hear a squeaking noise when I accelerate. My old belt broke off yesterday, so I put a new one on today and there’s still a squeak when I start the car and when I accelerate.
An old broom handle is a good listening tool. After you shorten it.
I have a 2017 grand cherokee before anything it started to make a squeaky, scratching sound, I then replaced the serpentine belt and idler and yet it still nothing has changed what could it be?
yall are always awsome, great video
I get a chirping noise at low revs when moving off. Doesn't make a noise when stationary.
