Had this problem on my 1997 mustang GT (stock 4.6L v8 sohc) I replaced the tensioner that already had a pulley attached to it and it fixed the problem. If you have this exact same vehicle do NOT get the gates tensioner it doesn't line up and will fail within a year, get the Dorman or oem one. Thanks McCuistian you are by far the best automotive channel on here!
I have the same vehicle and I’m getting a rattling noise even after replacing the whole assembly with a duralast brand one. When I tighten the pulley the rattling stops but then comes back when I release it to its proper position. The noise is driving me nuts and if you have any idea what I should do then I’d highly appreciate it. Maybe duralast isn’t good for this particular car?
DAMN...5 days ago my car was making this exact sound. I assumed it had to do with the belt...but most people say loose belts male a squeaky sound. But I tried diagnosing and test driving to see if there's a pattern, and this video exactly shows the randomness of when I hear it, and how it would go away. Merci beaucoup for the video, now I know that it is indeed a belt issue.
My pulley def wasn't scraping. Replacing the belt made the noise less frequent. What seems to happen, tho, is that the tensioner moves in jerks instead of fluidly. Going to put some oil on the spring and pivot.
Exact same thing I hear at our Mitsubishi Montero. It's on the alternator and steering pump belt though. Will try to check the tensioner it's the same problem as yours. Thanks man! More power to you! 👌🏻
I love you man! This is the thousand beetles getting crushed noise I hear from my car under load or going on an uphill drive. Finally I figured thanks to you! Super thanks!!!
Damn lol. I'm gonna use this to describe the noise to my service advisor. On cold start, when accelerating, especially under load disappears after car warms up.. Not sure why the beetle put its nest in my car.
I've changed the pulley, tensioner and the belt all three. The noise is still deya. I am assuming maybe loose exhaust front from the exhaust manifold end?
My serpentine belt got replaced. I thought that was the issue. I have the exact sound like that. Now i know now what to buy. Thank you for the video you shared.
Thanks for the help mate. Had the same noise. Told many people it sounds like someone taking an ongoing poop of diarrhea.but they couldn't figure it out.
I have this rattling noise too when I turn on the AC but it doesn't sound so constant. I'm changing it tomorrow and see what happens. Thanks to this video as I was hoping it was not my AC compressor, as it still cools the car pretty fast and cool.
im having this same issue now. barely hearing it a few days ago, haven't taken anything apart just been doin my youtube research before i head under hood, ive checked the belt and it looks good my next phase is to remove the belt and spin all pulleys manual.
Thank you! My 2004 Grand Marquis has just started making that same noise intermittently, always when the AC is running. and I could see the tensioner vibrating but it was not making the noise at the time.
Wow really? Well my tensioner shakes a lot when I turn ac on so I think replacing it would still be a good idea I hope I don’t have any alternator issues
That's the pulley from the tensioner, had the same noise on my truck, it was caused because the tensioner bolts were overtighted and the pulley was scratching the block, in the end the pulley broke along with the belt, beware and check it
Bro thanks so much, i have a 2005 Corolla and the shop just change my serpentine belt tensioner and ya it was overtighten. It was making a knocking noise when i put it in drive or reverse but only when the ac is on. So i loosened it a little and the noise was gone. Thanks again bro 👍👍👍
2010 Camry: Have similar rattle sound, only when AC is on. Turn compressor off and just run the blower & sound goes away. 2 AC Repair shops said it was the compressor (just listening) w/out detailed diagnosis. Around $2,000.00. 3rd garage said it might just be a bad Tensioner, which I'm hoping for. Would be much less.
Sounds like that are often diagnosed as a bad component - usually the most expensive one - by some shops. Belts and pulleys can make sounds that are dreadfully misleading. You did good getting another opinion after those 2 shops.
@@McCuistian I'm still debating which shop to choose. Obviously, I'm leaning towards the shop that said it may just be the tensioner, but it was just a garage.

Mine makes this similar sound when AC is on and goes away when I turn AC off , but still comes on regardless sometimes , could that sound be this problem too ?
Its not your A/C clutch failing i have a dodge with a brand new A/C compressor and clutch and it did exactly what you described when i would turn on the air the tensioner would make a racket when i would turn the air off the noise would stop reason being is when the A/C is turned on its putting more stress on the worn out tensioner then when its turned off. I replaced my tensioner and no more noise!
I notice my car does the same thing.When you initially start it, it does not do it.But as the car is starting to warm up it does it.Then when the car is warm up it goes away does yours does the same thing get back to me thanks.
Nasty FingurZ My car makes a similar noise , but not as loud. Like you said. Its more noticeable shortly after I start it up. After its warmed up and I drive it for a bit , its tends to go away.. Getting a new tensioner when replacing timing belt should fix the problem.
Nasty FingurZ my 04 Pontiac dose the same thing start it and you get a high pitch speaking sound then as it warms up it goes away but when I step on the accreditor it's comes back being loud it's the weirdest thing
Man- I’ve replaced the belt, the tensioner bolt and the AC compressor and I still have a squeak (all professionally done). Maybe I’ll have the shop check this out.
Same noise on my car, but can only hear it in the cabin at a stop light. Once I release the brake and move forward the noise goes away. Noise seems less after car is fully warmed up too.
@@randyu8688 I haven't addressed the problem yet!! So, I don't have an answer. I think part of the noise comes from the hood vibrating. I think I need to adjust the hood somehow.
Solution found I think. Hood apparently loose. Press down on the front corner and hear squeak. So I adjusted the little bolt with a rubber bumper so the hood is not as loose after it's closed. Apparently, the engine vibrates more at a stop sign and that's when the hood rattles.
My car did the same noise u took it to my friend thinking it was the alternator he said no it was a pulley sure enough he was right he owns a tire shop
I have a chirp noise. I replaced the sepertine belt,, the belt tensioner, the idler pulley, the power steering pump and checked the A/C compressor and is fine and the noise is still there.. please someone help idk what to do anymore to make that stop. It only does the noise when i first start it up, then as the car warms up it goes away
Get a spray bottle and spray each pulley - if the belt slips worse, it's a problem with the tensioner. If the chirp goes away, it's a pulley alignment issue. The pulleys all have to be perfectly in line. If the crankshaft pulley is coming apart (the outer part and the inner part have rubber between them) it can cause that.
i have a 04 acura with a J32 and it make almost a click click click noise from the tensioner every time the A/C is on. it sometimes does it at start up like yours. i pushed on the top part of the belt and in turn it made the tensioner move and i heard the same noise. so i think my noise if from the serp belt tensioner. did u ever fix the noise? i can post a vid of my car to see if yours is the same noise. after i figured it was the tensioner i ignored it. i took the belt off early this summer and had really good tension and no play side to side so i just ran it
My s10 has the same noise I have replaced the tensioner put a new belt and new alternator and still have the same noise. It’s there at idle but very quiet but when I turn the AC in its gets louder would it be my AC compressor?
My wife's audi had been making similar noises, more of a clicking noise but only while it was in gear or climbing hills...the longest time I thought my wife's engine or transmission was about to shit the bed until I really looked into it..thought shit, maybe cv axles 🤔. Nah they were good..which lead me to think something serious in either the engine or transmission was failing and could go out any given moment. Come to find out, it was just the tensioner pulley.
Mine does too only at idle while In drive. Mine sounds a bit less noisy and more if like I had loose change rattling inside my car but same chirpy sound
I have the same issue. It becomes noticeable when the AC or Heat kicks on and stops when the compressor stops like in this video. However, I noticed that slightly feathering the accelerator will trigger it again. I'm assume this is because of the added tension on the tensioner. Would this line of thought sound reasonable to you? Thanks in advance for any input you can give.
The tensioner has a damper inside by the spring that you can't see without taking the tensioner apart, and when that damper wears out it does this. I replaced the tensioner on my Explorer about 2 years ago for the same reason.
I have a 2014 highlander that would make this faint clanking sound, mostly noticeable waiting at the drive thru and if i were next to the building. But this only was with the ac on but now its when accelarating from a stop or making a turn then stepping on the gas the first 3 second there some clanking noise then goes away. Can it be the belt tensioner or the AC compressor clutch?
did It mainly do this while idling in gear an at low rpms. and whith the ac/heat on? I think mines rattling but it really only does it in the above senarios.
inside the tensioner there is something kind of like a brake shoe and when it wears out the tensioner causes this kind of problem but it's usually worse under a load and at low RPM
+McCuistian yeah I have a grand am... but I replaced tensioner about a year ago I dont think it made the noise back then. jus replaced it due to a squeak I was tracking down. alot of gm parts now a days are crap so im thinkin its the tensioner. plus I got it at autozone...
+McCuistian yeah I think I just got a ac delco I believe. gonna check it out some more but thinks for the info. ill probly end up goin with the brand you suggested im pretty sure its the tensioner. thanks!
I just replaced my drive belt yesterday and so far the noice hasn’t come back. Do you guys think it was due to the worn out belt or my tensioner is able to hold for a bit longer since it’s tighter now?
@@McCuistian So far it seems like its gone. The belt was very cracked. I'm hoping the lack of tension was the issue. I have an Tigershark engine 2.4 and the tensor is hydraulic and it has been quiet ever since. My rule of thumb is wait about two or three weeks to see any changes. Its the second time i replace the band but my car has high mileage
Nope - not this time. The tensioner took care of the problem - people drive this car every day and it has never needed a compressor clutch... there's a LOT more to a tensioner than meets the eye - a damper inside the tensioner - sort of like a brake shoe - wears out and causes this, usually. Other things can cause it, but according to Gates, the tensioner should be replaced every time the belt is replaced.
I have a pt cruiser that has the same sound.. The previous owner recently replaced the compressor.. Maybe the old one damaged it.. Drove it for a month before noticing the noise.. I thought it was a lifter
@@McCuistian I have a Honda Odessy with same issue. Question I have is there are two parts one is a tensioner pulley and one is the full tensioner pulley assembly, which one do i get the assembly is a lot more money.
Hi, this sometimes can sound like a bad power steering pump? I have a Buick Century Custom 1999 with a new power steering pump, new water pump, and it still sounding like a bad power steering.
what kind of belt do you have on it? Because if it's one of those shiny Dayco belts with a fluted cuts it will sound like a bad power steering pump and you may have another pulley that is blessed with a bad bearing too
+McCuistian My electromechanical says that the a/c compressor clutch is bad, he told me that the sound comes from there, but I don't know, when I turned on the a/c the sound calms down.
Need a little help here! I can’t hear what they’re saying in this video! So the noise causing issue was a bad tensioner, bad belt or stretched belt, bad pulley, water pump, all of the above or what??? Please help!
What water pump? How does water pump fit into accessory drive belt at all??? Instead of being a honda owner st soul while driving a BMW, juat replace belt/belts, tensioner/tensioners, Idler pulley and whatever else pulleys are replaceable, instead of replacing just one thing, it just doesn't work like that based on physics....well and common sense ofcource
Its a fault in the Belt Tensioner design,I can see where there's a Gap and the arm of the Tensioner makes contact with the stationary part ,,if you look carefully while is Running with the Ac on it becomes visible to the Eye( there's a price to pay for aftermarket poorly designed parts) It occurs to me that installing a piece of thin Rubber inside the Gap will resolve the Issue....For how Long?... till Murphy interferes ;)
Remove the belt and start the engine to see if it makes the same noise - while you have the belt off, spin each pulley to make sure they're all spinning smoothly and without worn bearings.
+McCuistian I took the belt off and turned the engine on. It still makes that noise. I can't turn the bottom pulley by hand. But it turns without the belt attached when I turn the engine on. Very frustrating!! I am driving a 2001 Audi A4 Quattro 2.8L. If you have any other advice please do tell. Thanks.
Hi, thanks for your video, I had the same problem with my 2006 Nissan Altima 2.5s, but in addition to this sound, I had a squeaking sound when I turn on the AC , I replaced the Tensioner, and the squeaking sound gone, but I still got this sound like the one you had in your car that keeps coming and going. where do you think it is coming from? or what is broken? Thanks again.
Have this same issue with my 2012 Ford Explorer XLT, 3.5. I replaced the tensioner with an OEM one, new belt, new AC compressor and cured the issue for about a week but again, having this issue. I noticed the new belt was noticed shorter than the old one and I noticed it intensifies the rattle when the car is running, AC is on and open the doors (dome lights on) or roll the windows up/down (electric). New battery about 6 months ago. Starts up with no issues, no dimming of lights or electrical issues. Think it may be the alternator? Thanks!
Does it intensify when you turn the blower on high or the headlights on? Because the dome lights don't pull all that much current. Interesting situation.
My 2013 mustang gt makes this kind of noise when I cold start it and increases with rpm, but it goes away when the car gets warm. Bad belt or bad pulley? Or both? Lol
I fucking replaced the alternator rectifier on my Toyota before finding out it was the damn tensioner... I put a new belt on and the noise got worse, that's how I found out.
McCuistian, my 92 buick regal just started making that noise. How do I fix myself? can you help me out by letting me know what part I need to buy and is it something I can do myself?
You take the belt off, spin every pulley to make sure there isn't a bad bearing somewhere, and replace the belt and tensioner if you don't find any rough or loose bearings. If you do, that component needs to be replaced. Make sure you know how the belt is routed and make sure you don't get in over your head.
McCuistian ok thank you. And one more question, can I drive the car while it’s making this noise? And I need to get it home from where I parked it at but am worried to drive it. I appreciate your help as well.
I have the same noise in my car (Nissan X-trial 2008) when i start it and i can hear it more clear when i m inside the car. But this noise goes when my car is running at speed and when my car slows down again the noise starts again. In my case its not affected with A/C or A/C fan start and stop. This sound started first time when my car front bumper slightly hit the back of another car in front of me. Even the damage in my bumper is not noticeable at first site. Please guide me what can be the reason for this noise in my case. Your early response means a lot.
On the inside of that tensioner at the hub where the spring is located there is a damper. It's almost like a brake shoe and it's worn out. That part of the tensioner is something you cannot see but when it wears out the tensioner will bounce and make noise like that.
Hello sir, I have an 04 expedition my belt came off (shredded) and the pulley was destroyed. I only replaced the tensioner pulley, but it's still making that noise, should I replace the whole tensioner?
Not only should you replace the tensioner (there are other parts of it you can't see that wear out), but check all the other pulleys and make sure they spin freely and are in line with one another.
Hello. I have replaced crankshaft damper pulley ago 4days. I have exactly like this noise and my power steering so stiff its really hard to turn. it makes weird noise when turning. Also I replaced power steering pump belt but it wasnt original bmw belt. So do you think belt causes all this noises and hard steering? or crankshaft pulley
Thanks for answer. I just checked this morning. steering belt turning without problem. I start thinking that its about steering pump or rack which will cost me a lot. Still i will start with replace belt hopefully it will help.
Yes absolutely. Gates is very hit & miss with the quality of their tensioners. l've seen some Gates tensions new out of the box that were wobbly and couldn't be installed. l think some of them are made in America and some are made in China. OEM is usually the best bet when it comes to tensioner pulley assemblies but even the OEM ones l always repack the bearings before l install them because many times they only come with a minimal amount of grease in the bearings and they usually use the cheapest grease too, which guarantees they won't last as long as they should. l replace the stock grease with a synthetic high temp red grease, then install.
I love youtube. Now I can tell the guy exactly what I need rather than "some noise come from deya".
God forbid he does the job he is paid for
yah me too.. I have the same noise from my lancer.
Lol yes you can 😂

Important lesson that bad belt assembly doesn’t always “squeak” like some believe. Mine makes a sound like this, intermittent clacking/grinding.
That’s what I’m hearing on my 2011 maxima when deceleration or accelerating at slow speeds
Worn belt tensioner allowing the tensioner wheel to scrape against the timing chain cover.
Replace tensioner
Im having the same prob it makes my battery light come on
No the tensioner vibrating due to stretched belt
Mine seems to have a loose bearing on the pulley. Might replace that, first.
My pulley def wasn't scraping. Replacing the belt made the noise less frequent. What seems to happen, tho, is that the tensioner moves in jerks instead of fluidly. Going to put some oil on the spring and pivot.

Mine makes a similar noise on a cold start could it be the belt or the starter because after the car warms up the car is quite
I have the same it is probably the belt tensioner bearing
Same as me it make sound when it cold but when is warm the sound is little
I noticed it vibrates when it squeaks and when it clicks it doesn't vibrate but doesn't squeak. Mine does the total opposite lol
Same noise on my car, but can only hear it in the cabin at a stop light. Once I release the brake and move forward the noise goes away. Noise seems less after car is fully warmed up too.
Would u get a vibration too ? Like in intervals ? How did u fix it???
@@randyu8688 I haven't addressed the problem yet!! So, I don't have an answer. I think part of the noise comes from the hood vibrating. I think I need to adjust the hood somehow.
I get that too And I don’t have the aircon on only when I’m at a red light and it’s also random
Solution found I think. Hood apparently loose. Press down on the front corner and hear squeak. So I adjusted the little bolt with a rubber bumper so the hood is not as loose after it's closed. Apparently, the engine vibrates more at a stop sign and that's when the hood rattles.
I know on the 07 Ford Focus it's a design flaw. Simply replacing it will only solve the problem temporarily
Sounds like flock of pissed off cicadas
My car did the same noise u took it to my friend thinking it was the alternator he said no it was a pulley sure enough he was right he owns a tire shop
I have a chirp noise. I replaced the sepertine belt,, the belt tensioner, the idler pulley, the power steering pump and checked the A/C compressor and is fine and the noise is still there.. please someone help idk what to do anymore to make that stop. It only does the noise when i first start it up, then as the car warms up it goes away
Get a spray bottle and spray each pulley - if the belt slips worse, it's a problem with the tensioner. If the chirp goes away, it's a pulley alignment issue. The pulleys all have to be perfectly in line. If the crankshaft pulley is coming apart (the outer part and the inner part have rubber between them) it can cause that.
i have a 04 acura with a J32 and it make almost a click click click noise from the tensioner every time the A/C is on. it sometimes does it at start up like yours. i pushed on the top part of the belt and in turn it made the tensioner move and i heard the same noise. so i think my noise if from the serp belt tensioner.
did u ever fix the noise? i can post a vid of my car to see if yours is the same noise. after i figured it was the tensioner i ignored it.
i took the belt off early this summer and had really good tension and no play side to side so i just ran it
Replacing the belt tensioner took care of the one I was working on
Crankshaft pulley if you replaced everything else if not harmonic balancer pully
McCuistian which tensioner? Serpentine or timing?
My s10 has the same noise I have replaced the tensioner put a new belt and new alternator and still have the same noise. It’s there at idle but very quiet but when I turn the AC in its gets louder would it be my AC compressor?
I'm having the same issue, did you find out the solution?
Did you found the issue?
Latin Rox no I put a new ac compressor and a new ac Delco tensioner and new belt still does it when I turn the AC on
Does this also cause like a vibration type of sensation while on drive?
Definitely the sound
My wife's audi had been making similar noises, more of a clicking noise but only while it was in gear or climbing hills...the longest time I thought my wife's engine or transmission was about to shit the bed until I really looked into it..thought shit, maybe cv axles 🤔. Nah they were good..which lead me to think something serious in either the engine or transmission was failing and could go out any given moment. Come to find out, it was just the tensioner pulley.
Shit mine makes it when I’m in drive
Did you fix it?
Mine does too only at idle while In drive. Mine sounds a bit less noisy and more if like I had loose change rattling inside my car but same chirpy sound
Spray water on the belt if the noise stop that is bad belt noise after spray water nothing changes it's belt tensioner
I have the same issue. It becomes noticeable when the AC or Heat kicks on and stops when the compressor stops like in this video. However, I noticed that slightly feathering the accelerator will trigger it again. I'm assume this is because of the added tension on the tensioner. Would this line of thought sound reasonable to you?
Thanks in advance for any input you can give.
The tensioner has a damper inside by the spring that you can't see without taking the tensioner apart, and when that damper wears out it does this. I replaced the tensioner on my Explorer about 2 years ago for the same reason.
Good video sir
Just got a new tensioner and it's doing the same!
Same here, did you change your belt ?
I have a 2014 highlander that would make this faint clanking sound, mostly noticeable waiting at the drive thru and if i were next to the building. But this only was with the ac on but now its when accelarating from a stop or making a turn then stepping on the gas the first 3 second there some clanking noise then goes away. Can it be the belt tensioner or the AC compressor clutch?
It's difficult to say just listing to a description. I would remove the belt and carefully inspect everything that the belt spins
did It mainly do this while idling in gear an at low rpms. and whith the ac/heat on? I think mines rattling but it really only does it in the above senarios.
inside the tensioner there is something kind of like a brake shoe and when it wears out the tensioner causes this kind of problem but it's usually worse under a load and at low RPM
+McCuistian yeah I have a grand am... but I replaced tensioner about a year ago I dont think it made the noise back then. jus replaced it due to a squeak I was tracking down. alot of gm parts now a days are crap so im thinkin its the tensioner. plus I got it at autozone...
+maaat65 some of those aftermarket tensioners will go bad within a year and I've seen it repeatedly the best one to buy is Gates
+McCuistian yeah I think I just got a ac delco I believe. gonna check it out some more but thinks for the info. ill probly end up goin with the brand you suggested im pretty sure its the tensioner. thanks!
THAT SHIT HAPPENS TO MINE WHEN I ACCELERATE AT ABOUT 3 K RPM
did u fix it?
i hear this sound while drive at 40mph or faster but when im at a stop sign or stop light the sound stops. what you think is going on?
I got same, found any solution?
Sounds like Dr. Phil is narrating this
Naw... that's me.
Should you change the idler pulley when you change the belt tensioner 👍🏻
Only if it's loose or noisy
What other sound if sound like the kricik kricik sometimes only
I have a bmw 1998 z3 That makes this exact sound when the engine warms up, but only when it’s cold outside.
Try putting car in drive and then listen. Or neutral and rev 1.7-2k it will chirp or show movement
I just replaced my drive belt yesterday and so far the noice hasn’t come back. Do you guys think it was due to the worn out belt or my tensioner is able to hold for a bit longer since it’s tighter now?
If the noise is gone, just see if it comes back. Sometimes the belt is all it needs - the belt on this Crown Vic had already been replaced.
Naaaawwwwww. You gotta replace rear differential fluid filter in order to fix it for good
@@McCuistian So far it seems like its gone. The belt was very cracked. I'm hoping the lack of tension was the issue. I have an Tigershark engine 2.4 and the tensor is hydraulic and it has been quiet ever since. My rule of thumb is wait about two or three weeks to see any changes. Its the second time i replace the band but my car has high mileage
It Looks like The A/C Compressor Clutch is Messing Up 😮
Nope
Its the Ac compressor clutch dragging...happened on my Camaro before
Nope - not this time. The tensioner took care of the problem - people drive this car every day and it has never needed a compressor clutch... there's a LOT more to a tensioner than meets the eye - a damper inside the tensioner - sort of like a brake shoe - wears out and causes this, usually. Other things can cause it, but according to Gates, the tensioner should be replaced every time the belt is replaced.
I have a pt cruiser that has the same sound.. The previous owner recently replaced the compressor.. Maybe the old one damaged it.. Drove it for a month before noticing the noise.. I thought it was a lifter
@@McCuistian I have a Honda Odessy with same issue. Question I have is there are two parts one is a tensioner pulley and one is the full tensioner pulley assembly, which one do i get the assembly is a lot more money.
@@tiffanyv6634 I'd replace the whole thing - just replacing the pulley won't do anything.
Hi, this sometimes can sound like a bad power steering pump? I have a Buick Century Custom 1999 with a new power steering pump, new water pump, and it still sounding like a bad power steering.
what kind of belt do you have on it? Because if it's one of those shiny Dayco belts with a fluted cuts it will sound like a bad power steering pump and you may have another pulley that is blessed with a bad bearing too
+McCuistian My electromechanical says that the a/c compressor clutch is bad, he told me that the sound comes from there, but I don't know, when I turned on the a/c the sound calms down.
The tensioner has more of a load on it when the A/C compressor is engaged.
@@McCuistian Dayco or Continental auxiliary belts ?.
It can...
Just open the hood and voila la. Lol
Water pump is about to go out. Replace it before it turns into burnt toast.
I have a 2005 Nissan titian and I change the tensioner pulley and the belt but it's still making that same noise
Need a little help here! I can’t hear what they’re saying in this video! So the noise causing issue was a bad tensioner, bad belt or stretched belt, bad pulley, water pump, all of the above or what??? Please help!
Tensioner... Also replace the belt
@@McCuistian Thank You 😊 very much Sir! You are Highly Appreciated!
@@McCuistian👍🏽👍🏽👍🏽😊😊😊
What water pump? How does water pump fit into accessory drive belt at all???
Instead of being a honda owner st soul while driving a BMW, juat replace belt/belts, tensioner/tensioners, Idler pulley and whatever else pulleys are replaceable, instead of replacing just one thing, it just doesn't work like that based on physics....well and common sense ofcource
Its a fault in the Belt Tensioner design,I can see where there's a Gap and the arm of the Tensioner makes contact with the stationary part ,,if you look carefully while is Running with the Ac on it becomes visible to the Eye( there's a price to pay for aftermarket poorly designed parts) It occurs to me that installing a piece of thin Rubber inside the Gap will resolve the Issue....For how Long?... till Murphy interferes ;)
Cảm ơn bạn chia sẻ tiếng kêu của lốc điều hoà ,
You're welcome!
my engine is making the same noise. I just replaced the tensioner and serpentine belt. Any suggestions?
Remove the belt and start the engine to see if it makes the same noise - while you have the belt off, spin each pulley to make sure they're all spinning smoothly and without worn bearings.
+McCuistian I took the belt off and turned the engine on. It still makes that noise. I can't turn the bottom pulley by hand. But it turns without the belt attached when I turn the engine on. Very frustrating!! I am driving a 2001 Audi A4 Quattro 2.8L. If you have any other advice please do tell. Thanks.
I would suspect the problem in the timing belt area
Because the bottom pulley is the crank pulley, bolted directly to the crank shaft. If you can turn that by hand, you're pretty strong.
I hear this noise on my 14 Camry when I put it in DRIVE or REVERSE. Can it be this?
When a/c on? Did you fixed it?
Hi, thanks for your video, I had the same problem with my 2006 Nissan Altima 2.5s, but in addition to this sound, I had a squeaking sound when I turn on the AC , I replaced the Tensioner, and the squeaking sound gone, but I still got this sound like the one you had in your car that keeps coming and going. where do you think it is coming from? or what is broken? Thanks again.
If its only when you turn your ac on, its a bad bearing in the ac compressor. If its all the time, its a tensioner pulley gone bad
+71sc502 yes it was the compressor bearing, Thanks again.
Np man
Have this same issue with my 2012 Ford Explorer XLT, 3.5. I replaced the tensioner with an OEM one, new belt, new AC compressor and cured the issue for about a week but again, having this issue. I noticed the new belt was noticed shorter than the old one and I noticed it intensifies the rattle when the car is running, AC is on and open the doors (dome lights on) or roll the windows up/down (electric). New battery about 6 months ago. Starts up with no issues, no dimming of lights or electrical issues. Think it may be the alternator? Thanks!
Does it intensify when you turn the blower on high or the headlights on? Because the dome lights don't pull all that much current. Interesting situation.
@@McCuistian regardless of the blower speed, and headlights usually on
@@ritoandrade3732 the only thing that changes when you open the door is current load.
@@McCuistianthe AC blower speed does affect the rattling noise, any suggestions to cure the issue?
@@ritoandrade3732 Pull the blower and look at it. May be a problem with that.
My 2013 mustang gt makes this kind of noise when I cold start it and increases with rpm, but it goes away when the car gets warm. Bad belt or bad pulley? Or both? Lol
Put a new belt new tensioner 2 times in a 2 years tensioner still makes noise
I fucking replaced the alternator rectifier on my Toyota before finding out it was the damn tensioner... I put a new belt on and the noise got worse, that's how I found out.
McCuistian, my 92 buick regal just started making that noise. How do I fix myself? can you help me out by letting me know what part I need to buy and is it something I can do myself?
You take the belt off, spin every pulley to make sure there isn't a bad bearing somewhere, and replace the belt and tensioner if you don't find any rough or loose bearings. If you do, that component needs to be replaced. Make sure you know how the belt is routed and make sure you don't get in over your head.
McCuistian ok thank you. And one more question, can I drive the car while it’s making this noise? And I need to get it home from where I parked it at but am worried to drive it. I appreciate your help as well.
@@kygerhamilton9939 I can't say without having seen the vehicle -
My ford fusion makes the same noise when I put D in gear.
Mine sounds like glass bottles hitting eachother, any idea?
Why off A/C the noise is gone?
Thank you so much
thank you
My car makes this sound but only at idle. Least i know what it is now
Northern Rails is it the same problem if it does it during idle? My car sounds more of a rattle than a squeak. It gets worse with AC on too
What was it ?
I have replace thats part, just A week, and noise come again 😢
I have the same noise in my car (Nissan X-trial 2008) when i start it and i can hear it more clear when i m inside the car. But this noise goes when my car is running at speed and when my car slows down again the noise starts again. In my case its not affected with A/C or A/C fan start and stop. This sound started first time when my car front bumper slightly hit the back of another car in front of me. Even the damage in my bumper is not noticeable at first site. Please guide me what can be the reason for this noise in my case. Your early response means a lot.
Check the fan to see if it is contacting the shroud.
Have the same issue (Mazda Cx-7) do you find an explanation?
what is the cause of the noise? sorry, i couldnt really hear the explanation
thank you
On the inside of that tensioner at the hub where the spring is located there is a damper. It's almost like a brake shoe and it's worn out. That part of the tensioner is something you cannot see but when it wears out the tensioner will bounce and make noise like that.
Hello sir, I have an 04 expedition my belt came off (shredded) and the pulley was destroyed. I only replaced the tensioner pulley, but it's still making that noise, should I replace the whole tensioner?
Not only should you replace the tensioner (there are other parts of it you can't see that wear out), but check all the other pulleys and make sure they spin freely and are in line with one another.
Where are the other pulleys
The belt goes around them - take the belt off and you can feel the other ones.
My Toyota Camry 2014 started making that noise but only when my AC is on and I take off. I'm not sure what it is or how to fix it. 😰
Hello. I have replaced crankshaft damper pulley ago 4days. I have exactly like this noise and my power steering so stiff its really hard to turn. it makes weird noise when turning. Also I replaced power steering pump belt but it wasnt original bmw belt. So do you think belt causes all this noises and hard steering? or crankshaft pulley
Pulley alignment is a common issue - if the belt tensioner is spring-loaded and hasn't been replaced it can be a concern.
Thanks for answer. I just checked this morning. steering belt turning without problem. I start thinking that its about steering pump or rack which will cost me a lot. Still i will start with replace belt hopefully it will help.
Dont forget to get the air out of the new pump.
You need a belt tensioner

Mine used to make that noise then i got a new pulley now it makes another noise
I couldn’t hear what to do?

I brought a gates tensioner 2 months ago but it cant be out al ready. Can it?
Yes absolutely. Gates is very hit & miss with the quality of their tensioners. l've seen some Gates tensions new out of the box that were wobbly and couldn't be installed. l think some of them are made in America and some are made in China. OEM is usually the best bet when it comes to tensioner pulley assemblies but even the OEM ones l always repack the bearings before l install them because many times they only come with a minimal amount of grease in the bearings and they usually use the cheapest grease too, which guarantees they won't last as long as they should. l replace the stock grease with a synthetic high temp red grease, then install.
