@@EasyFixShaun Unfortunately, I had both idler and tensioner pulley, replaced both dead easy for 22 bucks and half an hour of my time, problem solved. And after like a month or two my ac pulley started screeching, couldn't change the AC myself thanks to ac gas so it ended being like 1k€ 🥲
Oof! Sorry to hear that. Sometimes just the bearing/clutch assembly on the end of the ac compressor can be replaced if there is room to do it. Glad you got it fixed up though 🍻
Gotcha, you could start the engine a couple minutes to see which pully is the hottest, maybe it's the culprit as it experiences the most friction that makes the most heat. Am I right?
@@satochinakamoto6129 Some pulleys run hotter normally such as alternator pulley vs AC pulley. Even the tensioner pulley will run little hotter than idler pulley. Ymmv
Excellent! Dont forget to verify bad parts before replacing parts. It's a pain to remove belt just for testing. But it is usually less expensive because you have a better chance at getting the right parts 😀
Sounds great. It was in this car. The idlers are easy as long as you can access them. Some engine pulleys areas are super tight and become the bottle neck of the repair. Good luck with your project 😀
Im having the high squeak too but I sprayed a lubricant in the alternator pulley and the noise stopped immediately but obviously came back after it dried out a few mins later. Would i be wrong to assume its my alternator pulley then right, any help would be appreciated ?
Hard to say. You could be right. I like to disconnect the battery, remove belt, and spin all pulleys by hand. Usually the bad one(s) will jump out at you 😀
@@EasyFixShaun yes, actually, i said "im going to start with this first", change them both, and the sound went off. It was a nice practical lesson imo.
Might need a safe listening device to test some pulleys. Or you can always remove the battery terminals and remove the belt and hand spin all pulleys. The Bad ones will usually jump out at you 😃
Did you spin the other pulleys by chance when the belt was off? Usually the alternator would be most suspect after the idlers and tensioner. But any of the pulleys on the accessory belt can cause the sound.
Yeesh. I would have changed that AC pulley pre-emptively but i understand customers sometimes just want bare minimum. Or its your own car and easy enough to change later lol
Yup. I agree. Although that a/c bearing was clearly dry and noisy. I have seen them last years and years. I think its because of the larger size of the bearing. It should be replaced for best results though.
Not a bad idea at all but more expensive. The main culprits are usually idlers and tensioner pulleys. From experience i've learned the other pulleys usually last years even though they weren't perfect. I wanted to take care of the obvious ones first and keep an eye on the other pulleys. I will let you know how it goes 😃
Ah! The old screw driver stethoscope : My dad who is 88 now taught me that when i was a wee lad : at 62 I have an 8 year old, when I did that he thought I was crazy till I had him put his ear up to it ! That is one of the things that my 4.2 Ford V-6 needed ....interestingly enough, I did the water on the belt trick first and it made it go away for a few minutes, but it came back , so I figured I better look further ....
So I have a whining noise coming from my engine bay for months now... I took it to two mechanics, at one of their shops they checked all the belts, they said they took all the belts off and run the engine and it was still making that noise. They said it might be coming from the engine, like from the chain inside the engine.... But of course they don't work on engines so who knows.. Car has been running fine for months but now I'm not so sure. Gonna check the pullies myself.
Process of elimination is a good method to make sure all accessories bearings on the belt spin silently with the belt removed. If nothing turns up, you could have an idler pulley or tensioner pulley bad on your timing belt system. Some water pumps also run on the timing belt. So it is very plausible depending on what type of system you have for timing. Some vehicles have timing chains with water pumps running on them also. Exploratory surgery on the timing belt or chain system may be needed to inspect and find the culprit if everything else checks ok with the accessories and no other related causes seem to be the issue 😃😃
✅ means ok. One was the culprit. The other was spinning really freely and not making noise. I decided to just replace both since i was in there. I figure the other one could go bad sooner rather than later also 😀
The a/c pulley sound isn't ideal. It has some wear on it and is dry. But it's tight and sounds good otherwise spinning on the belt. It could need repair in the future. They often will sound like that for quite a while before they fail. I think that is because they are larger in diameter. But theres no guarantee. They could fail at anytime once they sound like that.
while it is probably working, this is very dangerous lol. the way i do it is: i remove the belt and i use zip tie connected to the crank and the pulley im suspecting to make the sound, that way its much safer and youre 100% sure you find the culprit
I am facing a similar issue with VW, When the car is fully occupied and generates noise, the service center technicians are unable to identify the issue. On idle condition there no any noise even if accelerate
This was an awesome video! Thank you! My 04 Mustang is making that whining sound idling. I’m a tech/mma guy, not a mechanic but learning. Thank you again!
Thank you! Learning is fun and you should never stop! Soak it all up like a sponge. I wish youtube was a thing when I was young. That would have been amazing.
I changed the water pump and timing belt but now my car won’t start. Had a mechanic realign the timing and he couldn’t get my car to start, Can anyone tell me what I did wrong?
Hard to say, Mechanic should be able to get to the bottom of that. Probably a sensor left disconnected or damaged possibly. Hard to say from here. Let us know what you find out 😃
The power steering pump probably runs on the belt. When the belt came off that could explain steering assist being gone. Find the reason the belt came off and repair. You may be able to re-use the belt if it looks ok 😀
replaced all idler pulleys and belt tensioner. now when i start the engine i hear a clicking noise for a few minutes and it stops after the engine is warm. 2005 4runner v6 2wd
Sometimes there can be a tricky noise like that to track down. I like to hand spin pulleys with the belt off and battery disconnected. I am usually surprised at the noise some pulleys will make and it's a great test for me. I would suggest rechecking everything and see what you come up with. Sometimes the alternator bearings or ac compressor pulley can be the problem too so check those 😃
@@EasyFixShaun well after my belt exploded i can definitely say that was the problem. damn shop gave me a belt that ripped after only an year. just replaced it myself after getting a tow from my insurance. everything is running smooth now 😂
My car kind of has that whine with a high pitched squeel to it on idle and acceleration and as soon as i got over 10 mph the noise goes away. Car runs smooth on the highway, would i be safe to drive it a few more weeks
Hard to know from here exactly. I have seen a lot of belts last a long time that squeak at start up and then go away after driving, similar to what you are describing for your one symptom. Sounds like you have multiple issues though so be careful. You may have an idler bearing of some sort ready to let loose. Let me know how it goes 😃
@@EasyFixShaun hey finally got it fixed. First shop told me it was a ac compressor going bad but my ac is still working, took it to another guy that several people have mentioned before to me being a good mechanic he solved the noise. Had valve & intake manifold gaskets that were leaking oil on the belts so he fixed those to solve the leaking. I had those done in fall by another shop that didn’t do a good job so I could tell it was still leaking bad when he showed me under the car. He cleaned the belts & changed the power steering belt that was causing the noise. He also did an oil change. Car runs smoother and no more noise thank god.
How long can you drive with a noise like this before it goes?? Is this something that can put you on the side of the road in a week?? I just noticed this exact noise about 5 days ago and i have a hunting trip tomorrow 😬😬. 5 hour drive, obviously i will get it in to the mechanic asa soon as i get back but is it ok to drive for a week with this issue?? Thanks man
@@EasyFixShaun Lol it was actually my water pump which I literally just had changed. Just got home from picking my truck up lol. Didn't wanna take any chances. Appreciate ya though my friend
thanks for the video sir I have a question I have toyota yaris cross 2021 1.5 engine petrol (26000 kilometers now) all maintenance has been done regularly by the toyota service.transmission fluid also had been changed I have a problem no one can solve it The car is Ukrainen we came to Turkey (because of the war) when there is little bit high hill ,the car makes tooo much loud exhaust sound (seems like mustang car sound)but car moves like a turtle.Even full loaded semi trucks can go easily when i drive on a regular road sometimes there is no sound but when the weather is hot in turkey that loud exhoust sound starts again it happens more if we are 2 or 4 people in the car and if there is a little high hill 10-15 percent uphill or even on straight road i took 5 times to dealership they said car has no problem what might be the problem when weather is hot and when we are 2 or 4 people i get that sound all the time thank you so much
Hi no problem. Could be many things. Maybe a map sensor problem. It controls the fuel amount. You could try a new one and see if that helps. Those symptoms also make me think of a possible exhaust restriction under higher engine loads. I would start off by removing the upstream oxygen sensor for testing when you can duplicate the problem. It will be really load. If it runs perfect with it upstream sensor removed from the exhaust pipe (other than the sound) you most likely have a restrictive catalytic converter since you effectively bypassed it. Make sure the hot exhaust coming out isn't going to damage anything. Try those two things and see if that helps 😀
Anything that will transmit the sound safely would work. The longer the better to keep your body and clothing away from the spinning parts for safety 😃🔧
