Belt pulley noise?

I recently paid attention to the noise when I rolled down my windows. The noise seems to be coming from the belt pulleys. It's not a squeak or squeal but it's a rolling swoosh sound. I have a Cai but the sound I am talking about is not from the Cai either. I checked for play in the pulleys and sprayed water to see if the noise goes away but it does not. Belt tension seems okay to me. Can some please tell me if the sound is normal and your car make the same noise or is this something that needs to be addressed.

My 2014 v6 has been making some squeaking type noises from the belt area as well lately. I'm hoping it's just from condensation/weather but if it keeps up I'm taking her in. It seems to only be at start up and if it is there it goes away after a few mins of idle.


Love my Mustang but damn these are noisy little hotrods. lol

It might be the tension pulley. The sound surely come from somewhere that side. Its not too difficult to do it yourself right? Just open the bolt and replace the bearing?

I'll use the stethoscope metho to check which pulley is the noise coming from though maybe this weekend.

There was a squeak in the belt area. As time wine on it got worse. Sometimes you wouldn't hear it until higher rpms where it really started to squeal. Dealer wouldn't do anything about it the first time because they "couldn't" replicate it. I insisted that I take them for a drive and the tech who rode with me heard it and diagnosed it as the tensioner pulley. They replaced it under warranty. This was in October and I've already heard the squeaking start again on the new one. Pretty sure it's a piece of junk part. I wish someone made after market billet ones for our cars.

Tension pulley is an easy job. Now I'm basing this on my 07' Acura TL. Try to find a YouTube of it and if there isn't one please video yours.

Sounds like my deal, thanks! Now hopefully someone recognizes the OPs issue. Maybe he can post a video for sound purposes?

Hawkstang the video for the sound is embedded in my first post. It's a whine.

My bad, I didnt get much sleep last night. I listened a couple times and cant hear a "whine"... Maybe a raspy ticking though.

Can you hear it while driving? Is it at idle only? When I briefly had a CAI on my Mustang it amplified all engine bay noise, but I doubt that has anything to do with yours.

No problem happens to the best of us. It does not sound that way while driving. It's at idle and it increases if I accelerate a little. In the video I accelerate to about 2k rpm in the beginning. It's not too bad as of now but it's a start. It's kind of swooshy metallic rolling whine. I don't think this sound is normal. It definitely comes from the pulleys though. It's not the Cai for sure.

Id take Josh's advice and do a little google research into the tension pulley. Mine is only on idle as well but it's more of a squeak. Best of luck and let us know when you solve it!

I replaced the tensioner on mine last year...literally a 30 minute job and the tensioner is only about $20-$30. Might as well replace the belt too while you're at it.

Do you need any special torque tools?

I didn't use one, but I'm sure there are torque specs for the two bolts that hold the tensioner to the block.

If this is the correct title, "Accessory drive belt tensioner bolts", the manual says, "97 in lbs".

The weather was finally good enough for me to work on it today. I removed the belt (5 min job) and checked all the pulleys. The tensioner pulley seems to have gone bad. I started the car without the belt and the engine was silent with no crazy noises. There is quite a bit of play in it so I ordered one at local ford. They did not have one so I will get on Tuesday. Costs about 37$. Not sure if it's the entire tensioner or just the pulley. Will keep you guys posted.

Is it ok to run your engine without the belt?


I have a feeling I will be going through this sooner than later as well so if you feel like doing a write up when finished that would be awesome.

Not for long the belt spins the alternator and water pump which you need for your car to run, you can run it for a couple min with out one but any longer you run the risk of over heating

Hawkstang as he said you should not run it for a long time. A min or two to just check everything is fine. It will give you a charging system error on the dash in a min but that's okay.

Here is a link on how to replace serpentine belt.

I'll put up a write up once I change the pulley. Should be simple I guess the entire tensioner seems to be on 2 bolts.

I replaced the tensioner pulley today and the noise went away. Now, the car is quiet again. It is an extremely easy job and i was done with everything within 20 min.

Attached is the pdf on how to do it.

To add to the mix, I vaguely remember reading that Ford put out a TSB on the tensioner for some model years, so it might even be a fix-for-free item if you have a good dealer.

Mine does this in the cooler temperature as well. Never had an issue and had it inspected there was nothing wrong as far as they said.

Mine also makes a noise upon start up in cooler temperatures, but after a few minutes it subsides.
Had Ford look at it and of coarse they said its totally normal lol.

Sure thing, I had problems on previous cars with the belts and was worried about it on this car as well. Another thing you may have noticed but shouldn't worry about is valve clicking in super cold weather. Just idle for a little extra time to allow the oil to circulate and the gaskets to warm up.

10-4 on that. It didn't take me long to figure out that Mustangs aren't very winter friendly as far as noises go. Anything under 30 degrees and I let her warm up for 5 mins before driving. On top of that I watch the transmission temp and don't get on her until it's in the green.
