Could I have a loose belt? On cold starts, it squeaks anywhere from a few seconds to like a minute.


After searching, i found tsb 10-035, but the videos of people with that issue sound more like a chirp.

 

sounds like a belt and tensioner. see if the tensioner is stable or moves back and forth. my understanding is that it is supposed to stay relatively in the same place and not "bounce" back and forth. the movement in the tensioner allows the belt to slip.

i just had my belt and tensioner replaced and the sound is gone. the new tensioner doesn't seem to move as much as the old one.

 

Would you recommend to replace both the tensioner and belt? How much did you pay for the parts?

 

Also, this falls under powertrain correct? I'm still within the 6 year powertrain warranty so I think I may be able to get the dealership to do it for free.

EDIT: nvm, looks like only the timing belt is covered under warranty.

 

same freaking noise on my car, changed the belt and still happens. gonna change the tensioner/pulley whatever it is soon. lmk if you do it before me what solves it

 

I'm going to try the belt first since it's pretty cheap. If that doesn't work I'll try the tensioner.

 

Mine actually has that same noise. Figured it was just a pulled or belt.. Going to check it out next weekend.

 

i had the dealer replace the tensioner under Acura Care warranty but i had to pay to replace the belt. The noise is gone. my belt was the original and had been on for nearly 7 years so guess it was just time.

 

I just finished changing out my tensioner pulley.
Took me less than 3 minutes to change it out. The squeak I had was identical to your vid btw.

 

^ Did it cure the squeeking noise? Also did you need a pulley puller or just a socket wrench? And what did the tensioner pulley cost? I could use my warranty to get this fixed or if it's that easy i can do it myself.

 

Yes it did cure the squeak

the pulley was 11.52 from oemacuraparts
Used a size 14 socket, and slide a pipe over it and pushed it towards the back of the engine as far as I could.

Then slip the belt off the power steering pump( this should keep it from sliding off the other pulleys.

Then remove the bolt. Just remember its a reverse thread bolt.

Take it off, put new one one and slide belt over it.
Might be intimidating to change but its easier than changing a tire.

 

what part is it exactly? that seems alot cheaper then what i thought

 

My new compressor belt came in the mail last night so I'll install it tonight. I'll let you guys know if the noise goes away. For the past 2 days it has been a lot worse. Now the squeaking persists even when I start driving, and goes away after a few minutes.

 

So I pulled off the old belt, it seems perfectly fine. I spun all the pulleys, and the alternator pulley gives off a slight high pitch noise when spun so I think that's the culprit. Should i just put on the new belt and see what happens?

 

Is there a part# for the alternator pulley? I can't find anything about it...

 

I dont believe you can just replace the pulley on the alternator. You may have to replace the entire assembly.

The problem will be with the bearing holding the pulley in place. if that is the source of your noise.

 

Replacing the drive belt solved this. Thanks guys!
