all,

ive had this squeak noise under the hood.
Sounds like a pulley. It's not the loose belt squeal.
In the last week I have:
replaced the drive belt (dayco from advance auto parts)
replaces the tensioner pulley twice (dayco)

im stumped. It will go away once the engine is warmed up...but still lets out a chirp at times.

Any suggestions on what to look into?
maybe a different pulley? When I put the second pulley on last night, it was fine. No squeaks.

Thanks!

 

I had squeaks and squeals when the car was cold. Brought it to Acura and they replaced drive belt tensioner, and timing belt. No more squeals after

 

it was the tensioner

 

I have just bought a 2013 Acura TL FWD and I do have the same issue. After several visits to Acura dealer where I bought it from,they have replaced the timing belt, tensioner and the water pump but the moment I left the dealership, it started doing that same chirping noise. I gave up and did not go back. I am wondering what is this annoying noise.

Anyone else having this issue with a "chirping or honk sound on cold startup? Doesn't happen when the engine is warmed up.
