Squealing sound on cold temperatures 370z 2010

370zzRed · 10-09-2019, 06:51 PM

Hi there,
I have a issue with my 370 z giving a Loud squealing sound when the engine is cold or accelerating at higher speeds .
Sounds like these - check the video.
https://youtu.be/yGiClVuVFqY
Already took to the dealer and after 3 trips to the dealership and spending $700

it’s still doesn’t go away. The dealer asked me to change steering pump and tensioner which I did and after 2 days it’s back again.

Any help on finding what the exact issue will greatly be appreciated
.

Thanks
Kp

It only does this when cold outside? Mine makes a weird squeal for a second on cold starts when chilly out. Only for a second though. Kinda bothers me but meh. To me your video sounds like a belt? I don't know much though..

Hi Cory,
it happens until the engine is warmed up enough and even when i have A/c on this squealing noise comes back again. which belt are referring to? alternator?

This definitely sounds like a squeaky belt. Take a gander down the front of the engine. Do all the pulleys look lined up? I suppose it could also be a bearing going bad on one of the accessories. Since you replaced the power steering pump and tensioner already, I guess you can eliminate those.

Thanks for the tip. but i have no way to go under engine, no right equipment's .
so, changing the belt will do the trick !

Get a Nissan belt. They always work properly. Other ones are hit or miss.

370zzRed · 10-10-2019, 12:00 PM

is it the accessory belt/drive belt(serpentine) or compressor belt that needs to replaced?

Serpentine, only one belt.

Sorry Guys..i Just checked my receipts from the dealership . they did change the drive belt and looks like that didn't do the trick as well. Any other suggestions.

Did they replace the tensioner and all the pullies? I had to replace mine at 75k miles. They were all raising cain.

370zzRed · 10-10-2019, 02:29 PM

Yes- belt tensioner and power steering pump along with drive belts. not sure this covers any pullies?

Get it checked out by a real mechanic. It sounds like the dealership is just making guesses and changing parts. Doesn't have to be a Nissan or 370Z expert; just a real mechanic.

370zzRed · 10-11-2019, 01:05 PM

I did take it to the other mechanic. Seems like the pulley on the steering pump that was replaced by the dealership was defective.

Defective or the wrong part?

370zzRed · 10-11-2019, 02:04 PM

Well the mechanic said the Pulley comes with steering pump (set) and the one making the squealing noise is coming from the pulley.
