so when it's really cold (lower than 30) in morning, my car sounds like it's got a super charger on the passenger side.

I've checked the power steering level, and it's above the low line.

when the car is warm or parked in a heated garage, the noise doesnt happen.

what should i check next?

 

have you had the power steering o-ring recall done? get your VIN and call the dealership that it's been serviced at and find out.

 

If it's an old recall, then it's been done.
I bought the car (2006 base with NAV) 2 years ago as a CPO.

 

^i would still call the dealer and give them your VIN just to make sure. they'll be able to tell you in 2 minutes.

also, check the power steering hose area on the top left hand side of your engine block. do you see any residue or signs of leaking around/underneath?

 

I did check and the hoses look clean. No leaks or any fluid on them.

 

you didn't mention any squealing noise, but i would also check the tension of the P/S belt...

 

it doesnt sounds like a belt noise, but no i never checked the tension.

past experiences with POS trucks lead me to believe this is a Power Steering noise. in fact the noise increases as the steering wheel turns.

Also do you see bubbles in the PS Reservoir ?

 

my acura dealer is fixing this now for me under warranty on my 07 type s fyi

 

nice find, thank you.
i'll replace the o-ring this weekend just as a precaution & check back.

i didnt see any bubbles in the res cup, but i was only checking when the car was off.

 

^^^ yeah try with the car on....i can almost bet you will see the bubbles...

 

check the o-ring as the people above mentioned...

have you changed out the PS fluid yet? if you are getting a noise, maybe the pump is getting starved of fluid? i know you mentioned the level is fine, but i would change out the fluid in case there is debris lodged somewhere... i'm all about trying the cheapest thing first...

 

I replaced the o-ring this morning with the new orange rubber one. Started the car up and it whistled for a quick second then went away. Probably had some air still in there. My original black I-ring was wedged in the pump, and wasn't on the nose of the tubing.

I won't know for sure if the problem is fixed, since we've been having some unusually warm weather lately for January. However, I'm pretty sure my problem is fixed.

Thanks everyone.

 

the new o-ring fixed my problem.

thanks again

 

I just had this problem come up yesterday. I'll be doing this tonight!

 

As Sharksbreath says, I too would call the dealer to run the VIN to insure the recall has been done. Two reasons:

1. The orange O-ring is part of the recall, but yours wasn't done. Not conclusive since many dealerships seem to skip this step;

2. CPO is just as likely a pencil-whipping excercise as an actual inspection and correction of issues. We've seen it time and time again that a CPO inspection is barely worth the paper it's written on.


ymmv

 

Nothing like a 5 minutes, 96 cent fix, is there?
