Hey guys first of all let me say thank you to all that are helping me. I have a 06 TL about 70k miles and make this noise I took a video below and this only happens when its cold and when I start up the car but go away when I'm driving or isnt as loud and piercing one of my friends (sunny201) saw air bubbles in my power steering reservoir tank and said something about being the pump anyway lmk what it could be if you need more pics or video it can be done Thanks

 

PS pump o-ring TSB...search for it

 

I had that problem before. The sound would whine when u turn the steering wheel. Eventually after the car warms up the sound is gone.

replace the o-ring. U can do it urself or have dealer replace it free of charge

 

If it makes more noise when you turn the steering wheel, it's definitely the PS o-ring. It's shrunk in the cold weather and allowing air to be sucked into the pump. $1 fix. I've done 3 of them so far for family.

#13 in diagram. Part number 91345-RDA-A01. Local Honda & Acura Dealer WILL have it in stock (Honda is cheaper):

 

Wow guys thanks for you help I will do the some research ps o-ring and try to do to get it done

 

All you do is remove that #18 bolt and pull the plastic fitting #3 out. Remove the old black o-ring and install the new orange o-ring. Bolt it back up and go for a drive. Once all the air works out of the system, the noise will be gone.

The only tricky part is picking the right wrench to undo that bolt. It's in an odd spot. I think you just need a 10mm box-end. A typical craftsman will do, as long as it has the slightly angled handle. I can't remember cause it's been a while.

 

ok nice i am ordering the o-ring from acuraoemparts.com i ordered 3 just in case so i will take a crack at it when they come in thans man

 

ok so rings came in today I probably will do it on sunday before the AFC & NFC games where exactly is that #18 bolt the pic honestly got me lost oh and a side not this is my first DIY beside installing my led light which was a joke lol
Thanks
