R33 Gtst - Noisy Power Steering On Startup

[chilzzi]

Hi all,

wondering if anyone has anything similar occur....

Basically on startup, the power steering is very noisy but then goes away once the car has warmed up.

The power steering pump has had a full reco around 18 months ago. Before then, the noise was constant.

Any help would be greatly appreciated.

cheers

Is the fluid aerated/bubbly in the reservoir?

100% its p/s? Dropped the belt and rechecked ?

Would suck if say it was an idler or tensioner pulley and just sounded like it was coming from p/s pump area then let go

Not sure, it's just really strange that on a cold morning startup the car is fine, no noises. If right then I do a dry steer, the loud noise starts. Once the car has warmed up a bit, it's all perfect and quiet!!! What the!!

Pulling this up from a year ago but did you ever fix this problem....mine started doing this exact same thing this morning

this was the symptom of mine as the power steering pump was getting on - noisy when cold and dry steering, then would go away.

it will gradually get worse if it is indeed the PS pump.

bottom line is you can leave them for a while without any trouble.

Mine started having a noticeable effect on the slow speed steering when the car was still warming up until I did anything (replaced the PS pump).

good luck!

You can try replacing the fluid to help with cold temp steering. As fluid gets old and sludgey and is thicker than normal when cold. This means it isn't lubing the system as well. Draining the fluid and replacing it with fresh fluid can help.

Yes that fixed it! Got it completely flushed and new oil. Runs as it should now!

Sorry new fluid!!

I have to get around to doing it to my Commodore at some point (when I could be bothered, along with finding the cause of the slight misfire it has). had a leaky pump for ages and had put some stuff in it that was supposed to slow/stop leaks. Basically it was a thick fluid. I finally got a new pump but didn't completely flush the system (just topped it up really), so on cold mornings the steering has a bit of a notch just off straight. Once it warms up it's fine. I did some googling and that's when I found out about flushing the system (which made sense, since the fluid is thinner when warm, and on really cold mornings it was much worse, to a point where on a sub zero morning I had no power steering the first time I tried to turn the wheel).

My car did the same thing at one stage. Just filled it up with fresh and away it went.
