When the car is cold (2001 WS6) I get a squeak under the hood. The squeak increases/decreases with engine RPM. I think it's the PS pump.

I used a turkey baster and sucked the old fluid out of the PS Fluid tank and refilled with fresh fluid. Since I never sucked it *all* out, the system stayed pressurized and I didn't suck any air into it. The squeak went away for about a week, then came back.

So my questions:

(1) Is there a way to flush/refill the PS system and get rid of all the old fluid?

(2) What's causing the squeak and how do I fix it?

 

How long has your serpentine belt been on? Most of the time this is the problem, or a belt tensioner thats shot.

Whats with the AD s*& t attachement when I type in serpetine belt??? I'm not linking anything.

 

Try spraying a little belt dressing (sold at most auto parts stores) on the serpentine belt. Sometimes just a little bit of spray will make the squeak go away.

 

Oh yeah ... forgot to mention that the first thing I did to try and solve the problem was to change the belts.
