air in pas system?

[complaints69]

Have read through some posts about pas as mine is whining away good and propper.
I don't drive it much (only at weekends really) and today i heard this noise.

I read on one post that air could be causing this noise. How does the air get in there?

I done the whoosh earlier, and the fluid level was on the min mark, the engine was warmed up after a 2 mile drive, does that mean that the pas fluid is warm too? I am thinking no, but maybe wrong.

I did notice too that there were quite a few small air bubbles floating on the top of the fluid when checking the level.

What are other peoples experiences with this subject?

bleed the system and make sure theres enough fluid in there:

There are no min or max levels. just a cold and warm level, so if its been used a bit and is on the lower one you could top it up a bit. low level does make it whine, but it doesnt sound hugely low.

mine whined a bit when i changed the fluid, had plenty in it, soon stopped tho once it had run a bit

i will top it up a bit, what fluid do i need, where from, and what does it cost?

dex2 PAS fluid 1L from vauxhall, ?under a tenner?

[Rusty_CallyT]

dextron 2 or 3, halfords or anywhere else will sell it, price.. well whatevers on the shelf, dont think it will be more than £10/L tho

got some dexron2 from vaux, £6.99.

The only querey i have is that it does say TRANSMISSION OIL on the label, and looks a bit red through the level indicator on the bottle. Is this definateley the right stuff?

PAS fluid and auto transmission fluid are the same thing

well just topped it up in the end, the old fluid still looks ok, and it was too cold to stay out for too long. BRRRRRRR!
