Recently my power steering fluid tank has been leaking a little, so after reading through some previous posts I decided to change the O-ring at the base of the tank.

Took the tank off the PAS pump and left it off over-night as I had to get the new O-ring and some replacement fluid.

Put it all back together last night....topped up fluid to correct level, started car, worked steering from lock-to-lock, topped up level again etc...until level was correct.

All was good until about five miles down the road......a dreadful whining noise started coming from the PAS pump and on investigation the fluid seemed more like a froth (boiling ?).

Is there just some air left in the system ??

How do I get the air out / bleed the power steering ?

Have I totally mashed it ??

any ideas / help would be much appreciated....

Can anyone help ???? Please ??

If it is air, there must be some way of getting it out....

What sort of fluid??? It does say Dexron II on the reservoir lid. Did you use it.. It may just still be airlocked, as the bottle does seem to fill very slowly.

Used Dexron III as recommended in other threads. I know it says Dexron II on the cap but I presume III is the newer version and is OK to use.

Is there any other way to bleed the air out apart from starting the car and turning from lock to lock ???

Steve,

when you are turning it lock to lock - make sure the cap is OFF the header tank - that should clear it.

My steering fluid always boils over on the track - another little job to do......

Had a very similar thing recently.

There is not anyway of bleeding the pump. Already tried that.
You could try and overfill the bootle to try and push out the air leak if there is one.

If it is frothing the fluid, it sounds like an air leak so the O'ring you replaced it with might not be sealing properly.

When you took off the bottle did you also take off the base plate?
There is another O'ring under this base plate.

Is the ring your replaced it with a Subaru one?

Try to look where the fluid is coming from.

There is no other way to get the air out than to keep on turning the steering lock to lock, it helps if you hold the engine at 3000 rpm while you are doing it, when we fitted a 22b steering rack to my car it took nearly 30 mins to get 95% of the air out, the rest worked itself out over the following week.

I've got a problem with fluid pissing out over the top of the resevoir even when the caps on. Is this caused by trapped air too???

Thanks to all those who replied......it's fixed now !!

I replaced the RED 0-ring with a BLACK one. Apparently, the black rubber o-ring was "eaten" by the mineral based power steering fluid. This resulted in the ring splitting and creating a gap for air to enter the power steering pump - hence the constant noise and not being able to bleed air out.

Having put the proper RED o-ring back in place, everything is once again normal.....no harm done.

thanks again....
