PAS refill/refresh

[tooSavvy]

My PAS fluid is original @8yr old.

 

Any suggestions as to maximizing %age replaced [easily] by just emptying/refilling bottle a few times vs. disconnecting a gland/pipe and simultaneously draining/refilling the whole lot with engine on....

Let the pipes rust out, replace them, run new fluid through and accept that the weird froth on top is normal

 

Oh wait no, that's my MX5, don't do that

AFAIK the best way to do it is the fiddly disconnect pipe/run engine method. Apparently it also works for automatic gearboxes but you need sufficient brave pills to do that.

Another alternative PS method is to replace the pump as not only will it horribly stain the drive, you'll have Cologne au Dexron for weeks after.

[tooSavvy]

Agreed to all above

 

Ta!

This is the method I've been looking at for my Mk1 Mondeo, but only if I can get proper access to a ramp, I don't think my neighbours would appreciate this on the Queen's highway.

May I suggest that if it works well, just leave it? I bet if I took the conscientious measure of replacing the fluid the dirt that was holding the seals together would be flushed away and the whole lot would shit it's breeks on the B816 at Castlecary*

 

*may be drawn from actual experience.

I echo the just leave it approach. My fluid was black, so I siphoned the little tank dry, then topped it up with fluid/conditioner. A few days later, boom, stiff steering (the 2 are probably not linked but it happened...)

 

The fluid is still dark, just not quite as jet black, I should really flush it the proper way as above but not until I;ve got the steering working properly again

I am tempted to do the simple way and use a syringe to empty the reservoir and refill, or take the pipe off the bottom and drain, which won't change it all, so rather like an auto box oil change.  Doesn't change it all but do it reasonably frequently and hopefully it'll be enough.

[Guest Lord Sward]

Aye.  That'd be my approach.  Gently does it.

Does PAS fluid ever need changing? Apart from when something has self destructed and the system needs cleaning thru.

 

I've never done it on anything I've ever owned.

[Junkman]

Why on earth would anyone ever bother with PAS fluid???

 

Get a fucking life, for God's sake!

[sierraman]

Where do you end with the change this change that mentality. Put it this way I've took cars 150k on the old fluid.

[Junkman]

I've never changed PAS fluid in my life.

And I have dug '61 Imperials out of the desert they call a State in those colonies.

I looked at mine cos it looked like used deisel oil with the consistency of water.
