Title: PAS sytem. Refill and bleed advice
Post by: Webby the Bear on 26 June 2013, 06:30:45
Hey gays, hope you're all good.

How do you guys do the above? I fitted a new PAS pump to my mate's Hyundai Coupe and when I fitted the new part and refilled the system it sounded like SHIIIIIIIIIIIIIITE!!!!!! Even at idle it was screeching and clunking  :o

I went about bleeding the way I thought it was to be done..... turn steering lock to lock a few times with the lid off the fluid reservoir and I left it to idle.

the noise was that bad I actually thought something was seriously wrong  :o luckily the job is a 5 minute one so I popped the old one back on and that made a little bit of noise initially and then settled down fine (apart from still exhibiting the reason for it's replacement of it screeching at full left lock).

Anyway I was thinking about this and i'm wondering if I simply didn't bleed it well enough instead of condemning the eBay part as junk. What do you think?

Remember as always i'm still learning so your methods baby-fied please :)

nice one mate. I thought so. its also odd that putting the old one back responded to my method of bleeding - that's why I was so quick to condemn the eBay part.

ive asked him to bring it over again as I want to be doubly sure so ill pop the ebay part on again and have a play.

I believe these can be ''remanufactured'' somewhat so I may take it apart and see if I can repack the bearings.

oh the joys of auto repair  ::)

lmao. yeah i'm fairly sure it cant do that.

ok two questions that are on my mind....

1.) when I get the new part (gonna get one from a motor factors for him) would it be sensible to prime it with PAS fluid so its not dry on initial start up?

2.) someone on a Hyundai forum mentioned an air bleed nipple on the rack itself.  ??? i'd never heard of this but I suppose it makes sense. anyone else heard of this on any car?

it is possible to have a bleed screw in rack-have a look-what you could do is pour oil into pump-first-messy but fun :y

lol yeah it did get messy. it missed the rags i'd put down and went on the road  :-[

Ill have a look for a bleed screw but even if there is one it should have bled out using lock to lock method, right?
