How to bleed power steering properly?

[Optical]

I found something in a service manual that says not to run the engine until the system is bled.. Not sure how to bleed it in this case?

Have fitted a new steering rack and lines. No fluid in the system anywhere until now...

Anyone know the 'proper' method?

Fill resivoir, and vac bleed system if you have vac bleeder

Other wise - fill resivoir, let stand for 10min, undo pressure outlet port fitting until fluid flows out and retighten

start engine and IDLE

Top up resivoir again (pump will prob be very noisey but this is OK

After 10 min turn from lock to lock and top up fluid if req'd

Turn engine off and wait 30min (this will release air held in the fluid)

Then finally recheck fluid

Job done

Thanks, I think that is pretty much what I did, but the pump is still making a racket and the steering jerky

Is it possible to blow the pump if you mess up the procedure? Or is it more likely to be a stubborn air bubble in the system somewhere?

I'll have another go at it

It's a b4 remote reservoir pump and spec c rack...

B4 remote res can be a Pri-k

I have found raising the res above the pump a good way to help get air out

also check the hose clamps on that supply hose to the pump, not uncommon for a hose not to be leaking fluid but sucking air in

The pump will settle ( unless you have done big rpm on it with air in the system or big rpm on held on full lock )

Good luck

what a c0ck. ended up changing to the old gc8 pump and it's fine now...

the old pump wasnt sucking fluid up the hose, tried lifting it up but when revert to the same issue when lowered again. must be stuffed...

Did you check those hose clamp fittings? on the feed pipe

i couldnt twist or pull the hose off.. presume it was sealing..

perhaps that o-ring under the top pipe is stuffed. will pick up a new one next time im past the stealers
