Thread: 4L V8 power steering pump

There is a bleed screw on top of the p/S Box, it should have a nipple cover, remove that let the engine idle and loosen the nipple, slightly, watch the bubbling fluid drain and keep filling your reservoir with new fluid, once you get a steady stream of straight fluid only then tighten the bleed nipple .
It is important you don't turn the wheel whilst you do this procedure.

Note: The idea of some is to fill it up and turn your steering wheel from lock to lock to purge air is not the correct way according to RAVE

Cheers mate, advise much appreciated as I would have gone the option you suggested was incorrect according to RAVE. Any tips on the actual removal of the pump?

apologies I should have written get a mate to turn from lock to lock slowly whilst the bleed screw is open

What I did whan I replaced the pump (thanks to InWC), was to fill and while the belt was off spin by hand whuch circulated the fluid without pressure. After getting the fluid to circulate back to the reservoir, which seems to push much of the air before it, I then followed rave. Doing this I didn't have fluid pouring everywhere, for the cost of genuine fluid which seems to be what everyone recommends I lost less than 50mls.

Absolute pearla! Great advise, cheers Clubagreenie

Didn't notice your post re removal of pump. Remove A/C and ACE pumps (if fitted) only by memory. If you HAVE ACE, while you can there's a thick hose which is the pumps suction line from the reservoir. These are no longer available as a replacement (at least I couldn't find one). The hose is a different diameter at each end but you can make a replacement from a straight brass reducer and elbow and 3 pieces of hose.

Looking straight down at the reservoir on the right, you can see the tee bolt clamp where the replacement hose is fitted.

This hose leads to the reducer where it changes size to match the fitting on the back of the ACE pump. Then you have another short length of hose to an elbow which turns towards the ACE pump. You can just see the next clamp at the elbow to the right of the corrugated air inlet hose above.


Above you can see the two clamps of the reducer and first clamp of the elbow and finally the clamp on the rear of the pump.

Everything is available from Pirtek (Enzed don't have the same range of brassware) and should set you back around $30- including hose. It's not under pressure so you don't need to overtighten the clamp especially on the back of the pump as it's only cast alloy.

Cheers man, much appreciated
