Alright im sitting here writing straight out of a work shop manual,
Power steering system - Bleeding
1 - Fill the resovoir to the correct level with the fluid of the recommended type and allow to remain undisturbed for at least 2 minutes
2 - Start then engine and run it for 2-3 seconds only, check resovoir and top up as required
3 - Repeat the operations described in the preceding paragraph until fluid levels remain constant
4 - Raise front wheels until wheels are clear above the ground
5 - Start engine and increase revs to approx 1500rpm and gently turn steering wheel stop-to-stop, be sure to check resovoir level
6 - Lower the vehicle to the ground and, with the engine still running, move the vehicle forward sufficiently to obtain full right lock followed by full left lock, recheck fluid level. If the fluid in the resevoir is foamy allow the vehicle to stand for a few minutes with the engine switched off (or if your impatient like me suck the fluid out and put fresh fluid in). The repeat the previous operations. At the same time, check belt tightness and check for a bent or loose pulley. Check also to make sure the power steering hoses are not touching any other part of the vehicle.
Just a few key points they dont tell you when doing this,
holden is gay and still uses imperial so make sure you use the correct size spanners
the high pressure line on the power steering pump is very easily rounded
i done a rebuild well a reseal kit on my pump a while back and it still weeps slightly apparently all commodores have a slight weep
and it may take some time to fully fill the lines and pump with fluid
