So I've done a manual conversion and motor swap... But now I've got an air lock in my power steering and it's dead at low revs, it does work when the revs are up... Any tips or tricks?? Tia
Usually jack the wheels clear of the ground, make sure the fluid is full, and move the steering wheel full lock side to side a few times slowly.
The system self bleeds with driving but do some figure 8s in a quiet car park moving from lock to lock will bleed the air out faster. Since you have done this already you should have all the air out and the issue with no PS assistance at low RPM is not any tiny amount of air that might still be in the system. 1. Check the drive belt to ensure it is in good condition and is not slipping on the PS pump pulley. 2. The symptoms you have described (not at all uncommon for failing pumps) are classic symptoms of the power steering pump losing its effectiveness and requiring replacement. It leaks internally from wear and with this wear you will get little or no power assistance at all at idle or at very low RPM. 99% you will be looking at a PS pump replacement here so I recommend you have it checked out by a professional. The problem with hydraulic PS systems is owners never change the PS fluid and internal wear in the pump is accelerated from contaminants never being removed. A typical VZ commodore will have the PS fluid (light pink AT Fluid) dark brown well by now. If the PS fluid has not been changed in the past 4-5 years it needs to be changed now if you want to look after your pump. For the original poster it's too late. The pumps looks to be very much on the way out from the symptoms described.
