I replaced the PS control valve and steel lines to the power cylinder. After purging the air in system countless times, the power steering pump (or belt?) is groaning and the steering wheel behaves a bit jittery and harder while turning the wheel when cold. After warm up it works fine, but then there's a sawing-whine noise which disappears when turning the wheel off dead center.
The lines are correct in that the most forward line is connected from the control valve to the power cylinder as is the rear line to rear line. I used Type F ATF. The belt was tightened and appears in good condition. While I was turning the wheels lock to lock to purge air, I revved the engine a bit to make turning easier and some light smoke came from the belt area.
I would have thought I fried the belt if it didn't look fine. The noise is definitely coming from the pump area. Could I have damaged the pump? Temperature affects operation.
