1990 740GL: Air-bound Power Steering pump??

    Hello,

    My power steering started to die at low RPMs, so I tried changing the
    fluid. Didn't help. So, I got a used pump at a junkyard, and
    installed it.

    This pump doesn't seem to work at all (my old pump was pushing fluid
    very well when I replaced the fluid).

    Before I return this pump to the junk yard as dead, I want to make
    sure that there isn't any way the pump could become "air bound." In
    other words, I'm wondering if this pump is ok, but there is so much
    air in the system that it can't push any fluid. Is there a way to
    bleed the system and get some fluid into this dry pump? Or should a
    working pump take care of this automatically?

    Thanks,
    Jay R.

  2. I am not sure about Volvo but on other cars I have read that you are
    supposed to jack the front tires off the ground and turn from lock to
    lock half a dozen times with no load on the system. Good luck.

    Problem resolved. I installed a bad junkyard pump initially.
    Replacement worked fine and sucked down nearly a quart of ATF.
