    Then submerge the valve in a container of power steering fluid or solvent, and blow on the hose. If air bubbles leak through the valve, replace or repair it as follows.

  4. 9
    Unscrew the seat in the top end of the valve, and remove any shims, the relief check ball, relief valve and relief valve spring.
  5. 10
    Clean all the parts in solvent, dry them off, then re-assemble and re-test the valve.

    Install the control valve in the reverse order of removal.
