3. INSPECT FLOW CONTROL VALVE
(a) Coat the valve with power steering fluid and check that it
falls smoothly into the valve hole by its own weight.
(b) Check the valve for leakage. Close one of the holes and
apply 392±490 kPa (4±5 kgf/cm
2, 57±71 psi) of com-
pressed air into the opposite side, and confirm that air
does not come out from the end holes.
If necessary, replace the valve with one having the same letter
as inscribed on the front housing.
