14. Attach a hose (A) to the end of the flow control valve (B) as shown. Then submerge the flow control valve in a container of power steering fluid (C), and apply compressed air in the hose.
- If air bubbles leak through the valve at less than 98 kPa (1.00 kgf/cm² , 14.2 psi), replace the pump as an assembly. The flow control valve is not available separately.
- If the flow control valve is OK, set it aside for reassembly later.
