7. Connect the pump outlet hose (A) to the P/S joint adapter (hose).
8. Open the shut-off valve (A) fully.
9. Start the engine, and let it idle.
10. Turn the steering wheel from lock-to-lock several times to warm the fluid to operating temperature at 158 °F (70°C).
11. Measure steady-state fluid pressure while the engine is idling. If the pump is in good condition, the gauge should be no more than 1,470 kPa (15
kgf/cm2, 213 psi). If it reads higher, check for:
^
Clogged or deformed pump outlet or return line between the pump and gearbox.
^
Clogged valve body unit.
12. Raise the engine speed to 3,000 rpm, and measure the fluid pressure. If the pump is in good condition, the gauge should read at least 1,470 kPa
(15 kgf/cm2, 213 psi). If it reads higher, repair or replace the pump.
13. Lower the engine speed, and let it idle. Close the shut-off valve gradually until the pressure gauge needle is stable. Read the pressure.
NOTICE; Do not keep the shut-off valve closed more than 5 seconds or the pump could be damaged by overheating.
14. Immediately open the shut-off valve fully. If the pump is in good condition, the gauge should read at least 7,850 - 8,550 kPa (80 - 87 kgf/cm2,
1,140 - 1,240 psi). A low reading means pump output is too low for full assist. Repair or replace the pump.
15. Reinstall all removed parts.
