Disconnect the pressure pipe from the steering gear, and connect the SSTs.
Tightening torque

29.4-44.1 N.m

{3.00-4.49 kgf.m, 21.7-32.5 ft.lbf}
Bleed the air from the system.
Open the gauge valve fully.
Start the engine and turn the steering wheel fully left and right to raise the fluid temperature to 50-60 °C {122-140 °F}.

Increase the engine speed to 1,000-1,500 rpm and measure the fluid pressure generated by the oil pump.
- If the pressure is not within the specification, repair or replace the oil pump component.
CAUTION:
- If the valve is left closed for more than 5 seconds, the fluid temperature will rise excessively and adversely affect the oil pump.
Oil pump fluid pressure

8.23-8.92 MPa

{84.0-90.9 kgf/cm ² , 1,200-1,290 psi}
Open the gauge valve fully and increase the engine speed to 1,000-1,500 rpm.

Turn the steering wheel fully to the left and right, then measure the fluid pressure generated at the gear housing.
- If the pressure is not within the specification, repair or replace the steering gear component.
CAUTION:
- If the steering wheel is kept in the fully turned position for more than 5 seconds, the fluid temperature will rise excessively and adversely affect the oil pump.
Gear housing fluid pressure

8.23-8.92 MPa

{84.0-90.9 kgf/cm ² , 1,200-1,290 psi}
Remove the SSTs . Install and tighten the pressure pipe to the specified torque.
