Fluid Pressure Inspection

1. Set the Special Service Tools (SSTs) as shown in the image.





2. Disconnect the pressure pipe from the oil pump, and connect the SSTs.
3. Bleed the air from the system.
4. 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).

CAUTION: If the valve is left closed for more than 5 seconds, the fluid temperature will increase excessively and adversely affect the oil pump.





5. Close the gauge valve completely. 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.

Oil pump fluid pressure:
FS engine (2.0L engine): 7.9 - 8.3 MPa (1138 - 1208 psi)
KL engine (2.5L engine): 8.4 - 8.8 MPa (1209 - 1279 psi)

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.

6. Open the gauge valve fully and increase the engine speed to 1,000-1,500 rpm.





7. 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.

Gear housing fluid pressure:
FS engine (2.0L engine): 7.9 - 8.3 MPa (1138 - 1208 psi)
KL engine (2.5L engine): 8.4 - 8.8 MPa (1209 - 1279 psi)

8. Remove the gauge set. Install and tighten the pressure pipe to the specified torque.

Tightening torque: 24 - 29 Nm (18 - 21 ft. lbs.).

9. Bleed the air from the system.
