Power Steering Fluid — Inspection of Fluid Pressure (continued)
N-11prose procedureOil pump fluid pressure spec value 1,138—1.208 psi printed verbatim (the second figure's separator appears as a period in the scan). High pressure hose torque differs between B6 DOHC and K8 DOHC.
Inspection of fluid pressure (continued)
- 6Close 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 below specification, replace the oil pump assembly.Do not left the valve stay closed for more than 5 seconds. The increase in fluid temperature will damage the power steering oil pump.Oil pump fluid pressure: 7,846—8,335 kPa {80.0—80.5 kgf/cm2, 1,138—1.208 psi}
- 7Open the gauge valve fully again and increase the engine speed to 1,000—1,500 rpm.Never hold the steering wheel to the extreme left or right for more than five seconds. This could damage power steering oil pump.
- 8Turn the steering wheel fully to the left and right and measure the fluid pressure generated by the gear housing. If the pressure is below specification, repair or replace the steering gear assembly.Gear housing fluid pressure: 7,846—8,335 kPa {80.0—80.5 kgf/cm2, 1,138—1.208 psi}
- 9Remove the gauge set. Install the high pressure hose and tighten the joint nut to the specified torque.Tightening torque: B6 DOHC: 16—23 N·m {1.6—2.4 kgf·m, 12—17 ft·lbf}; K8 DOHC: 24—35 N·m {2.4—3.6 kgf·m, 18—26 ft·lbf}
- 10Bleed the air from the system. (Refer to page N-8.)
