Oil Pump Pressure Test

OIL PUMP PRESSURE TEST CHECKING THE OIL PUMP RELIEF PRESSURE

1. Disconnect the pressure hose from the oil pump, and then connect the special tools.
2. Bleed the air, and then turn the steering wheel several times while the vehicle is not moving so that the temperature of the fluid rises to approximately 50-60° C (122-140° F).
3. Start the engine and idle it at 1,000 ± 100 rpm.
4. Fully close the shut-off valve of the pressure gauge and measure the oil pump relief pressure to confirm that it is within the standard value range.

Standard value : 89 - 95 kg/cm2 (1,265 - 1,351 psi)






CAUTION:
Pressure gauge shut off valve must not remain closed for more than 10 seconds.

5. If it is not within the standard value, replace the oil pump.
6. Remove the special tools, and then tighten the pressure hose to the specified torque.

Tightening Torque:
55 - 65 Nm (5.5- 6.5 kg-m, 39 - 47 lb-ft)


7. Bleed the system.
