OIL PUMP PRESSURE CHECK Oil Pump Pressure Check
1. Disconnect the pressure hose from the oil pump connect apressure gauge between the oil pump and pressure hose
2. Bleed the system . Start the engine and turn the steering wheel form lock several times until oil temperature is up to
50°C
3. Run the engine at 1,000 rpm.
4. Close the pressure gauge valve and check oil pressure.
NoticeDo not keep the valve closed for more than 10 seconds.
5. Remove the pressure gauge and connect the pressure hose.
6. Do bleeding procedure. BLEEDING OF POWER STEERING SYSTEM Bleeding of Power Steering System
1. Disconnect the fuel line. Using a starter motor, crank the engine and turn the steering wheel from lock to lock 5 or 6 times. Notice Do bleeding with engine cranking. If bleed with idling, there can be a air contact with oil.
