Required Special Tools:

•

MB990662: Pressure Gauge

•

MB991548: Power Steering Oil Pressure Gauge Adapter
(Pump Side)

•

MB991549: Power Steering Oil Pressure Gauge Adapter
(Hose Side)

1. Disconnect the pressure hose from the oil pump, and then

connect special tools MB991548, MB990662 and
MB991549.

2. Bleed air, and then turn the steering wheel several times

°

C (122

°

F).

3. The engine should be idling.

4. Disconnect the connector for the oil pressure switch, and

place an ohmmeter.

5. Gradually close the shut-off valve of the pressure gauge and

increase the hydraulic pressure, then check whether or not
the hydraulic pressure that activates the switch is the
standard value.

Standard value: 1.8

−−−−

2.4 MPa (261

−−−−

6. Gradually open the shut-off valve and reduce the hydraulic

pressure; then check whether or not the hydraulic pressure
that deactivates the switch is the standard value.

Standard value: 0.8

−−−−

2.4 MPa (116

−−−−

348 psi)

7. Remove special tools MB991548, MB990662 and

MB991549, and then tighten the pressure hose to the
specified torque.
