INSTALLATION

PROCEDURE

1. INSTALL POWER STEERING OIL PRESSURE SWITCH

(a) Install a new O-ring to the power steering oil pressure switch.

(b) Apply a light coat of engine oil to the O-ring of the power steering oil pressure switch.

NOTICE:

• When reusing the power steering oil pressure switch, inspect the O-ring.
• If the O-ring has scratches or cuts, replace the power steering oil pressure switch.

(c) Using SST, install the power steering oil pressure switch. SST: 09922-10010 Torque: without SST : 21 N·m {210 kgf·cm, 15 ft·lbf} with SST : 15 N·m {148 kgf·cm, 11 ft·lbf} HINT: Use a torque wrench with a fulcrum length of 30 cm (11.8 in.). When using a torque wrench with a fulcrum length that is not 30 cm (11.8 in.), calculate the torque specification for the torque wrench and SST based on the "without SST" torque specification (See page ). Make sure SST and the torque wrench are connected in a straight line.

(d) Connect the oil pressure switch connector.

2. INSTALL FAN AND GENERATOR V BELT

(a) Install the fan and generator V belt (See page ).

3. ADD POWER STEERING FLUID

4. BLEED POWER STEERING FLUID

5. INSPECT FOR POWER STEERING FLUID LEAK

6. CHECK FLUID LEVEL

7. INSTALL FRONT FENDER APRON SEAL RH

8. INSTALL FRONT WHEEL

On-vehicle Inspection
