Service Procedure
Replace the High Pressure Power Steering Hose1. Open the hood
2. Remove the air filter lid, air intake resonator and throttle body air box as an assembly.
3. Using a suction gun, remove the power steering fluid from the power steering fluid reservoir.
NOTE:
Clean the power steering reservoir cap and surrounding area to prevent dirt from entering the system when the cap is removed.
4. Using an 18 mm line wrench, disconnect the pressure hose at the steering gear housing (Figure 1).
NOTE:
If the pressure hose nut will not come loose from the steering gear
housing, cut the pressure hose off at the nut with a mini-tube cutter and use a 6 point deep-well socket to remove the nut.
5. Remove the EGR transducer from the back of the engine cylinder head to gain access to the power steering hose routing bracket (Figure 2).
6. Remove the fasteners that hold the power steering pressure hose routing brackets to the engine cylinder head (Figure 2).
7. Using an appropriate hoist, lift the
vehicle.
8. Remove the right front wheel-well housing plastic splash shield (Figure 3).
9. Remove and discard the plastic tie strap on the power steering pressure hose near the back of the pump (Figure 4).
10. Remove the pressure hose nut or banjo bolt from the power steering pump.
11. Push the disconnected pressure hose up to clear the power steering drive belt.
12. Lower the vehicle from the hoist.
13. Remove and discard the old power steering pressure hose from the vehicle.
NOTE:
Verify that the old o-rings came off with the pressure hose. If the o-rings are not on the pressure hose, verify that they are not stuck in the rack and pinion housing and/or the power steering pump fitting.
14. Place the new power steering pressure hose into position.
15. Lift the vehicle on the hoist.
16. Connect the power steering pressure hose to the power steering pump outlet port.
^ Vehicles with a hose nut (without variable-assist steering) tighten to 23 ft. lbs. (31 N.m).
^ Vehicles with a banjo bolt (variable assist steering) tighten to 35 ft.lbs (47 N.m).
17. Install a new plastic tie strap that holds the power steering fluid supply hose to the power steering pressure hose (Figure 4).
18. Install the right front wheel-well housing plastic splash shield (Figure 3).
19. Lower the vehicle from the hoist.
20. Install the fasteners that hold the power steering pressure hose routing bracket to the engine cylinder head (Figure 2). Tighten the fasteners to 21 ft. lbs. (28 N.m).
21. Install the EGR transducer to the back of the engine cylinder head.
22. Connect the power steering pressure hose to the steering gear housing. Tighten the fasteners to 23 ft. lbs. (31 N.m).
23. Install the air filter lid, air intake resonator and throttle body air box as an assembly.
24. Bleed the air from the power steering system using the following procedure:
a. Fill the power steering reservoir to the correct fluid level.
b. Start the engine and let it run for 5 seconds and then turn off the engine.
c. Add power steering fluid to the system as required.
d. Repeat Steps a through c until the fluid level remains constant after running the engine.
e. Raise the front wheels off the ground.
f. Start the engine and slowly turn the steering wheel right and left several times until lightly contacting the wheel stops. Then turn off the engine.
g. Add power steering fluid if necessary.
h. Lower the vehicle.
i. Start the engine and turn the steering wheel slowly from lock to lock and then turn off the engine.
j. Add power steering fluid if necessary.
NOTE:
If the power steering fluid is extremely foamy, allow it to stabilize for a few minutes and then check the fluid level.
25. Inspect high pressure hose connections to ensure that there are no leaks.
