Hose - Pressure

Service all power steering hoses with the vehicle raised on a hoist. Cap all open ends of hoses, power steering pump fittings and steering gear ports to prevent the entry of foreign material into the components.

WARNING: POWER STEERING FLUID, ENGINE PARTS AND EXHAUST SYSTEM MAY BE EXTREMELY HOT IF ENGINE HAS BEEN RUNNING. DO NOT START ENGINE WITH ANY LOOSE OR DISCONNECTED HOSES. DO NOT ALLOW HOSES TO TOUCH HOT EXHAUST MANIFOLD OR CATALYST.

REMOVAL

NOTE: To service the power steering pressure hose on this vehicle, the front suspension crossmember and steering gear will need to be lowered away from the body of the vehicle. This is required for access to the power steering hose connections on the side of the steering gear. Refer to Steering Gear Service and Repair for the required procedure for removal of the front suspension crossmember.

1. Raise vehicle on jack stands or centered on a frame contact type hoist. See Hoisting in Maintenance for the required lifting procedure to be used for this vehicle.

CAUTION: When lowering the front suspension crossmember, its installed position on the vehicle's body must be marked on the crossmember before it is lowered. Use the procedure for the removal and replacement of the Steering Gear for the required procedure to locate and lower the crossmember.

2. Lower the front suspension crossmember far enough to gain access to the high and low pressure ports on the steering gear.






3. Disconnect the power steering pressure hose at the power steering gear. Drain power steering fluid from power steering pump and hose through open end of hose.

5. Remove the power steering pressure hose from the pressure fitting on power steering pump.
6. Remove the power steering fluid pressure hose from the vehicle through the bottom rear of the engine compartment.
7. Discard all used O-rings located at ends of power steering pressure hose fittings.

INSTALLATION
1. Install power steering pressure hose in vehicle from bottom of engine compartment using the reverse order of removal.
2. Using a lint free towel, wipe clean all open power steering hose ends and the power steering pump and steering gear ports.
3. Install new O-rings on the power steering pressure hose fittings. Lubricate O-rings using fresh clean power steering fluid.
4. Attach the power steering pressure hose to outlet fitting on the power steering pump. Do not tighten or torque pressure fitting at this time.

CAUTION: Hoses must remain away from exhaust system, vehicle components and unfriendly surfaces causing possible damage to power steering hoses.

5. Correctly route power steering pressure hose avoiding tight bends or kinking of the hose. Install power steering pressure hose routing brackets and attaching bolts on engine.






6. Route power steering pressure hose to pressure port on power steering gear. Install power steering pressure hose, on steering gear and loosely install tube nut into steering gear. Then using a crow foot, tighten the power steering pressure hose tube nut to a torque of 31 Nm (275 inch lbs.).

CAUTION: When installing the front suspension crossmember, it must be installed back in the same location on the vehicle's body as when it was originally installed when the vehicle was built. Review the procedure for installing the steering gear for the required procedure to install and locate crossmember.

7. Raise the front suspension crossmember and steering gear back up into the vehicle.
8. Lower the vehicle.
9. Start the engine and let run for a few seconds. then turn the engine off.
10. Add fluid if necessary. Repeat the above procedure until the fluid level remains constant after running the engine.
11. Raise front wheels of vehicle off the ground.
12. Start the engine. Slowly turn the steering wheel right and left, lightly contacting the wheel stops. Then turn the engine off.
13. Add power steering fluid if necessary.
14. Lower the vehicle and turn the steering wheel slowly from lock to lock.
15. Stop the engine. Check the fluid level and refill as required.
16. If the fluid is extremely foamy, allow the vehicle to stand a few minutes and repeat the above procedure.
17. After hose is installed, check for leaks at all hose connections.
