Welcome to JustAnswer, I'm Neal and I am here to assist you.

Please feel free to ask follow up questions, it is part of the process.


Here is the procedure for removing the entire pump, I only provided this because there is no procedure just for the hose. But this and the diagrams will help. They show the hose attachement at the pump and the steering gear.


At the end is the bleeding procedure.


PREPARATION: Place a drain pan below the pump.

1. Hose, suction.
2. Hose, flexible.
3. Adjust bolt.
4. Belt.
5. Bolt.
6. Pump assembly and pulley.
7. Pulley.
8. Adjust plate.
9. Pump assembly.

1. Pump assembly.
2. Adjust plate. Torque to 56 Nm (41 ft. lbs.).
3. Pulley. Torque to 78 Nm (58 ft. lbs.).
4. Pump assembly and pulley
5. Bolt. Torque to 46 Nm (34 ft. lbs.).
6. Belt.
7. Adjust bolt. After adjusting drive belt tension, tighten bolt to specified torque. Torque to 46 Nm (34 ft. lbs.).
8. Hose, flexible. Torque to 54 Nm (40 ft. lbs.).
9. Hose, suction. Fill and bleed the system.


Bleeding Instructions


When bleeding the system, and any time fluid is added to the power steering system, be sure to use only DEXRON II-E Automatic transmission fluid.
1. Fill the pump fluid reservoir to the proper level and let the fluid settle for at least two minutes.
2. Start the engine and let it run for a few seconds. Do not turn the steering wheel. Then turn the engine off.
3. Add fluid if necessary.
4. Repeat the above procedure until the fluid level remains constant after running the engine.
5. Raise the front end of the vehicle so that the wheels are off the ground.
6. Start the engine. Slowly turn the steering wheel right and left, lightly contacting the wheel stops.
7. Add power steering fluid if necessary.
8. Bring down the vehicle, set the steering wheel at the straight forward position after turning it to its full steer positions 2 or 3 times, and stop the engine.
9. Stop the engine. Check the fluid level and refill as required.
10. If the fluid is extremely foamy, allow the vehicle to stand a few minutes and repeat the above procedure.
11. Inspect as follows:
a. Belt for tightness.
b. Pulley for looseness or damage. The pulley should not wobble with the engine running.
c. Hoses so they are not touching any other parts of the vehicle.
d. Fluid level and fill to the proper level.
