REMOVAL & INSTALLATION



See Figures 1 and 2

On some models, an idler pulley assembly type adjustment is used instead of bracket type adjustment

  1. Remove the fan shroud.
  2.  
  3. Unfasten the nut from the center of the pump pulley.
  4.  

Use the drive belt as a brake to keep the pulley from rotating

  1. Withdraw the drive belt.
  2.  
  3. Remove the pulley and the Woodruff key from the pump shaft.
  4.  
  5. Detach the intake and outlet hoses from the pump reservoir.
  6.  

Tie the hose ends up high, so that the fluid cannot flow out of them. Drain or plug the pump to prevent fluid leakage

  1. Remove the bolt from the rear mounting brace.
  2.  
  3. Remove the front bracket bolts and withdraw the pump.
  4.  

To install:
  1. Install the pump and all necessary brackets.
  2.  
  3. Tighten the pump pulley mounting bolt to 25-39 ft. lbs. (34-53 Nm)
  4.  
  5. Adjust the pump drive belt tension. The belt should deflect about 0.4 inches when 22 lbs. pressure is applied midway between the air pump (if so equipped) and the power steering pump.
  6.  
  7. Fill the reservoir with Dexron®II automatic transmission fluid. Bleed the air from the system.

  5. Rotate the steering wheel from lock-to-lock several times. Add fluid as necessary.
  6.  
  7. With the steering wheel turned fully to one lock, crank the starter while watching the fluid level in the reservoir.
  8.  

Disconnect the high tension lead from the coil; do not start the engine. Operate the starter with a remote starter switch or have an assistant turn the switch from inside of the car. Do not run the starter for more than a few seconds without stopping to allow the motor to cool

  1. Repeat Step 4 with the steering wheel turned to the opposite lock.
  2.  
  3. Start the engine. With the engine idling, turn the steering wheel from lock-to-lock two or three times.
  4.  
  5. Lower the front of the car and repeat Step 6.
  6.  
  7. Center the wheel at the midpoint of its travel. Stop the engine.

  9. The fluid level should not have risen more than 0.2 inch (5mm). If it does, repeat Step 7 again.
  10.
