  1. Remove the drive belt. If the pulley is to be removed, do so now.

To install:
  1. Make sure the bracket-to-engine bolts are tight and install the pump to the brackets. Tighten the retaining bolts after installing the drive belt to the correct tension.
  2.  
  3. If the pulley has been removed, install it and tighten the nut securely. Bend the lock tab over the nut. Later model pulleys have to pressed on and off. Install the heat protector, if so equipped.
  4.  
  5. Install the drive belt and adjust to a tension of 22 lbs. (30 N) at a deflection of 0.28-0.39 in. (7.11-9.91mm) at the top center of the belt. Torque the pump bolts to 21 ft. lbs. (30 Nm) and hold the belt tension.
  6.  
  7. Connect the pressure line and torque the banjo fitting nut to 13 ft. lbs. (18 Nm). Connect the return lines and fill the reservoir with ATF+3 automatic transmission fluid.

BELT ADJUSTMENT



  1. Press the V-belt by applying pressure of 22 lbs. (30 N) at the center of the belt.
  2.  
  3. Measure the deflection to confirm that it is within the standard range.
    1. Colt, standard value: 0.2-0.4 in. (6-9mm).
    2.  
    3. 1990-91 Vista, standard value: 0.3-0.4 in. (7-10mm).
    4.  
    5. 1992-93 Vista, standard value: 0.4-0.5 in. (9-12mm).

SYSTEM BLEEDING



  1. The reservoir should be full of ATF+3 automatic transmission fluid.
  2.  
  3. Raise the vehicle and support it safely.
  4.  
  5. Turn the steering wheel fully to the right and left until no air bubbles appear in the fluid. Maintain the reservoir level.
  6.  
  7. Lower the vehicle and with the engine idling, turn the wheels fully to the right and left. Stop the engine.
  8.  
  9. Install a tube from the bleeder screw on the steering gear box or rack, to the reservoir.
  10.  
  11. Start the engine, turn the steering wheel fully to the left and loosen the bleeder screw.
  12.  
  13. Repeat the procedure until no air bubbles pass through the tube.
  14.  
  15. Tighten the bleeder screw and remove the tube. Refill the reservoir as needed and check that no further bubbles are present in the fluid. An abrupt rise in the fluid level after stopping the engine is a sign of incomplete bleeding. This will cause noise from the pump or control valve.
