Use this service procedure as a guide for all Chrysler models.

  1. Disconnect the negative battery cable, then, on vehicles equipped with an air bag system, cover the cable terminal with electrical tape to isolate it from accidentally contacting the battery terminal; this is important to prevent the air bag from accidentally being deployed.
  2.  
  3. Disconnect the vapor separator hose from the carburetor/throttle body. If the car has air conditioning, disconnect the 2 wires from the air conditioning clutch cycling switch.
  4.  
  5. Remove the accessory drive belt, as described in Routine Maintenance .
  6.  
  7. Apply the parking brake, block the rear wheels, then raise and safely support the front of the vehicle on jackstands.
  8.  
  9. Place a drain pan under the pump. Disconnect the return hose from the tube on the steering gear and and lower the end of the hose into the pan to drain the fluid from the pump (fluid will continue to drain during the next step).
  10.  
  11. Remove the right side splash shield (this protects the drive belts).
  12.  
  13. Remove the power steering pressure line from the pump. Drain excess power steering fluid from the line.
  14.  
  15. Loosen, but do not remove the unit holding the back of the power steering pump to its mounting bracket. Remove the bolt attaching the pulley side of the power steering pump to the mounting bracket.
  16.  
  17. Lower the front of the vehicle.
  18.  
  19. Remove the bolt retaining the pump in the adjusting slot of the mounting bracket.
  20.  
  21. Remove the pump from the top of the engine compartment, using the following procedure:
    1. Lift the pump out of the mounting bracket.
    2.  
    3. Rotate the pump 90°.
    4.  
    5. Remove the pump from between the engine and dash panel.
    6.  

  22.  
  23. Transfer the required parts from the removed power steering pump to the replacement pump.
  24.  

To install:
  1. Install the power steering pump into the vehicle by sliding it down between the engine and the dash panel, then rotate the pump 90° to install it onto its mounting bracket.
  2.  
  3. Install the pump onto the bracket, being sure that the stud on the backside of the pump is engaged in the slotted bracket hole. Install the pump-to-adjusting slot bolt, but do not tighten the nut or bolt.
  4.  
  5. Raise the front of the vehicle and support it securely on jackstands.
  6.  
  7. Install the bolt attaching the pulley side of the power steering pump to the pump mounting bracket. Do not fully tighten the power steering pump mounting bolts at this time.
  8.  
  9. Install the pump fluid pressure line into the output fitting on the pump. Tighten the fluid line tube nut to 23 ft. lbs. (31 Nm). Before connecting the pressure line to the steering pump, inspect the O-ring on the pressure line for damage; replace it with a new one if required.
  10.  
  11. Install the power steering low pressure return hose onto the steering pump low pressure fitting. Install the hose clamp onto the low pressure hose, being sure that the hose clamp is installed on the hose past the upset bead on the pump tube.
  12.  
  13. Lower the vehicle to the ground and connect the vapor separator and vent hoses to the carburetor/throttle body. Connect the 2 wires to the air conditioning cycling switch, if the car has air conditioning.
  14.  
  15. Install and adjust the accessory drive belt, as described in Routine Maintenance . Tighten the bolt at the power steering pump mounting bracket adjusting slot to 40 ft. lbs. (54 Nm). tighten the pump-to-bracket pivot nut and bolt to 40 ft. lbs. (54 Nm).
  16.  


WARNING
Do not use automatic transmission fluid in the power steering system. Only use Mopar® Power Steering Fluid, or the equivalent.

  1. Fill the pump reservoir with the proper amount of fluid, as described in Routine Maintenance .
  2.  
  3. Remove the tape from the negative battery cable, if necessary, and connect the battery cable.
  4.  
  5. Start the engine and turn the steering wheel several times from stop-to-stop to bleed air from the fluid in the system.
  6.  
  7. Stop the engine, check the fluid level and inspect the system for leaks.
  8.

WARNING
The serpentine drive belt tension must be released before removing the pump. Do not attempt to remove the pump without loosening the belt and releasing the tension because, otherwise, the pump pulley could be damaged.

  1. Remove the serpentine belt. For more details, refer to Routine Maintenance .
  2.  
  3. Place a drain pan under the power steering pump.
  4.  
  5. Install a clamp on the pump fluid return hose to prevent excessive fluid spillage. Disconnect the fluid return hose from the pump. Drain any fluid into the catch pan.
  6.  
  7. Disconnect the high pressure tube fitting from the pump.
  8.  
  9. Remove the pump rear bracket-to-pump bolts.
  10.  
  11. Remove the adjustment bracket-to-rear bracket bolts and the pivot bolt.
  12.  
  13. Remove the power steering pump, the front bracket and the adjustment bracket as a unit from the rear bracket and the engine.
  14.  
  15. If the pump is being replaced with another one, remove the pulley and brackets from the old pump. Before installing the pulley to the new pump, install the front bracket-to-rear bracket bolt to the pump.
  16.  

To install:
  1. If the pulley is not installed on the new pump, position the front bracket and insert the front bracket-to-rear bracket bolt into the pump bore before installing the pulley.
  2.  
  3. If applicable, install the pump pulley.
  4.  
  5. Attach the brackets to the pump, but do not tighten the front bracket-to-rear bracket bolt/nuts at this time.
  6.  
  7. Place the pump with the bracket in the installation position on the engine. Install the adjustment bracket-to-rear bracket bolts, the pivot bolt and the rear bracket-to-pump bolts finger-tight.
  8.  
  9. Tighten the adjustment bracket-to-rear bracket bolts to 30 ft. lbs. (40 Nm) and the pivot bolt finger-tight.
  10.  
  11. Tighten the rear bracket-to-pump bolts finger-tight.
  12.  
  13. Install and adjust the serpentine accessory drive belt, as described in Routine Maintenance .
