NOTE
Siphon the power steering fluid from the reservoir before disconnecting the lines to avoid spilling fluid on the secondary timing belt cover. Use shop rags when disconnecting the lines to ensure any remaining fluid does NOT contact the secondary timing belt cover. Power steering fluid can damage the timing belt.

To install:

  1. Connect the power steering fluid lines.
  2.  
  3. Position the power steering pump in the bracket and secure with the retaining bolts. Tighten the bolts to 25 ft. lbs. (34 Nm).
  4.  
  5. Install the serpentine belt.
  6.  
  7. Install the coolant recovery tank.
  8.  
  9. Connect the negative battery cable.
  10.  
  11. Install the air cleaner and duct assembly.
  12.  
  13. Fill and bleed the power steering system.
  14.  
  15. Check the system for leaks, road test and recheck the fluid level.

3.5L (VIN H) Engine



Please note that the power steering pump pulley must be removed to access the pump retaining bolts. Special tools are required to draw the pulley off the pump shaft and to later press the pulley onto the pump shaft. A shop press cannot be used to install the pulley or the pump will be damaged.

  1. Place a drain pan under the vehicle.
  2.  
  3. Remove the coolant surge tank (coolant reservoir).
  4.  
  5. Remove the cosmetic/acoustic engine cover.
  6.  
  7. Remove the accessory drive belt. Please see Section 1.
  8.  
  9. Remove the accessory wiring junction block and set aside.
  10.  
  11. Remove the power steering pump pulley from the pump noting the following:
    1. Use a power steering pump pulley remover. These pullers typically have a ridge that surrounds the collar on the pulley center.
    2.  
    3. Turn the puller screw making sure the center screw is centered in the end of the pump shaft.
    4.  
    5. Draw the pulley from the pump shaft.
    6.  

  12.  
  13. Disconnect the pressure line and return hose from the power steering pump.
  14.  
  15. Unfasten the pump retaining bolts and remove the pump from the engine.
  16.

To install:

  1. Install the pump to the engine. Install the bolts and tighten to 25 ft. lbs. (34 Nm).
  2.  
  3. Connect the power steering return line.
  4.  
  5. Connect the power steering pressure line. Using a "crows foot" adapter and a torque wrench, torque the pressure line fitting to 20 ft. lbs. (27 Nm).
  6.  
  7. Install the power steering pump pulley noting the following.
    1. Use a power steering pump pulley installer such as J 36015, or equivalent. This type of installer threads into the end of the pump shaft. A nut is then turned to press the pulley onto the pump shaft.
    2.  
    3. The face of the pulley hub must be flush with the end of the pump shaft.
    4.  

  8.  


WARNING
Do not attempt to use a shop press to install a pump pulley.

  1. Install the accessory wiring junction block.
  2.  
  3. Install the accessory drive belt, making sure it is properly routed and seated in all pulley grooves.
  4.  
  5. Install the coolant surge tank.
  6.  
  7. Install the engine cover.
  8.  
  9. Fill the power steering system and bleed the system. Check for leaks.
