  1. Disconnect the negative battery cable.
  2.  
  3. With the engine cool, partially drain the cooling system.
    NOTE
    The engine struts must be rotated. To prevent shearing of the rubber bushings, loosen the bolts on the engine struts before swinging the struts.

  4.  
  5. Remove the engine strut brace bolts from the upper tie bar and rotate the struts and the braces rearward.
  6.  
  7. Carefully disconnect the throttle body air inlet and adjust the air cleaner assembly for access.
  8.  
  9. Disconnect the radiator inlet hose from the radiator.
  10.  
  11. Disengage the cooling fan shroud retainers, and remove the shroud bolts.
  12.  
  13. Disconnect the transmission oil cooler lines from the retainers at the bottom of the shroud. Disengage the shroud clip from the top of the radiator.
  14.  
  15. Reposition the cooling fan shroud for access and detach the electrical connector.
  16.  
  17. Remove the fan shroud with the electric cooling fans as an assembly.
  18.  

To install:

  1. Attach the cooling fan electrical connector.
  2.  
  3. Install the cooling fan and shroud assembly. Engage the shroud clip at the top of the radiator. Some pressure is needed to completely engage the clip onto the radiator.
  4.  
  5. Connect the transaxle cooler lines to the retainers at the bottom of the fan shroud.
  6.  
  7. Install the shroud bolts and torque to 80 inch lbs. (9 Nm). Install the shroud retainers.
  8.  
  9. Connect the radiator hose to the radiator.
  10.  
  11. Install the air cleaner assembly and air inlet ducts, as required.
  12.  
  13. Rotate the struts and braces forward to their proper position and install the engine strut brace bolts to the upper tie bar.
  14.  
  15. Refill the cooling system with the proper mix of DEX-COOL®and water.
  16.  
  17. Connect the negative battery cable.
  18.  

3.5L (VIN H) Engine
  1. Obtain anti-theft radio codes, as required. Disconnect the negative battery cable.
  2.  
  3. Remove the engine mount strut from the engine mount strut bracket at the upper radiator support. Remove the four bolts from the strut bracket and remove the bracket from the radiator support.
  4.  
  5. Disconnect the cooling fan wiring harness from the engine wiring harness.
  6.  
  7. Remove the cooling fan shroud bolts.
  8.  
  9. Remove the right side radiator bracket.
  10.  
  11. Remove the cooling fan shroud with the electric cooling fan motors.
  12.  

To install:

  1. Install the cooling fan shroud with the electric cooling fan motors to the radiator.
  2.  
  3. Install the right side radiator bracket and tighten the bolt to 80 inch lbs. (9 Nm). Tighten the shroud bolts to 53 inch. lbs. (6 Nm).
  4.  
  5. Connect the cooling fan wiring harness to the engine wiring harness.
  6.  
  7. Install the engine mount strut bracket to the upper radiator support, using care to correctly align the holes. Install the four bolts and tighten to 21 ft. lbs. (28 Nm). Install the strut to the bracket, and insert the through bolt. Tighten the nut to 35 ft. lbs. (48 Nm).
  8.  
  9. Connect the negative battery cable.
  10.  

Except 3.4L (VIN E) And 3.5L Engines

NOTE
Some applications require the fans to be removed with the shroud assembly

  1. Before replacing a fan motor assembly due to noise or vibration complaints, check for dirt or mud buildup on the fan blades. Clean as required.
  2.  
  3. Record any radio anti-theft codes, as applicable. Disconnect the negative battery cable.
