Fig. Fig. 3: The 2.2L Turbo III engines use 5 pulley-to-crankshaft flange mounting bolts, which are also tightened to 23 ft. lbs. (31 Nm)

The 2.2L and 2.5L Except Premier engines do not utilize crankshaft mounted dampers. The 2.2L Turbo II and 2.5L engines utilize a dual-balance shaft system which mounts under the engine to control engine vibrations. This procedure will describe crankshaft pulley removal and installation.

  1. Disconnect the negative (-) battery cable.
  2.  
  3. Remove the accessory drive belts, as described in Routine Maintenance .
  4.  
  5. Apply the parking brake, block the rear wheels, then raise and safely support the front of the vehicle on jackstands.
  6.  
  7. Remove the right inner splash shield from the wheel well.
  8.  
  9. Loosen and remove the retaining bolts holding the pulley to the crankshaft. Pull the pulley off of the crankshaft flange.
  10.  

To install:
  1. Slide the pulley back onto the crankshaft and secure in place with the attaching bolts. Tighten the bolts in a crisscross (star-shaped) pattern to 23 ft. lbs. (31 Nm).
  2.  
  3. Install the right inner splash shield in the wheel well.
  4.  
  5. Lower the vehicle to the ground and remove the wheel blocks.
  6.  
  7. Install the accessory drive belts. Refer to Routine Maintenance for the procedures on tightening the drive belts for correct tension.
  8.  
  9. Connect the negative (-) battery cable.

Fig. Fig. 4: Use a bolt-on damper removal/installation tool to draw the damper off of the crankshaft

  1. Disconnect the negative (-) battery cable.
  2.  
  3. Remove the accessory drive belts, as described in Routine Maintenance .
  4.  
  5. Remove the cooling fan shroud, as described under the radiator removal and installation procedures in this section.
  6.  
  7. Apply the parking brake, block the rear wheels, then raise and safely support the front of the vehicle on jackstands.
  8.  
  9. Remove the center damper retaining bolt and washer. It may be necessary to hold the engine to keep it from turning while loosening the center bolt. This can be done by having an assistant hold the flywheel stable with a wrench, a breaker bar or even a C-clamp.
  10.  
  11. Using a suitable torsional crankshaft damper removal/installation tool (bolt-on type), remove the torsional damper from the crankshaft.
  12.  
  13. After the torsional damper has been removed, make certain to locate the crankshaft key. This will be needed upon installation.
  14.  

To install:
  1. Install the crankshaft key into the groove on the crankshaft.
  2.  
  3. Install the torsional damper onto the crankshaft after aligning the slot in the damper with the key on the crankshaft. Lightly tap the damper onto the crankshaft with a rubber or plastic mallet. Tap the center of the damper, not the outer edges.
  4.  
  5. After the damper has been installed slightly onto the crankshaft, install the center bolt and washer and slowly tighten the bolt until the torsional damper seats itself completely onto the crankshaft.
  6.  
  7. Tighten the center bolt to 80 ft. lbs. (108 Nm) while your assistant holds the engine from turning.
  8.  
  9. Lower the vehicle to the ground and remove the wheel blocks.
  10.  
  11. Install the accessory drive belts. Refer to Routine Maintenance for the procedures on tightening the drive belts for correct tension.
  12.  
  13. Connect the negative (-) battery cable.
  14.  

2.6L Engine

Since the 2.6L engine utilizes 2 counter-rotating auxiliary shafts to dampen the vibrations of the crankshaft, they are not equipped with a crankshaft mounted damper. This procedure will cover removal and installation of the crankshaft pulley.

  1. Disconnect the negative (-) battery cable.
  2.  
  3. Remove the accessory drive belts, as described in Routine Maintenance .
  4.  
  5. Apply the parking brake, block the rear wheels, then raise and safely support the front of the vehicle on jackstands.
  6.  
  7. Remove the right inner splash shield from the wheel well.
  8.  
  9. Remove the center crankshaft pulley retaining bolt. It may be necessary to have an assistant hold the engine to keep the crankshaft from turning while loosening the center bolt. This can be done by having an assistant hold the flywheel/flexplate stable with a wrench, a breaker bar or even a C-clamp.
  10.  
  11. Pull the pulley off of the crankshaft.
  12.  
  13. After the pulley is removed, make certain to locate the crankshaft key (if equipped). This key will be needed upon installation.
  14.  

To install:
  1. Install the crankshaft key into the groove on the crankshaft.
  2.  
  3. Slide the crankshaft pulley onto the crankshaft after aligning the slot in the pulley with the key on the crankshaft. Lightly tap the pulley onto the crankshaft with a rubber or plastic mallet. Tap the center of the pulley, not the outer edges.
  4.  
  5. After the pulley is installed slightly onto the crankshaft, install the center bolt and slowly tighten the bolt until the pulley seats itself completely onto the crankshaft.
  6.  
  7. Tighten the center bolt to 87 ft. lbs. (118 Nm) while your assistant holds the engine from turning.
  8.  
  9. Install the right inner splash shield in the wheel well.
  10.  
  11. Lower the vehicle to the ground and remove the wheel blocks.
  12.  
  13. Install the accessory drive belts. Refer to Routine Maintenance for the procedures on tightening the drive belts for correct tension.
