REMOVAL & INSTALLATION



3.0L Engines
EXCEPT PREMIER AND MONACO

See Figures 1 through 15

Since these engines utilize timing belts, which are run dry, rather than timing chains, the oil seal is not located in the timing belt covers. Thus, this procedure does not include the replacement of the oil seal, which is located in the oil pump. For the oil seal replacement procedure refer to the oil pump procedures found earlier in this section.

  1. Disconnect the negative battery cable.
  2.  
  3. If equipped with air conditioning, loosen the adjustment pulley locknut, turn the screw counterclockwise to reduce the drive belt tension and remove the belt.
  4.  
  5. To remove the serpentine drive belt, insert a 1 / 2 in. breaker bar in to the square hole of the tensioner pulley, rotate it counterclockwise to reduce the drive belt tension and remove the belt.

  1. Raise and safely support the vehicle. Remove the right inner fender splash shield.
  2.  
  3. Remove the crankshaft pulley bolt and the pulley/damper assembly from the crankshaft.
  4.  
  5. Lower the vehicle and place a floor jack under the engine to support it. Use a piece of wood between the floor jack and the engine to help prevent damage to the engine.
  6.  
  7. Mark the support assembly in relation to the engine bracket if the assembly is to be used again. Separate the front engine mount insulator from the bracket. Raise the engine slightly and remove the mount bracket.
  8.  
  9. Remove the timing belt cover bolts and the upper and lower covers from the engine.
  10.  

To install:
  1. Install the lower and then the upper timing belt covers to the engine block. Since there are four different length bolts used to hold the covers on, make certain that the correct bolts go where they belong (refer to the illustration). Tighten all mounting bolts to 10 ft. lbs. (14 Nm).
  2.  
  3. Install the engine mount bracket to the engine block. Tighten the mounting bolts to 40 ft. lbs. (54 Nm).
  4.  
  5. Install the right engine support assembly to the engine mount bracket. Insert the bolt through both brackets and tighten the nuts to 75 ft. lbs. (102 Nm).
  6.  
  7. Lower the engine slowly until the right engine support assembly just touches the engine frame bracket. Install the two attaching bolts and tighten to 50 ft. lbs. (68 Nm).
  8.  
  9. Double check that all bracket bolts are installed and tightened, then slowly let the engine down until the load has been taken off of the floor jack.
  10.  
  11. Install the crankshaft drive pulleys and damper by following the preceding procedures.
  12.  
  13. Raise and support the front of the vehicle on jackstands and install the right inner splash shield.
  14.  
  15. Lower the vehicle.
  16.  
  17. Install the steering pump, the steering pump/alternator belt tensioner, and the A/C compressor to the engine.
  18.  
  19. Install the accessory drive belts according to the adjustment procedures in General Information & Maintenance . The serpentine belt will automatically adjust its own tension and the A/C compressor drive belt should be tightened with the A/C drive belt tensioner until only 5 / 16 in. (8mm) deflection is apparent between the crankshaft pulley and the A/C compressor pulley.
  20.  
  21. Connect the negative battery cable.
