Removal & Installation



  1. Disconnect the negative battery cable.
  2.  
  3. Remove the clips and right side splash-shield.
  4.  
  5. Remove the lower alternator cover plate.
  6.  
  7. Remove the alternator drive belt and if equipped, the A/C drive belt.
    NOTE
    It is not necessary to remove the crankshaft timing sprocket bolt (center bolt) to remove the crankshaft pulley.

  8.  
  9. Remove the crankshaft pulley bolts and crankshaft pulley.
  10.  
  11. Remove the water pump pulley.
  12.  
  13. Remove the retaining bolts and nut from the timing belt outside cover.
  14.  
  15. Remove the timing belt outside cover.
  16.  
  17. Turn the crankshaft to align the timing marks. The mark on the crankshaft sprocket should align with the arrow mark on the oil pump housing. The mark on the camshaft sprocket should align with the V mark on the timing belt inner cover or cylinder head cover.
  18.  
  19. If the timing belt is to be reused, mark the direction of rotation on the belt.
  20.  
  21. Remove the timing belt tensioner, tensioner plate, tensioner spring, spring damper and timing belt.
    NOTE
    Never turn the camshaft or crankshaft independently after the timing belt has been removed. Interference may occur between the pistons and valves, and parts may be damaged.

  22.  
  23. Inspect the timing belt for wear or cracks, and replace as necessary. Check the tensioner for smooth rotation.
  24.  
  25. If the timing belt sprockets are to be removed, proceed as follows:
    1. Using a 0.39 in. (10mm) rod inserted into the camshaft, hold the camshaft and remove the retaining bolt and camshaft sprocket.
      WARNING
      Be careful not to damage the cylinder head or cylinder head cover mating surfaces. Place a clean shop cloth between the rod and cylinder head. Do not bump the rod hard against the cylinder head when loosening the bolt.

    2.  
    3. If equipped with a manual transaxle, lock the crankshaft in position by inserting a suitable flat-bladed tool into the hole in the bottom of the bell housing to engage the flywheel teeth.
    4.  
    5. If equipped with an automatic transaxle, lock the crankshaft in position by inserting a suitable flat-bladed tool between the flywheel teeth and against the engine block.
    6.  
    7. Remove the crankshaft sprocket bolt and crankshaft sprocket.

To install:

  1. If the timing belt sprockets were removed, proceed as follows:
    1. Install the crankshaft sprocket, aligning the keyway. Lock the crankshaft in place and tighten the crankshaft sprocket bolt to 81 ft. lbs. (110 Nm).
    2.  
    3. Install the camshaft sprocket and retaining bolt. Lock the camshaft in place using the rod, and tighten the bolt to 44 ft. lbs. (60 Nm). Remove the locking rod.
    4.  

  2.  
  3. Install the tensioner plate to the tensioner.
  4.  
  5. Insert the lug of the tensioner plate into the hole of the tensioner.
  6.  
  7. Install the tensioner, tensioner plate and spring. Do not fully tighten the tensioner bolt and stud at this time.
  8.  
  9. Move the tensioner plate in a counterclockwise direction. This should cause the tensioner to move in the same direction. If it does not, remove the tensioner and tensioner plate, and reinsert the tensioner plate lug in the timing plate tensioner hole.
  10.  
  11. Check that the camshaft timing marks are aligned. If not, align the two marks by turning the camshaft.
  12.  
  13. Check that the punch mark on the crankshaft timing belt sprocket is aligned with the arrow mark on the oil pump case. If not, align the two marks by turning the crankshaft.
  14.  
  15. With the timing marks aligned, install the timing belt on the two sprockets. If the old belt is being reused, be sure to install it running in the same direction of original rotation.
  16.  
  17. Install the tensioner spring and spring damper. Turn the timing belt two rotations clockwise after installing the tensioner spring and damper to remove any belt slack. Tighten the tensioner stud to 8 ft. lbs. (11 Nm), then the tensioner bolt to 20 ft. lbs. (27 Nm).
    NOTE
    Confirm that both sets of timing marks are aligned properly.

  18.  
  19. Using a new seal, install the timing belt cover and tighten the bolts and nut to 97 inch lbs. (11 Nm).
  20.  
  21. Install the crankshaft pulley. Fit the keyway on the pulley to the crankshaft timing belt sprocket and tighten the bolts to 8-12 ft. lbs. (11-16 Nm).
  22.  
  23. Install the alternator drive belt, if equipped, A/C drive belt.
  24.  
  25. Install the lower alternator cover plate. Tighten the bolts to 89 inch lbs. (10 Nm).
  26.  
  27. Install the right side splash-shield and clips.
  28.  
  29. Connect the negative battery cable.
  30.  
  31. Run the engine. Check for leaks.
  32.
