Removal Procedure

WARNING: This page is about a different variant/trim than selected.
    NOTE: Failure to follow the described timing belt inspection and maintenance may result in a broken timing belt and cause severe engine damage.
  1. Visually inspect the timing belt for cracks and wear. If cracks or wear are present, do not reuse the belt.
  2. Remove the timing belt cover. Refer to Timing Belt Cover Replacement .
  3. Remove the crankshaft balancer. Refer to Crankshaft Balancer Replacement .

  4. Rotate the crankshaft in the engine rotational direction, clockwise using the J 42098  until the #1 cylinder is at Top Dead Center (TDC) on the compression stroke. See Special Tools and Equipment .

    The reference marks on the camshaft gears should be aligned with the corresponding notches on the rear timing belt cover, as well as the mark on the crankshaft sprocket and oil pump housing.

  5. Rotate the crankshaft counter clockwise using the J 42098  until 60 degrees Before Top Dead Center (BTDC). See Special Tools and Equipment .

    The 60 degrees BTDC point can be identified by the index mark on the oil pump cover.

    IMPORTANT: Ensure the moveable lever is positioned toward the crankshaft.
  6. Install the J 42069-10 to the crankshaft sprocket with the knurled bolt.
  7. Rotate the crankshaft in the engine rotational direction, clockwise using the J 42098  until the lever of the J 42069-10 firmly contacts the water pump pulley flange. See Special Tools and Equipment .

    The #1 cylinder is at TDC at this point.

  8. Secure the moveable lever of the tool to the water pump pulley flange.
    IMPORTANT: Ensure that the crankshaft is not 180 degrees off TDC.
    The reference marks on the camshaft gears should be aligned with the corresponding notches on the rear timing belt cover at this point. If they are not aligned, the engine is 180 degrees off.

  9. Install the J 42069-1 and the J 42069-2 to the camshaft gears.

    If the J 42069-1 or the J 42069-2 do not fit into the teeth of the camshaft gears, it may be necessary to loosen the upper idler pulley and turn the eccentric or camshaft gears until the tool can be inserted.

  10. Loosen the timing belt tensioner nut.
  11. Loosen the upper idler pulley bolt.
  12. Remove the lower idler pulley bolt.
  13. Remove the lower idler pulley and spacer.
  14. Remove the J 42069-10 from the crankshaft sprocket.
    15. NOTE: After timing belt is removed, never turn camshaft and crankshaft independently. If turned, interference may occur among pistons and valves, and parts related to pistons and valves may be damaged.
    IMPORTANT: Do not remove J 42069-1 and the J 42069-2 while the belt is removed.
  15. Remove the timing belt.
