Timing Belt Installation

NOTE: The following procedure is for installation of a used timing belt. If you are installing a new belt, refer to the TIMING BELT REPLACEMENT PROCEDURE .
  1. Clean the timing belt pulleys, the timing belt guide plate, and the upper and lower covers.
  2. Set the timing belt drive pulley to top dead center (TDC) by aligning the TDC mark (A) on the tooth of the timing belt drive pulley with the pointer (B) on the oil pump.

  4. Loosely install the idler pulley with a new idler pulley bolt so the pulley can move but does not come off.
  5. If the auto-tensioner has extended and the timing belt cannot be installed, do the timing belt replacement procedure (see TIMING BELT REPLACEMENT  ).
  6. Install the timing belt in a counterclockwise sequence starting with the drive pulley. Take care not to damage the timing belt during installation:
    1. Drive pulley (A)
    2. Idler pulley (B)
    3. Front camshaft pulley (C)
    4. Water pump pulley (D)
    5. Rear camshaft pulley (E)
    6. Adjusting pulley (F)

  13. Install the crankshaft pulley (see CRANKSHAFT PULLEY REMOVAL AND INSTALLATION  ).
  14. Rotate the crankshaft pulley about six turns clockwise so the timing belt positions itself on the pulleys.
  15. Turn the crankshaft pulley so its white mark (A) lines up with the pointer (B).
    NOTE: The other pointer (C) is not used.

  16. Check the camshaft pulley marks.
    NOTE: If the marks are not aligned, rotate the crankshaft 360 degrees, and recheck the camshaft pulley mark:
    • If the camshaft pulley marks are at TDC, go to step 17.
    • If the camshaft pulley marks are not at TDC, remove the timing belt and repeat steps  2 through  16.
