To install:
  1. If, for any reason, the engine was disturbed, the camshafts moved or the sprockets replaced, perform the following procedure:

Make sure the correct notch in the pulley is indexed to the lower cylinder block.

  1. Position the crankshaft just prior to Top Dead Center (TDC).
  2. If not already done, locate and remove the plug bolt by the Crankshaft Position (CKP) sensor (refer to the illustration) and install the TDC timing peg.
  3. Rotate the crankshaft clockwise against the TDC peg.

Installation of the alignment tool into the exhaust camshaft may require the camshafts to be rotated clockwise.

  1. Install the camshaft alignment tool on the back of the camshafts.
  2. Install the timing belt and engage the timing belt tensioner tab into the upper timing cover backplate.

A 3/8 inch drive, 10mm, 2 inch torque adapter offset is required to tighten the tensioner bolt.

  1. Using a 6mm Allen wrench, adjust the tensioner until the index marks are aligned and tighten the bolt to 17-20 ft. lbs. (22-28 Nm).
  2. Rotate the crankshaft clockwise against the TDC alignment peg, then remove the camshaft alignment tool.
  3. Remove the TDC peg tool and install the plug bolt.
  4. Install the timing and valve covers.
  5. Install the water pump pulley and the splash shield.
  6. Install the spark plugs.

If the engine or the camshaft were not disturbed in any way, or the sprockets were not removed, perform the following procedure:
