5. Align the alignment mark (white line) on the timing
belt (1) with the alignment mark on the LH bank
camshaft drive gear pulley (2).
When aligning the timing marks, use a wrench to
turn the camshaft drive gear pulley, then set the
timing mark between timing belt and camshaft
drive gear pulley and put the timing belt on the
camshaft drive gear pulley.
Secure the belt with a double clip or equivalent
clip.
