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.

NOTE: It is recommended for easy installation that the
belt be secured with a double clip or equivalent clip after
it is installed the timing belt to each pulley.
