•
Timing pulley, keeping stretched the side
opposite to the water pump, observing the
engine RPM direction, if using the same belt.
•
Align the camshaft timing pulley mark with the
timing pulley rear cover mark.
•
Align the crankshaft timing pulley mark with the
oil pump case flange mark, on the no. 1 cylinder
combustion stroke.
• Adjust the belt Tensioner; with a 6-mm Allen
wrench, so as to keep steady the Tensioner
shaft, loosen the Tensioner shaft attaching bolt,
use a 13-mm combination wrench until it
remains steady.
With a 6-mm Allen wrench, turn counterclockwise
the Tensioner shaft up to the NEW marking point (±
1 mm) (detail B). The needle can move from the
right side up to the final adjusting position. Tighten
the bolt with a 13-mm combination wrench; for old
timing belts, follow the same procedure, but
adjusting the belt in the “USED” position.
This change is suggested due to the old belt
presenting a different course of action regarding the
new belt.
