lnspection
Remove the cylinder head cover.
. Refer to page 6-78 when installing.
Inspect the timing belt for cracks and oil or coolant
soaking.
NOTE:
. Replace the belt if oil or coolant soaked.
. Remove any oil or solvent that gets onthe b€lt.
Rotate pulleyand inspect b6lt.
After inspecting. retorque the crankshaft pulley bolt
to 177 N.m (18.0 kgf.m, 130 lbf.ft).
Tension Adjustment
CAUTION: Always adlust timing bslt tsnsion with th6
engine cold.
NOTE:
. The tensioner is spring-loaded to apply proper ten-
sion to the belt automatically after making the follow-
ing adjustment.
a Alwavs rotate the crankshaft counterclockwise when
viewed trom the pulley side. Rotating it clockwise
may result in improper adjustment of the belt ten-
sion.
Remove the cylinder head cover. (Refer to page 6-
78 when installing.)
Set the No. 1 piston at TDC (see page 6-51).
Rotate the crankshaft 5-6 revolutions to set the belt.
