Valve Clearance
Adiustment
NOTE:
. Valves should be adjusted cold; at a cylinder head
temperature of less than 100"F (38'C).
. Adjustmsnt is the same for intake and exhaust
vatves.
o After adjusting, retorque the crankshaft pulloy bolt to
177 N.m ( 18.0 kgf.m, 130 lbf.ft).

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.

NOTE:
. Turn the crankshaft pulley so the No. 1 piston is at
top dead center {TDC) before removing the belt (see
page 6-51).
. Inspect the water pump when removed the timing
belt {see page 10-9).

lnstallation
Install the timing belt in the feverse order of removal;
Only key points are described there.
NOTE: Clean the middle cover and lower cover before
installation.
1. Position the crankshaft and the camshaft pulleys as
shown betore installing the timing belt.
A. Set the crankshaft so that the No. 1 piston is at
top dead center {TDC). Align the groove on the
teeth side of the timing belt drive pulley to the V
pointer on the oil pump.
B. Align the TDC marks on intake and exhaust pul-
leys.
2. Install the timing belt tightly in the sequence
shown.
