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

2. Set the No. 1 piston at top dead center (TDC) (see
page 6-12). "UP" mark on the pulley should be at
the top, and the TDC grooves on the pulley should
align with the TDC groove on timing belt back
cover. TDC mark (painted white) on the crankshaftpulley should align with pointer on the timing belt

Loosen the locknut and turn the adjusting screw
until feeler gauge slides back and forth with a slight
amount of drag.

Rotate the crankshaft 180' counterclockwise(camshaft pulley turns 90'). The "UP" mark should
be on the exhaust side. Adjust valves on No,3 cylin-

Timing Belt
Inspection
1.Remove the cylinder head cover.
o Refer to page 6-33 when installing.
Inspect the timing belt for cracks and oil or coolant
soal(n9.
NOTE:
. Replace the belt if oil or coolant soaked.
. Remove any oil or solvent that gets on the belt.
2.
Rotate pulley
and inspect belt.
After inspecting. retorque the crankshaft pulley bolt
to 177 N'm (18.0 kgf.m, 130 lbnft).
CAUTION: Always adiust iiming belt lension with the
engin€ cold.
NOTE:
. The tensioner is spring-loaded to apply proper ten-
sion to the belt automatically after making the follow-
ing adjustment.
. Alwavs rotate the crankshaft counterclockwise when
viewed from the pulley side. Rotating it clockwise
may result in improper adjustment of the belt ten-
ston.
Remove the cylinder head cover. (Refer to page
6-33 when installing.)
Set the No. I piston at TDC (see page 6-12).
Rotate the crankshaft five to six revolutions to set
the belt.
Set the No. 1 piston at TDC.

Cylinder Head
Wapage
NOTE: lf camshaft-to-holder oil clearances (see page 6
22) arc nol within specification, the head cannot be
resurfaced.
lf camshaft-to-holder oil clearances are within specifica-
tions, check the head for warpage.
lf warpage is less than 0.05 mm (0.002 in) cylinder
head resurfacing is not required.
lf warpage is between 0.05 mm (0.002 in) and 0.2 mm
(0.008 in). resurface cylinder head.
Maximum resurface limit is 0.2 mm (0.008 in) based
on a height of 132.0 mm (5.20 in).
Measure along edges, and 3 ways across center.

lnstallation
Install the cylinder head in the reverse order of removal:
NOTE:
. Always use a new head gasket.
. Cylinder head and cYlinder block surface must be
clean.
. "UP" mark on the camshaft pulleys should be at the
to p.
. Do not use the middle cover and lower cover for stor-
ing removed items.
. Clean the middle cover and lower cover before instal-
lation.
. Replace the washer when damaged or deteriorated
L Cylinder head dowel pins and the oil control orifice
must be aligned.
. When hand'ing a metal gasket, care should be
taken not to fold it or damage the contact surface
of the gasket.
. Clean the oil control orifice when installing,
