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 kgim, 130 lbf.ft).
1. Remove cylinder head cover.
ADJUSTING SCREW LOCATIONS:
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 crankshaft
pulley should align with pointer on the timing belt
tower cover.

NOTE:
. Inspect the timing belt before removing the cylinder
neao.
. Turn the crankshaft pulley so that the No. 1 piston is
at top dead center (TDCI (page 6-12).
. Mark all emissions hoses before disconnecting them.. Anti-theft radios have a coded theft protection circuit.
Be sure to get the customer's code number before.- Disconnecting the battery.- Removing the No. 32 (7.5 A) fuse irom the under-
hood fuse/relay box.- Removing the radio.
After service, reconnect oower to the radio and turn it
on.
When the word "CODE" is displayed, enter the cus-
tomer's 5-digit code to restore radio operation.
1. Disconnect the negative terminalfrom the battery.
2. Drain the engine coolant (see page 10-5).
. Remove the radiator cap to speed draining.
3. Relieve fuel pressure (see Section 1 1).

Installthe cylinder head in the reverse order of removal:
NOTE:
. Always use a new head gasket.
. Cylinder head and cylinder block surface must be
ctean.
. "UP" mark on the timing belt pulleys should be at the
top.
. Do not use the middle cover and lower cover for stor-
ing items disassembled.
. Clean the middle cover and lower cover before instal-
lation.
. Replace the washer when damaged or deteriorated.'1. Cylinder head dowel pins and the oil control orifice
must be aligned,
NOTE:
. When handling a metal gasket, care should be
taken not to told it or damage the contact surface
of the gasket.
. Clean the oil control orifice when installing.

NOTE: lf camshaft-to-holder oil clearances (see page 6-
21) are not within specitication, 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 resurtacing 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
