Valve Clearance
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.

the lever arm with the speed pin supplied.
Position the piston at TDC and insert an air adaptor
into th€ spark plug hole. Pump air into the cylinder
to keep the valv€ closed while cgmpressing springs
and removing the valve keepers.
Position the lever arm under the cross shaft so the
lever is psrpendicular to the shEft and ths compres-
sor attachment rests on toD of the rstainer for th€
spring being compressed. Use the rear position slot
on the lever as shown.
NOTE: Put shop towels over the oil passag€s to

Timing Belt
Inspection
Remove the cylinder head cover.
. Reler to page 6-3'l when installing.
Inspect the timing belt for cracks and oil or coolant
soaking.
NOTE:
. Replace the belt if oil or coolant soaked.
. Rsmove any oil or solvent that gets on the belt.
Rotate pulley
and inspscr bell.
After inspecting, retorque the crankshaft pulley bolt
to 177 N'm ('18.0 kgf'm, 130 lbt'ft).
Tension Adjustment
CAUTION: Always Ediust timing belt tonsion with tho
cngin. cold.
NOTE:
. The tensionet is spring-loaded to apply proper ten-
sion to the belt automaticallv after making the follow-
ing adjustment.
. Always rotate the crankshaft counterclockwise when
viewed trom the pulley side Rotating it clockwise
may result in improper adjustment ot the belt ten-
sion.
Remove the cylinder head cover. (Refer to page
6-31 when installing.)
Set the No. 1 piston at TDC (see page 6-12).

Only key points are described here,
NOTE: Cl€an the middle cover and lower cover beforeinstallation.
L Position the crankshaft and th€ camshaft pulleys asshown before installing the timing belt.
A. Set the crankshaft so that the No. 1 oiston is at
top dead center (TDC). Align the g.oovo on the
t€eth side of the timing belt d.ive pulley to the Opointer on the oil pump.
L Align the TDC marks on intake and exhaust pul-
tevs,
NOTE: To set the camshafts at TDC position for
No. 1 piston, align the holes in the camshafts
with the holes in No. l camshaft holders andinsert 5,0 mm pin punches in the holes.

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).
