17. Using the 6 mm bolts supplied with the tool, mount
the two uprights to the cylinder head at the end
camshaft holders. The uprights fit as shown.
18. Insert the cross shaft through the bottom hole of
the two uprights.
Select the 7/8 in. diameter short compressor attach-ment and fasten the attachment to the No. 4 hole ofthe lever arm with the speed pin supplied.
Position the piston at TDC and insert an air adaptorinto the spark plug hole. Pump air into the cylinder
to keep the valve closed while compressing springs
and removing the valve keepers.

21. Position the lever arm unde. the cross shaft so thelever is perpendicular to the shaft and the compres-
sor attachment rests on top of the retainer for thespring being compressed. Use the rear position sloton the lever as shown.
NOTE: Put shop towels over the oil passages toprevent the valve keepers from falling into the cylin-der head.
Using a downward motion on the lever arm, com-press the valve spring and remove the keepers fromthe valve stem. Slowly release pressure on thespring.
Repeat step 22 for the other valve in that cylinder.
Remove the valve seals (see page 6-22).

. 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

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.

t
Engine removal is not required for this procedure.
CAUTION: To avoid damaging tho cylinder head, wait
until tho ongino coolant temporature drops bolow 100"F
{38"C) beforo loo36ning the rotainin0 bolts.
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).
@ Do not smoke whils working on tusl
systom, keep opon flame or spark away trom work
area. Drain fuol only inlo an approvod containsr.
4. Disconnect the fuel feed hose.
