Lift and Support Points
Lift and Safety Stands
ffi When heaw rear components such as suspension, Iuel tank, spare tire and tailgate are to b€ lemoved, place
!iiii-'rn"t r""igtrt in the trunk before hoisting. When substantial weight is removed flom the lear ot the vehicle, the
center of gravity may change and can cause the vehicle to tip fotward on the hoist'
NOTE: Since each tire/wheel assembly weighs approximately 30 lbs (14 kg), placing the front wheels in the cargo area can
assist with weight distribution.
1. Place the lift blocks as shown.
2. Raise the hoist a few inches (centimeters), and rock the vehicle to be sure it is firmly supported.
3. Raise the hoist to full height, and inspect the lift points for solid support'
NOTE: Use the same suppon points to support the vehicle on safety stands'

lgnition Timing Inspection and Setting
2.
1.Check the idle speed, and adjust it if necessary (see
section 1 1).
Pull out the service check connector 2P (BRN and
BLK wires) from the connector holder located under
the dash on the front passenger side, then connect
the scs service connector (P/N 07PAz - 0010100) to
it.
Start the engine. Hold the engine at 3,000 rpm with
no load (A/T in N or E, Mff in neutral) until the
radiator fan comes on, then let it idle.
Connect the timing light to the No. I ignition wire,
then point the light toward the pointer on the timing
belt cover.
Check the ignition timing in no load conditions:
headlights, blower fan, rear window defogger, and
air conditioner are not operating.
lgnition Timing:
M/T: 16" 12" BTDC (RED) idling in neutral

6. lf necessary, adjust the ignition timing as follows.
Loosen the distributor mounting bolts, and turn the
distributor ignition (Dl) housing counterclockwise to
advance the timing or clockwise to retard the tim-
t no,

Distributor Replacement
Removal:
1. Disconnect the connector from the distributor.
2. Disconnect the ignition wires from the distributor
ignition (Dl) cap.
3. Remove the mounting bolts from the distributor,
then remove the distributor from the cylinder head.

MOUNTING BOLTS8 x 1.25 mm2,1N.m {2.,1kgrf.m, 17 lbf ftl
lnstallation:
1. Bring the No. 1 piston to compression stroke TDC.
2. Coata new O-ring with engine oil, then install it.
3. Align the lug on the end of the distributor and its
mating grooves in the camshaft end, then slip the
distributor into position.
NOTE: The lug on the end of the distributor and its
mating grooves in the camshaft end are both offset
to eliminate the possibility of installing the distribu-
tor 180o out of time.
4. Installthe mounting bolts, and tighten them lightly.
5. Connect the ignition wires to the distributor ignition(Dl) cap as shown,
No. 1CYLINDERMARK
6. Connect the connector to the distributor.
7. Set the ignition timing (see previous page).
8. After setting the ignition timing, tighten the mount-
ing bolts.

. Perform an input test for the ignition control module(lCM) after finishing the fundamental tests for the
ignition system and the fuel and emissions systems.
. '97 -'98 models: The tachometer should operate nor-
mally if the ICM is OK.

Turn the ignition switch ON {ll). Check for voltage
between the BLK,^/EL wire and body ground. There
should be battery voltage.
. lf there is no battery voltage, check the BLK/rEL
wire betlveen the ignition switch and the lclvl.
. lf there is baftery voltage, go to step 4.
Turn the ignition switch ON (ll). Check for voltage
between the WHT/BLU wire and body ground. There
should be battery voltage.
. lf there is no batteryvoltage, check:- ignition coil.- WHT/BLU wire between the ICM and ignition
corl.
. lf there is battery voltage, go to step 5,
'97 model: Disconnect the ECM/PCM connector A(32P). Check for continuity on the YEL/GRN wire
between the ICM and ECM/PCM. There should be
continuity.'98 - 00 models: Disconnect the ECM,PCM connector
B (25P). Check for continuity on the YEUGRN wire
between the ICM and ECM/PCM. There should be
continuity.
Check for continuity on the YEUGRN wire to body
ground. There should be no continuity.
Reconnect the ECM/PClvl connector.
'97 -'98 models: Check for continuity on the BLU
wire between the test tachometer connector and the
lCM. There should be continuity.
'97 -'98 models: Check for continuity on the BLU
wire to body ground. There should be no continuity.
lf all the tests are normal, replace the lCM.

Valve Seals
Replacement (cylinder head removal not required)
The procedure shown below applies when using the in-
car valve spring compressor (Snap-on YA8845 with
YA8845-2A 7/8" auachment). Use approved eye protec-
tion.
1. Turn the crankshaft so that the No. 1 and the No. 4
pistons are at top dead center (TDC).
2. Remove the cylinder head cover.
3. Remove the distributor.
4. Loosen and disconnect the timing belt from the
camshaft pulleys.
5. Remove the camshaft holder bolts. then remove the
camshaft holders, the camshafts and rocker arms.
lntake Valve Seals
6. 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.
7. Insert the cross shaft through the top hole of the
two uprights,
at.
9.
Select the 7/8 in. diameter long compressor attach-
ment, and fasten the attachment to the front hole of
the lever arm with the speed pin supplied.
Position the piston at TDC, and insen an air adaptor
into the spark plug hole. Pump air into the cylinder
to keep the valve closed while compressing the
springs and removing the valve keepers.
10. Put shop towels over the oil passages to prevent
the valve keepers from falling into the cylinder
head.
Position the lever arm under the cross shaft so the
lever is perpendicular to the shaft and the compres-
sor attachment rests on top of the retainer for the
spring being compressed. Use the rear position slot
on the lever as shown,
