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:

Loosen the distributor mounting bolts, and turn the
distributor ignition (Dl) housing counterclockwise to
advance the timing or clockwise to retard the tim-

Alternator Belt Inspection and Adjustment
NOTE: When using a new belt, first adjust the deflectionor tension to the values for the new belt, then readjustthe deflection or tension to the values for the used beltafter running engine for five minutes.
Deflection methodi
Apply a force of 98 N (10 kgt,22lbll, and measure thedeflection between the alternator and crankshaft pulley.
Detlection:
Used Belt:8.5 - 11.5 mm (0.33 - 0.45 inlNew Beft: 5.5 - 8.0 mm 10.22 - 0.31 inl
NOTEr lf the belt is worn or damaged, replace it.

Belt tension gauge m6thod:
Attach the belt tension gauge to the belt and measure thetension. Follow the gauge manufacturer's instructions.
Tension:
Used Belt:340 - /€0 N (35 - 50 kgf, 77 - 1r0 tbf)New Belt: 690 - 880 N (70 - 90 kgf, 150 - 200 tbt)
NOTE: lfthe belt is worn or damaged, replace it.

6. Tighten the locknut, and check the clearance agajn.
Repeat the adjustment if necessary.

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

The "UP" marks should be pointing straight down.
Adjust the valves on No. 4 cylinder.
Rotate the crankshaft 180'counterclockwise to brino
No.2 piston to TDC.

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,

Inspection
Remove the cylinder head cover.
lnspect the timing belt for c.acks and oil or coolant
soaking. Replace the belt if it is oil or coolant
soaked. Remove any oil or solvent that gets on the
belt.
lnspect thisarea for wear.
After inspecting, retorque the crankshaft pulley bolt
to 177 N.m (18.0 kgnm, 130 lbf.ft).
Install the cylinder head cover (see page 6-32).
3.
Tension Adjustment
NOTE:
. Always adjust the timing belt tension with the engine
coto.
. Always rotate the crankshaft counterclockwise when
viewed from the pulley side. Rotating it clockwise
may result in improper adiustment of the belt ten-
sion.
'1. Remove the cylinder head cover
2. Set the No. 1 piston at TDC (see page.6-12).
3. Rotate the crankshaft five or six revolutions to set
the belt.
Set the No. 1 piston at TDC.
Loosen the adjusting bolt 1/2 turn (180') only.
