ENGINE OIL INSPECTION
1. CHECK OIL QUALITY
Check the oil for deterioration, entry of water, dis±
coloring or thinning.
If oil quality is visibly poor, replace it.
Oil grade:
API grade SG or SH, Energy Conserving II multi±
grade engine oil or ILSAC multigrade engine oil.
Recommended viscosity is as shown in the illustra±
tion.
TUNE±UP
ENGINE COOLANT INSPECTION
1. CHECK ENGINE COOLANT LEVEL AT RESERVOIR
TANK
The engine coolant level should be between the
ªLOWº and ªFULLº lines at low temperature.
If low, check for leaks and add engine coolant up to
the ªFULLº
2. CHECK ENGINE COOLANT QUALITY
There should be no excessive deposits of rust or
scales around the radiator cap or radiator filler hole,
and the engine coolant should be free from oil.
If excessively dirty, replace the engine coolant.
2. CHECK ENGINE OIL LEVEL
The oil level should be between the ªLº and ªFº marks
on the dipstick.
If low, check for leakage and add oil up to the ªFº
mark.

HINT:
wBefore measuring the voltage, turn the ignition
switch to LOCK and turn off the electrical sys±
tems (headlight, blower motor, rear defogger etc.)
for 60 seconds to remove the surface charge.
wIf the vehicle has been running, wait 5 minutes or
more after the vehicle stops before measuring
the battery voltage.
If the voltage is less than specification, charge the
battery.
HINT: Check the indicator as shown in the illustration. 1. Except Delco Battery:
CHECK BATTERY ELECTROLYTE LEVEL

GENERATOR DRIVE BELT INSPECTION
INSPECT DRIVE BELT
(a) Visually check the drive belt for excessive wear,
frayed cords etc.
If any defect has been found, replace the drive belt.
HINT: Cracks on the rib side of a drive belt are consid±
ered acceptable. If the drive belt has chunks missing
from the ribs, it should be replaced.4. INSPECT HIGH±TENSION CORD RESISTANCE
Using an ohmmeter, measure the resistance.
Maximum resistance:
25 k per cord
If the resistance is greater than maximum, check the
terminals. If necessary, replace the high ± tension
cord.

New belt
175 + 5 lbf
Used belt
130 + 10 lbf
w/o A/C
New belt
125 + 25 lbf
Used belt
95 + 20 lbf
If the belt tension is not as specified, adjust it.
HINT:
wªNew beltº refers to a belt which has been used
less than 5 minutes on a running engine.
wªUsed beltº refers to a belt which has been used
on a running engine for 5 minutes or more.
wAfter installing a belt, check that it fits properly in
the ribbed grooves.
wCheck with your hand to confirm that the belt has
not slipped out of the groove on the bottom of
the pulley.
wAfter installing a new belt, run the engine for
about 5 minutes and recheck the belt tension.
VALVE CLEARANCE INSPECTION AND
ADJUSTMENT
HINT: Inspect and adjust the valve clearance when
the engine is cold.
1. DISCONNECT HIGH ± TENSION CORDS FROM
SPARK PLUGS
Disconnect the high ± tension cords at the rubber
boot. DO NOT pull on the cords.
NOTICE: Pulling on or bending the cords may damage the
conductor inside.
2. REMOVE CYLINDER HEAD COVER
(a) Disconnect the PCV hoses.
(b) Loosen the 2 wire harness clamp bolts (No.2 timing
belt cover) mounting bolts.
(c) Remove the 4 nuts, grommets, head cover and gasket.

4. INSPECT VALVE CLEARANCE
(a) Check only the valves indicated.
Using a thickness gauge, measure the clearance
between the valve lifter and camshaft.
Record the out± of ±specification valve clear±
ance measurements. They will be used later to
determine the required replacement adjusting
shim.
Valve clearance (Cold):
Intake
0.19 ± 0.29 mm (0.007 ± 0.011 in.)
Exhaust
0.28 ± 0.38 mm (0.011 ± 0.015 in.) 3. SET NO.1 CYLINDER TO TDC/COMPRESSION
(a) Turn the crankshaft pulley and align its groove with
timing mark ª0º of the No.1 timing belt cover.
(b) Check that the valve lifters on the No.1 cylinder are
loose and valve lifters on the No.4 are tight.
If not, turn the crankshaft one revolution (360*) and
align the mark as above.
(b) Turn the crankshaft one revolution (360) and align
the mark as above. (See procedure in step 3)
(c) Check only the valves indicated as shown. Measure
the valve clearance. (See procedure in step (a)) HINT: Arrange the grommets in correct order, so that
they can be reinstalled into their original positions.
This minimizes any possibility of oil leakage due to
reuse of grommets.
± 5S±FE ENGINEENGINE MECHANICALEG1±13
Page 64 of 4770

(b) Determine the replacement adjusting shim size by
following the Formula or Charts:
wUsing a micrometer, measure the thickness of
the removed shim.
wCalculate the thickness of a new shim so that the
valve clearance comes within specified value.
T ........... Thickness of removed shim
A ........... Measured valve clearance
N ........... Thickness of new shim
Intake:
N = T + (A ± 0.24 mm (0.009 in.))
Exhaust:
N = T + (A ± 0.33 mm (0.013 In.))
wSelect a new shim with a thickness as close as
possible to the calculated value.
HINT: Shims are available in seventeen sizes in incre±
ments of 0.05 mm (0.0020 in.), from 2.50 mm (0.0984
in.) to 3.30 mm (0.1299 in.).5. ADJUST VALVE CLEARANCE
(a) Remove the adjusting shim.
wTurn the crankshaft so that the cam lobe for the
valve to be adjusted faces up.
wUsing SST (A), press down the valve lifter and
place SST (B) between the camshaft and valve
lifter. Remove SST (A).
SST 09248 ± 55020 (09248 ± 05011, 09248±05021)
HINT: Before pressing down the valve lifter, position
its notch toward the spark plug side.
w Remove the adjusting shim with a' small screw±
driver and magnetic finger.
HINT: For easy removed of the shim, when positioning
SST (B), set it on the lifter so there is space enough to
be able to remove the shim.
