FUNDAMENTAL PROCEDURES G
Depending on where they are;
1. Sealant should be applied to gaskets
2. Oil should be applied to the moving components
of parts
3. Specified oil or grease should be applied at the
prescribed locations (oil seals, etc.) before as-
sembly.
47U0GX-012
ADJUSTMENTS
Use suitable gauges and/or testers when making var-
ious adjustments.
67U0GX-002
ELECTRICAL SYSTEM
Be sure to disconnect the battery cable from the nega-
tive (-) terminal of the battery.
Never pull on the wiring when disconnecting con-
nectors.
When locking connectors, make sure to listen for a
click that will let you know they are securely locked.
Handle sensors and relays carefully. Be careful not
to drop them or strike them against other parts.

76G01A-102
76G01A-103
76G01A-104
TUNE-UP PROCEDURE
Tune the engine according to the procedures
described below.
Battery
1. Check for corrosion on the terminals, or loose ca-
ble connections.
If necessary, clean the clamps and tighten firmly.
2. Check that the electrolyte level is between the UP-
PER and LOWER marks.
Add distilled water if necessary.
3. Check the specific gravity by using a hydrometer.
If the specific gravity reading is 1.200 or less,
recharge the battery. (Refer to Section 5.)
Air Cleaner Element
Visually check the air cleaner element for excessive
dirt, damage, or oil. Replace if necessary.
Caution
Do not clean the air cleaner element with com-
pressed air, replace if necessary.
Engine Oil
Check the engine oil level and condition with the oil
level gauge.
Add oil, or change it, if necessary.

ON-VEHICLE INSPECTION 1 A
ON-VEHICLE INSPECTION
If the engine exhibits low power, poor fuel economy,
or poor idle, check the following points.
1. Ignition system (Refer to Section 5)
2. Compression
3. Fuel system (Refer to Section 4)
COMPRESSION
1. Check that the battery is fully charged. Recharge
if necessary.
76G01A-107
2. Warm up the engine to the normal operating tem-
perature.
3. Turn it off for about 10 minutes to allow the exhaust
manifold to cool.
4. Remove all spark plugs.
5. Disconnect the primary wire connector from the
ignition coil.

7. Fully depress the accelerator pedal and crank the
engine.
8. Note the maximum gauge reading.
9. Check each cylinder.
