threads.
(c) Precoated parts are indicated in the component il-
lustrations by the º
º symbol.
7. When necessary, use a sealer on gaskets to prevent
leaks.
8. Carefully observe all specifications for bolt tightening
torques. Always use a torque wrench.
9. Use of special service tools (SST) and special service ma-
terials (SSM) may be required, depending on the nature
of the repair. Be sure to use SST and SSM where speci-
fied and follow the proper work procedure. A list of SST
and SSM can be found at the preparation of AX section.
10. When replacing fuses, be sure the new fuse has the cor-
rect amperage rating. DO NOT exceed the rating or use
one with a lower rating.
11. To pull apart electrical connectors, pull on the connector
itself, not the wires.
12. Care must be taken when jacking up and supporting the
vehicle. Be sure to lift and support the vehicle at the prop-
er locations.
(a) If the vehicle is to be jacked up only at the front or
rear end, be sure to block the wheels at the opposite
end in order to ensure safety.
(b) After the vehicle is jacked up, be sure to support it on
stands. It is extremely dangerous to do any work on
a vehicle raised on a jack alone, even for a small job
that can be finished quickly.

4. CHECK BATTERY TERMINALS, FUSIBLE LINK AND
FUSES
(a) Check that the battery terminals are not loose or cor-
roded.
If the terminals are corroded, clean the terminals.
(b) Check the fusible link, H±fuses, M±fuse and fuses for
continuity.
5. INSPECT DRIVE BELTS
(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 considered acceptable.
If the drive belt has chunks missing from the ribs, it should be
replaced.
(b) Using a belt tension gauge, measure the belt tension.

HINT:

ºNew beltº refers to a belt which has been used less than
5 minutes on a running engine.

ºUsed beltº refers to a belt which has been used on a run-
ning engine for 5 minutes or more.

After installing a belt, check that it fits properly in the
ribbed grooves.

Check with your hand to confirm that the belt has not
slipped out of the groove on the bottom of the pulley.
