the specified seal lock adhesive to the bolt, nut or
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 AT 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.

11. Care must be taken when jacking up and supporting the
vehicle. Be sure to lift and support the vehicle at the proper
locations (See page IN±36).
(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.
12. Observe the following precautions to avoid damage to the
following parts:
(a) Do not open the cover or case of the ECU, ECM, PCM
or TCM unless absolutely necessary. (If the IC terminals
are touched, the IC may be destroyed by static
electricity.)
(b) To disconnect vacuum hoses, pull on the end, not the
middle of the hose.
(c) To pull apart electrical connectors, pull on the connector
itself, not the wires.
(d) Be careful not to drop electrical components, such as
sensors or relays. If they are dropped on a hard floor,
they should be replaced and not reused.
(e) When steam cleaning an engine, protect the distributor,
air filter, and VCV from water.
(f) Ne ve r use an imp a ct wre n ch to re mo ve or in sta ll
temperature switches or temperature sensors.
(g) When checking continuity at the wire connector, insert
the tester probe carefully to prevent terminals from
bending.
(h) When using a vacuum gauge, never force the hose onto
a connector that is too large. Use a step±down adapter
instead. Once the hose has been stretched, it may leak.
13. Tag hoses before disconnecting them:
(a) When disconnecting vacuum hoses, use tags to identify
how they should be reconnected.
(b) After completing a job, double check that the vacuum
hoses are properly connected. A label under the hood
shows the proper layout.
