6. Precoated Parts
Precoated parts are the bolts, nuts, etc. which are coated
with a seal lock adhesive at the factory.
(a) If a precoated part is tightened, loosened or caused
to move in any way, it must be recoated with the
specified adhesive.
(b) Recoating of Precoated Parts
(c)
( 1 ) Clean off the old adhesive from the part's
threads.
(2) Dry with compressed air.
(3) Apply the specified seal lock adhesive to the
part's threads.
Precoated parts are indicated in the component
mustrations by the symbol
"* ".
7. When necessary, use a sealer on gaskets to prevent leaks.
8. Carefully observe all specifications for bolt torques.
Always use a torque wrench.
9. Use of special service tools (SST) and special service
materials (SSM) may be required, depending on the nature
of the repair. Be sure to use SST and SSM where specified
and follow the proper work procedure. A list of SST and
SSM can be found at the back of this manual.
10. When replacing fuses, be sure the new fuse is the correct
amperage. DO NOT exceed the fuse amp rating or use one
of a lower rating.
11. Care must be taken when jacking up and supporting the
vehicle. Be sure to lift and support the vehicle at the
proper locations.
(a) If the vehicle is to be jacked up only at the front or
rear end, be sure to chock the wheels 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
the vehicle raised on a jack alone. even for a small job
that can be finished quickly.
12. Observe the following precautions to avoid damaging the
parts:
(a) Do not open the cover or the case of the ECU 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 of the
hose, not the middle.
(c)
To pull apart electrical connectors, pull on the con-
nector itself, not the wires.
