7. When necessary, apply sealant to gaskets to prevent
leakage.
8. Strictly observe all specifications for bolt tightening
torques (see Table 2-6-1, 2-6-2), and use the torque
spanner according to technical requirements, as shown
in Fig. 1-7-3.
9. Special repair tools, instruments (see Table 2-11-1)
and special repair materials (see Table 2-6-8, 2-6-9)
may be used, depending on the repair. Be sure to use
special repair tools and special repair materials as
required according to situations, and strictly observe
correct operation specifications. A list of special repair
tools and special repair materials can be found in
"Chapter II
Technical Information of Engine‖ in this
manual.
10. Be sure to take care when jacking up and
supporting the vehicle. Be sure to lift and support the
vehicle at the proper locations.
10.1 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.
10.2 Be sure to hold the vehicle with a support after it is
jacked up. 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. Observe the following precautions to prevent
damage to parts:
11.1 Non-specialized personnel should not open the
cover or housing of the electric control unit (ECU).
11.2 When disconnecting the fuel return hose
component and the vacuum hose of the fuel injector,
hold the end but not the middle of the hose, as shown in
Fig. 1-7-5.
11.3 To pull apart the circuit connectors, pull the
connector itself but not the wires, as shown in Fig.
1-7-6.
11.4 Be careful not to drop precision parts, EFI system
elements (such as the oil injector, sensor, ECU, etc.) off,
as shown in Fig. 1-7-7.If they are dropped, they should
be replaced with new parts.
11.5 Never use an impact spanner to disassemble or
mount a temperature sensor or other sensors which has
specific torque requirements.
