| D. |
Refill a radiator and
a reservoir tank with engine coolant. |
| E. |
Clean battery posts and
cable terminals and assemble. |
| F. |
Inspect for fuel leakage.
|
| - |
After assemble the fuel
line, turn on the ignition switch (do not operate the starter) so
that the fuel pump runs for approximately two seconds and fuel line
pressurizes. |
| - |
Repeat this operation
two or three times, then check for fuel leakage at any point in
the fuel line. |
| G. |
Bleed air from the cooling
system. |
| - |
Start engine and let
it run until it warms up. (until the radiator fan operates 3 or
4 times.) |
| - |
Turn Off the engine.
Check the level in the radiator, add coolant if needed. This will
allow trapped air to be removed from the cooling system. |
| - |
Put radiator cap on tightly,
then run the engine again and check for leaks. |
