•
Clean battery posts and cable terminals and assemble.
•
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.
•
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.
