Clean up any spilled engine coolant.
After installation, check that all tubes, hoses, and
connectors are installed correctly.
Inspect for fuel leaks. Turn the ignition switch ON
(ll) (do not operate the starter) so that the fuel pump
runs for about 2 seconds and pressurizes the fuel
line. Repeat this operation two or three times, then
check for fuel leakage at any point in the fuel line.
Refill the radiator with engine coolant, and bleed
air from the cooling system with the heater valve
open (see page 10-6).
