vacuum hose (B) and breather pipe (C).
12. Install the engine cover.
13. Inspect for fuel leaks. Turn the ignition switch to ON (II) (do not operate the starter) so the fuel pump
runs for about 2 seconds and pressurizes the fuel
line. Repeat this operation three times, then check
for fuel leakage at any point in the fuel line.
14. Clean up any spilled engine coolant.
15. After installation, check that all tubes, hoses and connectors are installed correctly.
16. Refill the radiator with engine coolant, and bleed the air from the cooling system with the heater
valve open (see step 6 on page 10-8).
