switch shuts off the auxiliary fuel pump when the genera-
tor fuel tank is full and reactivates the pump as the level
drops. The FUEL LEVEL indicator indicates fuel level of
generator fuel tank from (E) empty to (F) full in quarter
tank increments.
1-13 ENGINE COOLING SYSTEM..
1-13.1 The Engine Cooling System (Figure 1-5) consists
of a radiator, hoses, thermostat, water pump, a belt driven
fan, cooling jackets and oil cooler. The water pump forces
coolant through passages (cooling jackets) in the engine
block and cylinder head where the coolant absorbs heat
from the engine. When the engine reaches normal operat-
ing temperature, the thermostat opens and the heated cool-
ant flows through the upper radiator hose assembly into
the radiator. The cooling fan circulates air through the
radiator where the coolant temperature is reduced.
1-13.2 A coolant high temperature switch provides auto-
matic shut down in the event that coolant temperature
exceeds 225 ± 5°F (107 + 3°C) . The COOLANT TEMP
indicator indicates the engine coolant temperature, from
120°F to 240°F (48°C to 115°C).
