fuel tank. The fuel level float switch shuts off the
auxiliary fuel pump when the generator 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.

The Engine Cooling System (FIGURE
1-13.1
1-5) consists of a radiator, hoses, thermostat, water
pump, a belt driven fan, and cooling jackets (part of
engine). 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
operating temperature, the thermostat opens and the
heated coolant flows through the upper radiator hose
assembly into the radiator. The cooling fan circulates
a i r through the radiator where the coolant
temperature is reduced.
A coolant high temperature switch
1-13.2
provides automatic shut down in the event that
coolant temperature exceeds 220 + 3.5 F (104 +
2C). The COOLANT TEMP indicator indicates the
engine coolant temperature, from 120 F to 240 F
(48C to 115C).
