fuel supply to the generator fuel tank The fuel level float

The Engine Cooling System (FIGURE 1-5)
consists of a radiator, hoses, thermostat, water pump, a
belt driven fan, and cooling jackets. 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 air
through the radiator where the coolant temperature is
reduced.

A coolant high temperature switch provides
automatic shut dovvn 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).
