These units are used with any size radiator and use water from the pump to
help maintain the proper temperature of the engine coolant during pumping.
2A.4 ENGINE GOVERNOR CONTROL, OPTIONAL
The optional engine governor minimizes changes
of pressure when volumes of water are changed.
It is accomplished by changing engine speed to
compensate from changes in pressure. (See Fig-
ure 2a-4: “Optional - Engine Governor Control.”)
Also see manufacturer’s separate manual pro-
vided for additional information.

Note: The engine governor replaces the standard
relief valve pressure control.
