MOTOR AID WATER HEATER
The motor aid uses heat from the chassis en-
gine cooling system to heat water in the water
heater while driving. Hoses are routed from the
engine to a heat exchanger surrounding the water
heater tank.
Under normal conditions, the entire contents
of the water heater can be heated to about 120°F
in about two hours or 100 miles of driving. This
means you can have hot water at the faucets im-
mediately upon arriving at a site, or even while
driving if needed.
The motor aid also increases the capacity of
the engine cooling system, allowing the engine to
run cooler under many conditions.

CAUTION
Any leak in the heat exchanger or its

and the heater to insure that no leaks
have developed.
