MOTOR AID
–Optional
The motor aid uses heat from the chassis
engine 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 140
°
F
in about two hours or 100 miles of driving. This
means you can have hot water at the faucets
immediately 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.
Motor Aid Water Heater and Rear
Auxiliary Heater Maintenance
Have your authorized dealer check all hose
clamp connections on the rear automotive heater
and the motor aid water heater at least every six
months and tighten them if necessary.
CAUTION
Any leak in the heat exchanger or its
supply or return lines could cause loss of
coolant and subsequent engine failure.
We recommend that you periodically
inspect these connecting lines and the
heater to insure that no leaks have
developed.
