COOLING SYSTEM
The AIR VANTAGE ® 700 (AU) CUMMINS is equipped
with a pressure radiator. Keep the radiator cap tight to
prevent loss of coolant. Clean and flush the coolant
system periodically to prevent clogging the passage
and over-heating the engine. When antifreeze is need-
ed, always use the permanent type.
• When draining the entire contents of the system,
remove radiator cap and open vent cock on top of
tank (counter clockwise). Next, pull both drain hoses
through the access hole in the base and open both
valves until system is empty.
• When refilling, close both valves on drain hoses and
open vent cock on top of tank to vent air from system
fully. Close vent cock when done. (See Figure D.1)
