COOLING SYSTEM

The AIR VANTAGE ® 800 (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 needed, 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)
