COOLING SYSTEM
The DUAL VANTAGE 700-I is equipped with a pres-
®
sure 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.
• Every 500 hours check radiator to ensure there is no
fin blockage or leaks. Clean as necessary with an
environmentally friendly degreaser and low pressure
water.
• Check coolant recovery bottle every 100 hours for
sufficient coolant. With engine hot and off, level
should be at maximum.
• 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)
