element seal or filter can.

COOLING SYSTEM

The Dual Maverick ® 450 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.
• 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.
• When draining the entire contents of the system, remove
radiator cap. Pull drain hose through the battery access door in
the base and open shut off valve until system is empty.
• When refilling, close shut off valve on drain hose.
