Cooling System

The engine coolant level is controlled, or maintained, by the recovery
system. The recovery system components are the recovery bottle, the
radiator filler neck, the radiator pressure cap and the connecting hose.
As coolant operating temperature increases, the expanding (heated)
excess coolant is forced out of the engine, past the pressure cap, and into
the recovery bottle. As engine coolant temperature decreases the
contracting (cooled) coolant is drawn back up from the bottle, past the
pressure cap, and into the radiator.
Some coolant level drop on new vehicles is normal as the system is
purging itself of trapped air. Check the coolant level and maintain as
recommended by adding coolant to the recovery bottle.
POLARIS recommends the use of POLARIS Antifreeze 50/50 Premix.
This antifreeze is already premixed and ready to use. Do not dilute with
water. See page 145 for the part numbers of POLARIS products.
