If your model is equipped with
power steering, frequently clean
the areas around and on the
power steering unit to allow
proper cooling. Clean these areas
thoroughly.

Cooling System

The engine coolant level is controlled by the recovery system. 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 con-
tracting (cooled) coolant is drawn back up from the bottle, past the pres-
sure 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 Premium 60/40 anti-freeze/cool-
ant or a 50/50 mixture of high quality aluminum compatible anti-freeze/
coolant and distilled water. Polaris Premium 60/40 is already premixed
and ready to use. Do not dilute with water. See page 125 for the part
numbers of Polaris products.
Always follow the manufacturer's mixing recommendations for the
freeze protection required in your area.
