MAINTENANCE AND LUBRICATION

Cooling System

Operation

The overflow bottle (1) is located

in front of the right front tire of the

vehicle. The coolant level must be

maintained between the minimum

and maximum marks on the

overflow bottle.
The engine coolant level is

controlled or maintained by the

recovery system. The recovery

system components are the

overflow bottle, radiator filler

neck, radiator pressure cap and

connecting hose.
As coolant operating temperature increases, the expanding (heated)

excess coolant is forced out of the radiator, past the pressure cap, and

into the overflow bottle. As engine coolant temperature decreases, the

contracting (cooled) coolant is drawn back up from the tank, past the

pressure cap, and into the radiator.
NOTE: Some coolant level drop on new vehicles is normal as the

system is purging itself of trapped air. Observe coolant levels and

maintain as recommended by adding coolant to the overflow bottle.

Adding or Changing Coolant

To ensure that the coolant maintains its ability to protect the engine,

the system be completely drained every two years, and a fresh mixture

of antifreeze and water should be added.
Polaris recommends the use of Polaris Premium 60/40

anti-freeze/coolant or a 50/50 mixture of high quality aluminum

compatible anti-freeze/coolant and distilled water. See page 96 for the

part numbers of Polaris-recommended products.
NOTE: Polaris Premium 60/40 is already premixed and ready to use.

Do not dilute with water.
NOTE: Always follow the manufacturer’s mixing recommendations

for the freeze protection required in your area.
