CONTROL AND PARTS FUNCTIONS
Engine Cooling System
To insure that the coolant maintains its ability to protect the engine, it is recom-
mended that the system be completely drained every two years and a fresh mixture
of antifreeze and water be added. Polaris recommends the use of Polaris Pre-
mium 60/40 anti-freeze/coolant or a 50/50 mixture of high quality aluminum com-
patible anti-freeze/coolant and distilled water. NOTE: Polaris Premium 60/40 is
already premixed and ready to use. Do not dilute with water. IMPORTANT: Al-
ways follow the manufacturer's mixing recommendations for the freeze protection
required in your area.
Using a funnel, slowly add coolant as necessary.
