MAINTENANCE AND LUBRICATION
Engine Cooling System
NOTE: To ensure that the coolant maintains its ability to protect the
engine, we recommend that the system be completely drained every
two years and a fresh mixture of antifreeze and water 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. Polaris Premium 60/40 is already premixed and
ready to use. Do not dilute with water. See page 141 for the part
numbers of Polaris-recommended products.
NOTE: Always follow the manufacturer’s mixing recommendations
for the freeze protection required in your area.
Oil Pump Bleeding - 2-Cycle Engines
1. Fill the oil reservoir with Polaris Premium 2-Cycle Oil. NOTE:
See page 141 for the part numbers of Polaris-recommended
products.
2. If the oil supply line has been disconnected from the pump, or if
the oil reservoir and supply line have been completely run out of
oil, loosen the bleeder screw one full turn (skip this step if
conditions do not apply). Allow oil to flow from the bleed screw
for five to ten seconds, then tighten the bleed screw.
3. Start the engine and rotate the oil pump lever to its full open
position. With the engine at idle, hold the lever up for thirty
seconds to purge all air from the system.
CAUTION
Allowing the engine to run while the bleed screw is loose will result
in loss of oil, which will cause serious engine damage. Always
retighten the bleed screw if it’s been loosened for service.
