MAINTENANCE
FUEL FILTER / FUEL LINES
This snowmobile is not equipped with an in-line fuel filter. The fuel pump uses a
sock-type pickup filter located within the fuel tank. This filter should only require
maintenance if debris or foreign material enters the fuel tank. An authorized
dealer can provide service.
Contaminated or poor quality fuel may shorten the life of fuel system
components and result in poor engine performance. Always store fuel in clean
fuel containers. If low fuel pressure or reduced engine performance occurs, the
filter may need replacement. An authorized dealer can assist.
Inspect the fuel lines regularly for signs of deterioration or damage. Always
check fuel line condition after periods of storage. Normal deterioration from
weather and fuel compounds may occur. Replace worn or damaged fuel lines
promptly.
Kinking the fuel lines or using a pliers or similar tools to remove fuel lines may
cause damage to the lines. If a fuel line has been damaged or kinked, replace
COOLING SYSTEM
COOLANT
POLARIS recommends the use of POLARIS Antifreeze 50/50 Premix. This
antifreeze is already premixed and ready to use. Do not dilute with water. If the
vehicle will be stored or operated at extremely low temperatures, greater
protection may be required. An authorized dealer can assist.
To ensure that the coolant maintains its ability to protect the engine, we
recommend that the system be completely flushed and drained every five (5)
years and fresh Antifreeze 50/50 Premix.
Any time the cooling system has been drained for maintenance or repair,
replace the coolant with fresh Antifreeze 50/50 Premix.
If coolant flow becomes restricted or plugged, coolant loss, air lock, or engine
damage may result. Most cooling systems are equipped with a filter that should
