MAINTENANCE
Cooling System Pressure Test
Refer to Chapter 3 for pressure test procedure.
Coolant Level Inspection
The recovery bottle, located on the left side of the machine, must
be maintained between the minimum and maximum levels
indicated on the recovery bottle.
With the engine at operating temperature, the coolant level
should be between the upper and lower marks on the coolant
reservoir. If not:
1. Remove reservoir cap. Inner splash cap vent hole must be
clear and open.
2. Fill reservoir to upper mark with Polaris Premium 60/40
Anti Freeze / Coolant or 50/50 or 60/40 mixture of
antifreeze and distilled water as required for freeze
protection in your area.
3. Reinstall cap.
NOTE: If overheating is evident, allow system to cool
completely and check coolant level in the radiator and
inspect for signs of trapped air in system.
Radiator Coolant Level Inspection
NOTE: This procedure is only required if the cooling
system has been drained for maintenance and/or repair.
However, if the recovery bottle has run dry, or if
overheating is evident, the level in the radiator should be
inspected and coolant added if necessary.
NOTE: Use of a non-standard pressure cap will not
allow the recovery system to function properly.
To access the radiator pressure cap:
1. Open the front cargo storage.
2. Remove the inside cover over the radiator cap.
Air Filter/Pre-Filter Service
It is recommended that the air filter and pre filter be replaced
annually. When riding in extremely dusty conditions,
replacement is required more often.
The pre filter should be cleaned before each ride using the
following procedure:
1. Lift up on the rear of the seat.
2. Pull the seat back and free of the tabs. NOTE: When
reinstalling seat, make sure the slots in the seat engage the
tabs in the fuel tank.
3. Remove clips (A) from air box cover and remove cover.
Inspect the gasket. It should adhere tightly to the cover and
seal all the way around.
WARNING
Never remove the pressure cap when the engine is
warm or hot. Escaping steam can cause severe burns.
The engine must be cool before removing the
pressure cap.
