Careful periodic maintenance will help keep your vehicle in the safest, most reliable condition. Inspection, adjustment
and lubrication of important components are explained in the periodic maintenance chart.
Inspect, clean, lubricate, adjust and replace parts as necessary. When inspection reveals the need for replacement
parts, use genuine Polaris parts available from your Polaris dealer.
NOTE: Service and adjustments are critical. If you’re not familiar with safe service and adjustment
procedures, have a qualified dealer perform these operations.
Maintenance intervals in the following chart are based upon average riding conditions and an average vehicle speed of
approximately 10 miles per hour. Vehicles subjected to severe use must be inspected and serviced more frequently.
Severe Use Definition
• Frequent immersion in mud, water or sand
• Racing or race-style high RPM use
• Prolonged low speed, heavy load operation
• Extended idle
• Short trip cold weather operation
Pay special attention to the oil level. A rise in oil level during cold weather can indicate contaminants collecting in the
oil sump or crankcase. Change oil immediately if the oil level begins to rise. Monitor the oil level, and if it continues to
rise, discontinue use and determine the cause or see your dealer.

SEVERE USE ITEM: Severe Use is defined as frequent vehicle immersion in mud, water or sand, racing or race-style
high rpm use, prolonged low speed - heavy load operation or extended idle. More preventative maintenance is
required under these conditions. Fluid changes, cable and chassis lubrication are required more frequently. For engine
oil, short trip cold weather riding also constitutes severe use. Pay special attention to oil level. A rising oil level in cold
weather can indicate contaminants collecting in the oil sump or crankcase. Change oil immediately and monitor level. If
oil level begins to rise, discontinue use and determine cause.
NOTE: Inspection may reveal the need for replacement parts. Always use genuine Polaris parts.
Perform these operations more often for vehicles subjected to severe use.

2. Add POLARIS Carbon Clean Fuel Treatment or
POLARIS Fuel Stabilizer. Follow the instructions on
the container for the recommended amount. Carbon
Clean removes water from fuel systems, stabilizes
fuel and removes carbon deposits from pistons, rings,
valves and exhaust systems.
3. Allow the engine to run for 15-20 minutes to allow the
stabilizer to disperse through the entire fuel delivery
system.
Fog the Engine
1. After stabilizing the fuel, remove the spark plugs and
add 2-3 tablespoons of engine oil. To access the plug
holes, use a section of clear 1/4” hose and a small

2. Reinstall the spark plugs. Torque to specification.
3. Apply dielectric grease to the inside of the spark plug
cap and reinstall the caps onto the plugs.
4. Turn the engine over several times using electric
start. Oil will be forced in and around the piston rings
and ring lands, coating the cylinder with a protective
film of fresh oil.
5. If POLARIS fuel system additive is not used, the fuel
tank, fuel lines, and injectors should be completely
drained of gasoline.
Starting the engine during the storage period will disturb
the protective film created by fogging and damage could
occur. Never start the engine during the storage period.

The engine coolant level is controlled or maintained by
the recovery system. The recovery system components
are the recovery 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 recovery
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.
Some coolant level drop on new machines is normal as
the system is purging itself of trapped air. Observe
coolant levels often during the break-in period.
Overheating of engine could occur if air is not fully
purged from system.
Polaris Premium 60/40 is already premixed and ready to
use. Do not dilute with water.
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.
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
WARNING
Never remove the radiator pressure cap when the
engine is warm or hot. Escaping steam and fluid can
cause severe burns. The engine must be allowed to
cool before removing the pressure cap.
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 via the radiator cap first and
coolant added if necessary.
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 rack storage area.
2. Remove the (4) T-25 screws securing the access
cover to the front cab as shown below.
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.

the top of the filler neck.
6. Reinstall the pressure cap and install the front
access cover.
Cooling System Hoses
1. Inspect all hoses for cracks, deterioration, abrasion
or leaks. Replace if necessary.
2. Check tightness of all hose clamps.

CAUTION
Do not over-tighten hose clamps at radiator,
or radiator fitting may distort,
causing a restriction to coolant flow.
Radiator hose clamp torque is 36 in-lbs (4 Nm).
Cooling System Pressure Test
System Pressure Test
1. Remove radiator cap cover located under the
storage box access panel. See Chapter 3.
2. Remove recovery bottle hose from coolant filler.
3. Connect a Mity-Vac™ (PN 2870975) to radiator and
pressurize system to 10 PSI (68.9 kpa). The system
must retain 10 lbs of pressure for five minutes or
longer. If pressure loss is evident within five minutes,
check radiator, all cooling system hoses and clamps,
or water pump seal.
Radiator Cap Pressure Test
4. Remove radiator cap and test using a cap tester
(commercially available).
5. The radiator cap relief pressure is 13 lbs (89.6 kpa).

Remove the outer clutch cover to access the drive clutch
to aid in engine rotation (manually turn the drive clutch
counter clockwise).
1. With the CPS sensor removed, rotate the engine
until the “V” marked on the flywheel is aligned with
the CPS mounting hole. This will set TDC, but not
necessarily TDC of the compression stroke.
NOTE: View the timing marks on the camshaft
sprockets to ensure the engine is at TDC of the
compression stroke.
2. With the valve cover and thermostat housing
removed, rotate the engine so the cam lobes are
facing outward and the Cylinder Holding and
Camshaft Timing Plate (PU-50563) can be installed
into the slots of the camshafts as shown below. This
will set TDC of the compression stroke.
NOTE: Intake cam sprocket should have “I”
marks aligned with gasket surface and the
exhaust cam sprocket should have “E” marks
aligned with gasket surface.
