MAINTENANCE

Oil Lines

Inspect oil line condition every 1000 miles (1600 km).

Oil Filter

The oil filter is located at the side of 
the oil tank. Have your dealer change 
the oil filter and bleed the system 
annually or every 1000 miles (1600 
km). 

Tip: The direction of the arrows indicates 

the direction of flow through the fil-
ter.

Exhaust System

Check the exhaust system for wear or damage at the intervals outlined in 
the Periodic Maintenance Table beginning on page 85.

CAUTION! Hot exhaust system parts can cause burns. Allow adequate time for 
the exhaust system to cool. Never perform this procedure with the engine 
running.

1. Allow the engine and exhaust system to cool completely.

2. Open the hood.

3. Inspect the muffler and pipes for cracks or damage. Check for weak 

or missing retaining springs or damper/support grommets.

4. Replace any damaged or missing components.

5. Close the hood.

MAINTENANCE

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. See page 122 for the part numbers of POLARIS products.

Any time the cooling system has been drained for maintenance or repair, 
replace the coolant with fresh Antifreeze 50/50 Premix.

Tip: Never add tap water to the cooling system. Minerals cause deposits and 

may react adversely with the metals in the engine and cooling system.

Coolant Level

The engine coolant level is controlled by the recovery system. The 
recovery system components are:

• Coolant reservoir bottle

• Filler neck

• Pressure cap

• Connecting hoses

Always maintain the coolant level at the “COLD FILL” mark on the 
coolant overflow tank (when the engine is cold).

NOTICE: Operating the snowmobile with insufficient coolant will result in 

overheating and serious engine damage. Always maintain the coolant 
level as recommended.

MAINTENANCE

Cooling System

Coolant High Temperature Indicator Light

The high temperature indicator light will illuminate when engine 
coolant temperature becomes too hot for safe continued operation of the 
engine. If you must drive your machine after the high temperature 
indicator light has come on, drive slowly and stop frequently to allow 
the engine to cool down. Driving in deep snow will also help cool the 
engine. See your dealer for service. 

Add coolant if the level is low. Engine performance will be reduced if 
you continue operating when the high temperature light is on.

Flushing the Cooling System

To ensure that the coolant maintains its ability to protect the engine, we 
recommend that the system be completely drained every five (5) years 
and fresh Antifreeze 50/50 Premix added. This service must be 
performed when the engine is cold. Ask your POLARIS dealer to check 
the coolant when he performs the fall tune-up on your snowmobile.

MAINTENANCE

Cooling System

Bleeding the Cooling System

CAUTION! Steam and hot liquids will cause burns to your skin. Never bleed the 
cooling system or remove the pressure cap when the engine is warm or hot.

Use of a non-standard pressure cap will not allow the recovery system to 
function properly. If the pressure cap needs replacement, contact your 
dealer for the correct part.

NOTICE: 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 be periodically inspected or replaced.

Perform the bleeding procedure when the engine is cold.

1. Position the vehicle so that the top of the tunnel is level. Elevate the 

front of the vehicle slightly if necessary.

2. Remove the pressure cap and fill the coolant bottle with properly 

mixed coolant to the maximum mark.

3. Remove the bleed screw from the water outlet manifold and/or the 

thermostat housing. Allow the coolant to bleed through the system 
until it runs out the bleed holes. Reinstall the bleed screw into the 
manifold.

4. Add coolant to the coolant bottle to the maximum mark.

5. Start the engine and run at a fast idle for two to three minutes. 

Loosen the bleed screw occasionally to purge any trapped air.

6. Stop the engine and check the coolant bottle level. Fill as required.

7. Feel the heat exchangers under the running boards. If the system is 

bled properly, they'll be warm to the touch. If they're not, repeat step 
5. Lift the front of the machine slightly to assist in the bleeding.

8. Replace the pressure cap and carefully lower the front end of the 

machine.
