MAINTENANCE

Cooling System

Coolant High Temperature Indicator Light

The high temperature indicator light will illuminate when engine cool-

ant temperature becomes too hot for safe continued operation of the 

engine. If you must drive your machine after the high temperature indi-

cator 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, 

drain the system completely every two years and add a fresh mixture of 

antifreeze and distilled water. 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.

MAINTENANCE

Drive Chain Tension

Check drive chain tension weekly and 

before each long trip. To obtain correct 

chain tension: 

1. Rotate the driven clutch counter-

clockwise to move all chain slack to 

the tensioner side. Lock the brake 

lever lock, or have an assistant hold 

the brake lever firmly.

2. Loosen the adjuster bolt jam nut (1).
3. Finger tighten the adjuster bolt (2) 

until it can no longer be adjusted by 

hand, then back off 1/4 turn.

4. Tighten the jam nut while holding 

the adjuster bolt. Torque to 21 ft. 

lbs. (28 Nm).

5. Release the brake lever lock.

Brakes

Hydraulic Brake Inspection

Inspect the brake lever reserve before each use of the snowmobile. See 

page 67.
Brake pads must be replaced when the brake pad material becomes thin-

ner than the backing plate, approximately 1/16" (1.5 mm). A kit is avail-

able for replacing brake pads. See your dealer.

WARNING! Brake failure during operation can result in serious injury or death. 

Properly functioning brakes are vital to your safety. Be sure the brake pads do 

not drag on the disc and that brake lever travel is not excessive. Always replace 

brake pads when the brake pad material becomes thinner than the backing 

plate, approximately 1/16" (1.5mm).

Brake Components

1. Brake Caliper
2. Brake Disc
3. Brake Pad Material 

(Replace when thickness is 

less than 1/16I/1.5 mm).

Excessive Lever Travel

Hydraulic brakes are self-

adjusting, but if excessive 

brake pad clearance develops 

bring the snowmobile to an 

authorized Polaris dealer for 

inspection and adjustment.
