2. Place a drain pan under the drain hole.
3. Remove the drain plug. Allow the oil to drain completely.
4. Clean and reinstall the drain plug with a new sealing washer. Torque 

to specification.

5. Remove the fill plug. Add the recommended oil. Do not overfill.
6. Reinstall the fill plug. Torque to specification.

MAINTENANCE

Cooling System

The engine coolant level is controlled, or maintained, by the recovery 

system. The recovery system components are the recovery bottle, the 

radiator filler neck, the radiator pressure cap and the connecting hose.
As coolant operating temperature increases, the expanding (heated) 

excess coolant is forced out of the engine, past the pressure cap, and into 

the recovery bottle. As engine coolant temperature decreases the 

contracting (cooled) coolant is drawn back up from the bottle, past the 

pressure cap, and into the radiator.
Some coolant level drop on new vehicles is normal as the system is 

purging itself of trapped air. Check the coolant level and maintain as 

recommended by adding coolant to the recovery bottle.
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 139 for the part numbers of POLARIS products.

Recovery Bottle Coolant

Some coolant level drop on new machines is normal, as the system is 

purging itself of trapped air. Add coolant as needed.
Check the coolant level in the radiator any time the recovery bottle has 

run dry. Add coolant as needed.
1. Check the coolant level 

when the fluid is cool.

2. Remove the left side 

panel. See page 109.

3. View the coolant level. 

Maintain the coolant 

level between the 

minimum and maximum 

marks on the bottle 

(when the fluid is cool).

4. Add coolant as needed.
5. Reinstall the side panel.

MAINTENANCE

Cooling System

Radiator Coolant

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.
Any time the cooling system has been drained for maintenance or repair, 

replace the coolant with fresh Antifreeze 50/50 Premix.
If the recovery bottle has run dry, check the level in the radiator. Add 

coolant as needed.

Escaping steam can cause severe burns. Never remove the pressure cap while 

the engine is warm or hot.

1. Open the front box cover.
2. Remove the access panel 

screws. Squeeze the outer 

edges of the panel inward to 

remove the panel.

3. Remove the pressure cap.
4. Using a funnel, slowly add 

coolant through the radiator 

filler neck.

5. Reinstall the pressure cap.

NOTE: Use of a non-standard pressure cap will not allow the recovery system 

to function properly. Use the correct replacement part. Your POLARIS 

dealer can assist.

6. Reinstall the access panel and secure the front box cover.

MAINTENANCE

Brake Fluid

Check brake fluid levels for both brake systems before each ride. 

Always maintain brake fluid at the recommended level. Do not overfill.
The brakes should feel firm when they’re applied. Spongy or weak 

brakes may indicate a fluid leak or low fluid level. A low fluid level 

may also mean that brake pads are worn and need to be replaced. Do not 

operate the vehicle with spongy or weak brakes. Your POLARIS dealer 

can assist.

Operating the Tractor with a spongy brake can result in loss of braking, which 

could cause an accident. Never operate the Tractor with spongy-feeling brakes.

If the fluid level is low add DOT 4 brake fluid only. See page 139 for the 

part numbers of POLARIS products.

An over-full master cylinder may cause brake drag or brake lock-up, which could 

result in serious injury or death. Maintain brake fluid at the recommended level. 

Do not overfill.

Under normal operation, the diaphragm extends into the reservoir as 

fluid level drops. If the fluid level is low and the diaphragm is not 

extended, a leak is likely and the diaphragm should be replaced. To 

ensure proper diaphragm operation, always fill the reservoir as needed 

whenever the cover is loosened or removed. Do not overfill.

Never store or use a partial bottle of brake fluid. Brake fluid is hygroscopic, 

meaning it rapidly absorbs moisture from the air. The moisture causes the 

boiling temperature of the brake fluid to drop, which can lead to early brake fade 

and the possibility of accident or severe injury. After opening a bottle of brake 

fluid, always discard any unused portion.
