MAINTENANCE

Fuses

If the engine stops or will not start, or if you experience other electrical 

failures, a fuse may need replacement. Locate and correct any short 

circuits that may have caused the blown fuse, then replace the fuse.

The fuse box is located under the seat. Spare fuses are provided in the 

fuse box.

MAINTENANCE

Cooling System

Operation

The engine coolant level is controlled or maintained by the recovery 

system. The recovery system components are the overflow 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 overflow 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.

Tip: Some coolant level drop on new vehicles is normal as the system is purging 

itself of trapped air. Observe coolant levels and maintain as recommended 

by adding coolant to the overflow bottle.

Adding or Changing 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 134 for the part numbers of POLARIS products.
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.

MAINTENANCE

Cooling System

Radiator and Cooling Fan

Always check and clean the screen and radiator fins at the intervals 

outlined in the Periodic Maintenance Chart beginning on page 85. Do 

not obstruct or deflect air flow through the radiator by installing 

unauthorized accessories in front of the radiator or behind the cooling 

fan. Interference with the radiator air flow can lead to overheating and 

consequent engine damage.

NOTICE: Washing the vehicle with a high-pressure hose could damage the 

radiator fins and impair the radiator's effectiveness. Using a high-

pressure system is not recommended.

Radiator Coolant Level

This procedure is required only if the cooling system has been drained 

for maintenance and/or repair. But if the overflow bottle has run dry, the 

level in the radiator should also be inspected.

CAUTION! Escaping steam can cause burns. Never remove the pressure cap 

while the engine is warm or hot. Always allow the engine to cool before 

removing the pressure cap.

1. Remove the front box 

cover and access panel. 

See page 27.

2. Slowly remove the 

radiator cap.

3. View the coolant level 

through the opening.

4. Use a funnel and slowly 

add coolant as needed.

Tip: Use of a non-standard 

pressure cap will not allow 

the recovery system to 

function properly. See your 

POLARIS dealer for the correct replacement part.
