MAINTENANCE
Cooling System
The engine coolant level is maintained by the recovery system. The recovery system
components are the recovery bottle, recovery bottle pressure cap and connecting hose.
As coolant operating temperature increases, the expanding (heated) excess coolant is forced
out of the radiator and into the recovery bottle. As engine coolant temperature decreases, the
contracting (cooled) coolant is drawn back from the tank and into the radiator.
NOTE: 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 recovery
bottle.
Coolant
Always use POLARIS SLINGSHOT 50/50 Antifreeze or another DEX-COOL®-approved
50/50 premixed antifreeze for your vehicle. DO NOT use POLARIS Antifreeze 50/50
Premix.
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 added. See your
authorized dealer for this service.
Always check and change the coolant at the intervals outlined in the Periodic Maintenance
Chart beginning on page 51.
Coolant Level
Always check the coolant level when the engine is cold. Maintain the coolant level at the
“cold” fill level mark on the recovery bottle (when the fluid is cool).
1. Position the vehicle on a
level surface.
2. Open the hood.
3. View the coolant level in the
recovery bottle.
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.
4. If the level is low, slowly
remove the pressure cap.
Use a funnel to add coolant
to the fill level mark.
5. Reinstall the pressure cap.
NOTE: If coolant must be added often, or if the recovery bottle runs completely dry, there may be a
leak in the system. Have the cooling system inspected by your dealer.
