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.
NOTICE
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 Periodic Maintenance.

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).
Image
  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.

Radiator and Cooling Fan

Always check and clean the radiator and fan at the intervals outlined in the Periodic Maintenance Chart beginning on Periodic Maintenance.
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.
  1. Check radiator air passages for restrictions or damage.
  2. Carefully straighten any bent radiator fins.
  3. Inspect the cooling fan for smooth rotation.
  4. Remove any obstructions with low pressure compressed air or low pressure water.

Coolant Hoses Inspection

caution
Inspecting the cooling fans while the engine is running or when the engine is still hot can result in injury. Always make sure the engine is both off and sufficiently cooled before inspection.
Inspect coolant hoses for leaks, deterioration or damage at the intervals outlined in the Periodic Maintenance. Leaks may appear as dry traces that are white/grey in color. Replace worn or damaged hoses.
IMPORTANT
Prior to servicing hoses, always make sure the engine has fully cooled and to release latent pressure by removing the surge tank cap.
