Cooling System

The engine coolant level is controlled by the recovery system. 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.
INDIAN recommends the use of Antifreeze 50/50 Premix. This antifreeze is already premixed and ready to use. Do not dilute with water.
To ensure that the coolant maintains its ability to protect the engine, we recommend that the system be completely drained every five (5) years or 50,000 miles (80,467 km), whichever comes first. Please see your dealer for this service.

Coolant Level Inspection

NOTICE
A flashlight is required for viewing the coolant level.
  1. Allow the engine to cool before checking coolant level.
  2. Position the motorcycle on level ground in the fully upright position.
  3. Place a flashlight flush against an accessible area of the recovery bottle to illuminate the interior. View the coolant level through the window in the heat shield.

  4. Maintain the coolant level at the COLD FULL mark on the recovery bottle (when the fluid is cool).
  5. If the level is low, remove the seat to access the coolant fill cap .Image
    NOTICE
    The recovery bottle is vented to prevent overfilling. Coolant will vent onto the ground if overfilled.
  6. Remove the fill cap and add coolant. Do not overfill.
  7. Reinstall the cap.
