Tools and Materials Needed

  • Drain pan
  • Socket wrench set
  • Funnel
  • Rags or paper towels
  • Safety gloves

Step-by-Step Guide

1. Prepare the Bike

Ensure the bike is on a stable stand and the engine is cool to the touch. This prevents burns and ensures the coolant drains completely.

2. Drain the Old Coolant

Locate the coolant drain bolt on the water pump cover. Place a drain pan underneath and use a socket wrench to remove the bolt. Allow the old coolant to fully drain into the pan.

3. Flush the System (Optional)

If the coolant appears dirty or contaminated, consider flushing the system with distilled water. Reinstall the drain bolt, fill the system with distilled water, run the engine briefly, then drain again.

4. Refill with New Coolant

Reinstall the drain bolt securely. Using a funnel, pour the new coolant into the radiator until it reaches the appropriate level. Be sure to use a coolant that is compatible with the KTM 65SX.

5. Bleed the System

Start the engine and let it idle for a few minutes. This helps remove any air pockets in the system. Check the coolant level again and top off if necessary.

6. Clean Up

Wipe any spilled coolant from the bike and dispose of the old coolant responsibly. Check for leaks around the drain bolt and radiator cap.
