Tools and Materials Needed

  • Coolant suitable for KTM 65SX
  • Drain pan
  • Socket wrench set
  • Funnel
  • Rags or paper towels

Step-by-Step Guide

1. Prepare Your Bike

Ensure the bike is on a stable stand and the engine is cool to prevent burns. Remove the seat and any panels obstructing access to the radiator cap.

2. Drain the Old Coolant

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

3. Flush the System (Optional)

If the coolant is particularly dirty, 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 top. Check for any leaks around the drain bolt.

5. Bleed the System

Start the engine and let it idle. As the engine warms, air bubbles may rise to the top. Add more coolant if necessary to maintain the correct level.

6. Reassemble the Bike

Once the coolant level is stable, replace the radiator cap, seat, and any panels you removed. Ensure everything is securely fastened.
