Tools and Materials Needed

  • Coolant compatible with KTM 50SX
  • Drain pan
  • Socket wrench set
  • Funnel
  • Clean cloth

Step-by-Step Guide

1. Prepare Your Bike

Ensure the bike is on a stable surface 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)

For a thorough clean, flush the system with distilled water. Reinstall the drain bolt, fill the radiator 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. Final Checks

Turn off the engine and let it cool. Recheck the coolant level and top off if needed. Reinstall the seat and any panels removed earlier.
