Tools and Materials Needed

  • Drain pan
  • Socket wrench set
  • Funnel
  • Clean cloth

Step-by-Step Guide

1. Prepare Your Bike

Ensure your KTM 400RXC is on a stable surface and completely cool before starting. This prevents burns and ensures accurate coolant levels.

2. Drain the Old Coolant

Locate the coolant drain bolt on the bottom of the water pump. 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)

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 appropriate level. Check your owner's manual for the correct coolant type and capacity.

5. Bleed the System

Start the engine and let it idle with the radiator cap off. This allows air bubbles to escape. Once the coolant level stabilizes, top off if necessary and replace the radiator cap.

6. Check for Leaks

Inspect the system for any leaks around the drain bolt and radiator cap. Tighten if necessary.
