  • Drain pan
  • Socket wrench set
  • Funnel
  • Rags or paper towels
  • Distilled water (optional for flushing)

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)

If desired, flush the system with distilled water to remove any residual coolant or debris. 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 compatible with your 1992 KTM 400RXC.

5. Bleed the System

Start the engine and let it idle for a few minutes. This allows air bubbles to escape from the system. Check the coolant level again and top off if necessary.

6. Check for Leaks

Inspect the area around the drain bolt and radiator for any signs of leaks. Tighten any loose connections if needed.
