Step-by-Step Guide

1. Prepare Your Bike

Ensure your bike 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 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)

For a thorough clean, flush 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 50SX.

5. Bleed the System

Start the engine and let it idle. This helps remove air pockets from the system. Check the coolant level again and top off if necessary.

6. Clean Up

Wipe any spilled coolant with a clean cloth and dispose of the old coolant responsibly. Check for leaks around the drain bolt and radiator cap.
