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 engine. 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 the coolant is particularly dirty, consider flushing the system with distilled water. Reinstall the drain bolt, fill the system with water, run the engine briefly, then drain again.

4. Refill with New Coolant

Once drained, reinstall the drain bolt securely. Use a funnel to pour 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 run for a few minutes. This helps remove any air pockets. 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.
