Step-by-Step Guide

1. Prepare the Bike

Ensure the bike is on a stable surface and the engine is cool. This prevents burns and ensures safety while working on the bike.

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 completely drain out. Dispose of the old coolant responsibly as it is toxic.

3. Flush the System (Optional)

If the coolant appears dirty or contaminated, consider flushing 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 to prevent any damage to the engine.

5. Bleed the System

Start the engine and let it run for a few minutes. This helps to remove any air pockets in the system. Check the coolant level again and top off if necessary.

6. Final Check

Inspect for any leaks around the drain bolt and radiator cap. Ensure everything is tightened properly. Clean any spilled coolant with rags or paper towels.
