Step-by-Step Guide

1. Prepare Your Bike

Ensure the bike is on a stable surface and completely cool before starting. This prevents burns and ensures accurate coolant levels.

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 out.

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.

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 65SX.

5. Bleed the System

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