Step-by-Step Guide

1. Prepare Your Bike

Ensure your KTM 50SX 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 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

To remove any residue, flush the cooling system with distilled water. Reinstall the drain bolt temporarily, fill the system with distilled water, and run the engine for a few minutes. Turn off the engine and drain the water by removing the drain bolt again.

4. Refill with New Coolant

Once the system is flushed, reinstall the drain bolt securely. Use a funnel to pour the new coolant into the radiator until it reaches the appropriate level. Ensure no air pockets remain by gently rocking the bike and checking the coolant level again.

5. Check for Leaks

Start the engine and let it run for a few minutes. Check for any leaks around the drain bolt and radiator cap. Tighten if necessary.

6. Final Inspection

After the engine cools down, recheck the coolant level and top off if needed. Clean any spilled coolant with a clean cloth to prevent damage to the bike's components.
