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 (Optional)

If the coolant is particularly dirty, 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

Once drained, reinstall the drain bolt securely. Use a funnel to 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 for a few minutes. This helps remove any air pockets in the system. Check the coolant level again and top off if necessary.

6. Check for Leaks

Inspect the system for any leaks around the drain bolt and radiator cap. Tighten any loose components if needed.
