Step-by-Step Guide

1. Prepare Your Bike

Ensure your bike is on a stable surface and completely cool to prevent burns. Wear safety gloves to protect your hands.

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)

For a thorough clean, flush the system with distilled water. Reinstall the drain bolt, fill the radiator 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 top. Check for any leaks around the drain bolt.

5. Bleed the System

Start the engine and let it idle. As the engine warms up, air bubbles may rise to the top. Add more coolant if necessary to maintain the correct level.

6. Final Check

Turn off the engine and let it cool. Check the coolant level again and top off if needed. Ensure there are no leaks and that the radiator cap is secure.
