Step-by-Step Guide

1. Prepare Your Bike

Ensure your bike is on a stable surface and completely cool to prevent burns. Remove the skid plate if necessary to access the drain bolt.

Place a drain pan under the engine. Locate the coolant drain bolt on the water pump cover and use a socket wrench to remove it. 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. Gently squeeze the radiator hoses to remove air pockets. Top off the coolant as needed.

6. Final Check

Turn off the engine and let it cool. Check the coolant level and add more if necessary. Ensure all bolts are tight and there are no leaks.
