Step-by-Step Guide

1. Prepare the Bike

Ensure the bike is on a stable surface and completely cool to avoid burns. Remove the seat and fuel tank to access the radiator cap.

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.

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

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 and radiator cap.

5. Bleed the System

Start the engine and let it idle for a few minutes with the radiator cap off to allow air bubbles to escape. Top off the coolant if necessary and replace the radiator cap.
