Tools and Materials Needed

Step-by-Step Guide

1. Prepare the Bike

Ensure the bike is on a stable surface and completely cool to prevent burns. Remove the seat and any panels obstructing access to the radiator cap.

2. Drain the Old Coolant

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)

If the coolant is particularly dirty, consider flushing 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 for a few minutes. This helps remove air pockets from the system. Check the coolant level again and top off if necessary.

6. Reassemble the Bike

Replace any panels and the seat. Ensure all tools and materials are cleared from the work area.
