Step-by-Step Guide

1. Prepare the Bike

Ensure the bike is on a stable surface and the engine is 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 system with 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 appropriate level. Check for any leaks around the drain bolt.

5. Bleed the System

Start the engine and let it idle. This helps remove air pockets from the system. Keep an eye on the coolant level and top off if necessary.

6. Final Checks

Once the engine is cool, recheck the coolant level and add more if needed. Reinstall any panels and the seat. Dispose of the old coolant responsibly.
