Step-by-Step Guide

1. Prepare Your Bike

Ensure your bike is on a stable surface and completely cool before starting. This prevents burns and ensures accurate coolant levels.

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 out.

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. Be sure to use a coolant that is compatible with aluminum engines to prevent corrosion.

5. Bleed the System

Start the engine and let it idle with the radiator cap off. This allows air bubbles to escape. Once the coolant level stabilizes, top it off if necessary and replace the radiator cap.

6. Check for Leaks

Inspect the system for any leaks around the drain bolt and hoses. Tighten any loose connections as needed.
