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.

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 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 appropriate level. Check for any leaks around the drain bolt.

5. Bleed the System

Start the engine and let it idle. This will help remove any air pockets. Keep an eye on the coolant level and top off if necessary.

6. Final Checks

Once the engine is cool, check the coolant level again and add more if needed. Reinstall the skid plate if it was removed.
