Tools and Materials Needed

  • Drain pan
  • Socket wrench set
  • Funnel
  • Rags or paper towels
  • Safety gloves

Step-by-Step Guide

1. Prepare Your Bike

Ensure your bike is on a stable surface and the engine is cool to the touch. This prevents burns and ensures the coolant is not under pressure.

2. Remove the Skid Plate

Using a socket wrench, remove the bolts securing the skid plate. This will give you access to the coolant drain bolt.

3. Drain the Old Coolant

Place a drain pan under the engine. Locate the coolant drain bolt on the water pump cover and carefully remove it. Allow the old coolant to fully drain into the pan.

4. Flush the System (Optional)

If desired, flush the system with distilled water to remove any residual coolant or debris. Reinstall the drain bolt temporarily, fill the system with distilled water, run the engine briefly, then drain again.

5. 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 the coolant reservoir and fill it to the indicated level as well.

6. Bleed the System

Start the engine and let it idle for a few minutes. This allows air bubbles to escape. Check the coolant level again and top off if necessary.

7. Reinstall the Skid Plate

Once the coolant level is stable, reinstall the skid plate using the socket wrench to secure the bolts.
