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 into the pan.

3. Flush the System (Optional)

For a thorough clean, flush 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. This allows air bubbles to escape. Keep an eye on the coolant level and top off as necessary.

6. Final Check

Once the engine is cool, recheck the coolant level and add more if needed. Ensure all bolts are tight and there are no leaks.
