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 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.

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 for a few minutes. This helps remove air pockets from the system. Check the coolant level again and top off if necessary.

6. Final Check

Inspect for leaks and ensure the coolant level is correct. Dispose of the old coolant responsibly, as it is toxic and harmful to the environment.
