Step-by-Step Guide

1. Prepare Your Bike

Ensure the bike is on a stable surface and the engine is cool. Wearing gloves and safety goggles is recommended to protect against spills.

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 appears 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 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.
