Step-by-Step Guide

1. Prepare Your Bike

Ensure your bike is on a stable surface and the engine is cool. This prevents burns and ensures the coolant drains completely.

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)

If the coolant is particularly dirty, consider flushing the system with distilled water. Reinstall the drain bolt, fill the system with 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 helps remove air pockets from the system. Check the coolant level again and top off if necessary.

6. Clean Up

Dispose of the old coolant responsibly. Wipe down any spills and ensure all tools are accounted for.
