Step-by-Step Guide

1. Prepare Your Bike

Ensure the bike is on a stable surface and the engine is cool. This prevents burns and ensures safety while working on the bike.

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 appears 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 the owner's manual for the correct coolant capacity.

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. Check for Leaks

Inspect the system for any leaks around the drain bolt and hoses. Tighten any loose connections if needed.
