Step-by-Step Guide

1. Prepare Your Bike

Ensure your bike is on a stable surface and the engine is cool. Wearing safety gloves, remove the seat and any panels necessary to access the radiator cap.

2. Drain the Old Coolant

Place a drain pan under the radiator drain bolt. Using a socket wrench, carefully remove the drain bolt and allow the old coolant to fully drain. Be sure to dispose of the old coolant responsibly.

3. Flush the System (Optional)

If desired, flush the cooling system with distilled water to remove any debris or old coolant residue. Reinstall the drain bolt and fill the system with distilled water, then run the engine briefly before draining again.

4. Refill with New Coolant

Once the system is drained, 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 for a few minutes. This will help remove any air pockets in the system. Check the coolant level again and top off if necessary.

6. Reassemble and Test

Reinstall any panels or the seat that were removed. Take your bike for a short ride to ensure everything is functioning correctly and check for leaks once more.
