Tools and Materials Needed

  • Socket wrench set
  • Funnel
  • Rags or paper towels
  • Safety gloves

Step-by-Step Guide

1. Prepare Your Bike

Ensure the bike is on a stable surface and the engine is cool to prevent burns. Wear safety gloves to protect your hands.

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 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. Clean Up

Wipe any spilled coolant from the bike and dispose of the old coolant responsibly. Check local regulations for proper disposal methods.
