Tools and Materials Needed

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

Step-by-Step Coolant Change Process

1. Preparation

Ensure the engine is cool to prevent burns. Place the bike on a stable stand to keep it upright. Wear safety gloves to protect your hands from any spills.

2. Draining the Old Coolant

Locate the coolant drain bolt on the water pump cover. Position the drain pan underneath and use a socket wrench to remove the bolt. Allow the old coolant to fully drain into the pan.

3. Flushing the System

To remove any residue, flush the system with distilled water. Reinstall the drain bolt temporarily, fill the radiator with distilled water, and run the engine for a few minutes. Turn off the engine and drain the water by removing the drain bolt again.

4. Refilling 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 and radiator cap.

5. Bleeding the System

Start the engine and let it idle. This helps remove air pockets from the system. Keep an eye on the coolant level and top off if necessary. Once the engine reaches operating temperature, turn it off and let it cool. Recheck the coolant level and add more if needed.
