- Stabilize the bike on a stand. Keep it level to help all the old coolant drain.
- Remove the radiator cap. Loosen it slowly to release any residual pressure.
- Locate the coolant drain bolt. On the TE250i, it is typically on the lower water pump cover at the right engine case.
- Position your drain pan. Place it under the drain bolt before loosening.
- Remove the drain bolt. Allow coolant to drain fully. Inspect the bolt's sealing washer and replace if worn.
- Optional: Flush system. Reinstall the bolt, add distilled water, run the engine briefly (with the radiator cap off), and repeat the draining step to flush contaminants.
- Reinstall the drain bolt. Tighten to manufacturer specavoid overtightening to prevent stripping the threads.
- Refill with coolant. Add coolant slowly using a funnel.
- Bleed the system. The 2023 TE250i includes a small bleed screw or port on top of the cylinder head. Loosen this gently after filling to allow trapped air to escape. Retighten once coolant flows steadily without air bubbles.
- Top off the radiator. Fill to the base of the filler neck; install the cap securely.
- Check operation. Start the engine, let it idle, and check for leaks. The cooling fan (if present) should function properly as the bike heats up. Recheck coolant level after the first ride and top off if needed.
