Step-by-Step Guide

  1. Preparation:
    • Place your TE450 on a stable stand to keep it level.
    • Ensure the engine is completely cool to avoid potential burns.
  2. Locate the Coolant Drain:
    • The primary drain screw is on the right-hand side of the cylinder, toward the front of the engine. Position your drain pan under this pointthis is the lowest point and drains the cooling system thoroughly.
  3. Draining the Old Coolant:
    • Loosen the radiator cap slowly, allowing any residual pressure to escapenever open when the engine is hot, as coolant can spout out and cause injury.
    • Remove the drain screw and let all old coolant flow into the pan. Tipping the bike gently to the right can help evacuate more fluid.
  4. Flush the System (Recommended):
    • Reinstall the drain screw, fill the radiator with distilled water, run the engine briefly, and then repeat the drain process. This helps remove any residual debris.
  5. Inspection:
    • Carefully look at your hoses and clamps. Replace any that appear cracked, swollen, or hardeneda common wear point on aging TE450s.
  6. Adding New Coolant:
    • Secure the drain screw. Pour the correct quantity of coolant into the radiator until it reaches the base of the filler neck.
  7. Eliminate Air Bubbles:
    • Warm up the engine to operating temperature with the radiator cap off; this helps trapped air escape. Once coolant begins circulating and any bubbling settles, top off the radiator if needed and re-cap.
    • Check for leaks around drain plugs and hoses.
  8. Final Checks:
    • Allow the bike to cool fully, then re-check and top off the radiator and overflow reservoir as needed. After a normal heat cycle, re-check coolant levels during your next ride or maintenance checkpoint.
