Step-by-Step Guide: Changing Coolant on the 2025 Beta 350 RR X-PRO

  1. Remove the Skid Plate (if equipped):
    Detach the skid plate for easier access to the drain bolt and water pump cover.
  2. Access the Radiator Cap:
    Remove the side panel or shroud as needed. The radiator cap will likely be beneath the right or left panel just above the engine.
  3. Drain the Old Coolant:
    Position your drain pan under the water pump.
    Remove the radiator cap to release pressure.
    Use the correct wrench to remove the coolant drain bolt, found on the lower part of the water pump casing.
  4. Empty the Recovery Tank:
    If the overflow reservoir has old coolant, disconnect the hose at the tank and carefully drain it as well.–2–3
  5. Flush (Optional):
    For best results, flush the system with distilled water and repeat the drain process until the water runs clear.
  6. Reinstall and Secure:
    Replace the drain bolt with its washer, torquing to specification from the service manual.
    Ensure hoses and clamps are secure, with no cracks or tears.
  7. Fill with Fresh Coolant:
    Using a funnel, pour new coolant into the radiator until full.
    Fill the overflow tank to the indicated "Full" level.
  8. Bleed Air:
    Tip the bike from side to side and gently squeeze the radiator hoses to work out any trapped bubbles.
    Reinstall radiator cap.
  9. Warm Up and Top Off:
    Start the engine and let it idle with the radiator cap back on to fully circulate the coolant.
    After a few minutes, shut down and let cool.
    Recheck and top off both the radiator and overflow tank if levels have dropped.
  10. Reassemble Panels & Skid Plate:
    Double-check for leaks and proper fit of all components.

Key Tips Specific to the Beta 350 RR X-PRO
