How to Change Coolant on a 2010 Beta 520 RR: Step-by-Step Guide

Shop parts for a 2010 Beta 520 RR Dirt Bike.

Changing the coolant in your 2010 Beta 520 RR is essential maintenance to keep your engine running cool under tough off-road conditions. The Beta 520 RR features a reliable cooling system, but neglect can lead to overheating, decreased performance, and costly repairs. Follow these proprietary MotoSport instructions for a safe and thorough coolant change.

Prepare Your Bike – Safety First

  • Ensure the engine is completely cold before starting. This prevents burns and ensures accurate coolant level readings. Always allow extra time for the radiator and engine to cool after any ride.
  • Work in a well-ventilated space–coolant is toxic and should be handled responsibly.
  • Wear gloves and safety glasses.

Required Tools & Supplies

  • Screwdriver and socket set (to access radiator cap and drain plug)
  • Catch pan for old coolant
  • Pre-mixed coolant suitable for motorcycles (consult owner's manual for recommended type)
  • Funnel for pouring new coolant

Step 1: Drain the Old Coolant

  • Locate the radiator cap (usually top left or right of the radiator). Remove the radiator guard if needed.
  • Unscrew the radiator cap slowly and set it aside.
  • Find the drain screw at the base of the water pump or lowest radiator junction point. Place a pan underneath.
  • Loosen the drain screw and allow all coolant to drain completely.
  • Dispose of used coolant in accordance with local laws–never pour it on the ground or down a drain.

Step 2: Flushing (Recommended)

If old coolant was heavily discolored or contaminated, flush the system with distilled water.

  • Replace drain screw, fill system with distilled water up to recommended level (10 mm above radiator fins when cold).
  • Run the engine briefly until warm, then shut down and allow to cool completely.
  • Drain the water and repeat as needed.

Step 3: Fill with New Coolant

  • Tighten the drain screw securely.
  • Pour new coolant slowly through the radiator filler neck until it covers the radiator fins by about 10 mm when the engine is cold. The system capacity for the Beta 520 RR is approximately 1–1.3 liters.
  • Give the bike a gentle rock to help the coolant settle and dislodge air bubbles. This step is crucial for the effective bleeding of the cooling system in Beta bikes—bleeder screws are not present in the 2010 model.
  • Top off coolant if level drops below the fins.

Step 4: Bleed and Final Check

  • Replace the radiator cap.
  • Start the engine and let it reach full operating temperature (until the fan cycles on and off if equipped).
  • Turn off and allow the engine to cool completely.
  • Recheck coolant level; add more if required until it again sits about 10 mm above the radiator fins.

Beta 520 RR: Owner's Tips & Model Notes

  • This bike’s cooling system lacks radiator bleeder screws found on some older or newer Beta models.
  • Checking the coolant level must always be done cold. The correct level is just above the radiator fins—do not overfill.
  • Inspect the radiator hoses for cracks and leaks during coolant changes, as off-road vibration is tough on them.
  • Annual coolant replacement is recommended by many Beta owners for optimal performance.
  • Use only motorcycle-specific, pre-mixed coolant for best protection and compatibility with system components.

Environmental & Safety Reminders

  • Coolant is toxic—always keep out of reach of children and pets.
  • Never open the radiator cap when the engine is hot to avoid serious burns.
  • Properly dispose of old coolant at designated waste facilities.
