How to Change the Coolant in a 2016 Beta 250 RR

Shop parts for a 2016 Beta 250 RR Dirt Bike.

Keeping your 2016 Beta 250 RR running cool is essential for both performance and longevity. Regular coolant changes remove old, debris-laden fluid and maintain rust and corrosion protection. Follow this proprietary MotoSport guide for a safe, effective coolant change that suits this popular 2-stroke model.

What to Know About Your 2016 Beta 250 RR

  • Two-stroke design: The Beta 250 RR is a high-performance enduro machine utilizing a 2-stroke engine and a liquid cooling system.
  • No radiator bleeder screws: Unlike older Beta models, the 2016 250 RR does not use radiator bleeder screws; air is purged by carefully rocking and topping off the bike during the refill process.
  • Sensitive to overheat: Regular coolant maintenance is vital to prevent overheating, especially under hard riding or in technical sections.

Items You Will Need

  • Fresh, compatible engine coolant (avoid mixing coolants with different chemistries; Beta recommends ethylene glycol-based with corrosion inhibitors)
  • Drain pan
  • Basic hand tools – mainly a socket or wrench set to remove the radiator cap and lower drain bolt
  • Clean rag and safety gloves

Step-by-Step Instructions

  1. Cool Down & Preparation
    • Make sure the engine is completely cool to avoid burns from hot coolant or steam.
    • Place the dirt bike on a level stand for stability.
  2. Radiator Cap Removal
    • Locate the radiator cap on the left side of the bike. Remove any shrouds if necessary for access.
    • Slowly unscrew the cap to relieve any pressure.
  3. Drain Old Coolant
    • Identify the coolant drain bolt – typically at the lowest point of the water pump cover or near the bottom of the right side of the engine case.
    • Place a drain pan under the bolt, then carefully remove it.
    • Allow all coolant to drain completely. You may gently tip the bike side-to-side to remove trapped fluid.
  4. Inspect & Clean
    • Check the drained fluid for excessive debris or discoloration – this could indicate internal corrosion or contamination that may require further inspection.
    • Wipe off any spilled fluid and inspect the drain bolt and sealing washer for wear.
  5. Reinstall Drain Bolt
    • Secure the drain bolt and torque it as recommended by your Beta service manual (do not overtighten).
  6. Refill New Coolant
    • Using a funnel, add fresh coolant to the radiator until it is level with the bottom of the radiator filler neck.
    • Gently rock the bike side-to-side to purge air, allowing trapped bubbles to escape, especially since the 2016 Beta 250 RR lacks a dedicated bleeder screw.
    • Fill to the recommended level.
  7. Replace Radiator Cap
    • Ensure the sealing surface is clean, then reinstall the radiator cap securely.
  8. Check for Leaks & Bleed Air
    • Start the engine and let it idle briefly. After a minute, shut it down and let it cool.
    • Recheck coolant level; top off as needed, since air may work loose after the first cycle.
  9. Inspect After First Ride
    • After your first ride with new coolant, let the engine cool and double-check the coolant level, topping off if necessary.

Pro Tips Specific to the 2016 Beta 250 RR

  • Do not mix different coolant types – always use the type specified for your Beta 250 RR.
  • Inspect radiator hoses for cracking or leaks during every coolant change. Beta OEM and aftermarket replacements are available if needed.
  • Avoid overfilling, which may cause pressure issues, leaks, or poor coolant flow.
  • If you ever need to access deeper cooling components (water pump, impeller, or clutch cover), refer to your workshop manual for proper disassembly & reassembly procedure.

Environmental Note

Collected coolant is toxic and must be disposed of according to your local hazardous waste regulations. Never pour used coolant down drains, onto the ground, or into stormwater systems.
