Shop parts for a 2017 Beta 500 RR-S Dirt Bike.

Routine coolant changes on your 2017 Beta 500 RR-S aren’t just about maintenance—they protect your engine from overheating, corrosion, and premature wear. Follow this unique MotoSport guide for a thorough and hassle-free coolant service procedure, tailored specifically to the quirks and needs of your Beta.

What You Need

  • New coolant compatible with Beta recommendations (refer to owner’s manual for specifications).
  • Catching pan for old coolant disposal.
  • Socket wrench and appropriate sockets.
  • Replacement washer for drain bolt.
  • Protective gloves and safety glasses.
  • Clean funnel.
  • Shop towels.

Safety & Model-Specific Notes

  • Never open the radiator cap if the engine is warm or hot. Only perform coolant work with the engine completely cold–the system is pressurized and hot coolant can cause severe burns.
  • Wear gloves and eye protection; coolant is toxic to skin and especially dangerous if swallowed.
  • The 500 RR-S uses around 1.1 liters of coolant. Always double check the capacities in your manual and do not overfill.
  • Always use the washer on the drain bolt to ensure a proper seal and prevent leaks.

Step-by-Step Coolant Change

  1. Stabilize the Bike
    Secure the motorcycle in an upright, vertical position. Use a stand if possible to prevent the bike from tipping during service.
  2. Remove the Radiator Cap
    Ensure the engine is cold. Slowly unscrew the radiator filler cap to relieve any residual pressure.
  3. Locate & Remove the Drain Bolt
    Place your catch pan under the water pump area. Then, locate the coolant drain screw (usually on the lower side of one of the engine cases). Remove the drain bolt and allow all used coolant to fully drain.
  4. Inspect and Replace Washer
    Inspect the condition of the drain bolt washer; always install a new washer for best results when reinstalling the drain bolt.
  5. Reinstall Drain Bolt
    Once all the coolant is out, thread in the drain bolt and torque it to the manufacturer’s specification (commonly 10 Nm for Beta 500 RR-S, verify for your specific model).
  6. Refill with Coolant
    Using a clean funnel, slowly pour the specified amount of coolant into the radiator until it’s near the filler neck base. Use only the type/brand recommended by Beta to prevent corrosion and optimize cooling system longevity.
  7. Burp the System
    With the cap off, briefly start the engine and let it idle for 10–20 seconds. Blip the throttle and gently rock the bike side-to-side to dislodge air bubbles. Shut off the bike and top off coolant if needed. Repeat this process up to three times until the level stabilizes at the radiator neck.
  8. Top Off Reservoir
    Fill the overflow reservoir (if equipped) to the correct cold mark. The reservoir works as an expansion tank—expect the level to drop after the first heat cycle as trapped air escapes.
  9. Reinstall Radiator Cap
    Confirm the system is burped and coolant level is correct, then reinstall the radiator cap securely.
  10. Test Run and Final Check
    Run the engine to full operating temperature. Allow the bike to completely cool, then check coolant levels in both radiator and reservoir one final time. Top off as needed and inspect for leaks around the drain bolt and radiator area.

Beta 500 RR-S Owner’s Tips

  • This model’s radiators are relatively exposed. Inspect radiator guards and shrouds for damage during every coolant change—small leaks can become major issues over time.
  • If the cooling fan runs excessively or doesn’t activate at operating temperature, inspect your thermostat and fan switch as part of routine coolant maintenance.
  • Dispose of old coolant properly. Many auto parts stores or recycling centers accept used antifreeze.

A freshly serviced cooling system ensures your Beta 500 RR-S is ready for any throttle-heavy ride or tough terrain. Stay vigilant and repeat this service at least annually, or more frequently for racing and high-heat environments.
