Changing the coolant in your 2013 Beta 300 RR is a key maintenance task to ensure your two-stroke engine runs as intended, providing optimal cooling and preventing internal corrosion or overheating. This step-by-step proprietary MotoSport guide will help you drain the old coolant, flush the system if needed, and refill with fresh coolant specifically suited for your iconic Beta.
What 2013 Beta 300 RR Owners Should Know
- The cooling system uses a pressurized radiator linked to a coolant reservoir. It's essential to monitor both fill points.
- The Beta X-TRAINER series and 300 RR use similar procedures, but some earlier models (2012–2014) have a bleeder screw at the top of the right radiator, while your 2013 model typically does not. Instead, ensure the system is bled properly by rocking the bike and checking both radiator and reservoir levels.
- Beta recommends using coolants specified in the manual—always check the manual for the exact product and capacity for your bike.
Step-by-Step Coolant Change Instructions
- Prepare Your Bike
- Let the engine cool completely for safety.
- Secure the bike vertically on a stand.
- Remove the radiator cap (usually found on the right side).
- Drain Old Coolant
- Locate the coolant drain bolt, usually at the base of the water pump cover on the engine’s right side.
- Place a drain pan underneath the bike.
- Remove the bolt and allow coolant to drain fully.
- If possible, open any radiator bleed screws (most 2013 models will not have these); otherwise, gently rock the bike side to side to help air escape as coolant drains.
- Flush If Needed
- If you want a thorough flush, refill with clean water, start the bike, run it briefly (do not reach full operating temperature), then drain again.
- Refill with Fresh Coolant
- Reinstall drain bolt and tighten to specification.
- Pour in fresh coolant, filling the radiator to just above the internal fins.
- Rock the bike to the right then left to help transfer coolant into both radiators and reduce trapped air.
- Check for visible coolant at the filler neck.
- Top off the coolant reservoir to the proper level.
- Bleed the System
- With the radiator cap off, start the engine and let it idle until warm—this helps air escape.
- Watch the coolant level; add more if it drops.
- When the coolant stabilizes, reinstall the cap.
- After a full heat cycle, let the bike cool and recheck both radiator and reservoir levels, topping off if needed.
- Final Checks
- Inspect for leaks and ensure both caps are properly secured.
- Dispose of used coolant safely according to local regulations.
Additional Tips
- Change the coolant annually or every two years to maintain corrosion protection and cooling efficiency.
- Use only fresh, high-quality coolant mixes approved for aluminum radiators and Beta engines.
- If coolant repeatedly disappears from your reservoir after cycling, check for system leaks or gasket failures.
Own your maintenance—clean coolant means a longer life for your Beta’s power and performance.
