Keeping your 2013 Beta 450 RS running at its best requires proper cooling system maintenance. Changing the coolant is essential for optimal performance and engine longevity, especially if you frequently put your dirt bike through tough conditions. Here–s a step-by-step, MotoSport-exclusive guide tailored for this model.
What You–ll Need
- Quality, manufacturer-approved motorcycle coolant
- Drain pan
- Socket set & screwdrivers
- Rag & funnel
- Compressed air (optional for thorough flushing)
- Distilled water (if flushing the system)
- Protective gloves & eyewear
Things to Know about the 2013 Beta 450 RS
- Always check & change coolant with the engine cold to avoid burns.
- The radiator fins should be immersed under about 10mm of coolant when full.
- Typical coolant system capacity (check your manual for specifics): approx. 1.1–1.3 liters.
- If you–ve upgraded hoses or cooling parts, check for air pockets during refilling.
- Many Beta bikes are sensitive to air in the system—proper bleeding and topping off is essential for consistent cooling.
Step-by-Step Coolant Change Process
- Allow bike to cool completely. Never remove the radiator cap when hot—serious burns may result.
- Remove radiator cap. Locate cap A (usually left-side radiator) and unscrew.
- Locate and remove coolant drain bolt. On this model, the drain is usually a bolt at the bottom of the water pump cover. Place your drain pan under the bike.
- Drain old coolant. Remove the drain bolt and allow coolant to fully drain out.
- Optional: Flush the system. If switching coolant types or after heavy use, replace the drain bolt and fill the system with distilled water. Run the engine briefly (with cap on), then repeat the drain procedure. For a more thorough flush, use compressed air to blow out remaining water/coolant from hoses and the radiator by removing main hoses and directing air through the system.
Note: Always reinstall drain bolt before the next steps. - Refit drain bolt and torque to spec. Ensure seal and crush washer are in good condition to prevent leaks.
- Refill with fresh coolant. Using a funnel, fill the radiator until the liquid covers the radiator fins by about 10mm. Do not overfill.
- Bleed the system of air. Squeeze the upper and lower radiator hoses to help bubbles escape. On the 450 RS, gently tilting the bike side-to-side can help burp air pockets upwards.
- Run the engine briefly. With the cap off, start the engine and allow it to idle for 1–2 minutes. Add more coolant if the level drops.
- Recheck and top off. Replace the radiator cap. Let the bike cool completely, then recheck level and add coolant if necessary. After a short ride, repeat the level check, as any remaining air can work its way out.
Tips & Final Checks
- Inspect hoses, radiator, and clamps for leaks while the system is pressurized.
- Use only recommended coolant types—traditional EG (ethylene glycol) coolants or compatible pre-mix, not just tap water.
- A yearly coolant change is ideal for max protection, especially for aggressive or year-round riding.
- Dispose of old coolant at an authorized recycling center—never pour down the drain.
Proper cooling system maintenance prevents overheating, prolongs engine life, and ensures your Beta 450 RS performs at its best on every ride. Stay ahead of scheduled maintenance and trust MotoSport for all your dirt bike needs.
