How to Change the Coolant in a 2014 Beta 520 RS
Shop parts for a 2014 Beta 520 RS Dirt Bike.
The cooling system on your 2014 Beta 520 RS relies on regular coolant changes to maintain optimal engine temperature and prevent overheating – especially critical for high-performance dirt bikes. Changing coolant is a straightforward process, but Beta models do have quirks worth knowing before you get started.
What Makes the 2014 Beta 520 RS Unique?
- Uses a forced liquid-cooling system with a pump to circulate coolant, which is typical for enduro models. This ensures stable operating temperatures, whether you're trail riding or tackling tough enduro courses.
- The engine and hose arrangement may lead to air pockets, requiring careful bleeding after refill to avoid hot spots and uneven cooling.
- Expect capacity just above one liter – running the engine after refill helps distribute coolant into the hoses and engine for an accurate level check.
Tools & Supplies Needed
- High-quality, pre-mixed motorcycle coolant (never use plain water or car antifreeze)
- Drain pan
- Socket set or wrench (for drain bolt and radiator cap)
- Clean rags
- Funnel
- New radiator cap (optional, if replacing)
Step-by-Step Guide: Changing Coolant
- Make sure the bike is completely cool to safely open the cooling system.
- Remove the seat and side panels as needed for access to the radiator cap and overflow bottle.
- Place the drain pan under the bike. Locate the coolant drain bolt on the water pump (usually on the lower engine right side).
- Remove the radiator cap, then unscrew the coolant drain bolt and allow all old coolant to flow out.
Open the overflow bottle, too, to drain any extra coolant. - Use a clean rag to wipe any residue from the radiator and water pump area. Make sure the drain bolt washer is in good condition before reinstalling and tightening the bolt to factory specs.
- Fill the cooling system with new coolant. Pour slowly to avoid air bubbles. Stop when the coolant reaches nearly the top of the radiator filler neck.
- Reinstall the radiator cap and overflow bottle cap securely.
- Start the bike and let it run for 1-2 minutes. Shut it off, let it cool back down, and recheck the coolant level – add more as needed, since some coolant will circulate and air will escape from the system when the engine first runs.
- Inspect for leaks and make sure the radiator cap is properly seated. Monitor the first few rides for proper temperature and coolant levels in the overflow bottle.
Maintenance Tips Specific to the Beta 520 RS
- Annual coolant flushes are recommended. Some owners flush more frequently if riding in harsh conditions – high heat, mud, or slow technical terrain.
- If your model uses OEM hoses or a plastic overflow bottle, check for aging: replace if brittle or cracked during your coolant change.
- Beta recommends using their approved coolant type to protect magnesium and aluminum engine parts – never substitute with automotive types.
- Monitor idle speed after coolant change, as major temperature shifts can impact idle on carbureted engines. Adjust the idle screw if needed for smooth operation.
- Read up on carburetor float level checks during major maintenance – improper float height may cause cooling system pressure issues over time.
Final Checks
- Double check that all panels, caps, and bolts are secure.
- Monitor coolant level over the next couple rides – topping off is normal as trapped air escapes.
- If you repeatedly lose coolant or see frequent overheating, consider inspecting the water pump seal, radiator hose clamps, or thermostat function (if equipped).
The Beta 520 RS is loved for its reliable power and rugged trail performance – regular coolant changes keep it running cool and strong season after season.
