Proper coolant maintenance is essential for the longevity and performance of your 2015 Beta 350 RR. Neglecting old or contaminated coolant can lead to overheating, poor engine performance, or even damage. Our MotoSport guide provides detailed instructions specific to your Beta dirt bike model to ensure both ease and accuracy during your next coolant change.
Why Regular Coolant Replacement Matters
- Protects your engine from corrosion and overheating.
- Sustains optimal temperature during demanding rides.
- Preserves water pump and seal integrity in Beta models, which helps prevent leaks or premature wear.
What You Will Need
- New coolant (use the type and brand recommended in your owner manual)
- Drain pan
- 8mm and 10mm socket and wrench set
- Funnel
- Protective gloves and eyewear (coolant is toxic–handle with care)
- Clean rags
Step-by-Step Coolant Change Guide
-
Let the Bike Cool Completely
Only work on the cooling system when the engine is fully cold.
– Never remove the radiator cap on a hot engine—pressurized coolant can cause burns. -
Remove Plastic Shrouds (If Necessary)
For easier access to the radiator cap and drain bolts, loosen or remove the side shrouds. -
Drain the Coolant
- Stand the bike upright, not leaning on a stand, so the system drains evenly.
- Place the drain pan beneath the water pump/fill area.
- Unscrew the radiator cap (located at the top of the right radiator).
- Locate and unscrew the main coolant drain bolt (usually on or near the water pump cover)–refer to your owner's manual for the exact position.
- Allow coolant to drain fully. If equipped with a secondary drain bolt on the cylinder, remove it as well for a more thorough flush.
-
Inspect and Refit Drain Bolts
Check sealing washers for wear–replace if necessary. Reinstall and torque the bolts to spec (typically around 10Nm) once draining is complete. -
Refill the Cooling System
- Only use the coolant type specified for Beta motos (see your manual's recommended lubricants and liquids table).
- Use a funnel and fill the radiator until the coolant level is just above the core, with the bike perfectly upright.
-
"Burp" the System
- With the radiator cap off, gently rock the bike side to side. This helps trapped air escape.
- Top up coolant as needed until fluid stays consistently above the radiator core.
- If your Beta has an overflow reservoir, fill it between the MIN and MAX marks.
-
Secure Radiator Cap
Confirm coolant is at the right level, then reinstall the radiator cap securely. -
Warm Up & Final Top-Off
- Start the engine and let it idle for a few minutes, then shut off and allow to cool.
- Re-inspect coolant level, topping off if needed, as any remaining air may have purged.
-
Dispose of Old Coolant Responsibly
Place it in a sealed container and take it to a certified recycling/disposal facility. Never dump coolant–it's harmful to the environment and pets.
Special Notes for the 2015 Beta 350 RR Owner
- The 350 RR uses a specific coolant volume–refer to your manual, as overfilling can cause overflow or system stress.
- No bleeder screw is present on models from this vintage–proper rocking and filling technique are crucial for air removal.
- Beta's aluminum radiators are efficient but sensitive to water quality. Only use distilled or the premixed coolant recommended by Beta to avoid mineral scaling.
- Flush and replace coolant annually, or more often if frequently exposed to mud, sand, or racing environments.
- When checking the coolant, always do so with the bike upright and engine cold for the most accurate reading.
