Shop parts for a 2017 Beta 350 RR-S Dirt Bike.
Changing coolant on your 2017 Beta 350 RR-S is part of essential maintenance that ensures optimal engine cooling and protects against corrosion, especially when you ride in harsh off-road conditions. Due to the design and requirements unique to the Beta 350 RR-S, this guide walks you step-by-step through the process while flagging specific tips important for your model.
Important Safety Reminders
- Always work on a completely cold engine. Never remove the radiator cap on a hot engine–hot coolant can cause severe burns.
- Wear gloves and safety glasses to protect against chemical exposure.
- Dispose of old coolant responsibly; it's toxic to people and wildlife.
What You Need
- Fresh premixed engine coolant (see your manual for type & volume; typical fill for 2017 Beta 350 RR-S is just over 1 liter)
- Socket set/Allen wrenches for fairing removal
- Drain pan
- Clean funnel
- Rags for spills
Procedure: Step-by-Step
- Access the coolant system: Place the bike on a stable, level surface and use a stand. Remove the engine casing or skid plate by loosening the indicated screws.
- Open the radiator cap: With the engine cold, slowly and carefully remove the radiator filler cap to relieve any pressure.
- Drain the old coolant: Place a drain pan under the water pump area. Locate the coolant drain bolt (refer to owner's manual for exact location near the bottom of the right side engine case). Loosen and remove this screw, along with its sealing washer. Allow all fluid to drain out.
- Reinstall the drain bolt: Once drained, reattach the drain screw with a new sealing washer. Tighten to the specified torque (typically 10 Nm for this model).
- Fill with new coolant: Using a clean funnel, pour recommended coolant into the radiator filler neck until the level is visible (right above the fins inside the radiator core).
-
Bleed air from the system:
- On the 2017 Beta 350 RR-S, there may be a dedicated bleed screw. If not, slowly fill and gently rock the bike back-and-forth or side-to-side to help air escape as you continue to top off fluid.
- Check and top off: Reinstall the radiator cap. Start the engine, let it idle until it is fully warm, and then shut it off. Allow the bike to cool completely, then check the coolant level again. Top off as needed to ensure level is correct.
- Reassemble and inspect: Replace the engine casing/skid plate securely. Inspect for leaks from the drain bolt or elsewhere.
Model-Specific Tips for the 2017 Beta 350 RR-S
- This model does not use a radiator cap bleeder screw as older Betas did. Instead, manually rock the bike to help trapped air escape.
- Always use the coolant type recommended by Beta–never fill with plain water or automotive coolant. Beta specifies liquid type and capacity in the owner's manual.
- If you ride aggressively in hot climates or do extended slow singletrack, consider a coolant formulated for higher boil-over protection.
After Maintenance:
- Always recheck coolant level after the first full engine heat cycle and top off if needed.
- Monitor for slow coolant loss–persistent loss may indicate leaks or internal engine issues.
Regular coolant changes will prevent corrosion and keep your 2017 Beta 350 RR-S performing at its best.
