Shop parts for a 2022 Beta 350 RR-S Dirt Bike.
The 2022 Beta 350 RR-S stands out for its blend of enduro performance and street-legal flexibility. Changing the coolant is a critical maintenance task that keeps your engine operating at optimal temperature, safeguards internal components, and extends the life of your bike. The following guidedesigned specifically for MotoSport customersdetails the steps and safety tips you need to ensure your 350 RR-S runs strong on every ride.
Before You Start: What Owners of the 2022 Beta 350 RR-S Should Know
- Always change coolant with the engine completely cold to avoid burns.
- The 2022 Beta 350 RR-S does not have traditional radiator bleeder screws on top of the right radiator as earlier models did; air must be purged using the fill-and-rock method.
- Only use the manufacturer-recommended coolant as specified in your owner's manual.
- Keep coolant away from skin, eyes, clothing, and out of reach of children. If contact occurs, rinse or wash the area thoroughly. If ingested, seek medical help immediately.
Tools & Supplies Needed
- Coolant specified for the Beta 350 RR-S
- Socket or wrench for drain bolt (with correct torque spec; 10 Nm)
- Drain pan
- Protective gloves & clothing
- Funnel
- Rags/towels for cleanup
Step-by-Step Coolant Change Procedure
- Position the Bike
Place the 350 RR-S in a vertical position on level ground, using a stand if possible. - Remove the Radiator Cap
With the engine completely cool, slowly unscrew and remove the radiator cap. Never open the system when hot – pressure and scalding coolant can cause severe injury. - Drain the Old Coolant
Place a suitable catch pan under the water pump area. Locate and remove the coolant drain bolt (usually on the lower part of the right crankcase cover or water pump housing). Allow coolant to drain fully. Inspect the copper crush washer, replacing it if damaged. - Reinstall the Drain Bolt
Refit the drain bolt with washer and torque to 10 Nm to ensure a tight, leak-free seal. - Add New Coolant
Using a funnel, slowly pour in the recommended coolant until it reaches the base of the radiator filler neck (level just above the radiator cores/fins). This model uses a fill-and-rock method to remove air: - Bleed Air from the System
Gently rock the bike from side to side to help trapped air escape. Observe the coolant level; as bubbles emerge and the level drops, keep topping off the coolant to maintain the fill at the radiator neck. - Reinstall the Radiator Cap
Once the coolant no longer drops, replace and securely tighten the radiator cap. - Heat Cycle the Engine
Start the bike and let it idle until it reaches normal operating temperature (wait until cooling fan cycles on if equipped). Let the bike cool completely back to ambient temperature. - Final Coolant Level Check
Reopen the radiator cap and check the level. Top up if needed, and also check the overflow reservoir to ensure it is within the correct range mark. Repeat the fill-and-rock method if needed to release any remaining air pockets.
Key Notes for the 2022 Beta 350 RR-S
- Regularly check coolant level every ride. This model does not have a separate radiator bleed screw, so careful air removal is important on refill to prevent overheating.
- If you notice repeated drops in reservoir levels after rides, check for external leaks or possible head gasket issues.
- Inspect hoses, clamps, and the radiator for damage or agingreplace any suspect parts using MotoSport's Beta-specific catalog.
Safe Disposal
Properly dispose of used coolant at a local recycling or hazardous waste center. Never pour it on the ground or down household drains.
Why Coolant Change Matters
Routine coolant changes remove corrosion, scale, and contaminantspreserving water pump seals, the thermostat, and cylinder head gaskets for reliable off-road and dual-sport adventures.
