Maintaining your 2019 Beta 350 RR-S ensures top performance and engine longevity, particularly when it comes to cooling system maintenance. This guide details how to change the coolant properly, along with crucial model-specific notes to help you get the job done right.
What You Need
- Fresh, recommended coolant that meets Beta specifications
- Basic hand tools (wrenches, screwdriver)
- Container for old coolant (environmentally safe disposal)
- Protective gloves
- Shop towels or rags
Important Notes for the 2019 Beta 350 RR-S
- Always change coolant with the engine completely cold to prevent burns and damage to engine components. Removing the radiator cap when hot is dangerous.
- Coolant capacity is approximately 1.3 liters, but always refer to your owner's manual for exact figures if unsure.
- Inspect the radiator fins and hoses for damage or leaks during the process to prevent future overheating issues.
- This engine features a bleed screw to help release air after filling.
Step-by-Step Coolant Change Procedure
- Prepare the Bike
Stand the motorcycle upright on level ground. Let the engine cool completely–never begin this procedure on a warm engine. - Remove Engine Casing
Using appropriate tools, remove the engine casing by loosening the mounting screws as shown in the owner's manual. This provides access to key coolant components. - Locate and Remove the Radiator Cap
Unscrew the radiator filler cap carefully. Never open the cap when the engine is warm to avoid pressurized coolant spraying out. - Drain the Coolant
Place a drain pan beneath the engine. Locate the coolant drain screw at the bottom of the water pump or adjacent side cover. Unscrew this drain plug to let old coolant flow into the pan. Some models may have a separate screw for draining the left and right radiators, so confirm with your service manual.
After draining, reinstall the drain screw–use a new washer if required–and torque to the manufacturer's specification (commonly 10Nm). - Flush the System (Optional)
If residue or debris is present, flush the system with distilled water. Reinstall all plugs, add distilled water, run the engine briefly, then drain it again. Repeat if necessary until water runs clear. - Filling with New Coolant
Verify all drain screws are tight. Pour the recommended fresh coolant into the radiator until it reaches the base of the filler neck. Consult your owner's manual for approved coolant type. Take care not to overfill. - Bleed Air from the System
Unscrew the bleed screw on the cylinder head or radiator (location varies) to let trapped air escape as you fill. When coolant starts to flow from the bleed screw without bubbles, re-tighten it. - Reinstall Components
Secure the radiator cap, making sure it is properly tightened. Reinstall the engine casing or protection plate and torque screws as specified. - Heat Cycle the Engine
Start the bike and let it idle until it reaches normal operating temperature (but do not let it overheat). Keep an eye on coolant level and check for leaks. Shut off and allow the engine to cool fully, then check and top off the coolant as needed. - Final Checks
Inspect radiator hoses and clamps. Ensure the coolant reservoir is at the proper level. Dispose of old coolant safely according to local regulations.
Extra Tips for Beta 350 RR-S Owners
- Regularly check for debris blocking radiator fins–clean these gently without bending the fins.
- Always use the manufacturer-specified coolant to prevent internal corrosion, gasket failure, and overheating.
- Keep coolant away from children and pets; it is toxic even in small doses.
Following this guide will help you properly maintain your cooling system and keep your 2019 Beta 350 RR-S running strong for many rides to come.
