How to Change the Coolant on a 2013 Beta 400 RR

Shop parts for a 2013 Beta 400 RR Dirt Bike.

Routine coolant changes are key for keeping your 2013 Beta 400 RR running efficiently – overheating can shorten engine life and ruin performance, especially for enduro models like the 400 RR that tend to see heavy use. Follow this step-by-step MotoSport guide to flush, refill, and burp the cooling system with confidence. Owners of the Beta 400 RR should note the system capacity and never use tap water in the coolant mix, as mineral deposits can damage delicate radiator fins and restrict cooling efficiency.

Prep – What You Need

  • Pre-mixed motorcycle coolant (Beta recommends ethylene glycol-based, silicate-free)
  • Distilled water (if mixing from concentrate)
  • Catch container for old coolant
  • Basic hand tools (Allen keys, screwdrivers)
  • Clean rag
  • Motorcycle stand (optional but safer)

1. Let the Engine Cool Down Completely

Changing coolant on a hot engine is dangerous — never unscrew the radiator cap while the engine is hot or even warm. Always wait until the engine and radiators are cold to the touch before starting the service.

2. Locate the Radiator Cap & Drain Bolt

  • Remove any body panels obstructing access to the radiator cap and radiator bottom drain bolt.
  • Cap A is the filler cap, typically on the left radiator. The drain bolt is usually found at the bottom of the radiator or water pump housing.

3. Drain Old Coolant

  • Place your catch container under the drain bolt.
  • Loosen the drain bolt and let the old coolant flow out completely.
  • If equipped, open the bleeder or overflow screw to ensure a faster drain and remove any leftover coolant in hoses.
  • Dispose of old coolant at an approved recycling center — never dump it down the drain.

4. Inspect Hoses & Seals

  • Now is the ideal time to inspect hoses for cracks, bulges, or oil contamination.
  • Check the integrity of sealing washers on bolts – replace if damaged to avoid leaks.

5. Reinstall Drain Bolt & Pour in Coolant

  • Secure the drain bolt and any overflow screw snugly.
  • Pour pre-mixed coolant (or properly mixed concentrate/distilled water) into the radiator until fluid level sits 10 mm above the radiator fins as specified for Beta RR models.
  • Beta specifies a coolant circuit volume of about 1.0 to 1.3 liters – always confirm with your particular model specification.

6. Burp the System – Remove Air Bubbles

  • Start the engine with the radiator cap off.
  • Let it run several minutes at idle, gently blipping the throttle a few times to free trapped air.
  • Watch the fluid level – as air escapes, you may need to top off again.
  • Shut the engine down and allow to cool fully. Check the coolant level again; refill if needed.
  • Replace the radiator cap securely once fluid is stable at the proper height.

7. Final Checks

  • Confirm no leaks are present at the drain bolt, hose connections, or radiator cap.
  • Reinstall any removed bodywork.
  • Ride the bike, then let it cool completely and re-check coolant level one last time to ensure proper air purging.

2013 Beta 400 RR Owner Notes

  • This model has a robust cooling circuit but is sensitive to low coolant levels due to its high-revving engine and relatively compact radiator layout.
  • Never mix coolants – always flush thoroughly when switching types, and do not use automotive coolant brands containing silicates or phosphates.
  • If you repeatedly notice the coolant reservoir dropping after multiple rides, check for leaks in hoses, the water pump seal, or the radiator cap.
  • Annual coolant changes are highly recommended for regular off-road use; more frequent service may be needed if racing or riding in harsh climates.

Keep your 2013 Beta 400 RR dirt bike cool & reliable on every ride with the right tools, attention to detail, and genuine MotoSport parts.
