Changing the coolant in your 2016 Husqvarna TE250 is a critical maintenance task that ensures optimal engine performance and protection against overheating. This guide walks you through each step, highlights important model-specific information, and helps you avoid common pitfalls unique to this year and model.

What You'll Need

  • Fresh motorcycle coolant (pre-mixed or concentrated – see notes below)
  • 10mm spanner or socket
  • Drain pan
  • Funnel
  • Clean rags
  • Distilled water (if coolant is not pre-mixed)
  • Protective gloves

Preparation Steps

  • Start with a completely cool engine to avoid burns – hot coolant can cause serious injury.
  • Stand the bike upright on a level surface using a lift stand to keep it stable during service.
  • Remove any bodywork if necessary to access the radiator cap and drain bolt area.

Draining the Old Coolant

  • Locate and slowly remove the radiator cap to release any residual pressure.
  • Find the coolant drain bolt, most commonly on the water pump cover on the right side of the engine.
  • Place your drain pan underneath and loosen the 10mm drain bolt – let all old coolant flow into the pan.
  • For a thorough drain, tilt the bike slightly side-to-side.
  • Inspect the old coolant for unusual colors, oil, or debris, as this can signal internal issues.

Flushing for Best Results

  • If the coolant was especially dirty, flush the system by briefly filling the radiator with distilled water, reinstalling the drain bolt, running the bike for just a minute, and then draining again.

Refilling the Coolant

  • With the drain bolt securely reinstalled (replace the sealing washer if it's worn), pour new coolant into the radiator up to the filler neck.
  • If using concentrate, always mix it with distilled water (typically 50/50). Never use tap water as it introduces minerals and causes deposits in the cooling system.
  • Reinstall the radiator cap.

Bleeding Air and Final Checks

  • Start the motorcycle and let it idle for several minutes with the radiator cap off. Gently rev and rock the bike to help remove air bubbles ("burping" the system).
  • Top off coolant as needed once air has been expelled.
  • Reinstall the radiator cap securely and wipe up any spills.
  • Check the coolant reservoir (if equipped) and fill to the indicated level.

What 2016 Husqvarna TE250 Owners Should Know

  • The 2016 TE250 uses a lightweight, high-performance two-stroke engine with aluminum radiators that are susceptible to mineral buildup. Using the correct, manufacturer-recommended coolant and always mixing with distilled water prevents blockage and corrosion inside the radiators.
  • This model's coolant system is designed to be serviced every 40–50 hours of run time or annually, whichever comes first. Service intervals may need to be shortened if ridden in harsh conditions or in muddy/wet environments.
  • If you notice persistent overheating, inspect for damage or blockages in the radiator fins and ensure all hose clamps are secure after service.
  • Disposing of old coolant safely is critical. Always use a proper collection pan and deliver used coolant to a local recycling center or hazardous waste facility, as coolant is toxic to animals and the environment.

Pro Tips

  • While the process is straightforward, patience when filling and burping the system will ensure no air is trapped – trapped air can cause hot spots and internal engine damage.
  • Perform a test ride after service and monitor coolant levels, topping off if needed after your first cool-down cycle.

Regular coolant maintenance protects both your engine and your riding experience, keeping your 2016 Husqvarna TE250 performing at its best on every trail and track.
