Changing the coolant in your 2012 Husqvarna TXC250 is crucial for maintaining optimal performance and preventing overheating. The TXC250 features a liquid-cooled engine with a double radiator setup, so proper coolant maintenance ensures consistent temperature control and engine longevity.

Below is a proprietary step-by-step MotoSport.com guide tailored to your bike.

What You Need

  • Fresh, manufacturer-recommended coolant
  • Basic hand tools (screwdrivers, socket set)
  • Drain pan or suitable container
  • Funnel
  • Protective gloves
  • Clean water (optional, if flushing system)

Preparation

  • Make sure the engine is completely cool to prevent burns.
  • Secure the TXC250 upright on a stand so it is perpendicular to the groundthis ensures accurate draining and refilling.
  • Clean around the radiator cap and drain points to keep debris from entering the system.

Draining Old Coolant

  • Locate the lower radiator hose on the left side of the cylinder. Place your drain pan beneath this area.
  • Loosen the clamp securing the hose to the engine and carefully disconnect the hose–coolant will begin draining immediately.
  • Slowly open the right-hand radiator cap to allow the system to vent and drain completely. Lean the motorcycle slightly to the left as needed to assist draining.
    Note: The TXC250 has a two-position radiator cap–the first click allows you to relieve system pressure safely before fully removing.

Flushing (Optional but Recommended)

  • Reconnect the lower hose and clamp if you choose to flush.
  • Fill the radiator with clean water, replace the cap, and briefly start the bike to circulate water (do not allow the engine to overheat).
  • Shut off the engine, let it cool, and repeat the drain steps above until the water runs clear.

Refilling with New Coolant

  • After ensuring all old coolant and flush water is drained, reconnect and secure the lower hose with its clamp.
  • Pour the recommended coolant into the right-hand radiator using a funnel. Fill until the level is about 0.4 inches above the radiator cells when the bike is upright.
  • Reinstall the radiator cap, ensuring it locks securely.

Burping the Cooling System

  • Start the engine and let it warm up until the thermostat opens (the upper radiator hose will get hot).
  • Rev gently a few times to help air bubbles escape, then shut off the engine.
  • After the bike cools to ambient temperature, remove the cap and check the coolant level. Top off as needed to maintain the correct level.
  • Repeat this check after the next ride, as more bubbles may work their way out.

Final Checks & Tips

  • Inspect all radiator hoses and clamps for signs of aging (cracking, swelling, hardening) and replace if necessary–TXC250 hoses are susceptible to degradation with time, so periodic inspection is essential.
  • Never mix coolant types unless specified. Always use a high-quality product matching Husqvarna's recommendations for aluminum engines.
  • If you see repeated drops in your coolant reservoir level or persistent air bubbles, investigate for possible leaks or gasket failures.
  • Check the coolant level regularly, especially before long or hard rides.

Particular Notes for the 2012 Husqvarna TXC250 Owner

  • The 2012 TXC250 uses a carbureted engine (Keihin FCR-MX 37) and features electric start alongside kick start–ensure cooling system service doesn't interfere with electrical connectors near the cylinder.
  • The double radiator design provides efficient cooling but means you must check both radiators for even fill after service.

Routine coolant replacement not only keeps your 2012 Husqvarna TXC250 running cool and strong, but it also provides a chance to inspect the health of your cooling system components.
