Maintaining the correct coolant level and fresh coolant is vital for your 2009 Husqvarna TE310. This procedure will walk you through a robust coolant change specifically for this model, focusing on steps, safety, and unique considerations for Husqvarna's cooling system.

Preparation & Safety

  • Allow the engine to cool completely before starting. Opening the radiator when the engine is hot can cause scalding coolant to spray – a substantial burn risk for TE owners.
  • Place the bike on a level stand for optimal draining.
  • Gather tools: 8mm or 10mm socket or driver (for hose clamps), drain pan or vessel, funnel, fresh coolant recommended for the TE310, gloves, and safety eyewear.

Coolant Draining Process

  • Locate a vessel on the left hand side of the cylinder, underneath the coolant hose closest to the crankcase.
  • Loosen the clamp on the lower radiator hose and detach the hose from the engine side. This acts as the main drain point for old coolant.
  • SLOWLY open the cap of the right-hand radiator to relieve pressure and allow coolant to flow out smoothly. Tilting the bike gently to the left optimizes draining.– unique to Husqvarna TE models: the dual radiator system requires careful, slow pressure release.
  • Once draining is complete, reconnect the hose and tighten the clamp securely.

Optional: Flushing the System

  • If the old coolant appeared especially dirty or rusty, you may flush with distilled water before refilling. Simply fill, run the bike briefly, cool, and repeat the drain step above.

Refilling with New Coolant

  • Use only coolants suitable for high-performance aluminum engines – the 2009 TE310 has a sensitive double cooler system and an electric fan.
  • Pour coolant into the right-hand radiator until the level reaches the filler neck base.
  • Start the bike and let it warm up with the radiator cap off. Watch for air bubbles as the thermostat opens (this purges air from the system). Occasionally squeeze the radiator hoses gently to help trapped air escape.
  • Once no more bubbles appear, top off coolant if needed, then install the cap.

Final Checks and Maintenance Tips

  • Double-check all clamp tightness and inspect hoses for cracks or swelling. The TE310's cooling components must remain leak-free to avoid engine seizure.
  • After a short ride, let the engine fully cool and recheck the coolant level, topping off as needed. Always maintain coolant to the recommended level, as even minor losses can impact performance on this model.
  • Inspect the operation of the electric cooling fan unique to the TE model – this can activate with the bike off, so keep clear of blades during work.

Special Notes for 2009 Husqvarna TE310 Owners

  • The TE310 features a dual radiator system with electric fan, so precise coolant care is essential for trail and competition riding.
  • Only use coolants compatible with aluminum radiators – silicate-based coolants or poor-quality mixes may corrode this system.
  • If hoses appear hardened from heat cycling, replace them proactively with new hardware – leaking hoses are a common service point on this generation.
  • Follow Husqvarna's maintenance interval and always monitor for leaks after each coolant service.

With fresh coolant and routine checks, your TE310's motor will stay cool under demanding conditions. MotoSport makes it easy to Shop parts for a 2009 Husqvarna TE310 Dirt Bike.
