Changing the coolant in your 2008 Husqvarna TE250 is a key maintenance step that ensures consistent cooling performance, prevents overheating, and extends the life of your engine. The TE250 features a liquid-cooled, dual-radiator system with an electric fan, so performing a coolant service correctly is vital for reliable off-road performance and to protect critical engine components.

What You'll Need

  • Fresh coolant formulated for aluminum engines
  • Drain pan or suitable vessel
  • Metric socket or Allen wrench set
  • Clean funnel
  • Distilled water (for flushing, if desired)
  • Protective gloves and eyewear

Step 1: Prepare the Bike

  • Position your TE250 in a secure, upright stance using a motorcycle stand. Make sure the engine is completely cool before beginning service.

Step 2: Access the Cooling System

  • Remove both shrouds for access to the radiators if necessary.
  • Locate the right-side radiator cap. Remove it slowly to release any residual pressure.

Step 3: Drain the Old Coolant

  • Place a drain pan under the water pump area on the right side of the engine.
  • On the lower water pump cover, find and remove the drain bolt (typically a small bolt at the 6 o'clock position).
  • Let the coolant drain completely.

Step 4: Flush the System (Optional)

  • If the old coolant appeared dirty or contaminated, install the drain bolt temporarily and fill the system with distilled water.
  • Reinstall the radiator cap and briefly run the engine for a couple of minutes.
  • Let the bike cool, remove the radiator cap, and drain the flush water.
  • Repeat if necessary until the drain water appears clear.

Step 5: Reinstall the Drain Bolt

  • Clean and inspect the drain bolt and washer. Reinstall and torque to specification as per owner's manual guidance.

Step 6: Add New Coolant

  • Using a clean funnel, fill the radiator with new coolant to the bottom of the filler neck. The TE250 requires a high-performance, silicate-free coolant compatible with aluminum.
  • Fill slowly to allow air bubbles to escape. Gently rock the bike side-to-side for maximum air release from the radiators.

Step 7: Bleed the System

  • Start the engine and let it idle for several minutes with the radiator cap off.
  • As the coolant circulates, top off to maintain the level at the filler neck.
  • Once the bike reaches operating temperature, shut it down and let it cool completely. Recheck the coolant level–top off as needed and replace the radiator cap.

Step 8: Check for Leaks & Test Ride

  • Visually inspect around the drain bolt, hoses, and radiator caps for any seepage.
  • Wipe down and start the engine. Watch for leaks during the test ride. Reinspect coolant level after the bike has cooled off completely.

Model-Specific Tips for the 2008 Husqvarna TE250

  • The 2008 TE250 features an electric radiator fan–ensure it cycles on after a full warm-up.
  • Use motorcycle-specific, aluminum-safe coolant only; automotive coolants can damage the system.
  • Double-check the tightness of both the radiator cap and drain bolt—vibration from aggressive riding can work them loose.
  • If you ride in extreme conditions, check coolant level and inspect hoses before every ride.

Routine coolant changes are essential to keeping your Husqvarna TE250 running cool on any trail. As always, genuine and performance parts designed for your bike are available directly from MotoSport.
