Keeping the cooling system in top shape is crucial for the longevity and peak performance of your 2006 Husqvarna TE250. Whether you ride trails, race, or explore backcountry terrain, it is essential to periodically flush and replace the coolant to prevent overheating, corrosion, and engine damage. Follow this comprehensive MotoSport-exclusive guide to perform a professional-quality coolant change at home.
What You'll Need
- Protective gloves & safety glasses
- Quality motorcycle coolant (pre-mixed or concentrate, as recommended by Husqvarna)
- Catch pan or suitable vessel for old coolant
- 12mm socket or wrench (for drain screw)
- Distilled water (if flushing or mixing concentrate)
- Shop towels
Model-Specific Considerations
- The TE250 features a double cooler design with an electric fan, optimized for enduro use. Be sure to select a coolant compatible with aluminum radiators and magnesium engine cases to avoid corrosion.
- Always use distilled water–tap water can introduce minerals harmful to your cooling system.
- System capacity is approximately 1.1 liters, but always check your manual or fill to spec using the radiator neck as your guide line.
Step-by-Step Instructions
-
Preparation
Ensure the motorcycle is cool to the touch. Place the bike on a stable stand or level ground. Remove the seat and side panels for easier access to the radiator filler cap and hoses. -
Drain the Old Coolant
Place a catch pan on the right-hand (RH) side of the engine, just beneath the coolant drain screw on the cylinder. Using a 12mm wrench, remove the drain screw and washer.
Slowly loosen and open the right radiator cap to allow the coolant to drain completely. Allow several minutes for the coolant to empty from both the drain and the lower hoses if disconnected. -
Flush the System (Recommended, Especially if Switching Coolant Types)
After initial draining, lightly re-install the drain bolt and fill the radiator slowly with distilled water. Replace the cap and start the engine for 20-30 seconds–do not allow the engine to overheat.
Shut off the engine, allow it to cool, then open the drain bolt and radiator cap to let the flush water escape. Repeat until drained water runs clear. -
Reinstall Drain Bolt
Inspect the drain bolt washer for wear, replacing if necessary. Torque the drain screw to 8 Nm (5.8 ft/lb) to avoid overtightening. -
Fill with New Coolant
Fill the radiator slowly with new coolant up to the base of the neck. Snap the radiator cap back on once filled to spec. -
Burp the Cooling System
Start the engine with the radiator cap off. Let the bike run gently for a few minutes and lightly blip the throttle–this helps release trapped air ("burping" the system). Watch for bubbles. Top off coolant to proper level as needed.
Once bubbling stops, reinstall the radiator cap. -
Final Checks
Reinstall any body panels or guards removed earlier. Inspect the area for leaks near the drain bolt and hoses. Dispose of old coolant responsibly, using an authorized recycling center.
Noteworthy Tips for 2006 TE250 Owners
- The electric cooling fan is a unique feature for this off-road model–always check its wiring and function during regular cooling system maintenance.
- Always inspect radiator hoses for brittleness or swelling and replace as needed. The cooling system's dependability is only as good as its weakest link.
- Use only motorcycle-specific, silicate-free coolant to ensure compatibility with the TE250's aluminum and magnesium components.
- With aggressive off-road use, consider checking coolant level between long rides, as the TE250 works hardest in heat and heavy terrain.
Routine coolant changes are a vital part of maintaining your 2006 Husqvarna TE250—protect your investment, performance, and fun with simple, regular care from the MotoSport team.
