Shop parts for a 2009 Husqvarna TE250 Dirt Bike.
Maintaining your 2009 Husqvarna TE250 means keeping your engine cool under demanding riding conditions. Routine coolant changes are crucial for performance and longevity, especially on this high-revving, race-inspired dirt bike. The following guide provides step-by-step instructions – unique for MotoSport customers – specific to the TE250 platform.
What Makes the 2009 TE250 Unique?
- The TE250 uses an aluminum dual-radiator system designed for enduro demands.
- It features a compact head with a small bleeder port and a cylinder drain bolt, which makes coolant changes a bit different compared to other models.
- Radiator components are tightly packed, so careful disassembly is necessary.
What You Need
- Fresh, motorcycle-specific coolant (avoid car coolants or water alone for corrosion protection)
- Socket set & wrenches
- Drain pan
- Funnel
- Clean rags
- Optional: compressed air for full system flush
Step-by-Step: TE250 Coolant Change
- Allow engine to cool completely before starting. Never remove the radiator cap on a hot engine.
- Secure the bike on a level stand. Ensuring the frame is level helps fully drain the system and makes refilling easier.
- Locate the coolant drain screw – typically found on the right-hand side of the cylinder, near the coolant pump housing. Place a drain pan underneath.
- Remove the drain screw. Open the radiator cap slowly to begin draining the old coolant.
- Let the coolant drain fully. Tilting the bike gently may help evacuate trapped coolant from both radiators.
- (Optional but recommended) Flush the system. Reinstall the drain screw and add distilled water (not tap water) to the radiator, then drain again. For a complete flush – especially when changing coolant types – disconnect hoses and use compressed air to blow out all fluid residues, taking care not to over-pressurize.
- Inspect hoses and clamps. Check for cracks or bulges on the hoses. Replace any worn or damaged parts for optimal reliability.
- Reinstall the drain screw. Ensure it is torqued securely, but do not overtighten.
- Refill with new coolant. Pour coolant into the radiator slowly until it is just below the neck. For the TE250, filling from the top of the radiator and monitoring the small bleeder port on the cylinder head ensures no air is trapped in the system.
- Bleed the system. Briefly crack open the bleeder port on the cylinder head until coolant seeps out with no air bubbles, then tighten it. Continue topping off the radiator as needed to the full mark.
- Reinstall the radiator cap. Start the engine and let it idle for several minutes. Check for leaks at all connections.
- Check the coolant level once more. Allow the engine to cool, then remove the cap to verify the coolant is topped off. Add more if necessary.
Expert Tips for Husqvarna TE250 Cooling System
- Inspect radiator fins and guard: Keep them free of debris for optimal airflow.
- Choose a coolant designed for high-performance motorcycles. This improves heat transfer and helps prevent corrosion in the system.
- Check overflow reservoir levels. Not every TE250 houses an overflow tank, but if yours does, fill to the indicated mark.
- Replace coolant every one to two years, or sooner if you ride in extreme environments or race conditions.
The 2009 TE250 rewards diligent maintenance with steady, reliable performance. If you ever need new hoses, radiators, clamps, or coolant, MotoSport keeps your bike ready for the next ride.
