Routine coolant changes are crucial to keeping your 2019 Husqvarna TE250i running at peak efficiency and preventing costly engine damage. Whether you ride hard on the trails or keep it casual, proper cooling system maintenance protects your investment and ensures consistent performance. Here's a detailed, MotoSport-exclusive guide to changing the coolant in your TE250i, with essential owner tips specific to this model.
Tools & Supplies Needed
- Fresh coolant (engine-appropriate, premixed or concentrate as recommended by Husqvarna)
- Drain pan
- Socket set or T-handle wrenches
- Flathead screwdriver or pliers (for hose clamps)
- Clean rags
- Funnel
- Crush washer (recommended: replace the washer on the drain bolt for best sealing)
- Safety gloves & eye protection
Steps to Change the Coolant
-
Ensure the Bike is Cool
Never attempt to open the cooling system or drain coolant while the engine is hot to avoid burns or injury. -
Remove the Skid Plate (if equipped)
This allows full access to the water pump and drain bolt area. -
Open or Remove the Radiator Cap
Slowly open the radiator cap to release any pressure. Do this with the bike upright. -
Locate & Remove the Coolant Drain Bolt
On the TE250i, the drain bolt is typically on the water pump housing (right side of the engine). Place your drain pan below, then loosen and remove the bolt. Allow coolant to fully drain.
Replace the crush washer on the bolt before reinstalling, then torque the bolt according to your service manual for proper sealing. -
Disconnect Radiator Hoses (Optional Deep Clean)
For a more thorough flush, loosen the hose clamps and carefully pull off the lower radiator hoses. Tilt the bike from side to side to release trapped coolant. -
Flush with Clean Water (if desired)
Fill the radiator with distilled water, reinstall cap, run the engine briefly, then repeat steps 3-5 to help clear any residual coolant and dirt from the system. -
Refill with Proper Coolant
Once draining is complete, reattach hoses and drain bolt. Use a funnel to fill the radiator with fresh coolant, up to the bottom of the filler neck. -
Bleed Air from the System
Rock the bike gently or squeeze the hoses to help remove any trapped air bubbles. Continue topping off as the level drops. -
Secure the Radiator Cap
Replace the cap firmly once your level is correct. -
Start & Warm Up
Run the engine for several minutes, then shut it off and allow it to cool. Re-check and top up coolant if needed.
Key TE250i-Specific Tips & Maintenance Notes
- This model uses electronically controlled fuel injection (TPI) – minimizing risk of overheating compared to traditional carbureted two-strokes, but steady coolant flow is still vital for sensor and injector reliability.
- Coolant loss is often the first sign of radiator or hose wear. Carefully inspect all hoses and radiator seams for leaks, especially during coolant changes.
- Follow the recommended maintenance interval for coolant changes, usually every two years or as indicated by your riding conditions (mud, sand, racing may require more frequent changes).
- Clean and check the oil pump screen every 40 hours, as oil delivery is critical to this model's longevity.
- Dispose of used coolant responsibly – most coolants are toxic to people, pets, and the environment.
