How to Change the Coolant in a 2014 Husqvarna TE250

Shop parts for a 2014 Husqvarna TE250 Dirt Bike.

Keeping your 2014 Husqvarna TE250's cooling system in top shape is key for reliable performance, especially during technical off-road riding. Periodically changing the coolant prevents overheating, corrosion, and internal engine damage. The TE250 uses a liquid-cooled system similar to other off-road models, but there are quirks and best practices unique to this specific year – so follow this detailed guide to ensure a smooth, mess-free coolant change and keep your bike dialed for every ride.

Tools & Supplies Needed

  • Fresh engine coolant (check your owner's manual for compatibility – silicate-free, motorcycle-specific coolant is best)
  • Basic socket set or T-handles
  • Drain pan
  • Funnel
  • Distilled water (recommended for flushing)
  • Gloves & shop rags
  • Phillips screwdriver (for radiator shrouds if needed)

Step-by-Step Coolant Change Instructions

  1. Preparation:
    • Ensure the engine is completely cool before starting (hot coolant can cause serious burns).
    • Position your TE250 upright on a stand for best access and level draining.
  2. Remove the Seat and Radiator Shrouds:
    • Pull off the seat for better access if necessary.
    • If shrouds block the radiator cap or drains, remove them with a Phillips screwdriver.
  3. Locate and Open the Radiator Cap:
    • Open the right-side radiator cap slowly to relieve any pressure in the system. This prevents unwanted spray and allows the system to drain fully.
  4. Find and Remove the Drain Bolt:
    • The main coolant drain bolt on the 2014 TE250 is typically found at the lower point of the water pump or the side of the engine case. Place your drain pan underneath, then remove the bolt. Allow all the old coolant to drain completely.
  5. Flush the System (Recommended):
    • For best results, reinstall the drain bolt, fill the radiator with distilled water, start the bike briefly (30–60 seconds), then shut it down and drain again. This helps remove lingering deposits and old coolant. Repeat until the water runs clear.
  6. Reinstall the Drain Bolt:
    • Inspect the drain bolt sealing washer for wear; replace if needed. Reinstall and torque the bolt to spec.
  7. Add New Coolant:
    • Using a funnel, pour new coolant slowly into the radiator until it reaches the base of the filler neck.
    • It may help to rock the bike gently or squeeze the radiator hoses to release trapped air bubbles.
  8. Bleed Air from the System:
    • With the radiator cap off, briefly start the engine and let it run until bubbles stop appearing in the radiator. Shut off the engine, then top off coolant if needed. Reinstall the radiator cap securely.
  9. Final Checks:
    • Wipe away any spilled coolant, reinstall your radiator shrouds and seat.
    • Dispose of old coolant properly – do not pour it down drains or onto the ground.
    • After the first ride, check coolant level in the radiator and overflow reservoir (if present), and top off.

Special Notes for the 2014 TE250 Owner

  • Coolant Type: Husqvarna recommends using high-quality, motorcycle-approved coolant. Avoid automotive coolant with silicates or phosphates, which can damage internal passages and seals.
  • Bleeding Is Critical: The TE250's compact cooling circuit can trap air pockets. Take time to burp the system by rocking the bike, squeezing hoses, and running the engine with the radiator cap off after a refill.
  • Check For Leaks: Regularly inspect all hose connections and the water pump weep hole for leaks, especially after maintenance. Early detection avoids overheating or engine damage.
  • Maintenance Interval: Changing coolant every 1–2 years is recommended, especially if you often ride in muddy or sandy environments or notice build-up in the radiator.
  • Radiator Protection: Consider fitting radiator guards when replacing coolant if you ride in rocky or wooded terrain. The TE250's radiators are exposed and can be damaged easily.

Proper coolant changes ensure your Husqvarna TE250 stays cool under pressure, making sure every ride is as good as your first. Stay on top of your maintenance and tackle any trail with confidence.
