Changing the coolant in your 2017 Husqvarna FE250HQ keeps your engine running cool, efficient, and protected from overheating, especially under rigorous off-road conditions. Follow this exclusive MotoSport.com guide for a reliable coolant change, plus model-specific insights for your FE250HQ.

Why Coolant Replacement Matters for the FE250HQ

Your Husqvarna FE250HQ features a liquid-cooled four-stroke engine, demanding effective coolant for optimal performance and protection. Over time, coolant deteriorates, losing its ability to dissipate heat and prevent corrosion inside the radiator and water passages. Routine coolant replacement extends the life of sensitive engine components and preserves top performance in harsh riding environments.

What You Need

  • Fresh, high-quality motorcycle coolant (avoid automotive coolants that may harm engine seals)
  • Drain pan
  • Socket or wrench for radiator and drain bolts
  • Distilled water (for flushing, if desired)
  • Funnel
  • Rubber gloves and shop rags
  • New drain bolt crush washer or sealing washer (recommended)

Step 1: Preparation

  • Ensure the bike is on a stable stand and the engine is completely cool to avoid scalds from pressurized coolant.
  • Remove the right shroud or panel if needed for easy access to the radiator cap and drain bolt.

Step 2: Draining the Old Coolant

  • Locate the radiator cap and slowly loosen it to release residual pressure.
  • Place a drain pan underneath the water pump or lower radiator hose area on the right side of the engine.
  • Remove the coolant drain bolt (consult your service manual, usually at the water pump cover base).
  • Allow coolant to fully drain from the system, including the overflow reservoir if equipped.

Step 3: Optional System Flush

  • To remove stubborn residue, reinstall the bolt and fill the radiator with distilled water.
  • Start the engine briefly (30–60 seconds), then repeat the drain process. Repeat until water runs clear.

Step 4: Refitting and Filling with New Coolant

  • Install a new sealing washer on the drain bolt. Reinstall bolt and torque to spec for a leak-free seal.
  • Pour new, pre-mixed coolant into the radiator using a funnel, filling to the top of the filler neck.
  • Fill the overflow reservoir to the "Full" line if equipped.

Step 5: Bleeding Air from the Cooling System

  • Leave radiator cap off. Start the engine and briefly run it to circulate coolant—gently rock the bike side to side to free trapped air.
  • Watch for bubbles as air escapes. Top off coolant as the level drops.
  • Once the level stays constant, shut off the bike, refill to the neck, and fit the radiator cap securely.

Step 6: Final Checks

  • With the engine fully cooled, recheck and top up the radiator and reservoir if needed.
  • Inspect for leaks at the drain bolt, hoses, and the radiator cap.

Model-Specific Tips for the 2017 Husqvarna FE250HQ

  • The FE250HQ's compact radiator design makes airflow crucial. Always keep radiator fins clear of mud and debris.
  • For aggressive riding or hot climates, consider a performance coolant to maximize heat transfer and minimize boil-over risk.
  • The radiator fan may kick on during extended idling or low-speed technical riding–this is normal and signals proper temp management.
  • Always use coolants approved for aluminum engines to prevent internal corrosion and gasket failure.

Safe Disposal of Old Coolant

Used coolant contains toxins–never pour it down a drain or onto the ground. Bring it to your local automotive recycling center or retailer for safe, environmentally friendly disposal.

Keep Your FE250HQ Running Strong

Regular coolant changes not only safeguard your engine but prevent costly mid-ride overheating. By following this MotoSport guide, you ensure your 2017 Husqvarna FE250HQ stays adventure-ready, season after season.
