Keeping the coolant fresh in your 2013 Husaberg FE250 is essential for optimal performance and engine longevity. The FE250 uses a compact, race-inspired cooling system similar to KTM's enduro platforms, and following the correct service routine will help prevent overheating and component wear. Here's how to change the coolant on your MMY dirt bike, plus a few model-specific tips to keep your Husaberg running strong.

Tools and Supplies You Will Need

• Fresh motorcycle coolant compatible with aluminum engines (avoid standard automotive coolants)
• Socket set and wrench
• Drain pan
• Funnel
• Clean rags
• (Optional) New copper crush washer for the drain bolt
• Distilled water (for flushing, if desired)
• Protective gloves and eye protection

Preparation

• Ensure the bike is cold before starting. Removing the radiator cap from a hot engine may cause pressurized coolant and steam to escape, risking burns.
• Place the bike securely on a stand and remove both radiator shrouds for better access.

Draining the Old Coolant

• Start with the radiator cap – loosen it to depressurize the system, but don't remove it fully yet.
• Locate the coolant drain bolt on the lower water pump cover (LH side of the engine).
• Position a drain pan beneath the water pump and remove the drain bolt using the correct socket. Remove the radiator cap completely to let air in and speed drainage.
• Let all coolant drain out. For a more thorough flush, tilt the bike gently side-to-side. If you notice debris or a rusty color, you may consider flushing with distilled waterreinstall the bolt, fill with distilled water, run briefly, and drain again before adding new coolant.

Inspect & Replace Parts

• Check the copper crush washer on the drain bolt for flattening or damage. Replace with a new one if necessary to prevent leaks.
• Inspect radiator hoses and connection points for cracking or leaks. Now is the best time to address any visible damage.

Refill with Fresh Coolant

• Install the drain bolt with the crush washer and torque to manufacturer spec (typically around 7–10 Nm). Over-tightening may strip threads.
• Slowly fill the radiator with fresh coolant using a funnel, up to the base of the filler neck. Avoid overfilling; air expansion can push excess coolant out during the first heat cycle.
• On this model, the system capacity is roughly 0.95 liters. Use a high-performance motorcycle coolant suitable for use with magnesium and aluminum engine parts to prevent corrosion and scaling.

Bleeding Air From the System

• To purge trapped air, gently rock the bike side-to-side and tap the hoses. This encourages bubbles to rise into the radiator neck.
• Leave the radiator cap off and briefly start the engine, letting it idle until the thermostat opens and coolant begins to flow. Watch for bubbling. Carefully top off coolant as the level drops.
• Shut off the engine, allow it to cool, and check the coolant level yet again. Add more if necessary.
• Install the radiator cap securely.

Run & Recheck

• Let the engine warm up completely, ideally until the radiator fan cycles on, then shut off and let cool fully.
• After cooling, remove the radiator cap and confirm coolant remains at the correct level. Add if needed. Reinstall the shrouds.

Model-Specific Notes for the 2013 Husaberg FE250

• This model features a pressure-type radiator cap. Always ensure the seal is free of debris and replace if showing signs of age or cracks, as a weak seal can result in loss of pressure and overheating.
• Frequent off-road use may clog the radiator fins with debris. Clean the fins gently with compressed air or a soft brush each service.
• The FE250's engine tolerances are tight—make sure only motorcycle-specific coolant is used to ensure proper protection and compatibility with magnesium cases.
• Check your owner's manual for exact torque specs and any additional bleeding procedures unique to your engine variant.

Final Check

• Inspect for leaks at all joints and below the engine.
• Record the service in your maintenance log. Coolant flushes are typically required every two years, but heavy riding in hot or muddy conditions may necessitate more frequent changes.

Your 2013 Husaberg FE250 is ready for the trail with fresh coolant in the system.
