Keeping your 2014 Husaberg FE501 running cool and protected requires regular coolant changes. This step-by-step guideunique to MotoSport.comdetails how to properly drain, flush, and refill coolant, along with special model notes so your MMY dirt bike stays in top condition for every ride.

Tools – What You Need

  • Fresh coolant (consult your manual for type; silicone-based coolant is often preferred for European four-stroke models)
  • Drain pan
  • Sockets or wrenches (8mm or similar for drain bolt)
  • Gloves – for protection
  • Funnel
  • Distilled water (for flushing)
  • Rags for cleanup

1. Bike Prep – Get Ready to Service

  • Let the engine fully cool – the radiator system operates under pressure and high heat, so NEVER open the radiator cap on a hot engine.
  • Stand the bike upright on level ground or a stand for easy access to both sides of the frame.
  • Remove the right side panel if needed to access the radiator cap and upper radiator area.

2. Relieve Pressure & Remove the Radiator Cap

  • Slowly loosen the radiator cap to relieve pressure in the system.

3. Locate and Remove the Coolant Drain Bolt

  • On the 2014 FE501, the coolant drain bolt is typically found on the right side of the engine casing, directly below the water pump area.
  • Place your drain pan under the bolt.
  • Remove the bolt and let old coolant flow into the pan. Be sure to also loosen any bleed screws at the top of the radiators for faster draining (if equipped).

4. Flush (Recommended for Best Results)

  • After draining, reinstall the drain bolt (with a new sealing washer if available to prevent leaks).
  • Fill the system with distilled water (not tap water).
  • Run the engine briefly (30-60 seconds) to circulate.
  • Turn off the engine and repeat the drain process.
  • Flushing helps remove scale or debris from the entire cooling circuit.

5. Refill with New Coolant

  • Install the drain bolt securely.
  • Use a funnel to fill the radiator slowly with fresh coolant.
  • Capacity for the FE501 is approximately 1.2 liters. Fill to the bottom of the filler neck and allow air bubbles to escape.

6. Bleed Air from the System

  • "Burp" the system by gently rocking the bike side to side or squeezing the radiator hoses to help release trapped air bubbles.
  • Top off coolant level to the filler neck if it drops after air is released.
  • Install the radiator cap securely.

7. Final Steps

  • Run the bike with the cap on until the engine reaches operating temperature. Shut it off and let it cool.
  • Re-check the coolant level and top off if necessary.
  • Look over the system for leaks, especially at the drain bolt and hose connections, before reinstalling body panels.

2014 Husaberg FE501 Model-Specific Notes

  • This model shares much engine layout with KTM and Husqvarna 500cc Enduro four-strokes, so general coolant procedures overlap.
  • Your FE501 features twin radiators – ensure both drain and refill properly.
  • Coolant leaks from water pump seals or hoses are not uncommon on high-mileage bikes. Inspect O-rings, hoses, and clamps during service; replace parts if needed.
  • Always use a coolant type recommended for magnesium engine casings, as found on your FE501, to prevent corrosion or premature wear.
  • If the bike overheats easily or if the fan runs excessively, consider a radiator fan kit or high-performance coolant for additional protection.

Regular coolant changes are an easy way to prevent overheating and corrosion and keep your Husaberg FE501 ready for every adventure. For all replacement hoses, drain bolts, or fresh coolant, MotoSport.com has everything you need.
