How to Change the Coolant in a 2013 Husaberg FE501

Shop parts for a 2013 Husaberg FE501 Dirt Bike.

Keeping your 2013 Husaberg FE501 performing at its peak demands regular maintenance–and changing the coolant is one of the most important tasks to ensure optimal engine temperature and longevity. This guide will walk you through a step-by-step proprietary MotoSport process, tailored specifically to your FE501.

What Makes the 2013 Husaberg FE501 Unique?

The 2013 FE501 utilizes a performance-focused liquid-cooled four-stroke engine designed for both agility and reliability in demanding enduro conditions. This model places radiators in an exposed position and features tightly routed hoses. Proper coolant maintenance prevents overheating issues and protects aluminum and magnesium engine components typical for Husaberg builds. Always make sure no dirt enters the open system during the process–the injection system and thermostat are sensitive to contamination.

What You Will Need

  • Silicone or standard coolant hoses (inspect for wear)
  • High-quality dirt bike coolant (1.2L recommended)
  • Drain pan
  • Ratchet, appropriate sockets
  • Rags and gloves
  • Optional: soft bottle brush, distilled water (for flushing)

Step-By-Step Coolant Change Procedure

  1. Preparation:
    • Make sure the engine is completely cool.
    • Park your bike upright on a level stand to allow for full drainage.
  2. Remove the Fuel Tank Spoilers (if needed):
    • Loosen and remove the plastics around the radiator to access the cap and hoses. On the FE501, make sure no wires or cables are trapped.
  3. Open the Radiator Cap:
    • Open the cap slowly to release pressure. Place a rag over it to prevent splashing.
  4. Drain the Old Coolant:
    • Locate the radiator drain bolt, typically at the bottom of the right-side radiator.
    • Place your drain pan under the bolt.
    • Remove the bolt and allow coolant to fully drain. You may need to slightly tilt the bike to get the last ounces out.
  5. Flush the System (Recommended):
    • If coolant appears dirty, flush the radiators and water pump cavity with distilled water. Replace the drain bolt, add water, run the engine briefly, and then drain again.
  6. Inspect the Sealing Ring:
    • Inspect the sealing ring (crush washer) on the drain bolt. Replace if damaged or worn. This helps prevent leaks after reinstallation. Torque the drain bolt to the manufacturer's recommendation (typically 10 Nm).
  7. Refill With Fresh Coolant:
    • Confirm that all hoses are securely attached, then slowly pour fresh coolant into the radiator neck until full (capacity is approximately 1.2 liters).
    • Gently tap or bounce the bike and squeeze hoses to release any trapped air.
    • Wait for any bubbles to escape and top off as needed.
  8. Reinstall the Radiator Cap & Plastics:
    • Reinstall the radiator cap once the coolant level is steady.
    • Reattach tank spoilers and check all fasteners and hose connections.
  9. Warm-Up & Re-Check:
    • Start the bike and bring it up to operating temperature, then shut off and let it cool completely.
    • Re-check the coolant level and top off as necessary.

MotoSport Tips for the 2013 Husaberg FE501 Owner

  • Never let dirt, sand, or metal shavings enter the cooling system during service. The FE501's tight tolerance water pump and compact radiators are easily compromised by contamination.
  • Always use coolants designed for aluminum/magnesium engine components to avoid corrosion.
  • If you consistently ride in extreme temperatures, check hoses and clamps for aging every season–the FE501's layout means hose failure can rapidly lead to overheating.
  • Regularly inspect for leaks at connections after every coolant change.
