Maintaining the cooling system of your 2001 Husaberg FE400 is essential for optimal performance and engine longevity. This guide from MotoSport covers the complete coolant change procedure for your FE400, along with model-specific notes all owners should know.
Essential Notes for the FE400
- Competition-Grade Engine: The FE400 is built for high-performance riding, making regular coolant checks and changes especially important to prevent overheating, especially under hard conditions.
- Coolant Mixture: Use a 50–50 mix of distilled water and high-quality antifreeze with a corrosion inhibitor. Never use tap water, as minerals can damage radiator components.
- Service Frequency: If riding hard or in severe conditions, service the coolant system more often than the typical maintenance interval. Always follow the recommended procedures for cooling system service especially before extended or aggressive rides.
Step-by-Step Coolant Change Procedure
- Preparation:
- Allow the motorcycle to cool completely before servicing. Never check or open the radiator cap with the engine hot—serious burns can occur.
- Remove the seat and fuel tank for unobstructed access to the cooling parts.
- Draining Old Coolant:
- Locate the drain bolt on the water pump cover.
- Place a container under the drain hole; attach a small hose if needed to direct the flow into a bottle for clean disposal.
- Open the radiator cap to allow air in as the coolant drains out.
- Flushing (Recommended):
- If old coolant is discolored or has debris, flush the system with distilled water. Replace the drain bolt, fill the radiator, run the engine briefly, then drain again.
- Refilling:
- Install a fresh sealing washer on the drain bolt and tighten securely.
- Fill the radiator to the top of the filler neck with your prepared coolant mix (never use tap water).
- Burping the System:
- Leave the radiator cap off, start the bike, and gently rock it side-to-side while blipping the throttle. This helps release trapped air ("burping").
- Shut off the engine, recheck coolant level, and top up to the filler neck and reservoir upper line as needed.
- Reassembly & Cleanup:
- Reinstall the radiator cap, tank, and seat.
- Check all hoses and connections for leaks.
- Dispose of old coolant responsibly at an appropriate recycling center.
Final Recommendations for 2001 FE400 Owners
- Always use genuine Husaberg parts and gaskets for best fit and durability.
- Inspect radiator and hoses for leaks and damage during every coolant change.
- Monitor the coolant level regularly especially after your first ride following a change.
