Shop parts for your ride now.

Regular coolant maintenance is critical to keep your 2024 Husqvarna FC350 running at the optimal temperature, preventing engine overheating and corrosion in the cooling system. This guide provides step-by-step instructions, plus important model-specific tips, for a seamless coolant change on your FC350.

Tools & Supplies Needed

  • New coolant (OE recommended: blue G11 type, or an approved motorcycle engine coolant)
  • Drip pan or container for old coolant
  • Socket wrench set (8 mm or 10 mm for water pump cover drain bolt)
  • Screwdriver (as needed for shrouds/hoses)
  • Funnel
  • Gloves and safety glasses
  • Clean rags

Step-by-Step Coolant Change

  1. Ensure Safety First
    Make sure the engine is completely cool before starting any work on the cooling system to avoid burns.
  2. Position the FC350 Upright
    Place the bike on a stand so it is level. This ensures a complete drain and proper refill.
  3. Remove Radiator Cap
    Take off the radiator cap to relieve system pressure and allow coolant to flow freely.
  4. Drain the Old Coolant
    Position a drain pan beneath the water pump cover. Locate the coolant drain bolt (commonly found on the right side, lower water pump cover). Remove this bolt and let all coolant drain out.
    Inspect the old coolant for debris, excessive discoloration, or oil contamination–these could indicate deeper maintenance needs.
  5. Flush the System (Optional)
    For best results, flush the system with distilled water to clear out any old coolant or contaminants. Replace the drain bolt and ensure it's torqued to spec (10 Nm or 7.4 lbf ft for M6 bolts on recent models)†.
  6. Refit and Tighten Drain Bolt
    Replace the drain bolt and any sealing washer or O-ring if needed. Torque to specification.
  7. Add New Coolant
    Use a funnel and fill the radiator with fresh coolant slowly to avoid air pockets. Fill to just below the neck of the radiator cap.
  8. Bleed Air from the System
    Gently rock the bike from side to side and squeeze the radiator hoses to release trapped air. Top off as needed.
    On first run, let the bike idle with the radiator cap off until the thermostat opens and bubbles escape. Top off once more before installing the cap.
  9. Reinstall Radiator Cap
    Secure the cap and check for any leaks around hoses or the drain bolt.
  10. Check Coolant Level After First Ride
    Let the bike cool down completely, then re-check the coolant level and top up if needed.

Model-Specific Tips for the 2024 Husqvarna FC350

  • Coolant Type: For 2024, Husqvarna recommends the use of blue G11 coolant or a compatible motorcycle coolant for best results and system longevity†. Mixing types is not recommended.
  • Cooling System Quirks: The FC350 uses a high-efficiency, lightweight cooling system with WP radiators–ensure you inspect hoses for cracking or leaks every service interval.
  • Overheating Prevention: Factory radiators do not have a coolant recovery/overflow tank. For aggressive racing or trail riding, consider adding an aftermarket coolant overflow kit to prevent air pocket formation on rough terrain and protect your engine.
  • Maintenance Frequency: Check your coolant at every major service and change it at least every season or after heavy use, even if you haven't reached the typical hour interval.

† Always verify torque specifications in your FC350 owner's manual for your exact model year.

Final Checks

  • Proper disposal: Never pour old coolant down a drain. Dispose responsibly at a local recycling center.
  • Inspect other cooling components (cap, hoses, clamps) for wear each time you change your coolant.
  • If unsure, contact your MotoSport dealer or trusted mechanic for advice–protecting your engine starts with regular, high-quality maintenance.

Maintaining your 2024 Husqvarna FC350's cooling system not only preserves performance but protects your investment for every ride.
