Shop parts for a 2016 Husqvarna FC250 Dirt Bike.
Routine coolant changes are crucial for the health and longevity of your 2016 Husqvarna FC250. Not only will fresh coolant keep your bike running cool during intense rides, but it also helps prevent corrosion and protects critical engine components. The FC250 features a compact, high-performance engine that runs hot under pressure – maintaining cooling system integrity is a must for getting the most out of your bike.
Important Safety Notes
- Coolant is toxic – never allow it on your skin or eyes, and keep it away from children.
- If coolant is swallowed or contacts skin or eyes, flush immediately with water and see a doctor if necessary.
- Always change any clothing soiled with coolant immediately.
Tools & Supplies Needed
- 8mm or 10mm socket or wrench (confirm exact size on your water pump cover drain bolt)
- Bucket or drain pan
- New coolant (ensure compatible with aluminum radiators)
- Funnel
- New crush washer/seal ring for water pump cover bolt
Steps to Change the Coolant
- Let the engine cool fully. Never open the cooling system when hot.
- Stand your FC250 upright for even drainage.
- Remove the radiator cap to release system pressure.
- Place a drain pan under the water pump cover (left side of engine).
- Remove the drain screw on the water pump cover. For most models, it's a bolt with a copper washer. Allow all coolant to drain out.
- Install the drain screw with a new seal ring. Torque to manufacturer spec: 10 Nm (7.4 lbf ft).
- Pour in fresh coolant through the radiator fill neck. Use a funnel and fill until just below the base of the neck.
- Reinstall radiator cap securely.
- Start the engine and let it idle to operating temp. As coolant circulates, air bubbles will release – occasionally squeeze coolant hoses to help purge air.
- Allow the engine to cool fully again. Recheck the coolant level and top off as needed. Repeat once or twice if air remains in the system.
Notable FC250 Considerations
- High-output engine & compact radiators mean the FC250 is sensitive to coolant levels. Check before every ride.
- Use only high-quality, compatible coolants – look for those safe for aluminum components.
- Pay attention to seal rings and gaskets when reassembling. Leaks cause rapid overheating and possible engine damage.
Pro Tips
- Replace coolant every 20 operating hours or at minimum once a year. More frequent swaps for racing or high-performance riding help protect your motor.
- If you see repeated low coolant levels or air in the system after purging, inspect for leaks or possible water pump seal wear.
- Always dispose of used coolant safely – never pour it down drains or onto the ground.
Proper coolant maintenance keeps your 2016 Husqvarna FC250 running strong – don't overlook this easy, cost-effective service. For all replacement partsincluding radiators, hoses, caps, and genuine Husqvarna coolantMotoSport has you covered.
