Routine coolant changes extend the life of your 2015 Husqvarna FC250, maintain peak engine performance & prevent overheating. Use this proprietary MotoSport guide for a safe, thorough coolant change with model-specific advice.
What You Need
- Fresh coolant (preferably blue G11-type antifreeze, the OE recommendation)
- Socket or wrench set (for drain bolt, 10 Nm torque for reinstallation)
- Funnel
- Catch pan
- Protective gloves & eye protection
- New copper crush washer/seal ring (recommended)
Special Note for the 2015 Husqvarna FC250 Owner
- This model shares much of its engine platform with KTM models, but always use OE-spec coolant (blue G11) to maintain proper corrosion protection and cooling efficiency – mixing types can cause damage to alloy components.
- The factory radiator system is sealed & filled with coolant that should be replaced at recommended intervals for best performance and reliability.
- Never attempt to change coolant with a warm or hot engine to avoid scalding injury.
Step-by-Step Coolant Change Instructions
- Position the Bike
Place the motorcycle upright on a stand to ensure the radiator drains completely. - Let Engine Cool
Confirm the engine is completely cool. Coolant is under pressure when hot and can spray dangerously. - Remove the Radiator Cap
Twist off the radiator cap carefully to release any residual pressure. Set it aside in a clean area. - Place a Catch Pan
Position a catch pan under the engine, directly below the water pump cover, to collect draining coolant. - Drain the Coolant
Locate and remove the water pump drain screw (usually on the lower right side engine case). Allow all coolant to drain out. - Reinstall Drain Screw
If possible, use a new copper crush washer for the drain screw to prevent leaks. Torque the screw to 10 Nm (7.4 lbf ft) as specified by the manufacturer. - Fill with Coolant
Insert a funnel into the radiator neck. Pour OE-spec coolant until the fluid rises just above the radiator fin line, generally about 0.95L (1 US quart) for this model. - Check for Leaks & Bleed Air
Gently rock the bike side to side and tap radiator hoses. Some recommend briefly starting the engine with the radiator cap off, then topping up as trapped air escapes (use care to avoid splashing). Stop engine immediately if coolant begins to boil out. - Final Top-Off & Close
Ensure coolant level is just above the fin line. Reinstall the radiator cap securely.
Clean Up & Disposal
- Wipe any spilled coolant from the frame and engine to prevent corrosion or slippery surfaces.
- Dispose of used coolant properly at your local hazardous waste facility – coolant is toxic and unsafe for the environment.
After Changing the Coolant
- Run the engine fully to temperature, monitoring for leaks and confirming the radiator fans (if equipped) cycle correctly.
- Check coolant level again after engine cools, as air bubbles sometimes settle after initial refill.
Common Questions
- Which coolant should I use? Husqvarna recommends blue G11-spec coolant, but high-performance alternatives like Engine Ice are occasionally used if compatible with aluminum and magnesium engine parts. Do not mix coolant types.
- How often should I change coolant? At least once per year with regular riding, or any time the color appears dirty or if the system was contaminated.
- Can I use tap water to dilute coolant? Use only distilled or deionized water to avoid mineral buildup.
