Maintaining your 2014 Husqvarna FC250 includes regular coolant changes to ensure optimal engine performance and temperature control. The following guide, proprietary to MotoSport, covers every step needed to safely and effectively swap out your coolant, along with tips specific to your MMY (Make, Model, Year) dirt bike.
Tools & Supplies Needed
- Suitable drain pan
- 8 mm socket or wrench
- Fresh, compatible motorcycle coolant
- Funnel (recommended)
- Clean rags
Step-by-Step Coolant Change Procedure
- Ensure Safety First
Make sure the engine is completely cool before starting. Changing coolant on a hot engine can cause burns or engine damage. - Position the Bike Properly
Stand your FC250 upright on a level surface. Avoid leaning the bike on its sidestand as this may prevent complete draining of the coolant system. - Remove the Radiator Cap
Slowly remove the radiator cap to release any pressure and allow for thorough draining. Inspect the cap for any signs of wear or distortion—replace if necessary. - Locate and Remove the Coolant Drain Bolt
Find the drain bolt situated on the water pump cover. On the FC250 (and KTM-based engines), it is typically an 8 mm boltoften identifiable by a copper washer to ensure a proper seal. Place your drain pan under this area before loosening the bolt completely. - Drain the Old Coolant
Allow all coolant to exit into the pan. For maximum drainage, you may gently rock the bike upright. Dispose of the used coolant safely following local hazardous waste regulations. - Optional: System Flush
For thorough maintenance or if switching coolant types, use distilled water to flush the system. Pour it into the radiator and reinstall the drain bolt, then run the engine briefly and drain again to remove remnants of old coolant. - Reinstall Drain Bolt
Reinsert and snug the drain bolt by hand first to avoid any possibility of cross-threading, then tighten securely with your wrench. Ensure the copper washer is undamaged and properly seated. - Refill with Fresh Coolant
Using a funnel, fill the radiator with fresh, compatible coolant up to the recommended level. Husqvarna recommends a high-performance coolant suitable for aluminum radiators. Fill slowly to allow air to escape and prevent bubbles. - Bleed Air from the System
Some FC250 models feature a small air bleed screw on the radiator; crack it open briefly during filling until coolant escapes, then tighten. This removes trapped air pockets for optimal circulation. - Reinstall Radiator Cap
Replace the radiator cap, ensuring it locks past any safety marks. Wipe down any spills or drips with a rag. - Check for Leaks and Recheck Levels
Start the bike and let it idle for several minutes. After it cools, check the coolant level again and top off if needed. Inspect below for any signs of leaks, especially around the drain bolt and radiator cap.
Model-Specific Tips for the 2014 Husqvarna FC250
- The FC250 uses a high-compression, DOHC 4-stroke engine borrowed from KTM, making coolant changes virtually identical between brands.
- Always inspect both radiators for clogging or debris. FC250s are known for efficient but tightly packed radiators–a gentle rinse can help cooling efficiency.
- Due to the lightweight magnesium engine cases, always use a torque wrench to avoid stripping threads when reinstalling bolts.
- If coolant continuously drops or leaks after a change, the water pump seal may need inspection—a known maintenance point for these models.
