Changing the coolant on your 2017 Husqvarna FC250 is a key part of routine maintenance, ensuring reliable engine cooling, maximum performance, and longevity of vital components. This proprietary MotoSport guide walks you through every step – and highlights model-specific advice FC250 owners will find valuable.
What You Need
- Fresh coolant (preferably a blue G11 type, compatible with OEM specifications)
- Catch pan or container
- 8 mm socket or wrench (to remove drain bolt)
- Funnel
- Torque wrench (optional, but recommended for reinstallation)
- Gloves & rags (for personal protection and cleanup)
Procedure
- Let the Engine Cool Completely
Ensure your FC250 is cool to the touch. Never open the radiator cap on a hot engine – pressurized hot coolant can spray out and cause burns. - Stabilize the Motorcycle
Place the bike upright on a stand or secure surface to ensure the cooling system drains evenly. - Remove the Radiator Cap
Locate the radiator cap on the left side of the bike. Turn it slowly to release any residual pressure, then remove. - Locate and Remove the Drain Bolt
Find the coolant drain bolt on the water pump cover (typically the bolt with a copper sealing washer). - Place your catch pan underneath and use the 8 mm socket or wrench to remove the drain bolt. Allow coolant to fully drain.
Note: The FC250 uses roughly 1.2 liters of coolant. Keep an eye out for old coolant color (Husqvarna originally fills with blue type coolant). - If desired, flush the system with distilled water for a cleaner result. Replace the drain bolt and copper sealing washer, torquing as specified in your owner's manual.
- Refill with Coolant
Use a funnel to slowly pour new coolant into the radiator until the level is at the bottom of the fill neck. Do not overfill. - Replace the radiator cap securely.
- Bleed the Cooling System
Start the engine and let it run for a few minutes. Cycle the throttle a few times with the bike upright. Watch for air bubbles escaping from the radiator neck (if you left the cap off briefly), or gently rock the bike side to side to help release trapped air. - After warm-up, shut off the engine and let it cool. Recheck and top off coolant if the level has dropped. Repeat heat/cool cycle if necessary until the level remains stable after cooling.
- Check the coolant reservoir level (if equipped) and refill to the indicated line.
Model-Specific Notes for the 2017 FC250
- Coolant Type: The 2017 FC250 originally uses a blue G11-type antifreeze. Avoid mixing with other colors; use the same type for top-offs and changes, or flush fully if switching to another type.
- Cooling System Design: Husqvarna's closed cooling system includes an expansion tank. Make sure to check this tank after the first heat/cool cycle for air pockets – top off if necessary.
- Routine Inspection: Inspect radiator hoses and water pump area for leaks or cracks, as the FC250's high-revving nature can wear these parts.
- Always use a new copper sealing washer on the drain bolt to avoid leaks after reinstallation.
Final Checks
- Confirm the radiator is filled to the base of the neck and the reservoir (if present) is at the correct level after the engine is cool.
- Address persistent coolant loss or bubbles after several cycles, as this may indicate a more serious issue requiring professional inspection.
Keep your 2017 Husqvarna FC250 performing at its best – regular coolant changes are quick, straightforward, and essential maintenance. For all your parts and maintenance needs, MotoSport has you covered above.
