Maintaining the cooling system on your 2020 Husqvarna FC250 is essential for race-ready performance and engine longevity. Below is MotoSport's exclusive step-by-step guide to changing the coolant in your FC250, with specific notes about what FC models require.
What You Need
- Pre-mixed motorcycle coolant (consult your owner's manual Husqvarna recommends a phosphate-free anti-freeze)
- 10 mm socket or wrench
- New sealing washer for the drain bolt (optional but recommended)
- Funnel
- Catch pan
- Safety gear: gloves, eyewear
- Torque wrench capable of measuring 10 Nm (7.4 lbf ft)
Important. Safety & Handling Notes for FC250 Owners
- Only perform this maintenance with the engine completely cold.
- Always keep coolant away from skin, eyes, and clothing. If any contact occurs, wash thoroughly with water and consult a physician if needed. Coolant is toxic and harmful if swallowed.
- Dispose of all used coolant responsibly at a chemical waste facility or auto parts store.
Step-By-Step Coolant Change Process
- Upright the FC250
Secure the bike on a stand, keeping it vertical for a clean drain. - Remove the Radiator Cap
Locate the radiator cap on the left side. Remove it to relieve any pressure in the system. - Locate the Water Pump Drain Bolt
The coolant drain bolt for the 2020 FC250 is found on the water pump cover (right side of the engine, near the lower radiator hose). It is identifiable by the copper sealing washer.
- Place a catch pan under the drain area. - Remove the Drain Bolt
Using the 10 mm socket, carefully remove the drain bolt.
- Let the coolant flow completely into the pan.
- Inspect the old washer; replace if possible to ensure a leak-free seal. - Reinstall the Drain Bolt
Install the drain bolt with the (ideally new) copper washer. Tighten to 10 Nm (7.4 lbf ft) using a torque wrench as recommended for your FC250. - Fill the Radiator with Coolant
Using a funnel, slowly pour the pre-mixed coolant into the radiator until it reaches the top of the filler neck.
- Your 2020 FC250 holds about 0.95 liters (1 US quart). - Burp the Cooling System
To remove any trapped air (a common cause of overheating), keep the radiator cap off and start the engine.
- Gently rev the throttle and rock the bike side-to-side for several minutes to aid air removal.
- Watch for bubbles escaping and add more coolant as the level drops. - Top Off & Replace Radiator Cap
- Once all bubbles are gone and fluid stays at the filler neck, replace the radiator cap securely.
- Fill the coolant overflow reservoir (if equipped) up to the upper mark. - Check for Leaks & Finalize
- Start the engine once more and let it reach operating temperature.
- Recheck for leaks around the drain bolt and radiator cap.
- After cooling, confirm the coolant level again and top off if needed.
FC250-Specific Tips & Notes
- The FC250 uses a high-performance aluminum radiator — never use tap water as it can cause corrosion and clog fine passages. Only use high-quality distilled water and approved coolant blends.
- Upon changing coolant, it's a great time to inspect the water pump seal and radiator hoses for wear or leaks – common failure points in the KTM/Husqvarna group.
- Always use the correct torque on the drain bolt to avoid stripping threads in the soft aluminum water pump cover.
- Racing or extreme-use riders may benefit from routine coolant changes every race season to maintain peak cooling efficiency.
