Changing the coolant in your 2015 Husqvarna FE250HQ is an essential part of maintaining peak engine performance and longevity. This guide walks you through the process step-by-step, highlighting special considerations for this model and offering proprietary MotoSport tips.
Why Change Your Coolant?
Coolant helps regulate your bike's temperature, prevents corrosion inside the cooling system, and ensures reliable operation on and off the trail. Old or contaminated coolant loses effectiveness, risking engine overheating or internal corrosion.
Tools & Supplies Needed
- Ready-mixed motorcycle coolant (do not use plain water)
- Drain pan or suitable container
- Rags or shop towels
- Basic hand tools (socket or wrench set, typically 10mm for drain bolt)
- New sealing washer for the drain bolt (recommended)
- Funnel
- Safety gloves and eye protection
Step-by-Step Coolant Change for the FE250HQ
- Preparation
- Ensure the engine is completely cool before starting. Place the bike on a stable, level surface or stand, keeping it upright for accurate draining and filling.
- Remove the Radiator Cap
- Locate the radiator cap above the left radiator. Open it slowly to relieve any residual pressure.
- Drain the Old Coolant
- Position the drain pan under the water pump (left side of the engine case).
- Use a 10mm wrench to remove the drain bolt at the base of the water pump cover. Allow all coolant to drain fully. Inspect and replace the sealing washer if worn.
- Flush the System (Optional but Recommended)
- For neglected or dirty systems, flush with distilled water. Pour distilled water into the system, reinstall the drain bolt, briefly run the bike until warm, then repeat the draining process.
- Reinstall the Drain Bolt
- Install the drain bolt with a fresh sealing washer, tightening to 10 Nm (7.4 lbf ft) to prevent leaks.
- Fill with New Coolant
- Slowly pour new, ready-mixed coolant into the radiator using a funnel. Fill until the coolant reaches the top of the radiator's filler neck. Move the bike gently side-to-side and squeeze coolant hoses to expel air pockets.
- Top Off the Expansion/Reservoir Tank
- Fill the tank up to the upper level mark, if equipped.
- Bleed the System
- With the radiator cap off, run the engine at idle for 2–3 minutes. Briefly rev the engine to around 4000–5000 rpm. Shut off and let cool.
- Check coolant levels again, topping off the radiator and reservoir as needed.
- Secure the radiator cap and reservoir cap firmly.
- Cleanup and Inspection
- Check for leaks at hose connections, drain bolt, and caps. Monitor the coolant level after your first ride or two and adjust as needed.
Special Notes for the 2015 Husqvarna FE250HQ
- This model features a compact, high-performance four-stroke engine with minimal coolant volume, making air bleed especially important. Double-check for trapped air to avoid hotspots.
- Husqvarna recommends factory-approved coolants to protect magnesium and aluminum components in the cooling circuit. Using generic car coolant may cause corrosion; always verify compatibility.
- The FE250HQ's radiator and water pump access is excellent, but always be gentle with plastic radiator shrouds and connectors to avoid cracking or leaks during maintenance.
- Replace the coolant every two years or after extended high-heat riding for optimal engine protection.
Final Tips
- Dispose of old coolant responsibly—it is toxic to people & pets.
- Inspect hoses for age cracks or swelling—replace as needed.
- Coolant leaks are often visible as colored deposits near seals and joints. Address immediately to avoid engine damage.
Regular coolant changes are a simple way to keep your Husqvarna FE250HQ running strong wherever you ride.
