How to Change the Coolant in a 2025 Husqvarna FE350S
Shop parts for a 2025 Husqvarna FE350S Dirt Bike.
Routine coolant changes are vital for keeping your 2025 Husqvarna FE350S running at peak temperature and preventing overheating, especially given the model's high-performance, lightweight engine and advanced coolant routing system designed for consistent flow and reduced pressure†.
What Makes the 2025 FE350S Cooling System Unique?
- Large center tube channels coolant through the frame to keep pressure balanced and flow reliable, which is especially noticeable under extreme enduro conditions†.
- Internal thermostat for fine-tuned operating temperature†.
- Engine centralization design: The layout ensures not just performance but easy access for routine fluid maintenance•.
What You'll Need
- Recommended coolant (see your owner's manual or consult a MotoSport expert for the correct spec)
- Basic hand tools (socket set, pliers)
- Catch pan
- Distilled water (for optional flush)
- Rags for spills
Step-by-Step Coolant Change Procedure
- Prep the Bike: Make sure the engine is completely cool before starting. Remove the right radiator shroud for better access.
- Release Pressure: Slowly open the radiator cap to relieve any residual pressure in the system.
- Drain the Coolant:
- Locate the engine coolant drain bolt, typically found at the lowest point on the water pump cover (right side of motor).
- Place a catch pan beneath, then remove the bolt and let the coolant fully drain from both radiators and the engine.
- Flush (Optional but Recommended):
- Reinstall the drain bolt briefly and fill the system with distilled water. Start the engine and let it run for about a minute to circulate and flush residual coolant.
- Let cool, then repeat the draining process.
- Refill with New Coolant:
- Reinstall the drain bolt (torque to spec if possible).
- Fill the radiator with fresh coolant, allowing it to settle and topping off as needed.
- Some FE350S models may require burping the cooling system. To do this, gently rock the bike and squeeze the radiator hoses to expel any trapped air, topping off the fluid as air escapes.
- Check for Leaks – Monitor Level:
- Run the engine until the fan activates, allowing coolant to fully circulate.
- Shut off, let cool, check for leaks at the drain bolt and hose connections, and recheck coolant level. Top off as needed.
- Reassemble and Ride: Reinstall radiator shroud and all removed parts. Dispose of old coolant responsibly.
Noteworthy Tips for 2025 Owners
- The 2025 FE350S uses an advanced frame-integrated coolant routing, which means even filling and burping are more predictable and consistent compared to earlier models† •.
- Factory thermostat ensures fast warmup and optimal running temperature. Always monitor your levels after servicing, especially after the first heat cycle.
- If you ride aggressively or in hot climates, consider a high-performance coolant designed for extreme off-road use.
