Keeping your 2017 Husqvarna FE350HQ performing optimally requires regular coolant changes. This guide provides a step-by-step process tailored for your FE350HQ, along with model-specific tips every owner should know.

Tools and Supplies Needed
- Fresh motorcycle engine coolant compatible with aluminum radiators (many prefer performance brands like Engine Ice, but choose according to your climate and needs)
- Socket set or correct spanner for radiator drain bolt
- Phillips screwdriver (if radiator shrouds need removal)
- Shop rags or paper towels
- Catch pan for old coolant
- Distilled water (for flushing system, optional but recommended)
- Funnel
- Protective gloves
2017 FE350HQ-Specific Notes
- The FE350HQ shares many design features with KTM models of the era, including twin radiators and a side drain bolt for easy coolant removal.
- This model's high-compression, four-stroke engine requires especially clean and effective coolant for heat management.
- The cooling system is sensitive to air pocketsensure thorough bleeding when refilling to avoid hot spots.
- If you ride in hot climates or use your bike hard, consider upgrading to a higher-capacity coolant reservoir (a popular mod that helps prevent overheating, especially on dual sport and trail conversions).
Step-by-Step Coolant Change
- Let the Engine Cool: Ensure your FE350HQ is completely cool before servicing to avoid burns and pressure hazards.
- Remove Radiator Cap: Slowly open the radiator cap (located on the right-side radiator) to release system pressure.
- Access the Drain Bolt: Locate the coolant drain bolt at the bottom of the water pump housingtypically on the right side of the engine, below the clutch cover.
- Drain Old Coolant: Position your catch pan underneath, then remove the drain bolt and allow the coolant to completely drain from the system. For a more thorough flush, lightly rock the bike side to side to help clear both radiators.
- Optional Flush: For best results, re-install the drain bolt and fill the system with distilled water. Run the bike for a brief period (just long enough to circulate), allow it to cool, then drain again.
- Reinstall Drain Bolt: Replace and torque the drain bolt as specified by Husqvarna. Always use a fresh washer if equipped.
- Fill With New Coolant: Using a funnel, pour fresh coolant into the radiator up to the base of the filler neck. On the FE350HQ, the system capacity is just under 1.3 litersdo not overfill.
- Bleed Air from the System: With the front wheel elevated, gently squeeze the radiator hoses to help purge trapped air. Some owners also use the bleed screw on top of the right-hand radiator if equipped. Reinstall the radiator cap after filling.
- Start and Warm Up: Start the engine and let it reach operating temperature, allowing the thermostat to open. Watch for any bubbles or drops in leveltop off coolant if the level drops after cycling.
- Check After Cool Down: Turn off the bike and let it fully cool. Reopen the cap and ensure coolant is still at the proper level, adding more as needed.
- Inspect for Leaks: Verify all seals, the drain bolt, and hose clamps are leak-free before your next ride.
Pro Tips for the 2017 FE350HQ Owner
- If your model is equipped with a fan kit or aftermarket temperature sensor, check these components for debris and function during coolant service.
- Consider installing a coolant overflow reservoir if you ride in extreme conditions. This mitigates boil-over issues and provides extra insurance against overheating.
- Always dispose of old coolant responsibly, as it is toxic to humans and animals.
