Changing the coolant in your 2016 Husqvarna FE250HQ is a straightforward maintenance task vital for optimal engine performance – especially if you ride hard or frequently face hot conditions. This proprietary MotoSport guide will walk you step-by-step through draining the old coolant, flushing the system, and adding fresh coolant, with tips specific to this Husqvarna model.
What Makes the FE250HQ Unique?
The 2016 FE250HQ shares many design cues with its KTM cousins but features Husqvarna-specific radiators and plastics. Its closed-loop cooling system is robust but sensitive to air pockets; properly burping the system is especially important to prevent overheating and fan cycling. This bike is often used in technical, slow-speed environments where cooling performance is crucial, so regular coolant changes are strongly advised.
Tools and Supplies Needed
- 8mm or 10mm socket or wrench (check your specific drain bolt size)
- Catcher pan for old coolant
- Funnel
- New coolant (pre-mixed or mix with distilled water; avoid tap water)
- Optional: Distilled water for system flush
- Cotton rags (for any spills)
- Torque wrench (recommended for reinstalling drain bolt)
- Latex gloves (for protection)
Step-by-Step Procedure
-
Preparation
Ensure the motorcycle is cool to the touch. Secure it upright on a stand or level surface to allow for complete draining. -
Remove the Radiator Cap
Loosen the radiator cap carefully to relieve system pressure before draining. This step is crucial on the FE250HQ to prevent coolant sprays and speed up draining. -
Locate and Remove the Coolant Drain Bolt
The drain bolt is typically found at the lowest point on the water pump housing. Place the catcher pan underneath, remove the bolt, and let the old coolant drain fully. Inspect the drained coolant for debris or oil, which can indicate internal issues. -
Flush the System (Recommended for bikes with unknown service history or dirty coolant)
With the drain bolt still out, pour distilled water into the radiator until it runs clear out of the drain hole – this helps flush out sediment and mineral deposits. Optionally, you can briefly reinstall the bolt and run the engine with distilled water, then repeat the process for a more thorough flush. -
Reinstall the Drain Bolt
Use a clean sealing washer if necessary. Tighten the bolt to manufacturer specifications (do not over-tighten). -
Add New Coolant
Using a funnel, slowly pour fresh coolant into the radiator until it reaches the filler neck. Premixed coolant is easiest, but if you use concentrate, mix with distilled water as recommended (typically 50/50). Do not use tap water as it can cause scaling and reduce cooling system efficiency. -
Burp the Cooling System
Start the engine with the radiator cap off and run it until the thermostat opens (the radiator will feel warm). Blip the throttle and tilt the bike gently side to side to help release air bubbles. Watch for the coolant level to drop, then top off as needed. This step is vital for the FE250HQ since trapped air can cause overheating and frequent cooling fan activation. -
Check and Top Off the Overflow Reservoir
Locate the overflow bottle and fill it to the recommended line. Replace the radiator cap securely after the system is fully burped. -
Inspect for Leaks and Test Ride
Wipe down any spills, run the bike, and check the drain bolt and hoses for leaks. After your next ride, recheck the coolant level and top off if necessary, as residual air may escape after the first heat cycle.
Additional Tips for 2016 FE250HQ Owners
- Change coolant every 40–50 hours of run time or a minimum of once per year under typical use.
- Engine ice or high-performance coolants can improve resistance to boiling and are a smart upgrade for slow or technical trail riders.
- Always dispose of old coolant at a proper recycling facility – it is toxic and harmful to the environment.
- If you notice recurring overheating, check for clogged radiator fins or a malfunctioning radiator fan – both are common on these bikes when ridden in muddy or dusty environments.
Following this guide will keep your 2016 Husqvarna FE250HQ running cool and reliable, regardless of terrain or temperature. Take pride in maintaining your bike the MotoSport way.
