Maintaining the cooling system of your 2016 Husqvarna FE350HQ is essential for optimal engine performance and longevity, especially on tough off-road trails. This exclusive MotoSport step-by-step guide will help you flush and change the coolant on your FE350HQ, including unique tips specific to this model.
Why Change Your Coolant?
Over time, coolant breaks down – losing its ability to keep your engine at the correct temperature and protect vital components from corrosion. For the FE350HQ, this is especially important due to its high-performance, competition-ready nature. Routine coolant changes help prevent overheating and ensure reliable riding, whether you’re crushing dunes or navigating technical single track.
What You’ll Need
- Fresh motorcycle-specific coolant (check your owner’s manual for recommended type; many riders opt for a high-performance coolant)
- Distilled water (for flushing, if needed – do not use tap water)
- Sockets and wrenches (typically 8mm or 10mm for the drain bolt)
- Drain pan and rags
- Funnel
- Appropriate bodywork removal tools (Allen wrenches, etc.)
- Latex or nitrile gloves
Step-by-Step Coolant Change Procedure
- Let the bike cool down completely. Hot coolant is dangerous – begin only when the engine and radiators are safe to touch.
- Remove the radiator cap. This releases system pressure and allows coolant to drain smoothly. The radiator cap is located at the top of the left radiator.
-
Locate and remove the drain bolt. On the FE350HQ, the coolant drain bolt is found at the lowest point of the water pump on the right side of the engine. Use the appropriate socket to loosen and remove it.
Place the drain pan directly underneath to catch all old coolant. - Drain the coolant completely. Tilt the bike slightly from side to side to ensure full drainage from both radiators.
-
(Optional) Flush the system. If your coolant was neglected or contaminated, flush the radiators by reinstalling the drain bolt, filling with distilled water, running the engine briefly, and draining again.
Avoid chemical flushes – distilled water is safest for these lightweight alloy radiators. - Secure the drain bolt. Clean the area and refit the drain bolt. Consider replacing the sealing washer for a leak-free seal.
- Fill with new coolant. Use a funnel and pour slowly into the filler neck until the coolant reaches the top. Squeezing the hoses and gently rocking the bike side-to-side helps release trapped air pockets.
-
Burp the system. Leave the radiator cap off. Start the engine and let it idle for several minutes. Blip the throttle and rock the bike to ensure all air escapes. Re-check the coolant level, top off as needed, then reinstall the radiator cap.
Fill the overflow reservoir to the upper fill line if your model features one. - Check for leaks. Run the engine and inspect all fittings for leaks. Wipe up spills and dispose of used coolant responsibly.
FE350HQ-Specific Notes for Owners
- High-revving engine and compact radiators make proper coolant levels and air-free operation critical to prevent overheating, especially in slow or technical riding conditions.
- Radiator fan (if equipped): FE350HQ bikes often run hotter than trail-only models. Check fan operation after coolant service.
- Coolant capacity is approximately 1 quart (1 liter). Always cross-check with your owner’s manual.
- Avoid mixing coolant types. Always completely flush the system if you are switching brands or color of coolant (e.g., from red to blue).
After Your Coolant Change
- Re-check coolant level after your first ride, once the engine has cooled. Top off as needed.
- Address overheating quickly. If you notice persistent overheating, double-check for trapped air, leaks, or worn radiator cap/seals.
Regular coolant service helps keep your 2016 Husqvarna FE350HQ running cool and prevents costly engine damage – crucial for performance, safety, and longevity.
