Maintaining the cooling system on your 2016 Husqvarna FE501HQ is essential for optimal engine performance. Regular coolant changes help prevent corrosion, overheating, and costly engine repairs. This step-by-step guide covers the procedure specific to the FE501HQ and offers model-specific notes every owner should know before beginning.
What You Need
- Fresh coolant (ensure it's compatible with aluminum radiators; premixed or mix 50-50 with distilled water)
- Drain pan
- Socket set
- Torque wrench
- Shop rags
- Protective gloves and eyewear
- New sealing washer for drain bolt (recommended for a secure seal)
Preparation
- Allow the engine to cool completely before starting service to avoid burns and pressurized coolant spray.
- Set the motorcycle upright and level, preferably on a stand, to ensure proper drainage and refilling.
Step-by-Step Coolant Change
- Access the Radiator: Remove the seat and shrouds if necessary for easier access to the radiator cap and drain bolt.
- Remove the Radiator Cap: Unscrew the radiator cap to relieve pressure from the cooling system.
- Drain the Old Coolant: Position the drain pan below the water pump or designated coolant drain bolt (usually located at the bottom side of the right engine case). Remove the bolt and allow old coolant to drain completely.
- Flush (Optional but Recommended): To remove more residue, flush the system with distilled water. Reinstall the drain bolt, fill the radiator with distilled water, run the engine briefly, then drain again.
- Reinstall the Drain Bolt: Replace the sealing washer on the drain bolt. Torque the drain bolt to the manufacturer's specification to ensure a leak-free seal.
- Refill the System: Fill the radiator slowly with fresh coolant to the top of the filler neck. Ensure you use 1.2L (1,200ml) – the recommended capacity for the FE501HQ cooling system.
- Burp the Radiator: To release trapped air, leave the radiator cap off, start the engine, and gently rock the bike side to side. Watch for bubbles; once they stop, top off coolant if needed.
- Check for Leaks and Finalize: Shut off the engine, recheck coolant level, top off the overflow reservoir to the indicated line, and reinstall all removed parts.
Finish Up
- Properly recycle old coolant at a hazardous waste facility.
- After your first ride, recheck the coolant level and top off if necessary.
Husqvarna FE501HQ Owner Notes
- The FE501HQ model holds approximately 1.2L of coolant. Overfilling can cause overflow while running, so measure carefully.
- Only use coolant formulated for use in motorcycles with aluminum radiators. Avoid automotive coolants containing silicates, as they can cause internal damage.
- Check hoses and clamps for wear or damage during the process. Replace with OEM or MotoSport-approved parts as needed for optimal reliability.
- If you ride in extreme conditions (high heat, heavy loads), inspect your coolant condition more frequently, as performance riding can stress the system.
Staying on top of coolant maintenance means more confidence every ride – and less risk of getting stranded. Follow the steps above for a hassle-free service, and trust MotoSport for everything you need to keep your 2016 Husqvarna FE501HQ running at its best.
