Shop parts for a 2016 Husqvarna TC85 Dirt Bike.
Changing the coolant in your 2016 Husqvarna TC85 is an essential part of regular maintenance. Coolant plays a critical role in keeping your engine temperatures consistent and preventing overheating, especially during hard riding. Follow this robust MotoSport-exclusive guide to ensure your TC85's cooling system is fresh, clean, and protecting your investment.
What You Need
- Fresh, model-appropriate coolant (ready-to-use or mix with distilled water if concentrate)
- Drain pan
- Ratchet or wrench set
- Funnel
- Clean rags
- Safety glasses and gloves (recommended)
Step-by-Step Coolant Change Process
- Preparation
- Ensure the engine is cool before starting – never open the radiator cap or drain coolant when hot to avoid burns.
- Place your dirt bike upright on a stable stand.
- Access the Radiator Cap
- Remove the seat and left shroud panel if needed for better access to the radiator cap.
- Slowly loosen the radiator cap to release system pressure.
- Drain Old Coolant
- Locate the coolant drain bolt at the bottom of the water pump or lower-side engine case. Place a drain pan underneath.
- Remove the drain bolt and allow coolant to fully drain.
- Some TC85 models have dual radiators—ensure both sides empty by gently leaning the bike side-to-side.
- Check and replace the crush washer on the drain bolt if necessary.
- Flush the System (Recommended)
- Reinstall the drain bolt (torque to spec: 10 Nm/7.4 ft-lb is common for similar models; confirm in your manual).
- Fill the radiators with distilled water; reinstall the cap. Start and idle the bike for 1-2 minutes (not long).
- Let it cool, then repeat the drainage process to flush contaminants.
- Refill with Fresh Coolant
- Ensure the drain bolt is snug and the bike is level.
- Using a funnel, pour in fresh coolant until it rises just above the radiator core fins (approx. 0.95 L/1 US quart is typical for the TC85—do not overfill).
- It is important to use distilled water if mixing from concentrate to avoid mineral scaling.
- Bleed Air from the System
- With the radiator cap off, start the engine and let it idle for a few minutes.
- Rock the bike gently side to side and blip the throttle to help trapped air escape (burp the system).
- Certain year models feature a small bleed screw at the top of the cylinder head—crack this briefly to allow any remaining air to escape, then retighten securely.
- Recheck coolant level and top off as needed so it sits just over the cores.
- Finishing Touches
- Reinstall the radiator cap and bodywork.
- Start your TC85 and monitor for leaks and proper operation. After the first ride, double-check coolant level again.
- Dispose of used coolant responsibly at a local recycling center.
2016 Husqvarna TC85 Owner Notes
- Coolant Capacity: Refer to your owner manual for exact volume—overfilling can affect pressure and efficiency.
- The TC85's high-revving 2-stroke engine is sensitive to coolant quality—always use a coolant rated for aluminum engines and compatible with high-performance bikes.
- Check for sediment or rust during draining; these may indicate the need for more frequent maintenance or inspection of the radiator and hoses.
- Consider periodic inspections of the radiator cap and hoses as the model ages—cracks or stiffness can cause leaks or pressure losses.
Changing your coolant regularly keeps your 2016 Husqvarna TC85 running cool and protected, letting you ride harder and longer. For all genuine and performance parts to keep your TC85 in top shape, MotoSport has you covered.
