Routine coolant changes are crucial for keeping your 2017 Husqvarna TC250 running cool in any conditions. The procedure is straightforward, but there are a few unique notes about this model to keep in mind. Below you will find a detailed, MotoSport-exclusive guide for changing your coolant safely and efficiently.
What You Need
- Fresh coolant suitable for aluminum radiators (refer to owner's manual for specific recommendations)
- Funnel
- Socket set (8mm works for most TC250 drain screws)
- Flat work surface or stand to keep the motorcycle level
- Drain pan or suitable container
- Clean rags
- Gloves and safety glasses
Step-by-Step Instructions
-
Ensure the Bike is Cool & Stable.
Let the engine cool completely. Place the bike upright on a level surface or use a suitable stand to provide access and ensure a full drain. Never attempt to open the cooling system when the engine is hot, as pressure can cause severe burns.
-
Remove the Radiator Cap.
Twist off the radiator cap slowly to release any residual pressure. This step is best done with a cold engine to prevent sudden coolant spray.
-
Locate & Remove the Drain Plug.
The 2017 TC250 features a drain screw located on the water pump cover at the lower right side of the engine. Carefully position the drain pan directly beneath this area.
Use your socket (8mm) to loosen the plug and allow the old coolant to fully drain out. While draining, inspect the removed coolant for contamination or metal particles, as these can indicate potential engine problems. -
Flush the Cooling System (Optional But Recommended).
If the old coolant was discolored, containments are visible, or it's been over two years since the last flush, pour a small amount of clean distilled water through the radiator to rinse out the system. Drain this rinse water completely before proceeding. This is especially helpful on a TC250 as race conditions or mineral-rich water can lead to faster buildup.
-
Reinstall the Drain Plug.
Inspect the plug's sealing washer for damage, and replace if necessary. Tighten the drain screw snugly to the manufacturer's torque spec (do not overtighten), ensuring a leak-free seal.
-
Add New Coolant.
With the drain plug secure, slowly pour your new coolant into the radiator until it's visible just below the filler neck. Lightly rock the bike or gently squeeze the radiator hoses to help release trapped air bubbles.
-
Bleed Air From the System.
The TC250's cooling circuits sometimes trap air, leading to hot spots. Start the engine and let it idle briefly (with the cap off) until the coolant level stabilizes—do not overfill. As bubbles escape, top off the coolant as needed. Once satisfied, reinstall the radiator cap securely.
-
Inspect for Leaks & Recheck Level.
Wipe down any spilled coolant, check the hoses and plug for leakage, and ensure all clamps are secure. After the first ride, let the bike cool fully, then recheck coolant level and top off if needed.
Special Notes for the 2017 Husqvarna TC250 Owner
- This model uses high-performance radiators with lightweight design for motocross, which are more susceptible to damage from debris and tip-overs. Inspect radiators for dings or leaks with each service.
- Never use plain tap water in your TC250; use only distilled water or pre-mixed coolant designed for aluminum engine parts to prevent corrosion or mineral buildup.
- 2017 TC250s are prone to radiator vibration due to aggressive off-road use. Double-check hose clamps and mounting points for tightness, and replace worn rubber isolators to reduce future leaks.
Regular coolant changes ensure your 2017 Husqvarna TC250 stays ready for any ride–from track days to trails–with optimal cooling performance. For all your maintenance needs and genuine parts, MotoSport has you covered every step of the way.
