- Basic hand tools (mainly socket set and screwdrivers)
- Sufficient clean water for system flushing (distilled recommended)
- Protective gloves and rags
Key Details on the 2009 Husqvarna TC250
- This model uses a dual-radiator, high-flow cooling system engineered for motocross demands. Always use coolant with anti-corrosive properties; never run pure water long-term for this bike.
- Radiators are mounted high and are prone to vibration, so double-check all clamps and hoses for security during maintenance.
- OEM specification recommends keeping the bike upright while draining and filling the system for proper coolant distribution.
Step-by-Step Coolant Change for the TC250
- Let the engine cool completely. Coolant is under pressure when hot and can cause burns if opened too soon.
- Set the bike upright using a stand. Remove any plastic shrouds that block the radiator cap or water pump area.
- Remove the radiator cap. Slowly crack it open to relieve any residual pressure.
- Place your drain pan under the water pump cover.
- The 2009 TC250 has a dedicated drain bolt on the water pump cover on the right side. Use the appropriate socket to loosen this bolt and allow coolant to fully drain.
- Flush the system (recommended).
- Reinstall the drain bolt, then fill the radiators with distilled water. Run the engine for 1–2 minutes (do not let it get hot), then drain again. Repeat if coolant was especially dirty or contaminated.
- Inspect hoses and radiator fins.
- Check for leaks, soft hoses, or bent fins. If you find damage, replace as needed. Secure all clamps snugly, but do not overtighten plastic or aluminum components.
- Refill with new coolant.
- Pour fresh coolant into the radiator neck until it reaches the base of the filler. Don't forget to top off both radiators if your bike has dual caps.
- Check for air pockets.
- Gently rock the bike side to side and tap radiator hoses to help bubbles escape. On first startup, leave the radiator cap off and let the engine idle until the thermostat opens (if equipped). Top off coolant if the level drops.
- Once you are sure air is purged, secure the radiator cap.
- Check coolant level after test ride.
- After the engine fully cools down, recheck the level in the radiator and the overflow, topping off if needed. Monitoring levels is especially important following a complete flush.
Important Notes for TC250 Owners
- Avoid mixing different coolant types – always flush thoroughly if changing brands or formulas.
- This model can suffer leaks from radiator seams or vibration damage; inspect after tough rides or tip-overs.
- Fastener torque is critical for aluminum water pump covers – overtightening can crack the housing.
Proper cooling system maintenance extends engine life, prevents overheating failures, and helps you get maximum performance from your 2009 Husqvarna TC250. Maintain with confidence using genuine parts and fluids available at MotoSport.
