Important Note About the 2015 Husqvarna TC250
This model utilizes a high-performance two-stroke engine with a pressurized aluminum radiator system. Always use a high-quality, silicate-free coolant designed for dirt bikes to prevent corrosion and ensure maximum cooling under extreme use.
Step-by-Step Coolant Change Guide
- Ensure Engine is Cool
Before starting, let your TC250 sit until the engine and radiators are completely cool. Attempting to remove the radiator cap while the bike is hot could cause burns from pressurized steam and hot coolant. - Upright the Bike
Position your bike securely on a stand so it is completely upright. This ensures even draining and filling1. - Remove the Radiator Cap
Carefully unscrew and remove the radiator cap from the left radiator. Place it somewhere clean. - Locate and Remove the Drain Screw
Find the coolant drain screw on the water pump cover (typically on the right side of the engine)4. Place your catch pan beneath the pump. Remove the screw and allow all coolant to drain. If the system is clogged, gently lean the bike to the side to help empty both radiators. - Flush the System (Optional but Recommended)
With the drain screw removed, slowly pour some distilled water into the open radiator neck. Let it drain through to flush out remaining old coolant or debris. Replace the drain screw and torque it to spec. - Refill with New Coolant
Insert a clean funnel into the radiator neck. Pour in fresh coolant until the level reaches the base of the neck. Gently tap the radiator hoses or carefully squeeze them to help dislodge any trapped air bubbles. - Reinstall the Radiator Cap
Ensure the coolant level is correct. Reinstall the radiator cap securely. - Run the Engine and Check Levels
Start the bike and let it idle for several minutes with the cap on to heat-cycle the coolant and release trapped air1. Shut off, let the engine cool, then check the coolant level again. Add coolant if needed. Repeat until the level stabilizes after a complete cool-down.
Additional Tips for Your TC250
- Check for detectable leaks from hoses, clamps, or the water pump after your first ride.
- If you ride in extreme environments, consider upgrading hoses or the radiator cap to manage increased pressure.
- Flush the coolant system at least once per season or after any high-heat event like a race or long ride.
