Essential Tools & Supplies
- Correct coolant/antifreeze (make sure it is compatible with aluminum radiators and prepared for your typical riding temperatures).
- Basic hand tools (typically a socket set and screwdriver).
- Drain pan or suitable container.
- Rags or shop towels for cleanup.
- Protective gloves and eye protection.
Step-by-Step Coolant Change Instructions
- Let the Bike Cool Down
Never attempt to open the cooling system when the engine is hot. Always allow the TC50 to cool fully before servicing. - Remove the Seat and Plastics (if necessary)
For easier access, you may want to remove the seat to reach the radiator cap. This can be done simply by hand, thanks to the quick-release design. - Upright the Motorcycle
Position the bike securely and upright on a stand. - Remove the Radiator Cap
Wearing gloves, carefully unscrew and remove the radiator cap to release any pressure in the system. - Place a Drain Pan Under the Water Pump Cover
Locate the coolant drain bolt typically on the lower part of the water pump cover. Place your drain pan directly underneath. - Remove the Drain Bolt and Drain the Coolant
Slowly loosen the drain bolt. Allow the old coolant to drain completely into your pan. Dispose of used coolant properly as it is toxic and harmful to the environment. - Inspect & Clean
Check the condition of the drain bolt washer and water pump cover for any debris or corrosion. Replace the washer if necessary. - Reinstall the Drain Bolt
Refit the drain bolt and tighten to the specified torque. Do not overtighten. - Refill with New Coolant
Pour fresh coolant into the radiator neck until full. Gently rock the bike side to side or squeeze the coolant hoses to help remove any trapped air. - Start the Engine Briefly
With the radiator cap off, start the bike and let it idle for a few moments to circulate coolant and burp out any remaining air bubbles. Watch for the coolant level to drop and add more if needed. - Check the Level & Reinstall the Cap
Once air bubbles stop and the coolant maintains its level, top off if necessary, then securely reinstall the radiator cap. - Reinstall Seat & Plastics
If you removed the seat or any bodywork, reinstall them before riding. - Dispose of Old Coolant Properly
Never pour used coolant down the drain or onto the ground. Take it to a local hazardous waste center or recycling facility.
Pro Tips for TC50 Owners
- Always use a high-quality coolant that is safe for aluminum engines and offers freeze and boil protection within your riding environment.
- If your young rider participates in races or rides in extreme conditions, coolant inspection and change intervals may need to be more frequent than casual trail riding.
- Watch for any leaks or frequent drops in coolant level, which could indicate worn seals or hoses.
- Husqvarna recommends checking other systems like brakes and air filter at regular maintenance intervals to keep your TC50 running at its best.
By following these steps, you ensure your 2025 Husqvarna TC50 stays cool, protected, and ready for every ride giving your young racer the best start in motocross.
