Shop parts for a 2025 Husqvarna TC65 Dirt Bike.
The 2025 Husqvarna TC65 is engineered for ambitious young riders, boasting a liquid-cooled 65cc engine, advanced suspension, and a lightweight, agile frame. Ensuring correct coolant levels is vital for both performance and long engine life, especially given the bike's high-revving nature and focus on reliability for up-and-coming racers. Proper coolant maintenance helps avoid overheating, corrosion, and costly repairs – and it's a quick job you can tackle in your own garage.
Why Coolant Changes Matter on the 2025 TC65
- The TC65's compact engine generates significant heat, requiring efficient cooling.
- Fresh coolant maintains optimal engine temperature and prevents corrosion inside the radiator and water passages.
- Sticking with OEM-recommended coolants ensures compatibility and maximum protection for magnesium and aluminum components.
Tools & Supplies Needed
- OEM-compatible coolant (as recommended in your owner's manual)
- 8mm socket or T-handle
- Drain pan
- Funnel
- Rags for cleanup
- Nitrile gloves (optional but recommended)
Step-by-Step: Changing the Coolant
- Prepare the Bike
Ensure the TC65 is completely cool – never open the radiator cap on a hot engine. Position the bike upright on a stand or level ground for safety and stability. - Access the Radiator
Remove the radiator shrouds if needed for easier access to the radiator cap. Carefully unscrew and remove the cap to release any built-up system pressure. - Drain the Old Coolant
Place a drain pan under the right side of the engine, where the water pump is located. Use the 8mm socket to remove the coolant drain bolt found at the base of the water pump cover.
Allow the old coolant to drain completely. Slightly lean the bike from side to side to ensure all coolant is out.
Inspect the drained fluid; if it appears rusty or milky, you may need further servicing or inspection. - Reinstall the Drain Bolt
Once all coolant has drained, replace and tighten the drain bolt securely. Clean off any spilled coolant from the engine and cases. - Refill the Radiator
Place a funnel in the filler neck and slowly add fresh coolant, filling the radiator until the fluid reaches the bottom of the filler neck as specified for the TC65. - Bleed Air From the System
Rock the bike gently side to side and squeeze the radiator hoses to help release any trapped air bubbles. Top off the coolant if level drops after air escapes. - Replace the Radiator Cap
Reinstall the cap, ensuring it is tight and secure. Wipe away any excess coolant with your rag. - Check for Leaks & Test
Start the engine and let it idle for a few minutes, monitoring for any leaks at the drain bolt or around the radiator. Once the bike has cooled, double-check the coolant level and top off if needed.
2025 TC65 Owner Tips
- Check coolant level: Inspect before every ride, especially during hot weather or after heavy use.
- Only use recommended coolants: Mixing different types can damage your system or reduce effectiveness.
- Inspect hoses & clamps: Look for cracks, swelling, or leaks, and replace as needed to avoid mid-race breakdowns.
- The 2025 TC65 features easily accessible cooling system components, simplifying routine service – a thoughtful update for time-pressed parents and racers.
