Shop parts for a 2022 Husqvarna TC125 Dirt Bike.
Routine coolant changes are vital to keeping your 2022 Husqvarna TC125 running reliably, especially given its high-revving two-stroke design. Properly refreshed coolant maintains performance, protects against overheating, and extends engine life. Follow this proprietary MotoSport guide for best results and model-specific tips.
Essential Tools & Supplies
- Fresh coolant – OEM-recommended or premium motorcycle coolant
- Drain pan
- 8mm or 10mm socket/wrench (for drain bolt)
- Flathead screwdriver (if needed for plastics)
- Clean rag or towel
- Safety gloves
Prep Your Workspace
- Work on a cool engine to avoid burns.
- Set the TC125 on a stable stand, keeping it upright for even draining and filling.
Step-By-Step Instructions
- Remove seat and left radiator shroud if these restrict access to the radiator cap.
- Locate the radiator cap at the top of the left radiator. Slowly remove the cap to relieve pressure.
-
Locate the coolant drain bolt or hose on the bottom side of the engine's water pump cover (left side of the engine). Place your pan underneath.
Note: Some coolant may also drain by removing the lower radiator hose. Use the appropriate method for your comfort. - Remove the drain bolt (or lower hose). Allow old coolant to drain fully. Tilt the bike gently to help empty both radiators.
- Inspect the coolant for debris or oil. Any sign of contamination may suggest further servicing is needed.
- Reinstall the drain bolt (or hose) with a new washer if required – torque to manufacturer specs.
-
Fill the radiators slowly with new coolant via the cap opening until level.
Model tip: The 2022 TC125 has cylinder head bleeder screws. After filling, briefly loosen the bleeder screw located atop the cylinder head to evacuate trapped air, then re-tighten once fluid flows out freely. - Top off coolant if needed. Replace the radiator cap securely.
- Wipe down any spillage, reinstall all removed plastics and the seat.
- Start and idle the bike for a few minutes. Check for leaks and verify the coolant level after cooling down, topping off if necessary.
Model-Specific Notes for the 2022 TC125
- Bleeder screw: This feature simplifies air removal from coolant lines, crucial for preventing engine hot spots.
- Coolant type: Always use motorcycle-specific, silicate-free coolant to prevent water pump and radiator corrosion. Avoid automotive green antifreeze or tap water alone.
- Radiator protection: The TC125's radiators are exposed and lightweight. After refilling, inspect guards and hoses for any damage.
- Regular checks: Two-strokes like the TC125 run especially hot under hard use. Monitor coolant level after every few rides, especially in racing or muddy conditions.
When to Change More Frequently
- After overheating incidents
- Following muddy or extreme riding
- Annually as preventive maintenance
Keeping your 2022 TC125's cooling system clean and fresh is one of the best ways to protect your investment and maximize your track time. For all your bike's maintenance needs and model-specific parts, MotoSport supports every ride.
