Shop parts for a 2024 Husqvarna TC65 Dirt Bike.
Keeping your 2024 Husqvarna TC65 in peak riding condition means regularly servicing the cooling system. Fresh coolant maintains optimal engine temperatures, protects against corrosion, and ensures long-term performance. Below, you will find the MotoSport step-by-step guide designed specifically for the latest TC65–backed by official specs and proprietary experience working with this popular mini-motocrosser.
What Makes the 2024 TC65 Unique?
This year–s TC65 features a compact, high-performance 2-stroke engine, equipped with race-derived radiators and a precisely designed cooling circuit. For 2024, the system capacity is approximately 0.55 liters (0.58 qt.), and the coolant path is routed to maximize surface area and heat dissipation. The plastic radiator shrouds help direct airflow efficiently, but require careful reinstallation to maintain their function.
What You Will Need
- Fresh engine coolant compatible with aluminum radiators
- Socket set or T-handle wrenches
- Drain pan
- Funnel
- Soft cloths or paper towels
- Protective gloves
Step-By-Step: Changing the Coolant
-
Preparation:
- Ensure the engine is cool before starting; never open the radiator cap on a hot bike.
- Place the bike on a stable stand and remove the seat and any plastic shroud panels needed for full access to the radiators and cap.
-
Drain Old Coolant:
- Locate the radiator cap and loosen it to relieve pressure–do not fully remove yet.
- Find the coolant drain bolt or the lowest hose connection at the water pump. Position the drain pan underneath.
- Remove the drain bolt or hose and allow coolant to fully evacuate. Tilt the bike slightly if necessary to drain both radiators.
-
Flush (Optional, but Recommended):
- If your old coolant was severely discolored or if you are switching coolant types, flush the cooling system with distilled water. Reinstall the drain bolt/hose snugly before proceeding.
-
Refill with New Coolant:
- Verify that all connections are secured and reinstall the drain bolt (torque to specification if provided in your owner‘s manual).
- Using a clean funnel, pour fresh coolant into the radiator filler neck until it reaches the top.
- Gently rock the bike side-to-side, then top up if necessary to ensure all air pockets are released.
- Install the radiator cap securely.
-
Final Steps:
- Reinstall shroud panels and seat.
- Start the engine and idle for a few minutes, watching for leaks.
- Let the bike cool and re-check the coolant level, topping up if needed.
Important Model-Specific Tips
- Use only coolants compatible with magnesium and aluminum–avoid silicate-based products.
- 2024 TC65 cooling system holds around 0.55 liters (0.58 qt.). Overfilling may lead to excess pressure and leakage.
- Genuine Husqvarna radiator hoses are pre-formed; improper reseating after service can cause pinching or leaks.
- Tighten bolts to the recommended torque. Over-tightening can strip threads in the lightweight engine cases.
- Dispose of old coolant properly–never pour down storm drains or onto soil.
Maintaining Peak Performance
The TC65 is engineered for young racers and demands meticulous care for repeated heat cycles. Cooling system service at least once per season extends water pump seal life and protects against overheating during hard motos. After changing coolant, keep an eye out for any seepage around pump, hoses, or radiator cores during first few rides.
