Maintaining your 2018 Husqvarna TC250 means ensuring your cooling system is always in top shape. Changing the coolant is a core maintenance task that protects your engine from overheating and corrosion. Below you will find our proprietary step-by-step guide specific to the TC250, including important safety tips and model-specific notes that every owner should know.
Why Change the Coolant?
- Preserves engine life – Fresh coolant inhibits corrosion and manages engine heat.
- Enhances performance – The correct coolant keeps your 2-stroke engine running at optimal temperature.
- Prevents overheating – Old coolant can lose its effectiveness, especially after a season of hard riding.
What You Need
- Replacement coolant compatible with aluminum radiators
- 8mm socket or wrench
- Suitable drain pan
- Funnel
- Clean rag
- Protective gloves
Step-by-Step Coolant Change
-
Ensure the engine is cool:
Never attempt this task with a hot engine or radiator to avoid burns. -
Stand the bike upright:
Position the motorcycle upright and level on a stand. Place a suitable container under the right side of the engine, below the water pump cover. -
Remove the radiator cap:
Take off the radiator cap to release pressure and allow the system to drain fully. -
Drain the coolant:
Locate the 8mm drain bolt on the water pump cover (right side of engine). Use your wrench or socket to loosen and remove it. Allow all old coolant to drain completely into your catch pan.
Note: On the 2018 TC250, it's crucial to ensure you get all coolant out, as residue may linger in engine cavities. Tilting the bike slightly from side to side can help evacuate stubborn pockets. -
Flush (optional but recommended):
Pour distilled water into the radiator, refit the drain bolt, and gently tilt the bike to circulate. Remove the drain bolt again and allow the water to drain until clear. This will remove any sediment or contaminants. -
Reinstall the drain bolt:
Fit the bolt securely but do not overtighten. Clean any coolant spills from the engine area. -
Refill with fresh coolant:
Using a funnel, slowly fill the radiator with the recommended coolant, leaving an air gap at the top as specified in your owner’s manual. For the TC250, ensure the coolant is filled up to the inner neck of the radiator.
Do not overfill, as this can cause spillage during operation. -
Air bleed and check level:
Gently rock the bike or squeeze the hoses to release any trapped air bubbles. Reinstall the radiator cap. -
Run and recheck:
Start the engine and let it idle briefly, then shut it off and allow it to cool. Remove the radiator cap and check the level again, topping off if necessary. -
Dispose of coolant responsibly:
Used coolant is hazardous. Always dispose of it according to local environmental regulations.
Model-Specific Notes for 2018 TC250 Owners
- Radiator construction: The TC250’s lightweight aluminum radiators require a silicate-free, anti-corrosion coolant designed for modern motocross bikes.
- Coolant intervals: For race or hard off-road use, change coolant at least once per season, or more often in extreme conditions.
- Inspection tip: Use each coolant service as an opportunity to inspect hoses and radiator fins for leaks, wear, or clogs, which are common on this model after muddy rides.
Quick Pro Tips
- Always check the coolant level before every ride for optimal cooling.
- If the coolant appears murky or rusty, flush the system immediately.
- Only use coolants specifically labeled for use with magnesium components if your TC250 features magnesium engine parts.
