Routine maintenance of your Husqvarna TC250 ensures top performance on the track – and changing the coolant is one of the most important tasks for protecting your two-stroke powerhouse from overheating and premature wear. Whether you're prepping for the next race or tackling weekend trails, follow this MotoSport guide for a safe, efficient coolant change made specifically for your 2016 TC250.
What You'll Need:
- Fresh coolant (OEM-recommended or high-performance, non-silicate antifreeze made for aluminum engines)
- Socket wrench or screwdriver (for radiator and water pump covers)
- Catch pan
- Funnel
- Clean rags
- Distilled water (for flushing, optional but recommended)
Step-by-Step Coolant Change Guide
- Preparation
Park your TC250 on a level surface with the engine cool to the touch. Stand the bike upright to ensure the coolant drains completely from the system.
- Remove the Radiator Cap
Slowly remove the radiator cap to relieve pressure in the system. Do this gently – never open a radiator cap when the engine is hot to prevent burns from pressurized steam.
- Drain the Old Coolant
Position a catch pan under the water pump cover. Locate and remove the coolant drain bolt (typically found on the water pump cover on the right side of the engine). Allow the coolant to drain completely. It is normal for some bikes to require removal of a radiator hose instead, but the TC250 is equipped with a dedicated drain screw for this task.
- Flush (if needed)
For best results, flush the system with distilled water. Replace the drain bolt, pour in distilled water, and briefly start the engine. Shut off the bike, remove the drain bolt, and let the water drain out, taking old residue with it. Repeat if the drained water looks dirty.
- Replace the Drain Bolt
Once fully drained, reinstall and tighten the drain bolt securely. If the bolt uses a washer, inspect and replace if needed to prevent leaks.
- Refill with Fresh Coolant
Using a funnel, slowly fill the radiator with the proper mix of coolant until it reaches the top of the filler neck. Gently rock the bike from side to side to release any trapped air bubbles.
- Bleed the System
With the cap off, start the engine and let it idle for a few minutes. Check the radiator – if the level drops, top off until no more air burbles up. Shut off the bike and let the engine cool, then check and fill to the proper level once more.
- Final Checks
Reinstall the radiator cap. Inspect for leaks around the drain bolt, hoses, and radiator. Wipe up any spills and properly dispose of the old coolant and flush water according to local regulations.
Model-Specific Notes for the 2016 Husqvarna TC250
- This model features a lightweight, high-compression engine that heats up quickly under aggressive riding. Use a premium, dirt bike-specific coolant to maximize protection.
- Inspect the cooling system hoses and T-pipe for signs of wear or cracking – aged hoses are more prone to leaks on 2016 models and easily replaced during coolant service.
- Consider upgrading to reinforced or high-flow hoses for enhanced reliability if you ride hard or in hot conditions.
- The 2016 TC250's cooling efficiency is essential for engine longevity. Look for proper coolant level before every ride and after each service.
- If you ride in freezing temperatures, confirm that the coolant mixture provides adequate freeze protection. Standard dirt bike coolant is usually adequate, but verify the spec on the coolant bottle.
Regularly changing your coolant safeguards your 2016 Husqvarna TC250’s engine health and keeps your performance sharp every time you hit the track. For genuine parts, replacement hoses, high-performance coolant, and more, MotoSport has your back.
