Shop parts for a 2016 Husqvarna TE300 Dirt Bike.
The 2016 Husqvarna TE300 is a legendary two-stroke built for serious enduro enthusiasts, prized for its lightweight handling and reliable engine. Proper cooling system maintenance is vital for performance and engine longevity–overheated motors can cause irreversible damage and hurt race day reliability. This step-by-step MotoSport exclusive guide will walk you through a complete coolant change, highlighting critical notes specific to your TE300.
What You'll Need
- Fresh coolant suitable for aluminum engine components (silicate-free preferred for modern two-strokes)
- Drain pan
- Socket set (10mm for drain bolt)
- New copper washer for drain bolt (recommended)
- Distilled water (if flushing the system)
- Basic hand tools and shop rags
- Protective gloves & eyewear
Preparation
- Ensure your TE300 is cool to the touch and parked upright on a stable stand.
- Remove the radiator shrouds and seat for easier access to the radiators and cap.
Step-by-Step Coolant Change
-
Open the Radiator Cap:
Slowly open the radiator cap to relieve any residual system pressure. Always do this first, as trapped pressure can result in hot coolant spray. -
Locate the Coolant Drain Bolt:
On the 2016 TE300, the main coolant drain bolt is found at the water pump cover–look for the bolt with the copper washer. Position your drain pan underneath. -
Remove the Drain Bolt:
Using your 10mm socket, carefully loosen the drain bolt. Allow the coolant to fully drain from the engine and radiators. Tilting the bike gently side-to-side can help evacuate all the fluid. -
Optional: Flush the System
If you're changing coolant types or want a thorough flush, reinstall the drain bolt temporarily and fill the system with distilled water. Run the engine briefly (30-60 seconds), then repeat steps 1–3 to drain the water. Do not use tap water–minerals can damage the cooling system. -
Reinstall the Drain Bolt
Install a new copper washer if available, torque the bolt to spec (consult your owner's manual for recommended torque), and clean off any spills. -
Refill with Fresh Coolant
Pour in coolant until it reaches the base of the filler neck. Squeeze the radiator hoses gently to help release trapped air. -
Bleed the System ("Burp the Radiator")
With the cap still off, start the bike and let it idle for several minutes. Gently rock the bike and blip the throttle occasionally. This helps any remaining air bubbles escape. Top off the coolant as needed. -
Check and Replace the Radiator Cap
Once the level is steady and no more bubbles rise, reinstall the radiator cap securely. -
Check for Leaks & Test Ride
Inspect all connections, hoses, and the drain bolt for leaks. Reinstall the shrouds and seat. Take a short test ride, then re-check the coolant level and top off if necessary.
Notes Specific to the TE300
- Radiator Fan (if equipped): Some TE300s come with auxiliary fans–ensure the electrical connector is secure and no coolant has leaked onto wiring during the process.
- Coolant Capacity: The TE300 holds roughly 1.0 liter in its cooling system. Overfilling will cause coolant to spill during thermal expansion.
- Coolant Type: Use high-quality coolant formulated for aluminum radiators to prevent corrosion and electrolysis. Pre-mixed or a 50/50 solution (if concentrate) is ideal.
Disposal
Never pour old coolant down the drain or on the ground. Bring used coolant to a local recycling center or auto parts store that accepts hazardous waste.
Final Tips
- Check hoses and radiator for signs of wear or leaks–replace as needed.
- Record the coolant change in your maintenance log for future reference.
