Shop parts for a 2015 Husqvarna TE300 Dirt Bike.
Maintaining your 2015 Husqvarna TE300 is essential for peak performance – and one of the most straightforward but important tasks is changing the coolant. Whether you are prepping for a new riding season or your coolant is past its prime, follow these MotoSport-specific instructions to keep your cooling system running strong. The TE300’s robust two-stroke engine relies on effective cooling, so do not overlook this critical maintenance step.
What You Need
- Fresh coolant, ideally blue G11 type (OE specification) or a high-quality aftermarket equivalent formulated for aluminum engines
- Drain pan
- Screwdrivers or socket set (for radiator cap & drain bolt removal)
- Shop rags
- Protective gloves
- Distilled water for flushing (optional but recommended for complete flushes)
Important TE300 Model Notes
- OE coolant from Husqvarna is typically blue G11 (Agip Cool), designed for aluminum engine components
- Mixing coolant types is not recommended — always verify what is in your system before topping off or refilling
- The 2015 TE300 features dual radiators connected in parallel; ensure drainage from both sides
- Never open the radiator cap on a hot engine. Let the engine fully cool before starting this task
Step-by-Step Coolant Change Process
- Engine Off & Cool: Ensure your engine is completely cold. Place your TE300 on a stable, level surface or stand.
- Remove the Radiator Cap: Slowly remove the radiator cap to release any pressure. This allows air in and helps the coolant drain smoothly.
- Drain the Old Coolant: Locate the coolant drain bolt (typically on the lower water pump cover) or, if not present, disconnect the lower radiator hose. Position your drain pan underneath and remove the bolt or hose, letting coolant drain from both radiators. Tilt the bike slightly to ensure all coolant exits.
- Flush the System (Optional): If doing a full flush, fill the system with distilled water, reinstall the cap and drain bolt/hose, and briefly run the engine at idle (1–2 minutes). Shut off, let cool, and drain again completely. Repeat until only clear water drains out.
- Reinstall Components: Secure the drain bolt or radiator hose and ensure all clamps are tight.
- Add New Coolant: Pour in the recommended coolant slowly through the radiator cap opening. Fill until the fluid level sits just below the neck of the opening, with space for expansion. For the TE300, use the blue G11 coolant or a suitable motocross/2-stroke compatible alternative.
- Remove Air Pockets: Gently rock the bike side to side and squeeze radiator hoses to help dislodge air bubbles. Top off as needed to the correct level.
- Reinstall the Radiator Cap: Securely refit the radiator cap.
- Warm Up & Recheck Level: Start the bike and let it idle for a few minutes. Watch for leaks and monitor the coolant level in the overflow bottle (if equipped). Once cooled, check the level again and top up if necessary.
- Dispose of Old Coolant Properly: Used coolant contains chemicals harmful to people & pets. Recycle or dispose of it at your local hazardous waste center.
MotoSport Tip
Always inspect radiator hoses and clamps during the coolant change. Any cracks, swelling, or brittleness can lead to leaks – replacement parts are available for your 2015 TE300 through MotoSport.
Model-Specific Advice for the 2015 TE300
- For aggressive off-road and enduro riding, some owners prefer performance coolant brands, but ensure compatibility with aluminum internals
- The cooling capacity of the TE300 is robust, but radiators can become clogged with mud & debris on tough trails. Clean fins gently with compressed air or a soft brush when performing coolant service
