How to Change the Coolant in a 2025 Husqvarna TE150: MotoSport's Step-by-Step Guide
Shop parts for a 2025 Husqvarna TE150 Dirt Bike.
The 2025 Husqvarna TE150 stands out as a lightweight, high-performance enduro motorcycle with its advanced throttle-body fuel injection system, innovative power valve design, and CFD-developed radiators for efficient cooling. Keeping your TE150’s cooling system in peak shape is essential for power delivery, engine longevity, and reliable performance on the trail . This proprietary MotoSport guide will outline a robust process for changing the coolant specifically for your model.
What Makes Cooling System Maintenance Vital on the 2025 TE150?
- High-efficiency radiators: The TE150's radiators are designed to maximize airflow and cooling, but they require periodic coolant changes to avoid corrosion and mineral buildup .
- Modern engine technology: Fuel injection and the advanced cylinder demand stable engine temps for optimal combustion and reduced emissions .
- Electronic oil injection: The electronic oil pump and reed cage design depend on a consistently cooled engine for top reliability .
Tools & Supplies Needed
- Fresh, high-quality motorcycle coolant (silicate-free, pre-mixed or concentrated if mixing with distilled water)
- Drain pan
- 8mm or 10mm wrench (confirm drain bolt size visually)
- Rag or towels (for spills)
- Funnel
- New drain bolt washer (strongly recommended to prevent leaks)
Step-by-Step: Changing the Coolant
- Let the bike cool completely. Open the radiator cap slowly to relieve pressure.
- Place a drain pan under the water pump–typically on the right side of the engine.
- Remove the coolant drain bolt (usually located at the bottom or side of the water pump housing) and let the coolant drain.
- To speed draining and allow more coolant out, remove the radiator cap after removing the drain bolt. This helps break the vacuum, allowing coolant to flow out fully.
- Inspect and replace the drain bolt washer as needed before reinstalling.
- Reinstall and torque the drain bolt securely. Clean up any spilled coolant.
- Using a funnel, fill the radiators with new coolant. Fill slowly and gently squeeze the coolant hoses to burp out trapped air.
- Fill close to the neck of the radiator cap but do not overfill.
- Replace the radiator cap securely.
- Start the engine and let it idle for several minutes. Watch the coolant level, top off as necessary after the engine warms up and settles.
- Check the system for leaks at the drain bolt and hose connections.
TE150-Specific Tips
- Coolant hose routing: The compact, mass-centralized design may require removing or moving hoses for better access to the drain bolt.
- Piston cleaning: If doing major maintenance (like top-end work), note cylinder locating pins as they can dislodge–always keep the area clean to prevent parts from falling into the engine.
- Radiator material: High-strength aluminum coolers demand silicate-free coolant to avoid electrolysis and corrosion .
When to Change Coolant on Your 2025 TE150
- At least every 24 months, or as directed in your service manual.
- After heavy or muddy riding where debris might enter the radiator or coolant system.
- If you notice signs of overheating, discolored coolant, or leaks.
Disposal
Properly dispose of used coolant at a recycling center or hazardous waste facility. Never pour it down drains or onto the ground.
