Shop parts for a 2022 Husqvarna TE150i Dirt Bike.
Routine coolant changes are essential for the longevity and performance of your 2022 Husqvarna TE150i. This innovative 2-stroke enduro bike is built for demanding off-road conditions, and its advanced cooling system needs clean, fresh coolant to prevent overheating and corrosion. Follow this proprietary MotoSport guide for a safe and thorough coolant change. Always ensure your bike is cool before starting – never open the cooling system while hot.
What Makes the 2022 TE150i's Cooling System Unique?
The TE150i features a lightweight frame and a robust engine, with a large center tube running through the frame to optimize coolant flow. This design reduces pressure points for consistent temperature management, crucial during intense rides. The engine management system is highly refined, using sensors and an ECU for automatic temperature compensation, which means the coolant quality is vital for accurate thermal regulation and performance over varying altitudes and conditions. The radiator and associated connections are engineered for quick, accessible service - perfect for riders who perform their own maintenance.
Tools & Supplies You'll Need
- New coolant specifically formulated for motorcycles – check your owner's manual for specs
- Basic hand tools (sockets, flathead screwdriver, pliers)
- Drain pan
- Funnel
- Clean rags
- Protective gloves and safety glasses
Step-by-Step Coolant Change Instructions
- Preparation: Make sure the engine is completely cool before proceeding. Place the bike upright on a stand and remove the seat and side shrouds if necessary for easier radiator access.
- Remove the Radiator Cap: Slowly unscrew the radiator cap to relieve any residual pressure.
- Locate and Remove the Drain Bolt: The coolant drain bolt is typically found on the lower part of the water pump or engine case on the right side. Position a drain pan underneath and carefully remove the drain bolt & sealing washer. Allow all coolant to drain completely.
- Flush the System (Optional but Recommended): For best results, flush the system with distilled water. Pour distilled water into the radiator, reinstall the drain bolt temporarily, run the engine briefly, then repeat the drain step to remove residues.
- Inspect and Reinstall the Drain Bolt: Check the sealing washer for wear and replace if needed. Reinstall and tighten the drain bolt securely.
- Add Fresh Coolant: With a funnel, pour new coolant into the radiator slowly, allowing air to escape. Fill to just below the neck of the radiator.
- Bleed Air from the System: Gently squeeze the radiator hoses to release trapped air. If your TE150i has a bleeder screw on the thermostat or head, loosen it until only fluid - not air - escapes, then retighten.
- Reinstall the Radiator Cap: Ensure the cap is clean and free of debris before tightening.
- Check for Leaks & Top Off: Start the engine and let it idle until fully warm. Shut it off, allow it to cool, and recheck the coolant level. Add fluid if necessary for the perfect level - just below the cap seat.
- Replace All Covers: Reattach seat and shrouds as required.
Expert Model-Specific Tips
- The 2022 TE150i's advanced ECU relies on accurate temperature readings. Always use the correct coolant mixture for this model to ensure the sensors provide reliable data.
- Inspect hoses and clamps during coolant changes for signs of aging or wear – the cooling system's efficiency depends on full integrity.
- A low seat height and centralized components make this model easier to work on compared to many other enduro bikes.
- The lightweight lithium-ion battery and electrical harness are located just below the seat. Disconnect the battery if spilling coolant to avoid electrical shorts.
Follow these instructions for reliable performance and peace of mind on the trail. With MotoSport-exclusive guidance and parts support, your 2022 Husqvarna TE150i will stay adventure-ready all season long.
