Maintaining the cooling system of your 2017 Husqvarna TE150 is essential for engine performance and longevity, especially when tackling tough off-road terrain. Below you'll find a step-by-step guide to changing your coolant, with specific notes for this model to ensure safe and reliable operation.
What Owners Should Know About the TE150
- Engine Type: The 2017 TE150 uses a high-output 144cc two-stroke engine that relies heavily on coolant for temperature control during aggressive riding or slow technical trails where airflow is reduced.
- Frame and Chassis: Its high-strength chromoly steel frame and WP suspension make it ideal for rough terrain, but mud and debris can accumulate around the radiators, so check for blockages during coolant changes.
- Cooling System Tip: This bike utilizes a compact, closed-loop cooling setupany air bubbles left in the system can lead to overheating, so be diligent when refilling.
Tools & Supplies Needed
- Fresh engine coolant (use a high-quality product compatible with aluminum engines)
- Drain pan
- 8mm wrench or socket
- Funnel
- Rags for cleanup
- Protective gloves and eyewear
- Replacement crush washer for the drain bolt (optional, but recommended)
Step-by-Step Coolant Change Instructions
- Let the engine cool completely before starting. Never open the radiator cap on a hot engine–the system is under pressure and hot coolant can spray out dangerously.
- Remove the right shroud or panel (if necessary) for easy access to the radiator cap and drain bolt.
- Position a drain pan beneath the water pump drain bolt, located on the lower right side of the engine case.
- Remove the coolant drain bolt. Use an 8mm wrench to loosen but keep the radiator cap installed for now. This controls the flow and prevents coolant from spilling out rapidly.
- Slowly remove the radiator cap. With the drain bolt out, now open the radiator cap to allow air in and coolant to drain completely into your pan. This method limits splashing and mess.
- Inspect the drain bolt washer. Replace the crush washer if it appears damaged or worn to prevent future leaks.
- Reinstall the drain bolt. Tighten it firmly, but do not overtighten to avoid damaging the threads.
- Add new coolant. Using a funnel, slowly fill the radiator with fresh coolant until it reaches the top of the radiator neck.
- Bleed the system of air. Gently rock the bike side to side or squeeze the upper radiator hose to help dislodge any trapped air.
- Reinstall the radiator cap. Make sure it is secure.
- Start the engine and idle for a few minutes. Allow the bike to reach operating temperature. Shut it off, let it cool, and check coolant level again. Top off if necessary.
Extra Model-Specific Notes
- Always check for mud or debris packed in the radiators after rides, as this can reduce cooling efficiency.
- The TE150 has efficient brakes and compact radiators–if you notice consistent overheating or coolant loss, inspect for leaks or blockages as part of routine maintenance.
- Use coolant compatible with aluminum radiators and internal components. Avoid mixing types unless labeled as compatible.
Regular coolant changes will keep your Husqvarna TE150 running at peak performance for every trail ride and race.
