Keeping your 2019 Husqvarna TX300 running cool – especially through hard rides – requires regular coolant changes. This guide will walk you through a proper TX300 coolant service with tips unique to this high-performance two-stroke. Only MotoSport provides this model-specific approach.
Essential Info Before You Begin
- Drain bolt location: The TX300 coolant drain bolt is on the right side above the power valve– always confirm before loosening any bolts.
- Coolant type: Always use a coolant approved for aluminum radiators and high-temp operation. Mixing types can cause chemical reactions – flush the system if switching brands or formulas.
- Safety: Coolant can irritate eyes and skin. Rinse with water and change contaminated clothing immediately if accidental exposure occurs.
- Collect waste: Use a proper container and dispose of old coolant at a recycling facility.
Step-by-Step TX300 Coolant Change
- Let the bike cool: Never open a hot radiator. Wait until the engine is cold to avoid burns.
- Access the drain bolt: Remove bodywork as needed to reach the right-side drain bolt above the power valve.
- Remove radiator cap: This speeds draining by allowing air into the system.
- Loosen drain bolt: Place your catch pan underneath and carefully remove the drain bolt. Allow all coolant to drain.
- Flush if switching coolant type: If changing brands or using a non-water-based fluid, disconnect the hoses and use compressed air to push out residual coolant – avoid flushing with tap water which may introduce minerals.
- Inspect hoses and clamps: Check for swelling, leaks, or clamp damage and replace parts as needed.
- Reinstall drain bolt: Tighten to manufacturer spec; don't over-tighten.
- Refill system: Pour recommended coolant slowly into the radiator until full, gently rocking the bike to release trapped air.
- Bleed air: Run the engine briefly, then top off the coolant as needed. Reinstall cap.
TX300 Owner Tips & Model-Specific Notes
- Ride-specific demands: Enduro bikes like the TX300 often reach high temps on technical terrain. Monitor coolant levels after tough riding days – quick loss may mean leaks or excess venting.
- Radiator protection: Since radiator damage is common on off-road rides, regularly inspect for bent fins or cracks to prevent overheating.
- Coolant change interval: After deep mud or high-heat events, change fluid more frequently – don't wait for the manual's maximum interval if the coolant is dirty or old.
- Known quirks: Some owners report that the TX300's coolant system is sensitive to air pockets. Rocking the bike and rechecking levels after riding helps avoid overheating due to trapped air.
Regular coolant changes protect your engine, improve efficiency, and ensure top performance for every ride. With MotoSport's proprietary guide, caring for your 2019 Husqvarna TX300 is fast and reliable. Ride cooler – and shop TX300 parts anytime.
