How to Change the Coolant in a 2010 GAS GAS TXT PRO 300
Shop parts for your ride now!Routine coolant changes are vital for the longevity and consistent performance of your 2010 GAS GAS TXT PRO 300. Dirt bike cooling systems are exposed to extreme operating temperatures and lightweight aluminum components–fresh coolant prevents corrosion and ensures efficient engine cooling. This straightforward process will guide you through changing the coolant on your TXT PRO 300, focusing on steps and precautions specific to your model.
What Makes the 2010 GAS GAS TXT PRO 300 Unique?
- The TXT PRO 300 uses a high-performance, lightweight alloy engine requiring non-corrosive coolant specifically blended for aluminum motorcycle engines.
- Access to the radiator and cooling system is straightforward thanks to a removable fuel tank and minimalist bodywork, but always allow the engine to cool completely before accessing any part of the cooling system to avoid burns and scalding fluids. – Owners should note the proximity of chassis components when removing the fuel tank and ensure vent hoses are routed free of kinks when refitting parts after service.
Tools & Supplies Needed
- Fresh coolant (for lightweight aluminum motorcycle engines, rated to at least -30°C)
- Socket set and Allen keys
- Flat-head screwdriver
- Catching pan for old coolant
- Rags for cleanup
- Safety gloves and eye protection
Step-by-Step: Changing the Coolant
-
Ensure Safety First:
- Make sure the engine is stone cold before beginning to prevent injury from hot fluid.
- Work on a stable, well-ventilated surface.
-
Remove the Fuel Tank (if necessary for access):
- Turn off the fuel valve and remove the fuel hose from the cock.
- Unscrew the Allen screw (front upper tank mount) and lift the tank from the chassis.
-
Access the Radiator Cap:
- Carefully remove the radiator cap by turning it counterclockwise. Never open the radiator cap while the engine is hot – the system is pressurized and can cause severe burns.
-
Drain the Old Coolant:
- Locate the coolant drain bolt on the lower left side of the engine or at the base of the water pump*.
- Place a catch pan beneath the drain point and remove the bolt to let all coolant drain completely.
- Gently rock the bike side-to-side to expel any remaining coolant.
*If your model does not have a dedicated drain bolt, you can disconnect the lower radiator hose closest to the engine case to drain the coolant.
-
Inspect and Replace Seals (Optional but Recommended):
- While the system is open, check for fissures or wear in any hoses, clamps, or the radiator cap seal. Replace if necessary for trouble-free operation.
-
Re-fit Drain Bolt/Hose:
- Once drained, reinstall the drain bolt (with washer) or reconnect the hose and securely tighten.
-
Refill With New Coolant:
- Pour new coolant slowly into the radiator opening until fluid just reaches the base of the fill neck.
- Gently rock the bike again to release trapped air bubbles; top up as needed.
- Securely reinstall the radiator cap.
-
Reinstall the Fuel Tank and Test:
- Place the fuel tank back in the chassis and reconnect mounting screws and the fuel line.
- Start the engine and let it run for several minutes. Watch for leaks and check the coolant level again after the bike cools.
Additional Tips for Your TXT PRO 300
- Use only coolants rated for aluminum engines to prevent internal corrosion.
- Change coolant at least every two years, or more frequently if you ride in wet or muddy conditions.
- Check the spark plug gap and air filter during regular maintenance for optimal performance.
- Consult your owner's manual for torque specifications and fluid capacities to extend the life of engine components.
With proper coolant maintenance, your 2010 GAS GAS TXT PRO 300 will continue to deliver precision performance through every trial section.
