How to Change the Coolant in a 2014 GAS GAS TXT RACING 125
Maintaining the cooling system of your 2014 GAS GAS TXT RACING 125 is essential for optimal performance and engine longevity. Changing the coolant regularly – typically once a year or as needed – helps prevent overheating, corrosion, and internal scale buildup. Below is a step-by-step guide tailored to your TXT RACING 125, along with important tips specific to this model and best practices for dirt bike owners.
Prepare Your Workspace & Gather Supplies
- OEM-approved coolant or a high-quality motorcycle-specific antifreeze
- Basic hand tools (socket/wrench set, pliers)
- A clean drain pan
- Shop rags and safety gloves
Always change coolant with a cold engine to avoid burns from hot fluid or steam.
Draining the Coolant
- Locate the radiator cap (typically on top of the left radiator) and the coolant drain bolt or hose at the lowest point in the cooling system.
- Remove the radiator cap slowly to release pressure.
- Place your drain pan under the drain point. Loosen the drain bolt or hose clamp, letting all coolant flow into the pan.
- Inspect coolant for contamination – dirty, rusty, or milky fluid may indicate other system issues.
Flush the System (Recommended)
- To fully remove old coolant and debris, fill the system with distilled water after draining, then run the engine briefly (just until water circulates, not getting hot).
- Shut off, allow to cool, and drain again.
Refilling With New Coolant
- Reinstall and securely tighten the drain bolt or hose.
- Pour the proper mixture of coolant (consult your owner's manual, but 50/50 premix is typical) slowly into the radiator until full.
- Briefly tilt and rock the motorcycle to help air escape from the system. Top off as needed.
- Reinstall the radiator cap firmly.
Bleeding and Checking for Air
- Start the engine and let it idle. Watch for bubbles in the radiator (if cap is off) or listen for gurgling. Shut down, allow to cool completely, and recheck the level. Add more coolant if necessary to reach the base of the filler neck.
- Inspect the overflow/expansion reservoir – top off if needed, as fluid may shift between the radiator and reservoir as the engine heats and cools.
2014 GAS GAS TXT RACING 125 Model-Specific Tips
- The TXT RACING 125 is a competition-focused trials bike, so lightweight components and compact cooling system design mean accessible service but less fluid volume compared to trail bikes.
- Regularly check hoses and clamps for leaks or wear, as the tight packaging can lead to chafing or loosened fittings, especially after hard riding.
- Due to low coolant capacity, minor leaks or low coolant can cause temperature spikes quickly, so inspect before every event or ride.
- The recommended change interval is typically once a year, but in harsh or competitive environments, consider changing more frequent.
- If riding in cold climates, ensure your coolant mix provides adequate freeze protection for winter months.
Final Inspection – Ready to Ride
- Check for leaks around the drain, hose connections, and radiator cap.
- Monitor coolant level after your first ride, as remaining air bubbles may affect the fluid level.
- Never overfill – leave space in the radiator/reservoir for expansion.
The 2014 GAS GAS TXT RACING 125, with its performance-oriented cooling design, rewards attentive maintenance. Follow these steps for reliable operation and peace of mind no matter where your next trial takes you.
