How to Change the Coolant on a 2014 GAS GAS TXT RACING 250
Your 2014 GAS GAS TXT RACING 250 demands careful coolant maintenance to keep its advanced two-stroke engine running cool under pressure. Follow this step-by-step, model-specific guide from MotoSport to ensure safe, optimal coolant changes and avoid damage to internal components.
Why Coolant Changes Matter for the TXT RACING 250
Regular coolant changes prevent overheating and corrosion, critical in the TXT RACING 250’s high performance, lightweight frame, and advanced cooling system. This trial bike is engineered for competition, meaning proper coolant care directly affects throttle response, engine longevity, and clutch performance.
Preparation – What You Need
- Fresh liquid coolant (ethylene glycol-based, rated for motorcycles)
- Drain pan
- Clean funnel
- Gloves and eye protection
- Soft, clean cloths
- Socket set and screwdrivers
Important: Only begin the job with the engine completely cold to prevent scalding.
Step 1: Access the Cooling System
- Remove bodywork or panels as needed to reach the radiator cap and coolant hoses. The TXT uses a compact frame; remove carefully to avoid damaging any wiring or hoses.
Step 2: Drain the Old Coolant
- Place your drain pan beneath the water pump area.
- Slowly loosen the radiator cap to relieve pressure.
- Remove the lower radiator hose or open the designated drain bolt at the water pump to let all coolant flow into the pan. Allow several minutes for a complete drain.
- Inspect old coolant for signs of rust or oil contamination – these are warning signs requiring further engine inspection.
Step 3: Flush the System (Optional, For Thorough Cleaning)
- Replace hose/bolt temporarily, then fill the system with distilled water.
- Run the engine with the radiator cap off for two minutes, then drain again.
- Repeat until the water runs clear.
Step 4: Fill with New Coolant
- Re-secure all hoses and drains. Use the funnel to slowly fill the radiator up to the base of the filler neck, using the manufacturer’s recommended coolant volume and type.
- Inspect tubing and thermostat area for possible blockages and leaks while filling.
- Do not overfill. If your bike is equipped with an expansion tank, fill it to the max level as indicated.
Step 5: Bleed Air from the Cooling System
- With the radiator cap off, start the engine and allow it to idle until warm. Gently rock the bike side to side to release trapped air bubbles.
- Watch for air to escape and coolant to settle; top off as needed.
- Once warm, stop the engine, let it cool fully, and recheck fluid levels. Top off again if required.
Step 6: Reinstall Everything – Final Checks
- Secure the radiator cap.
- Reinstall bodywork or panels.
- Clean up any spilled coolant, as it is toxic to pets and the environment.
- Visually inspect the cooling system for leaks after your first ride.
Special Considerations for the 2014 TXT RACING 250
- Minimal radiator fan: This trial bike might not have a radiator fan like enduro models, which means proper coolant quality is even more critical to avoid overheating in slow, technical riding.
- Compact design: The cooling system is tightly packed; be gentle with hoses and clamps to prevent leaks.
- Periodic inspection: The manufacturer recommends regular checks of coolant, spark plug, and hose integrity for peak competition performance and to prevent costly engine damage.
Routine coolant replacement is integral for maintaining your TXT RACING 250’s performance. Keeping the system fresh ensures consistent engine temperatures, improved throttle response, and peace of mind on the trials courses.
