How to Change the Coolant in a 2009 GAS GAS TXT PRO 250
Changing the coolant in your 2009 GAS GAS TXT PRO 250 is an integral maintenance task to preserve optimal engine performance and durability. This trials bike requires periodic coolant changes to safeguard the lightweight alloy engine components and ensure peak operation during technical riding.
Preparation – Safety and Work Area
- Always perform coolant changes with the engine completely cool; removing the radiator cap or hoses when hot can cause severe scalding.
– Be mindful: the TXT PRO 250's compact frame makes access tight, so plan for controlled draining and minimal spillage. - Work in a well-ventilated area and gather absorbent materials to contain any coolant runoff.
- Use genuine or high-quality coolant formulated for lightweight alloy motorcycle engines – this is crucial to prevent corrosion inside the Gas Gas cooling system.
Tools & Supplies Needed
- 8mm and 10mm sockets or Allen keys (for plastics or tank removal as needed)
- Drain pan suited for coolant
- Funnel for refilling
- Replacement crush washer for the drain bolt (recommended each change)
- Fresh coolant (compatible with lightweight alloy engines, typically capacity near 1 liter)
Step-by-Step Coolant Change
-
Remove the Gas Tank (if needed): To access the radiator and drain points, first ensure the fuel tap is turned off. Remove the fuel tube, unscrew the front upper Allen bolt, lift the tank, and set aside.
-
Locate the Radiator and Drain Bolt: On the lower left side of the engine crankcase, find the coolant drain bolt.
-
Position a Pan – Loosen Drain Bolt: Place your pan under the drain point. Loosen the bolt carefully. Removing the radiator cap will speed draining; do so only when the engine is absolutely cool.
-
Flush Old Coolant: Let all liquid drain into the pan. Inspect the crush washer and replace if worn – a new washer helps prevent leaks. After draining, thread the bolt back in and torque to manufacturer specs (typically around 10 Nm).
-
Refilling: Insert a funnel into the radiator opening and pour new coolant until it reaches near the fill line, above the radiator fin – avoid overfilling. The TXT PRO 250 typically requires about 0.95 liters (1 US quart) of coolant.
- Bleed – Check for Air: Start the engine briefly with the radiator cap off, allowing air bubbles to escape. Top off the coolant if the level drops. Replace the cap securely.
- Final Inspection: Look for leaks at the drain bolt and hoses. Reinstall the fuel tank and check all fasteners. Dispose of old coolant responsibly.
Model-Specific Notes
- The 2009 TXT PRO 250's cooling system is engineered to protect lightweight alloy engine cases, so using the correct coolant type is critical.
- Careful routing of hoses and proper torque on the drain bolt are key to preventing leaks in the compact TXT layout.
- If you need to access the carburetor or clutch for related servicing, remove the air filter box for improved access.
- Regularly inspect coolant level & clarity each ride; replace at least once per season or after heavy use.
