How to Change the Coolant in a 2011 GAS GAS TXT PRO 280
Changing the coolant on your 2011 GAS GAS TXT PRO 280 is part of routine maintenance that ensures your engine stays cool and protected against wear. This model uses a liquid-cooling system suited for high-performance trials riding, with light alloy engine components that require proper coolant to prevent corrosion and overheating.
Important Precautions
- Only change coolant when the engine is completely cold to prevent severe burns or scalding from pressurized hot fluid.
- Always use a coolant designed for light alloy engines to avoid internal damage and scale build-up within the cooling system.
Required Tools & Supplies
- Drain pan
- Screwdrivers (flat and Phillips)
- Pliers
- Fresh coolant for aluminum engines
- Clean shop towels
- Protective gloves
Step-by-Step Instructions
- Ensure engine is cold before beginning. Remove the fuel tank if better access to the radiator and hoses is needed (consult your manual for fuel line disconnection procedure).
- Remove the radiator cap. Turn it slowly to release any built-up pressure. Never attempt this on a hot engine for safety reasons.
- Locate the coolant drain point. On most TXT PRO 280 models, this is found at the lowest hose connection on the water pump cover. Place a drain pan beneath this area.
- Loosen the clamp securing the lower water pump hose, then carefully pull the hose off. Allow all old coolant to drain completely. Leave the drain open for several minutes, tilting the bike slightly if needed to help clear out trapped fluid.
- Inspect the hoses and clamps. Now is a good time to look for cracks, brittleness, or corrosion. Replace any suspect parts to prevent future leaks.
- Reattach the hose securely and tighten the clamp.
- Slowly fill the radiator with fresh coolant designed for use with light alloy engines. Pour until the fluid just covers the radiator core. Allow air bubbles to escape; rock or gently shake the bike to help trapped air percolate upward.
- Reinstall the radiator cap once the level is steady and correct.
- Start the engine and let it idle for several minutes. Watch for leaks. The coolant level may drop slightly as trapped air escapes – shut off the motor after warming up, allow it to cool, and top off coolant as needed.
- Safely dispose of old coolant. Never pour used antifreeze down the drain or on the ground. Most auto parts stores accept used coolant for recycling.
Special Notes for 2011 GAS GAS TXT PRO 280 Owners
- The 2011 model features an updated kickstart shaft design to fit its wider frame. Take care not to disturb the kickstart mechanism when removing the clutch or water pump cover. Lightly pull the kickstart shaft while removing the cover to avoid accidental disengagement*.
- Regularly check and maintain coolant level between changes, especially after long rides or exposure to high heat.
- If the engine is ever overheated, inspect all coolant passages and hoses for residue and blockages before adding fresh fluid.
A proactive approach to cooling system care will keep your GAS GAS TXT PRO 280 running at peak performance season after season.
