How to Change the Coolant in a 2010 GAS GAS TXT PRO 280
Regular coolant changes are essential to keep your 2010 GAS GAS TXT PRO 280 running cool during technical trials rides. Below is a step-by-step guide uniquely for MotoSport customers, covering specific features and tips for this model. Always work with a cool engine to prevent scalding – the cooling system can be under pressure even after short use.
What Makes the GAS GAS TXT PRO 280 Unique
- This model uses a lightweight aluminum radiator system, making coolant maintenance crucial for maximum cooling efficiency.
- Coolant capacity is compact, so regular checking and timely replacement are even more important to prevent overheating.
- The radiator cap is located under the front of the fuel tank – removal of the fuel tank is usually necessary for access.
Tools & Materials Needed
- Phillips or Allen screwdrivers (for tank removal)
- Drain pan
- Hose clamp pliers
- Fresh coolant suitable for lightweight alloy engines (50/50 premix antifreeze/coolant rated to at least −30°C)
- Rags and cleaning supplies
Step-by-Step Coolant Change Procedure
- Ensure the engine is completely cool.
Never open the radiator cap while the engine is warm, as hot coolant and steam can cause injury. - Remove the fuel tank for access:
- Turn off the fuel tap and detach the fuel hose.
- Loosen and remove the front tank mounting bolt (typically an Allen M4 screw).
- Lift the tank from the front, disconnect any electrical connectors as required, and set the tank aside.
- Locate the radiator cap and drain point:
- The radiator cap sits at the high point, under where the tank was.
- For draining, look for the lowest hose connection on the engine water pump (usually left side). Many riders use the water pump cover drain bolt or gently loosen the lowest hose to drain the system.
- Open the radiator cap:
- Turn counterclockwise and remove. Place a clean rag around the neck to catch any overflow.
- Drain the coolant:
- Place a drain pan beneath the lowest coolant hose or drain bolt.
- Loosen the bolt or hose clamp and carefully disconnect, allowing coolant to fully drain out.
- Once drained, reattach the hose securely (or retighten the drain bolt with its sealing washer if present).
- Flush if desired:
- If old coolant was dirty or contaminated, refill with distilled water, run the engine briefly, allow to cool, then drain again.
- Refill with new coolant:
- Slowly fill the radiator to the top with high-quality coolant designed for lightweight alloy engines. Leave about 1 cm air at the top to allow for expansion.
- Put the cap back on loosely, start the bike, and let it idle for a minute to allow any air bubbles to work through.
- Top off, bleed, and reassemble:
- Turn off the bike, let it cool, then remove the cap and check the level. Top off as needed.
- Double-check for leaks at all clamps and connections.
- Reinstall the tank, reconnect fuel line and any connectors, and secure mounting bolts.
Tips for Owners
- Check for leaks or signs of corrosion after first ride following a coolant change.
- Avoid using tap water, as it may accelerate corrosion in the lightweight radiator and alloy components.
- If your TXT PRO 280 is used for hard trials or hot weather, inspect coolant level between rides for extra safety.
Proper coolant care protects the performance and longevity of your GAS GAS TXT PRO 280’s engine, giving you confidence out on the sections!
