How to Change the Coolant in a 2015 GAS GAS TXT PRO 280
Routine maintenance of your GAS GAS TXT PRO 280 is crucial for reliable performance, especially in demanding off-road conditions. Coolant replacement not only protects the engine from overheating but also prevents internal corrosion and component wear. Here's the proprietary MotoSport guide to changing the coolant on your 2015 GAS GAS TXT PRO 280, including model-specific considerations every owner should know.
Essential Tools & Supplies
- Fresh, high-quality coolant formulated for lightweight alloy motors (choose premix or mix with distilled water to manufacturer's spec, usually -30°C rated)
- Socket set with Allen keys
- Drain pan
- Clean rags and gloves
- Funnel
Preparation & Safety
- Allow the engine to cool completely – opening the system when hot can cause severe burns and damage components.
- Set the bike upright and secure it on a stand for stability and safe access.
Step 1: Remove the Fuel Tank for Access
- Close the fuel valve (petcock) and disconnect the fuel line from the tank.
- Remove the upper mounting Allen screws of the fuel tank.
- Lift the front of the tank and carefully set it aside, exposing the radiator fill and plumbing.
Step 2: Drain the Coolant
- Locate the coolant drain bolt, usually at the lowest point of the water pump housing on the left side of the engine case.
- Position a drain pan under the bolt. Remove the drain bolt slowly and allow coolant to fully empty from the system.
- Remove the radiator cap to speed drainage and allow atmospheric pressure to assist in emptying the system.
- Inspect the used coolant for debris or discoloration – milky or rusty coolant could indicate a leak or deeper service need.
Step 3: Flush the System (Optional but Recommended)
- Pour distilled water into the radiator and re-install the drain bolt temporarily. Start the engine briefly (under 30 seconds), then shut it off and drain again.
- Repeat as needed until only clear water drains out, ensuring all old coolant and possible contaminants are removed.
Step 4: Refill with Fresh Coolant
- Ensure the drain bolt and any seal washer are reinstall with proper torque (do not overtighten).
- Pour fresh coolant slowly into the radiator filler neck. Fill until it is level with the bottom of the neck.
- Tilt the bike gently side to side to purge air pockets from the system.
- Reinstall the radiator cap securely.
Step 5: Bleed & Check for Leaks
- Start the engine and let it idle for several minutes. Watch for bubbles at the filler or overflow, indicating trapped air is escaping.
- Shut off the engine. Allow to cool, then recheck and top off coolant if needed.
- Check all hoses, clamps, and the drain bolt for leaks.
Model-Specific Notes for the 2015 TXT PRO 280
- This model features a lightweight aluminum engine; always use an appropriate coolant to prevent corrosion and overheating of alloy components.
- Small overall capacity means service intervals should be respected, especially after hard or extended riding in hot conditions.
- The radiator is compact, so avoid overfilling – excess coolant will escape through the overflow.
- Inspect the radiator cap seal and hose condition during each change. Replace as needed for best system health.
Regular coolant service on your TXT PRO 280 ensures performance, keeps temperatures in check, and protects expensive engine internals. Proper maintenance and attention to detail can extend the service life of your ride and ensure you're always ready for the next section of the trail.
