How to Change the Coolant in a 2023 GAS GAS TXT RACING 300: Complete Guide
Keeping your 2023 GAS GAS TXT RACING 300 running cool is essential for top performance and engine longevity. A regular coolant change ensures reliable protection against overheating and corrosion. Below is a step-by-step guide, proprietary to MotoSport, to help you change the coolant safely and efficiently on your 2023 TXT RACING 300 – with key notes for this exact model.
What You Need
- Proper engine coolant (compatible with aluminum radiators; check for silicate-free and non-ethanol blends)
- Basic hand tools (socket set, pliers, screwdrivers)
- Drain pan
- Funnels and shop towels
- Gloves and safety glasses
Preparation
- Allow the engine to cool completely before starting. Opening the radiator cap on a hot engine can cause severe burns from steam or heated coolant—never skip this precaution.
- Place the TXT Racing 300 securely on a stand on level ground.
Draining the Old Coolant
- Locate the radiator cap (usually at the top, near the frame) and the coolant drain bolt at the water pump area.
- Remove the radiator cap slowly to relieve pressure.
- Position the drain pan under the water pump.
- Use a socket to loosen and remove the coolant drain bolt. Allow coolant to fully drain from the system. Tilting the bike gently side to side ensures more thorough draining of both radiators.
- If accessible, open any available bleeder screw on top of the cylinder head to help air escape and speed draining.
Flushing (Optional but Recommended)
- If the old coolant is visibly contaminated or the last change is unknown, flush the system with distilled water. Reinstall the drain bolt, fill the system with distilled water, run the bike for a few minutes, then drain again. Repeat until clear.
Filling the System with New Coolant
- Ensure the drain bolt and any bleeder screws are reinstalled and torqued to spec (consult the manual for values specific to the TXT 300).
- Pour fresh coolant slowly into the radiator until it reaches the neck.
- On the TXT RACING 300, it's important to fill through the radiator cap opening and also crack open the cylinder head bleeder screw (if equipped) to release trapped air. When coolant starts to come out of the bleeder screw, retighten it immediately.
- Check and top off until the level stays consistent at the radiator neck.
Bleeding the Cooling System
- Start the engine and let it idle with the radiator cap off. As the engine warms, trapped air will rise and may bubble out. Add coolant as needed until the bubbling stops and the level remains steady.
- Once air is purged, install the radiator cap securely.
- Inspect for leaks around the drain bolt and hose connections and wipe up any spills.
Final Checks
- Run the engine to operating temperature. Monitor the radiator fan (if equipped) and ensure the cooling system operates normally.
- After a brief ride and full cool-down, re-check coolant level and top off if necessary.
Owner Notes for the 2023 GAS GAS TXT RACING 300
- Radiator fan: The TXT RACING 300 is fitted with a temperature-controlled fan; obstructed fins or a faulty fan can cause overheating, so check these components regularly.
- Hose condition: Inspect hoses for aging, bulges, or leaks at every coolant service. Replace as needed to protect your engine.
- Correct coolant type: Use only manufacturer-approved coolant; compatibility is key for trials bikes like the TXT 300 to prevent electrolysis and corrosion, especially in bikes with aluminum radiators.
- Capacity check: The TXT RACING 300's system is compact, so do not overfill. Too much coolant can cause overflow when the bike warms up.
Careful maintenance is the key to extending the life of your 2023 GAS GAS TXT RACING 300. Safe riding!
