How to Change the Coolant in a 2023 GAS GAS TXT GP 300
Regular coolant changes are essential for maintaining peak performance and reliability in your 2023 GAS GAS TXT GP 300. This GP model is engineered for precise handling and exceptional power, making cooling system upkeep even more crucial for competitive riders and passionate enthusiasts. Below is MotoSport–exclusive guidance tailored to your bike.
What Makes the TXT GP 300 Unique

When to Change the Coolant
- Every 12 months or after heavy, muddy rides
- When coolant appears discolored or contaminated
- Before winter if low-temperature protection is required
Tools & Supplies Needed
- New coolant (refer to the manual for type and capacity)
- Container for old coolant
- 8mm or 10mm socket or wrench (check drain bolt size on your model)
- Phillips screwdriver
- Clean rags
- Funnel
- Gloves and eye protection
Step-by-Step Coolant Change Guide
- Ensure Engine is Cool—Always perform the coolant change on a cold engine to avoid burns.
- Remove the Seat and Tank Shrouds—This will give you access to the radiator cap.
- Remove the Radiator Cap—Twist the cap slowly to release any built-up pressure.
- Locate and Remove the Coolant Drain Bolt—It's usually found at the lower part of the water pump cover. Place your catch container below and fully remove the bolt to drain the coolant.
- Open the Bleeder Screw on the Cylinder Head–This is a key TXT GP touch: Crack the cylinder head bleeder to ensure all coolant and air are expelled.
- Flush (Optional)–If the old coolant is dirty, briefly fill the system with distilled water, reassemble, run the bike up to temperature, and drain again.
- Reinstall the Drain Bolt—Tighten it to factory torque specifications.
- Refill with New Coolant—Slowly pour coolant into the radiator filler neck (or the header tank, as equipped), filling until just below the lip.
- Vent Air (Bleed the System)—With the bleeder screw loosened, watch for a steady stream of coolant (no bubbles), then tighten the screw. Important for avoiding air pockets that could cause overheating.
- Replace the Radiator Cap and reinstall plastics and seat.
- Start the Engine and briefly let it idle. Re-check coolant level and top off if necessary.
- Dispose of Old Coolant Properly—Coolant is toxic and must not be poured down drains or onto the ground.
Model-Specific Notes for the 2023 TXT GP 300
- This model's bleeder screw is a special feature–always use it when refilling coolant to ensure complete system ventilation.
- Tight tolerances and compact frame make access easier for maintenance–watch for any overflow onto electrical components, as the layout is tight.
- The cooling system uses a modest volume for reduced weight; accurate fluid measurement matters for efficient cooling.
Pro Maintenance Tips
- Inspect radiator hoses for cracks or leaks during every coolant swap.
- Stick to manufacturer-spec coolant for freeze and corrosion protection year-round.
- Monitor the cooling fan function after changing coolant (if equipped).
- Always tighten all fasteners to spec—the GP's high vibration can back bolts out if not properly torqued.
With these steps and attention to detail, your 2023 GAS GAS TXT GP 300 will deliver reliable, cool-running performance whether you're training or competing.
