How to Change the Coolant in a 2019 GAS GAS TXT Racing 300
Regular coolant changes are essential for maintaining peak performance and longevity of your 2019 GAS GAS TXT Racing 300. This model uses a liquid-cooled engine designed for the rigors of trial riding, making proper coolant maintenance crucial. Below is a step-by-step guide tailored specifically for this bike, with additional notes for TXT Racing owners.
Preparation – What You Need
- Special coolant for light alloy engines, rated for at least -30°C
- Socket set or wrenches
- Drain pan
- Rags and safety gloves
- Funnel
Before You Begin
- Always work with a completely cool engine to avoid burns and injuries. Never remove the radiator cap on a hot engine.
- Work in a well-ventilated space and keep coolant away from children and pets.
- Dispose of old coolant responsibly as it is hazardous to the environment.
Step-by-Step Coolant Change
-
Remove the Fuel Tank:
Remove the seat and the two bolts securing the fuel tank. Lift the front of the tank and slide it out from the frame. -
Locate the Radiator Cap & Drain Plug:
The TXT Racing 300 has dual side radiators. The cap is usually on the right radiator. The drain plug is typically located at the lower part of the water pump housing. -
Drain the Old Coolant:
Place the drain pan under the drain plug. Open the radiator cap to release system pressure, then remove the drain plug. Allow coolant to fully drain from both radiators. -
Flush (Optional):
If the old coolant is contaminated or discolored, flush the system with distilled water before proceeding. Replace the drain plug securely afterward. -
Refill With New Coolant:
Use the funnel to pour new coolant into the radiator until full. Allow air bubbles to escape by tilting the bike gently from side to side. Fill until the coolant is at the base of the radiator filler neck. -
Reinstall the Fuel Tank:
Slide the tank into place, ensuring the lines are correctly connected, then secure with bolts and replace the seat. -
Bleed Air & Check Levels:
Start the engine and let it idle. Watch the coolant level as air purges from the system. Shut off the engine, let it cool, and top off the radiator if needed. -
Final Inspection:
Check that all connections are secure and no leaks are present. Verify coolant level again once the engine is fully cool.
Notes Specific to the 2019 GAS GAS TXT Racing 300
- This model's cooling system is highly efficient but features narrow passages. Using the correct coolant is essential to prevent corrosion in the light alloy radiators and engine.
- Monitor the spark plug regularly, as improper coolant operation can alter engine performance and plug condition. The correct spark plug gap is 0.6–0.7 mm.
- Cooling system overflows occasionally after a hard trial session are normal, but persistent leaks or overflow indicate the need for a system check.
By following these proprietary steps, you ensure the best cooling performance for your 2019 GAS GAS TXT Racing 300—keeping your engine protected, your rides smooth, and your trial bike delivering peak results.
