How to Change the Coolant in a 2022 GAS GAS TXT RACING 280
Keeping your 2022 GAS GAS TXT RACING 280 performing at its peak requires regular maintenance, and changing the coolant is a critical step in protecting the engine. Below is a MotoSport-exclusive, step-by-step guide tailored to your model, ensuring safe and optimal results every time.
Why Coolant Maintenance Matters for Your TXT RACING 280
The TXT RACING 280 is a liquid-cooled, two-stroke trials bike built for exceptional agility and responsive power on technical terrain. Its lightweight aluminum frame and high-performance engine require consistent thermal management to prevent overheating and maximize reliability. Old or contaminated coolant loses its effectiveness, potentially resulting in poor engine performance or even damage over time. Coolant changes are especially vital if you ride in muddy or dusty environments, or after long periods of use.
Before You Begin
- Only work on the cooling system when the engine is completely cool–removing the radiator cap on a hot engine can cause severe scalding.
- Wear gloves and safety glasses to avoid skin and eye contact with coolant. Rinse immediately with water if you experience a splash.
- Dispose of used coolant responsibly, in accordance with local regulations.
- Refer to the owner's manual for any specific precautions regarding hoses, clamps, and coolant types recommended for your year and model.
Tools & Supplies
- Fresh coolant (choose a premixed, high-quality coolant compatible with aluminum radiators)
- Drain pan
- Funnel
- 8mm or 10mm wrench or socket (check your sump plug size)
- Pliers (for hose clamps, if needed)
- Rags and shop towels
Step-by-Step Coolant Change Guide
-
Locate the Radiator Cap and Drain Bolt:
The TXT RACING 280's radiator cap is typically found on the top of the right-side radiator. The drain bolt or screw can be found at the base of the water pump housing on the right-hand side of the engine. -
Remove Skid Plate or Plastics (if needed):
For easier access, you may need to remove the skid plate or side plastics with the appropriate tools. -
Drain the Old Coolant:
Place a drain pan under the water pump area. Slowly remove the radiator cap to release any residual pressure. Using your wrench, loosen the coolant drain bolt or the lowest hose clamp on the water pump and allow the coolant to fully drain.
Inspect the drained fluid for debris or discoloration, which could indicate contamination or internal wear. -
Flush with Distilled Water (Optional for Thorough Maintenance):
If the old coolant was especially dirty or you suspect contamination, reinstall the drain bolt and fill the system with distilled water. Run the engine briefly, then repeat the drain procedure. This extra step helps remove residue before adding new coolant. -
Replace and Tighten the Drain Bolt:
Ensure the drain bolt or hose is securely reattached. Use the recommended torque setting from the owner's manual to avoid stripping threads or cracking the housing. -
Add Fresh Coolant:
Slowly pour in new coolant via the radiator cap opening, using a funnel to avoid spills. Fill until the fluid just reaches the bottom of the radiator neck or as specified in the manual (refer to capacity recommendations). -
Bleed the Cooling System:
Tilt or gently rock the bike side to side to help purge air pockets. Squeeze the upper radiator hose to encourage trapped air to escape. Some models have a small bleeder screw on the cylinder head–if equipped, loosen it until a steady coolant flow is observed, then retighten. -
Check for Leaks:
With the radiator cap still off, start the engine and let it idle for 1-2 minutes. Top off the coolant if the level drops, then replace the cap securely. Watch all connections for leaks. - Reinstall Skid Plate or Plastics:
-
Final Inspection:
After a short ride, recheck the coolant level and top off if necessary.
Key Notes for TXT RACING 280 Owners
- The TXT RACING 280's cooling system capacity is relatively small, so maintaining the correct level is especially important for peak performance and engine longevity.
- Avoid mixing different coolant brands or types, as this can cause chemical reactions and potential clogging.
- Inspect hoses, clamps, and the radiator for wear, especially after tip-overs or heavy impacts common in trials competition.
Recommended Coolant Change Interval
For most trials riders, changing the coolant every 12 months or after any significant contamination event (such as a muddy competition) is recommended. Always observe coolant condition during preseason checks and after high-stress rides.
