How to Change the Coolant in a 2021 GAS GAS TXT GP 250
Maintaining the cooling system on your 2021 GAS GAS TXT GP 250 is essential for engine longevity and consistent performance, especially if you ride in demanding conditions. Follow this step-by-step, model-specific guide made just for MotoSport riders.
Preparation
- Ensure the engine is completely cool before starting to avoid injury from hot coolant or pressurized steam.
- Place your TXT GP 250 on a stable, level stand.
- Gather the necessary items: a fresh bottle of recommended coolant, a clean funnel, a drain pan, gloves, and basic hand tools.
1. Access the Radiator and Coolant System
- Remove the seat and tank shrouds as needed for clear access to the radiator cap and hoses.
- The radiator cap is typically located beneath the fuel tank on the right side. Gently remove the cap to relieve any remaining pressure.
2. Draining the Old Coolant
- Place a drain pan under the lowest point of the cooling system. For the 2021 TXT GP 250, this is usually at a lower hose connection on the radiator or at a drain bolt on the water pump case.
- Loosen the hose clamp or unscrew the drain bolt, letting all the coolant drain into your pan. Take care not to spill coolant on tires or painted surfaces.
- Once drained, inspect the old coolant for contaminants. Flush with distilled water if the coolant looks rusty or dirty.
3. Refilling with New Coolant
- Tighten the hose clamp or re-install the drain bolt securely.
- Using a funnel, slowly fill the radiator with high-quality, motocross-approved coolant until it reaches the base of the filler neck. For trials bikes like the TXT GP 250, always use a non-silicate formula to protect magnesium engine components.
- Gently tip the bike side to side several times to help release trapped air.
- Fill the radiator once more if needed; do not overfill as you need space for expansion.
4. Bleeding and Checking the System
- Start the engine and let it idle with the radiator cap off, monitoring coolant level. Top up if needed as any trapped air is purged.
- Once no more bubbles rise and the level stabilizes, replace the radiator cap securely.
5. Finishing Up
- Check all hose clamps and fittings for leaks.
- Reinstall bodywork and seat.
- Properly dispose of the old coolant at a recycling center.
- After the first ride, recheck the coolant level once the bike is cool and top off if necessary.
Special Notes for the 2021 GAS GAS TXT GP 250 Owner
- This model uses a high-revving two-stroke engineoverheating can cause rapid power loss. Routine coolant checks are especially important if riding trials courses with lots of slow-speed sections.
- Always avoid mixing coolant types, and go for a premix that protects magnesium and aluminum internals common on the TXT GP 250.
- If your bike shows signs of overheating or the fan runs excessively, inspect the radiator closely for blockages or fin damage and ensure the coolant system is fully bled of air.
Changing your coolant is a key part of keeping your 2021 GAS GAS TXT GP 250 race-ready. Keep up on maintenance for reliable performance in every ride.
