Shop parts for your ride now!Changing the coolant in your 2015 GAS GAS TXT PRO 250 is a straightforward maintenance task designed to keep your trials bike running efficiently – especially important due to its high-precision, lightweight alloy motor. Regular coolant changes help prevent overheating and corrosion, crucial for maintaining peak engine performance and longevity. Below is a MotoSport-exclusive guide, specifically tailored for your TXT PRO 250.
What You Need
- New coolant compatible with lightweight alloy engines (avoid conventional automotive coolant)
- Distilled water for system flush, if needed
- Metric socket set (Allen and standard)
- Drain pan
- Funnel
- Protective gloves and eyewear
- Shop rags
Step-by-Step Coolant Change Instructions
- Let the bike cool completely before starting. Never attempt to open the radiator cap or coolant system while hot - severe scalding can occur due to pressurized fluid and steam.
-
Remove the seat and fuel tank for access. On the TXT PRO 250, first ensure the gas cap and fuel cock are closed. Disconnect the fuel line, unscrew the front tank mounting bolt, and lift away the tank.
This exposes the radiator assembly and hoses for service. - Locate the radiator drain plug, typically positioned at the base of the radiator or via the lower coolant hose. Place the drain pan beneath.
-
Unscrew the radiator cap gently to allow air flow, then remove the drain plug. Allow all coolant to drain thoroughly.
If the coolant is clouded, rusty, or contaminated, flush the system by refilling with distilled water, starting the bike briefly, and draining again. For deeper cleaning, a 50/50 mix of vinegar & distilled water works for safe scale removal. - Inspect hoses and radiator for cracks or leaks. Replace any compromised parts during this service.
- Reinstall the drain plug (use a new washer or O-ring if necessary for a leak-free seal).
- Slowly pour new coolant into the radiator through a funnel. Squeeze radiator hoses and gently rock the bike side to side – this helps remove trapped air bubbles.
-
With the radiator cap still off, start the bike and let it idle for about a minute. This circulates coolant and purges remaining air.
Quick blips of the throttle help move bubbles out. Top off coolant as needed once the system stabilizes. - Fill the overflow tank to the FULL line, replace the radiator cap, and reassemble the fuel tank and seat.
- Check for leaks and monitor coolant level after your first post-service ride, topping up as necessary.
Model-Specific Details & Notes
- The TXT PRO 250 uses coolant designed for high-performance alloy motors; never use regular automotive coolant to avoid internal corrosion.
- This engine is sensitive to overheating; keep an eye out for low coolant symptoms like excessive engine heat or coolant loss.
- Routine checks of the reservoir level are important, especially after your first ride post-change.
- Dispose of old coolant responsibly – never pour it down the drain. Collect and deliver it to a proper recycling center.
Important Safety Warnings
- Always work with the engine cold before service to avoid burns.
- Coolant is toxic to pets and wildlife – keep it secured and safely dispose of all waste.
- Wear gloves and protective eyewear when draining and refilling coolant.
