How to Change the Coolant in a 2024 GAS GAS EX 250F
Maintaining a healthy cooling system is critical for peak performance and long engine life on your 2024 GAS GAS EX 250F. Coolant not only manages engine temperature but also prevents corrosion and protects internal passages on this 250cc four-stroke enduro machine. This unique model uses advanced radiator design and compact layout – keeping it light and nimble for tight trails. All procedures here are tailored for the GAS GAS EX 250F platform.
Preparation and Tools
- Fresh coolant meeting OEM specifications (ethylene glycol-based, silicate-free)
- Socket set, ideally with extensions (most drain bolts are 8mm or 10mm)
- Clean funnel and catch pan
- Safety gloves and eyewear
- Soft cloths for cleanup
Step-by-Step Coolant Change for GAS GAS EX 250F
- Ensure Engine Is Cool: If the bike was ridden recently, let it cool to avoid burns from hot coolant or engine parts. Never open the radiator cap while the system is hot.
- Remove Skid Plate or Shrouds (if equipped): For easier access to the radiator drain bolt and lower hoses, unfasten any plastic panels that obstruct your workspace.
- Position Your Catch Pan: Place the pan under the coolant drain (typically at the lowest point of one radiator or water pump cover on the EX 250F).
- Open Radiator Cap: Twist the cap on the left radiator slowly to vent the system. This allows quicker and more complete drainage.
- Undo Drain Bolt: Using your socket, carefully loosen the coolant drain. On the EX 250F, this is located at the water pump cover. Let coolant flow completely – tipping the bike slightly can help. Inspect the drained coolant for unusual debris or discoloration.
- Flush System (Optional but Recommended): For thorough cleaning, flush with distilled water until clear. Reinstall drain bolt and gently torque to factory spec.
- Refill with Coolant: Pour in new coolant to the recommended level. On the EX 250F, fill until fluid just covers the radiator core fins when viewed through the cap opening. Use a funnel to prevent spills & air pockets. Replace cap securely.
- Start Engine and Bleed Air: With the rad cap on, start engine and let idle. Briefly rev and watch for bubbling or fluid drop. Shut off, let cool, then recheck and top off coolant if necessary.
- Dispose of Old Coolant Properly: Used coolant is toxic – follow local regulations for disposal. Wipe stray spills to avoid damage to plastics or discomfort.
- Final Inspection: Confirm that all bolts, caps, and panels are secure before riding. Check for leaks around hoses and water pump cover.
GAS GAS EX 250F Owner Notes
- The EX 250F uses a compact twin-radiator system. Always check both sides for even fill.
- This model features tight bodywork and closed water pump housing; take care not to over-tighten drain bolts.
- Replace coolant every 1-2 years or sooner for competition use, as heat cycles degrade protections.
- If you notice overheating or rapid coolant loss, inspect hoses and pumps – EX 250F enduro models are sensitive to dirt intrusion at connectors.
- Rad cap pressure ratings impact engine temp; use only OEM-specified components.
Safety Tips
- If coolant gets into eyes or on skin, rinse thoroughly and consult a medical professional.
- Change any clothing exposed to coolant promptly.
- Work in a well-ventilated area and keep coolant away from children and pets.
Regular coolant service keeps your 2024 GAS GAS EX 250F running cool, protecting your investment – and the thrill of every ride.
