How to Change the Coolant in a 2022 GAS GAS EC 250: Step-by-Step Guide
Regular coolant changing keeps your 2022 GAS GAS EC 250 running cool under pressure – and prolongs engine life by preventing corrosion and overheating. Here's a proprietary MotoSport instruction guide designed for your exact bike.
What Owners of the 2022 GAS GAS EC 250 Should Know
- Factory Radiators: The 2022 EC 250 is fitted with lightweight, high-flow radiators specific to this model. Overfilling or using water instead of premium moto coolant can reduce efficiency and cause excess pressure or corrosion.
- Bleed Screw Placement: This model uses a cylinder head bleeder screw for proper air removal from the system. It is vital to use this as trapped air easily causes overheating.
- Sensitive Plastics: Take care around the red plastics—exposure to harsh chemicals may cause discoloration.
Required Supplies
- Fresh coolant (engineered for 2-stroke dirt bikes)
- Basic metric hand tools (sockets, wrenches)
- Drain pan
- Shop rags
- Plastic-safe funnel
- Safety gloves
Step-by-Step Coolant Change Process
-
Let Your Engine Cool Completely
Never attempt to open the radiator or other cooling system parts when the bike is hot or under pressure – this can lead to burns and injury. -
Access the Radiator Cap and Drain Bolt
Remove the seat and any plastics around the radiators for easy access. Twist off the radiator cap (counterclockwise) to allow air in for easy draining. -
Locate the Coolant Drain Bolt
On the lower portion of the water pump cover (right side of the engine), find and remove the coolant drain bolt. Have your drain pan ready underneath. -
Drain the Old Coolant
Allow all coolant to drain out. For a fuller flush on neglected systems, flush the radiators with distilled water, then drain again. -
Reinstall and Torque the Drain Bolt
Inspect and clean the drain bolt, replace the sealing washer if worn, and reinstall. Tighten carefully to the specified torque. -
Refill With Fresh Coolant
Slowly add new coolant into the radiator filler. Fill until nearly full. -
Use the Cylinder Head Bleed Screw
Loosen the small bleed screw on top of the cylinder head until you see coolant (without air bubbles) trickle out. Tighten it again securely. -
Top Off and Recheck
Add coolant again if the level dropped. The fluid should be just below the radiator neck base. -
Run the Engine Briefly
Start and idle the bike with the radiator cap off to purge air. Watch the level – if it drops, top off as needed. Shut down, let cool, and check one more time. -
Replace the Radiator Cap and Reassemble
Secure the cap, reinstall plastics and seat.
Final Checks and Recommendations
- Inspect the radiator and hose connections for any sign of leakage.
- Check coolant level after your first ride – trapped air may escape and lower the level slightly.
- Dispose of old coolant responsibly at approved recycling centers; never pour it onto the ground.
Maintaining proper coolant with this process protects your EC 250's high-performance engine, ensuring cool running and maximum reliability on every MotoSport adventure.
