How to Change the Coolant in a 2023 GAS GAS EC 250
Changing the coolant on your 2023 GAS GAS EC 250 is a straightforward job that ensures your engine stays at optimal temperature, prevents overheating, and extends your bike's life. This guide is tailored for MotoSport EC 250 owners and highlights model-specific tips – follow these steps to keep your ride in top performance.
Essential Tools & Supplies
- Drain pan
- Socket wrench (typically 8mm or 10mm for drain bolt)
- Flathead screwdriver
- Fresh coolant (compatible with aluminum engines)
- Clean rag
- Safety glasses/gloves
Preparation
- Ensure the bike is completely cool before starting. Never open the radiator cap when hot—serious burns can occur.
- Place the bike upright on a level surface using a stand.
- Remove any plastics or guards that obstruct radiator access.
Draining the Old Coolant
- Locate the radiator cap on the right side of the bike. Loosen, but do not fully remove, the cap to relieve any built-up pressure.
- Position a drain pan below the coolant drain bolt, found low on the right side of the engine case (often near the water pump).
- Remove the drain bolt with your socket wrench and allow the old coolant to fully drain.
- To speed the process, remove the radiator cap completely.
- If your model has a small bleeder screw on the cylinder head, open it to fully vent air and liquid.
Flushing (Recommended)
- If the old coolant appears dirty or contaminated, pour a small amount of distilled water into the radiator. Reinstall the drain bolt and radiator cap, gently tip the bike side to side, then drain again. Repeat until clear.
Refilling with Fresh Coolant
- Reinstall and tighten the drain bolt (consult your owner's manual for torque specification).
- Pour new coolant slowly into the radiator until it reaches the bottom of the filler neck. Avoid spills on painted surfaces.
- If equipped, briefly open the bleeder screw on the cylinder head to let trapped air escape. Once coolant seeps from the bleeder, tighten it securely.
- Replace and tighten the radiator cap.
Post-Service Steps
- Start the bike and let it idle until the engine reaches operating temperature. Cycle the throttle to help circulate coolant.
- Shut off the engine and allow to cool completely.
- Re-check the coolant level. Top off if necessary.
- Examine for leaks around the drain bolt, water pump, and radiator cap.
EC 250 Owner Notes
- The 2023 EC 250 uses a pressurized cooling system – always check hoses and clamps during maintenance.
- Use only coolant formulated for aluminum engines with corrosion inhibitors.
- If operating in freezing temperatures, ensure your coolant is rated for anticipated cold weather riding.
