How to Change the Coolant in a 2014 GAS GAS EC250
Regular coolant changes are key to keeping your 2014 GAS GAS EC250 running cool – especially in demanding off-road conditions. Below is a step-by-step guide tailored specifically for your EC250, along with owner tips unique to this model.
Tools & Supplies Needed
- Fresh coolant (consult owner manual for type, ideally a premium ethylene glycol premix suitable for aluminum engines)
- Soft or distilled water (do not use tap water to avoid mineral buildup)
- Drain pan
- Socket/ratchet set
- New copper washer for drain screw
- Shop towels
- Protective gloves & eyewear
Instructions
- Let the engine cool: Never open the radiator cap when hot. Wait until the engine is completely cool to avoid burns.
- Access the radiator: Remove the shrouds or any covers if they obstruct access to the radiator cap.
- Remove the radiator cap: Slowly twist the cap to release pressure.
- Locate and remove the drain screw: Position a drain pan under the water pump cover on the right side. The drain screw is typically at the lowest point of the pump cover. Slowly unscrew it (recommended torque for reinstallation is 9 Nm) and allow all old coolant to drain completely.
Tip: Replace the copper washer on the drain screw when reinstalling to avoid leaks. - Flush the system (optional but recommended): For best results, flush the cooling system with distilled water to remove any old coolant or debris. Reinstall drain screw and washer, fill with distilled water, run the engine briefly with the radiator cap off, then drain again.
- Reinstall drain screw: Tighten to the specified torque with a new washer.
- Refill with coolant: Pour fresh coolant into the radiator until it reaches the bottom of the filler neck.
- Bleed air: Lightly tap radiator hoses and gently rock the bike side-to-side to dislodge trapped air. Add more coolant if the level drops.
- Install radiator cap: Secure the cap once coolant is at the proper level.
- Warm up the engine: Run the engine until warm, then shut it off and let cool. Double-check coolant level and top up if necessary.
- Inspect for leaks: Check for leaks around the drain screw and hoses. Make sure the system is sealed.
Key Notes for 2014 GAS GAS EC250 Owners
- Inspect every 30 hours, replace every 60 hours: This is a more aggressive interval than some brands, reflecting the EC250's performance design.
- Aluminum cooling system: Always use coolant suitable for aluminum engines and soft/distilled water. Improper fluid may cause corrosion or clog internal passages.
- Check for hose leaks or worn seals: Dirt, vibration, and age affect hoses and clamps. Inspect for damage or leaks each change.
- Coolant color: Examine drained coolant for contamination—milky, brown, or sludgy fluids indicate possible corrosion or system issues that should be addressed.
- Avoid tire contamination: Spilled coolant on tires may cause a loss of traction, leading to accidents.
EC250 Extra Tips
- Coolant capacity: The EC250 has a compact but high-efficiency radiator setup. Overfilling can cause spillage, underfilling risks overheating. Fill carefully.
- Drain bolt torque: Overtightening can strip threads, especially in softer engine cases. Always use a torque wrench at 9 Nm for reinstallation.
With these steps, your 2014 GAS GAS EC250 will be ready to tackle trails and tracks—with cooling performance optimized for reliability every ride.
