How to Change the Coolant in a 2014 GAS GAS EC250E
Maintaining the cooling system on your 2014 GAS GAS EC250E ensures peak performance and long-term engine health, especially during aggressive off-road rides. Changing the coolant regularly – at least once per year or according to heavy-use intervals – is essential for your dirt bike’s reliability. Follow this MotoSport-proprietary guide tailored to your MMY (Make/Model/Year) dirt bike, including model-specific tips every GAS GAS owner should know.
What You’ll Need
- Drain pan
- New coolant (GRO GCC 30% is recommended for extended protection down to -18°C)
- Distilled water (if mixing)
- Socket and wrench set
- Light-duty cleaning brush
- Protective gloves
- Rags or paper towels
Step-by-Step Coolant Change Instructions
-
Let the Engine Cool:
Make sure your bike is fully cooled before beginning. Hot coolant and pressurized systems can cause serious burns. -
Remove Both Radiator Shrouds:
For best access, remove both side shrouds using the appropriate socket or Allen wrench. This exposes the radiator cap and drain bolt. -
Locate the Radiator Cap & Drain Bolt:
The EC250E features a radiator cap mounted high on the left radiator. The lowest bolt on the water pump cover (located at the right engine side) also serves as the drain plug for the coolant. -
Drain the System:
Place your drain pan under the water pump cover. Remove the radiator cap to break vacuum and speed draining. Then remove the drain bolt. Allow all coolant to fully drain, tilting the bike gently side to side to evacuate trapped fluid. -
Inspect & Clean:
Inspect the coolant for contaminants or corrosion. Clean around the drain bolt area with a soft brush. Replace the sealing washer on the drain bolt if worn or damaged. -
Reinstall the Drain Bolt:
Tightly fasten the drain bolt (use manufacturer-spec torque if available). -
Mix & Add New Coolant:
Use a pre-mixed, motorcycle-specific coolant compatible with aluminum (GRO GCC 30%, or equivalent). If mixing manually, blend with distilled water at the recommended ratio – 30% coolant or as indicated on the coolant container.
Pour slowly into the radiator until full. -
Bleed the System:
With the radiator cap off, start the engine and let it idle. Watch for air bubbles as air purges out. When bubbling subsides and the coolant drops, top off to just below the cap. Monitor temperature – the thermostat should open, drawing more coolant in. Stop the engine and reinstall the cap carefully. -
Check for Leaks & Final Level:
Inspect all sealing areas for leaks. After your first short ride, let the bike cool again and recheck coolant level, topping off if necessary.
Model-Specific Notes for the 2014 GAS GAS EC250E
- Coolant Type: The recommended coolant for your EC250E is GRO GCC 30% for optimal corrosion resistance and freeze protection (–18°C typical protection).
- Radiator Capacity: The system typically holds just under 1 liter. Overfilling may cause overflow when heated; fill to just below the lower edge of the radiator neck.
- Sealing Washers: Replace the drain bolt washer any time you notice seepage or at every major coolant service for best sealing.
- Bleeding Air: The EC250E’s two-stroke engine is sensitive to excess heat – trapped air can cause rapid overheating. Always idle and gently rev after refill to purge air fully.
- Service Interval: Check coolant clarity and proper level every 15–20 operating hours or after deep water crossings. Change the coolant at least annually for best results.
Final Checkpoint
- After installation, monitor your temperature gauge or warning light closely for the first few rides to confirm effective cooling.
- Replace coolant more frequently if riding sand, mud, or high load – the EC250E thrives when kept cool and clean.
