Maintaining the cooling system in your 2013 GAS GAS EC250 is critical for optimal engine health and consistent off-road performance. Coolant should be changed periodically to ensure the engine operates at its best and to maximize the lifespan of your dirt bike’s components. Below is a detailed, MotoSport-exclusive guide for safely and effectively changing the coolant in your EC250.

What You’ll Need

  • Fresh coolant (GRO GCC 30% Long time recommended; premixed or mix with distilled water to a 50/50 ratio)
  • Distilled water (if applicable) – never use tap water, as it can cause mineral build-up in the radiator
  • Drain pan
  • Flat-head screwdriver or socket set (for drain and radiator bolts)
  • Protective gloves and goggles
  • Shop towels or rags

Instructions

  1. Preparation
    • Allow the engine to cool completely to prevent burns. Never remove the radiator cap on a hot engine – pressurized hot coolant can result in serious injury.
    • Place your bike on a stable stand and remove any bodywork or panels as needed to access the radiator and drain bolt.
  2. Draining the Old Coolant
    • Locate the radiator cap and drain bolt (usually at the bottom of the water pump cover or lower radiator hose).
    • Place a drain pan beneath the bike’s drain bolt.
    • Remove the radiator cap to release pressure.
    • Carefully unscrew the drain bolt and allow all coolant to drain out. Tilt the bike gently side-to-side to ensure full drainage.
    • Inspect the removed coolant for contamination, which might indicate a need for a system flush or further inspection.
  3. Flushing the System (Optional but Recommended)
    • If desired, briefly fill the radiator with distilled water and drain again to flush out any residual coolant or debris. Repeat until the water runs clear.
  4. Refilling with New Coolant
    • Install a new sealing washer on the drain bolt and tighten to manufacturer torque spec.
    • Pour in the fresh, recommended coolant (GRO GCC 30% Long time, or premixed equivalent) up to the radiator filler neck. If mixing, use only distilled water.
  5. "Burping" the Radiator
    • With the radiator cap still off, start the engine and let it idle for several minutes. Occasionally gently blip the throttle to help release air bubbles trapped in the system.
    • Watch for the coolant level to drop as air escapes. Top off as needed until stable.
    • Replace the radiator cap.
  6. Final Steps
    • Check all connections for leaks.
    • Reinstall any bodywork or panels that were removed.
    • Dispose of used coolant properly at an authorized recycling center or auto parts store.
    • After your next short ride, recheck the coolant level and inspect again for leaks.

Model-Specific Tips for the 2013 GAS GAS EC250

  • The recommended coolant is GRO GCC 30% Long time, which is specifically formulated for long life and cold protection down to -18°C – using the correct type helps prevent corrosion inside your magnesium engine components and radiators.
  • Always use a coolant that contains rust and corrosion inhibitors to protect the EC250's aluminum and magnesium parts. Failure to do so can result in internal radiator corrosion and potential clogging of cooling hoses.
  • Check your owner’s manual for any unique torque settings for the drain bolt and cap on the EC250.
  • If you notice persistent low coolant levels after the change, investigate for possible leaks in radiator hoses or gaskets.
  • Routine coolant replacement should be done every two years, or more frequently if riding in exceptionally hot or cold conditions.

Why Timely Coolant Changes Matter

Neglecting to change coolant leads to corrosion, overheating, and possible engine damage. The 2013 GAS GAS EC250's high-performance 2-stroke engine is especially sensitive to temperature variations, making scheduled coolant changes essential for performance and reliability.
