How to Change the Coolant in a 2022 GAS GAS EC 300: Complete MotoSport Guide
Regularly changing the coolant on your 2022 GAS GAS EC 300 is critical to keep your engine running at optimal temperatures, ensure long-term reliability, and prevent overheating—especially under tough off-road conditions that push every component to its limit. The EC 300's advanced two-stroke liquid-cooled engine relies on a well-maintained cooling system to deliver peak performance through the roughest rides.
What Makes Coolant Changes Important on the GAS GAS EC 300?
- Two-stroke engines run hotter than four-strokes, making fresh coolant paramount for heat management.
- Riding in mud, extreme heat, or technical terrain can speed up coolant degradation.
- The 2022 EC 300 features a robust radiator and cylinder-head bleeder screw, helping to eliminate trapped air and maximize cooling efficiency.
Step-by-Step: Changing the Coolant on the 2022 GAS GAS EC 300
- Prep the Bike
- Ensure the engine is cool to the touch for safety.
- Place the bike on a level stand and remove the radiator shrouds for easier access if necessary.
- Drain the Old Coolant
- Locate the coolant drain bolt on the water pump cover or lower radiator hose–this is typically on the right-hand side of the engine.
- Place a drain pan beneath, and remove the bolt or hose to let coolant completely drain.
- Remove the radiator cap to expedite draining.
- Flush If Needed
- If the old coolant is contaminated or your rides have been especially muddy, pour distilled water into the radiator, reinstall the drain bolt, run the bike briefly, and then drain again.
- Reinstall the Drain Bolt
- Clean the bolt threads and sealing surfaces; replace the sealing washer if it's worn.
- Tighten the drain bolt to manufacturer specifications to prevent leaks.
- Fill with Fresh Coolant
- Use a high-quality, motorcycle-specific coolant with adequate antifreeze and corrosion inhibitors, as recommended by the manufacturer.
- Fill the radiator through the cap opening until coolant reaches just below the neck.
- On the EC 300, locate the small bleeder screw on the top of the cylinder head. Loosen it until air can escape and only coolant flows out, then retighten–this step is crucial to eliminate air pockets that can cause overheating.
- Check and Top Off
- Briefly run the engine with the radiator cap off to help burp any remaining air bubbles. Top off the coolant as needed.
- Reinstall the radiator cap securely.
- Inspect for Leaks & Reassemble
- Check all connections, the drain bolt, and around the radiator cap for leaks.
- Reinstall radiator shrouds and any removed parts.
What Owners of the 2022 GAS GAS EC 300 Should Know
- Bleeding the cooling system via the cylinder head screw is unique to this model and essential for optimal coolant function.
- The EC 300 uses a closed, pressurized radiator system that holds about 0.9 liters of coolant.
- Always use coolant approved for aluminum engines to prevent corrosion and ensure maximum efficiency.
- Check coolant level often, especially after hard riding or crashes, as even minor leaks can seriously impact engine health.
Recommended Maintenance Intervals
- Inspect coolant before every ride.
- Replace coolant at least once a year or every 15-20 hours of aggressive riding for maximum protection.
