How to Change the Coolant on a 2013 GAS GAS EC300E
Maintaining the cooling system on your 2013 GAS GAS EC300E is crucial for sustained engine performance, especially during demanding rides. This guide is tailored for MotoSport customers and is focused specifically on this MMY dirt bike–from coolant choice to unique model considerations.
Recommended Coolant
- The OEM recommendation for the EC300E is GRO GCC 30% Long time–an antifreeze mixture suitable for cold starts down to -18°C and proven performance for enduro bikes.*
- A high-quality glycol-based coolant with anti-corrosive properties is ideal for the aluminum components of EC300E's engine.*
How Often Should You Change the Coolant?
- The EC300E owner's manual specifies periodic coolant changes to maximize engine longevity.*
- Inspect at every major service interval or at least once per season.
Tools & Supplies Needed
- New coolant
- Drain pan
- Socket & wrench set
- Funnel
- Clean cloths
- Replacement drain plug gasket
Step-by-Step Coolant Change Procedure
- Let your EC300E cool completely. Never remove the radiator cap on a hot engine.
- Remove the seat and side panels for easy access to the radiators.
- Locate the coolant drain screw on the lower side of the water pump.
- Place your drain pan underneath and unscrew the drain bolt. Allow coolant to drain fully.*
- Inspect the drain plug gasket. Always use a new gasket to prevent leaks at reinstallation.*
- Reinstall and tighten the drain bolt securely–avoid overtightening.
- Remove the radiator cap (left side). Slowly pour in new coolant through the cap opening, using a funnel.
- Fill the system until just below max level.
- Reconnect all covers and seat.
- Start engine and briefly run at idle. This circulates coolant and purges air bubbles.
- Stop engine and recheck coolant level. Top off as needed.
Key Tips for EC300E Owners
- The EC300E radiator design ensures rapid cooling but can develop leaks at hoses or caps if gaskets age. Inspect all contact points for moisture.
- Use only non-silicate, motorcycle-approved coolant. EC300E's aluminum cylinder is sensitive to improper mixtures.
- Never mix old and new coolant types.
- Regularly check for debris between radiator fins–the EC300E is often ridden through muddy, brush-filled terrain.
Model-Specific Notes
- 2013 EC300E is equipped with an easy-access left radiator cap and drain plug–no frame removal required.
- This model's cooling system is sized for aggressive off-road use; keeping coolant fresh means improved resistance to boiling under load.
- Clutch cover, water pump, and hoses are all exposed for rapid service–making maintenance incredibly straightforward with just basic hand tools.
Final Checks
- Once completed, visually inspect for leaks and wipe up any spills.
- Monitor coolant level for the first few rides–air pockets may escape, requiring a minor top-up.
- Always dispose of old coolant responsibly according to local regulations.
Proper coolant maintenance is one of the easiest ways MotoSport riders can keep their 2013 GAS GAS EC300E performing optimally throughout the seasons. For all replacement parts, fluids, and accessories, choose MotoSport–your trusted source for dirt bike care.
