How to Change the Coolant in a 2011 GAS GAS EC200: MotoSport Proprietary Guide
Regularly changing the coolant in your 2011 GAS GAS EC200 is essential to keep your engine running efficiently and to prevent internal corrosion or overheating. While the process can be accomplished at home, attention to detail and basic mechanical care will ensure the best results. Here’s a MotoSport-exclusive step-by-step guide designed for your exact MMY dirt bike–no generic advice, just what you need for your EC200.
What Makes the 2011 GAS GAS EC200 Cooling System Unique?
- The water pump cover drain screw is specially positioned for direct drainage–always use it to expel all old coolant and avoid contaminating your bike or workspace.
- Engine aluminum components are particularly sensitive to poor coolant maintenance. Watch for whitish deposits or brown discoloration in the drained coolant, which indicates corrosion and signals a full flush is necessary.
- A new drain screw gasket is required every time you replace the coolant to preserve the system’s watertightness.
Tools & Items You’ll Need
- Clean catch basin for old coolant
- Correct premixed coolant suitable for aluminum engines (avoid tap water, use distilled if diluting concentrate)
- Socket or wrench for drain screw
- New drain screw gasket
- Gloves & rags for clean-up
Step-by-Step: Changing Your Coolant
- Cool Down Completely: Make sure the engine is cold before beginning. Place the bike upright on a stand.
- Remove Radiator Cap: Turn the radiator cap slowly to release built-up pressure. Always check and refill coolant when the engine is cold to get an accurate read.
- Drain Old Coolant:
- Place a container under the coolant drain screw (bottom of water pump cover).
- Carefully remove the drain screw and let all coolant escape. Avoid letting coolant touch the tires as it becomes extremely slippery.
- Inspect Coolant Appearance: Examine the drained coolant. If there are whitish spots, your system’s aluminum parts may be corroding. Brown tinge means ferrous parts are rusting. Either signals a need for a full flush before refill.
- Flush if Needed:
- For visible corrosion or contamination, flush the system by adding distilled water, running the engine briefly (with cap on), then draining again until water runs clear.
- Inspect Components: Before reassembly, look for damage, leaks, or missing gaskets.
- Reinstall Drain Screw & New Gasket: Replace the drain screw using a new gasket, tightening to manufacturer spec. This guarantees no leaks or loss of system pressure.
- Fill with Fresh Coolant: Pour new premixed coolant into the radiator up to just under the cap’s rubber seal.
- Bleed Air from the System:
- Start the engine briefly with the radiator cap off until you see surface bubbles stop and the coolant circulates. Top up as needed, then securely replace the radiator cap.
- Check for Leaks & Test Ride:
- Wipe away any spilled coolant. Start the engine and let it reach full temperature–monitor for stable operation and verify there are no leaks.
MotoSport Pro Tips for GAS GAS EC200 Owners
- Always use genuine or high-quality replacement gaskets and parts to preserve your EC200’s cooling efficiency and reliability.
- The compact design of the EC200 means that coolant access is straightforward, but clean-up is critical–protect your frame and tires from contact with coolant.
- Avoid overfilling. Fill to just under the cap’s lower seal, then bleed air–overfilling causes pressure issues and possible leaks during use.
- Check the system after your first ride for any minute leaks or unexpected drops in coolant level.
