How to Change the Coolant in a 2007 GAS GAS EC200: A MotoSport Guide
Regularly changing the coolant in your 2007 GAS GAS EC200 is essential for maintaining optimal engine temperature, preventing corrosion, and preserving performance. Follow this MotoSport-exclusive guide for the correct procedure and important tips unique to your dirt bike.
Tools & Supplies You'll Need
- Fresh coolant (use high-quality motorcycle-specific coolantnot automotive coolant)
- Drain pan
- 8mm or 10mm wrench (check your EC200 drain bolt size)
- Funnel
- Phillips screwdriver
- Clean water or distilled water (for rinsing, if required)
- Safety gloves & rags
Step-by-Step Coolant Change Instructions
- Let the bike cool completely. Hot coolant can cause serious burns.
- Remove the seat and side panels to access the radiator cap. The 2007 EC200 layout should make this straightforwarduse a Phillips screwdriver.
- Open the radiator cap slowly. This releases any residual pressure.
- Locate the coolant drain bolt. For the EC200, look at the bottom of the water pump cover or the cylinder sideusually an 8mm or 10mm bolt. Place the drain pan beneath it.
- Remove the drain bolt. Allow all coolant to fully drain.
- If coolant appears dirty or contaminated (as some riders have noted, discoloration and residue can occur in older two-strokes), rinse the system with clean distilled water. Reinstall the drain bolt, fill the radiator with water, run the engine briefly, and then drain again until clear.
- Inspect the old coolant. Black sand-like particles are sometimes reported on older GAS GAS engines. These can indicate early corrosion or gasket degradation–if present, flush thoroughly and monitor in the future.
- Reinstall the drain bolt and tighten securely.
- Fill the radiator with fresh coolant. Use a funnel and fill just below the neck. The GAS GAS EC200 cooling system typically takes approximately 1.2 liters, but always check the radiator's fill level.
- Rock the bike side to side to help release trapped air bubbles.
- Start the engine and let it idle. With the radiator cap off, watch for bubbling (trapped air escaping) and top up the level as needed.
- Replace the radiator cap. Confirm it's seated securely.
- Wipe up any spills and reinstall seat and panels.
GAS GAS EC200-Specific Notes
- This model is known for its high-revving two-stroke engine–consistent coolant changes are vital for longevity and preventing overheating, especially under heavy use or racing conditions.
- Use a 30% glycol-based motorcycle coolant designed for aluminum engines to protect against freezing, boiling, and internal corrosion.
- Some owners have reported dark or contaminated coolant on their first change. This can come from prior neglect or gasket residue. If you notice persistent residue, inspect hoses and consider engine seals at your next service interval.
When to Change the Coolant
- Replace coolant every 1–2 years or at the beginning of each major riding season for best performance. Change more frequently if riding hard in hot climates or after any overheating incident.
Final Tip
Avoid mixing coolant brands or colors unless the label says they are compatible. Always dispose of old coolant responsiblyit is toxic to animals and the environment.
