How to Change the Coolant in a 2014 GAS GAS EC200
Changing the coolant in your 2014 GAS GAS EC200 is crucial for maintaining optimal engine temperature and long-term reliability. The EC200 uses a liquid-cooled 2-stroke engine, which relies on a well-maintained cooling system to avoid overheating, corrosion, and engine damage. This guide provides step-by-step instructions and model-specific tips for a thorough coolant change.
Tools – Materials Needed
- Socket set (for radiator drain bolt)
- Drain pan
- Fresh coolant (silicate-free recommended for motocross 2-strokes)
- Funnel
- Distilled water (for flushing, if necessary)
- Shop towels and gloves
Preparation Steps
- Ensure the dirt bike is cool. Never open the radiator cap while the engine is hot; scalding fluid and steam can spray out under pressure.
- Place the bike upright on a stand, preferably outdoors or over a washable surface.
How to Drain the Old Coolant
- Remove the seat and left shroud for easier radiator access.
- Loosen (but do not remove) the radiator cap to allow air flow during draining.
- Locate the engine coolant drain bolt at the base of the water pump on the lower right side of the engine case.
- Position your drain pan under the drain bolt and remove the bolt fully. Let old coolant completely drain out.
- Inspect the old coolant. If it appears dark, sludgy, or discolored, this can indicate contamination or corrosion inside the system—flush with distilled water until it runs clear before proceeding.
Refilling with Fresh Coolant
- Reinstall and secure the drain bolt. Tighten to manufacturer torque specs. Wipe away any drips.
- Remove the radiator cap entirely.
- With a funnel, pour your new coolant slowly into the radiator filler neck until fluid is visible near the top.
- On many GAS GAS models, there is a small bleeder screw located on the cylinder head or radiator. Loosen this screw briefly while filling to allow trapped air to escape; tighten once coolant seeps out, then top off the radiator again.
- Reinstall the radiator cap securely.
Final Checks – Startup
- Start the engine and let it idle several minutes with the bike upright. Watch for leaks near the drain bolt, water pump, and radiator hoses.
- As the thermostat opens, you may see air bubbles vent into the overflow. Shut off the engine and let cool.
- Once cool, remove the radiator cap again and top off if necessary. Coolant level should be just below the bottom of the filler neck.
Model-Specific Notes for 2014 GAS GAS EC200 Owners
- The EC200 shares its cooling system design with other EC 2-strokes, but check for a cylinder-head bleeder screw to ensure proper air removal, as air pockets can cause overheating.
- For best results, use a high-quality, silicate-free motorcycle coolant engineered for aluminum radiators. Avoid automotive coolants with silicates or phosphates, as these can accelerate wear in motorcycle water pumps and radiators.
- Inspect the condition of your radiator cap and hoses; excessive pressure loss or cracking can affect cooling performance.
- Recommended coolant change interval is at least once per year, or after any contamination event.
- If you ride in muddy or clay-heavy environments, wash radiator fins gently to maintain airflow. Blocked fins reduce cooling efficiency and may lead to overheating.
After Service
- Dispose of old coolant responsibly at your local hazardous waste facility–do not pour down drains or onto the ground due to toxicity.
- Keep a close eye on the coolant level over the next several rides, topping off as air fully purges from the system.
Routine coolant maintenance on the 2014 GAS GAS EC200 keeps your engine protected from overheating and corrosion, supporting longer life and better performance across every MotoSport adventure.
