How to Change the Coolant in a 2019 GAS GAS EC200
Changing the coolant in your 2019 GAS GAS EC200 is a vital part of routine maintenance, ensuring optimal engine performance and longevity. While this task is straightforward for most dirt bike owners, the EC200 has a few unique considerations that set it apart from similar two-stroke machines. Below is a MotoSport-exclusive step-by-step guide for a precise and clean coolant change, as well as tips you need to know for your specific model.
Supplies and Preparation
- Fresh coolant compatible with aluminum motorcycle radiators (avoid mixtures with plain water only for best anti-corrosion and boil-over protection)
- Basic metric hand tools (socket or Allen set, screwdrivers)
- Drain pan
- Clean rags
- Gloves and safety glasses
Step-by-Step Coolant Change Process
-
Allow the Engine to Cool
Never attempt to open a radiator cap or drain coolant on a hot engine. Ensure your GAS GAS EC200 has cooled down completely to avoid burns or injury.
Pro tip: Putting the bike on a center stand or secure lift keeps it upright and stable through the whole procedure.
-
Remove the Radiator Cap
Locate and slowly remove the radiator cap. This is typically found on the right side, above the cylinder head. Turn it slowly to the first stop to release system pressure, then remove fully.
-
Drain the Old Coolant
Find the coolant drain bolt–usually on the water pump cover, lower right side–and prepare your drain pan beneath it. Use the correct socket or Allen tool to loosen the bolt and let all coolant flow out.
Also remove or loosen the radiator cap if you have not already, to allow for a steady drain.
Inspect the coolant as it drains—milky or rusty coolant can be a sign of leaks or engine issues.
-
Inspect and Reinstall Drain Bolt
Wipe down the bolt and check the sealing washer or O-ring. Replace if damaged. Reinstall and torque the drain bolt firmly–do not overtighten. Proper torque for the EC200 water pump cover bolts is typically in the 8–10 Nm range. -
Flush the Cooling System (Optional, but Recommended)
For maximum system cleanliness, you can flush with distilled water before adding new coolant. Fill the radiator with water, run the bike briefly, and drain again. Repeat until water runs clear. -
Refill with Fresh Coolant
Slowly fill the radiator with your chosen coolant, up to just below the neck. For cold climates, use a 60:40 coolant to water mix. Never use pure water in racing or extended off-road use.
Bleed air from the system: The EC200 has a small bleed port/bolt on the cylinder head or near the thermostat housing. Crack this open gently while filling to allow trapped air to escape until fluid seeps out, then snug it back down. -
Check Coolant Level and Cap
Once the bike is full and bled, reinstall the radiator cap. Start the engine and idle for a few minutes, then shut off. Allow it to cool; recheck coolant level and top off if necessary.
-
Check for Leaks and Finish
Look over radiator hoses, the drain bolt area, and the cap. Repair any leaks. Dispose of all old coolant responsibly.
Notable Tips for 2019 GAS GAS EC200 Owners
- Radiator Design: The EC200 uses robust aluminum radiators and a high-flow pump designed for enduro conditions. Regular flushing of mud and debris from the radiator fins enhances cooling efficiency, especially if you ride in wet or muddy environments.
- Bleed Port Awareness: This model often has a dedicated bleed port on top of the cylinder—an important detail for getting trapped air out of the cooling system. Ignoring this step can cause engine overheating or coolant loss.
- Routine Inspection: Check radiator cap condition regularly. Replace if you notice worn rubber seals, as low system pressure can lead to overheating.
- Coolant Type: For the EC200, always use a performance motorcycle coolant designed for aluminum components; avoid car antifreeze products that contain silicates which can harm water pump seals.
- Maintenance Interval: GAS GAS recommends changing the coolant at least once a year, or more often if riding aggressively or in extreme conditions.
