How to Change the Coolant in a 2010 GAS GAS EC200
Changing the coolant in your 2010 GAS GAS EC200 is a crucial maintenance step for optimal engine performance and longevity. This step-by-step guide is tailored specifically for EC200 owners and highlights unique model considerations to ensure the process is smooth, safe & effective.
Why Change the Coolant?
Over time, coolant breaks down & loses its ability to transfer heat efficiently. Regular coolant replacement prevents overheating and protects vital engine components. For high-performance two-strokes like the EC200, fresh coolant is essential for sustained power and reliability.
Tools & Supplies Needed
- Fresh coolant compatible with aluminum engines (avoid silicate-rich automotive coolant)
- Distilled water (for flushing)
- Basic hand tools (screwdrivers, socket set, pliers)
- Drain pan or container
- Gloves & rags for cleanup
Step-by-Step Coolant Change Procedure
-
Prepare the Bike
Ensure the EC200 engine is completely cool. Place the bike upright on a stable surface or stand to access the radiator and lower hoses safely. -
Remove the Radiator Cap
Unscrew the radiator cap slowly to release any residual pressure in the system. -
Locate the Drain Point
On the EC200, the primary drain bolt is typically found on the lower right side of the engine (often at the water pump cover or engine case). Place your drain pan beneath this point. -
Drain the Old Coolant
Remove the drain bolt and allow all coolant to flow into the pan. Squeeze the lower radiator hose to help evacuate trapped coolant.
Optional but recommended: Disconnect the lower radiator hose at the engine for a more thorough drain. -
Flush the Cooling System
Reinstall the drain bolt and fill the radiator with distilled water. Replace the cap, start the engine, and let it idle for several minutes (do not rev hard). Shut it off, allow the engine to cool, and drain the system again. Repeat if the drained water is still discolored. -
Refill with New Coolant
Tighten the drain bolt to manufacturer specs. Fill the radiator slowly with your chosen coolant, periodically squeezing both upper and lower hoses to purge air pockets.
Leave a small amount of expansion space at the top. -
Bleed the System
With the radiator cap off, start the bike and let it idle. Watch for air bubbles escaping from the radiator neck as trapped air purges. Gently rock the bike side-to-side if needed. Once bubbles stop, top off coolant if needed and secure the radiator cap. -
Final Checks
Inspect all hose clamps and the drain bolt for leaks. After your next ride, check coolant level and add as needed.
GAS GAS EC200-Specific Tips & Notes
- The EC200's two-stroke engine is sensitive to overheating, especially in slow, technical terrain—use high-quality coolant formulated for dirt bike engines.
- Monitor the water pump seal for leaks after each coolant change. Seepage is often a sign the seal or bearing needs replacement—these are common wear items on this model.
- Inspect radiator hoses for cracks and softness. Originals may deteriorate after years and should be replaced to prevent failure during rides.
- If your EC200 has an overflow reservoir (rare in 2010 models), don't forget to drain and flush it as well.
- Follow proper disposal procedures for old coolant. Do not pour it on the ground or down home drains.
Maintenance Interval
For optimal protection, change the coolant every 12-18 months or after heavy riding seasons. If you ride mainly in harsh or muddy conditions, inspect or change more frequently.
Be Ready for Your Next Ride
Coolant changes are a simple way to protect your 2010 GAS GAS EC200 & keep it running at peak performance. Routine maintenance avoids costly repairs and lets you get the most from every ride—on or off the trail.
