How to Change the Coolant in a 2006 GAS GAS EC200
Maintaining a proper cooling system is essential for the longevity and performance of your 2006 GAS GAS EC200. Regularly changing the coolant reduces the risk of overheating, corrosion, and engine damage. This guide walks you through every step to easily and effectively change your dirt bike's coolant.
What You Need
- Fresh motorcycle-compatible coolant (do not mix brands or types for best results)
- Distilled water (if using concentrate, not needed for premix)
- Rags or shop towels
- Catch pan or container for old coolant
- Basic hand tools (ratchet, sockets, screwdrivers)
- Protective gloves
Step 1 – Preparation
- Make sure the bike is cooled down completely. Never work on a hot engine, as the cooling system is pressurized and hot liquid can cause burns.
- Place the bike on a stand or level surface for stability and access.
Step 2 – Access and Drain Old Coolant
- Remove side panels and other plastics as needed to access the radiator cap and drain bolt.
- Open the radiator cap to release any built-up pressure.
- Locate the coolant drain bolt, typically found at the lowest point of the water pump cover.
- Place your catch pan under the drain bolt and remove the bolt. Allow all coolant to fully drain out.
Step 3 – Inspect and Clean
- Check the drain bolt washer. Replace it if worn or damaged to prevent leaks.
- Inspect visible radiator fins for debris or damage, and gently clean if necessary.
Step 4 – Reinstall Drain Bolt
- Once drainage is complete, securely install the drain bolt and washer. Do not overtightenrefer to your service manual for the proper torque specification for the EC200.
Step 5 – Add New Coolant
- If your coolant is a concentrate, properly mix it with distilled water as recommended (typically 50/50). Pre-mixed coolant can go straight in.
- Slowly fill the radiator until the fluid reaches the filler neck. Do not fill too quickly—allow air to escape and prevent bubbles from forming.
Step 6 – 'Burp' the Radiator
- To remove trapped air, start the engine with the radiator cap off and let it idle briefly.
- Gently rock the bike side to side and blip the throttle. Watch for bubbles escaping.
- Once bubbling stops and the coolant level settles, top off as needed and reinstall the radiator cap securely.
Step 7 – Check Coolant Level & Leak Inspection
- Double-check the coolant level after a short ride as levels may drop once more air escapes.
- Inspect the drain bolt, hose clamps, and radiator for any sign of leakage.
Special Notes for EC200 Owners
- The EC200's two-stroke engine is more sensitive to overheating than many four-strokes, so coolant condition is especially critical.
- Always use the recommended coolant and mixture ratio for your GAS GAS. Avoid tap water, as minerals can accumulate in the radiator and cause internal blockages.
- If you regularly ride in muddy or sandy conditions, check your radiators for debris after each ride to ensure proper airflow.
- The coolant should be changed at least once per season or every 12 months for optimal operation, even if it appears clean.
Final Tips
- Dispose of old coolant responsibly, as it is hazardous to both people and pets. Take it to an appropriate recycling or waste facility.
- If you notice persistent overheating or coolant loss, inspect the water pump seals, radiator cap, and hoses for wear.
