How to Change the Coolant in a 2008 GAS GAS EC200
Regular coolant changes are essential for keeping your 2008 GAS GAS EC200 running cool and protecting the engine from corrosion and overheating. Follow these step-by-step instructions designed specifically for your EC200 model:
Required Tools & Supplies
- Cordless screwdriver or ratchet
- Drain pan
- Fresh coolant (GRO GCC 30% Long Time or similar high-quality premix, as recommended)
- Funnel
- Rags
- Protective gloves
Step 1: Prepare Your Bike
- Park on a stable, level surface and allow the engine to cool completely to avoid severe scalding. Never open the radiator cap on a hot engine–pressure and hot fluid can cause burns.
Step 2: Remove the Radiator Cap
- With the bike cool, carefully remove the radiator cap to relieve any residual pressure in the cooling system.
Step 3: Drain Old Coolant
- Locate the coolant drain bolt–typically found at the lowest point on one of the engine covers or at the bottom of the radiator.
- Position your drain pan underneath, remove the bolt, and allow all the old coolant to completely drain away.
- If equipped, also drain the overflow reservoir and inspect for debris or discoloration. Clean the reservoir if needed with a bottle brush.
Step 4: Inspect Cooling System Components
- Check radiator hoses for cracks, chafing, or brittleness. Gently squeeze the hoses–if they feel stiff or cracked, replacement is recommended.
- Inspect hose clamps and radiator for tightness and ensure the cooling fins are not bent. Lightly straighten bent fins with a small screwdriver.
Step 5: Reinstall Drain Bolt
- Once old coolant has fully drained, clean the drain bolt and reinstall it, making sure it is securely tightened but not over-torqued.
Step 6: Add New Coolant
- Using a funnel, slowly fill the radiator with the recommended coolant type until near the top opening.
- Fill the overflow reservoir to the indicated level, if equipped.
Step 7: Remove Air from System
- Important for the EC200: Air bubbles can cause hot spots and overheating. To bleed the system, rock the bike gently from side to side and tap the radiator hoses to encourage bubbles to rise. Top off as needed.
- Start the engine and let it idle with the radiator cap off for a couple of minutes. Watch for bubbles, top off if the level drops, then reinstall the cap once the system is full and free of bubbles.
Step 8: Inspect for Leaks & Clean Up
- Check beneath the bike for leaks around the drain bolt, hoses, and reservoir.
- Wipe up any spilled fluid and properly dispose of the old coolant.
EC200 Owner Notes
- The 2008 GAS GAS EC200 uses a closed-loop liquid cooling system crucial for maintaining top engine performance in all climates.
- Recommended coolant change interval is at least every two years or 40 hours of operation, whichever comes first.
- Always use a non-silicate, motorcycle-specific coolant to prevent corrosion and maximize the lifespan of internal engine components.
- Routine inspection of all cooling system parts will help catch leaks or potential failures before they become problematic.
