How to Change the Coolant in a 2018 GAS GAS EC200
Keeping your 2018 GAS GAS EC200's cooling system in top condition is essential for performance & engine longevity, especially during tough rides or racing conditions. Changing the coolant regularly helps prevent overheating, corrosion, and internal deposits that can damage your engine. Follow this step-by-step proprietary MotoSport guide for a professional and safe coolant swap.
What You Need
- High-quality engine coolant (mixed to the appropriate spec for your climate–refer to your owner's manual or product label)
- Drain pan
- 8mm socket or wrench
- Phillips screwdriver
- Funnel
- Clean rags or shop towels
- New gasket or sealing washer (recommended for the drain bolt)
- Torque wrench
- Protective gloves
GAS GAS EC200 Coolant Change Steps
- Allow Engine to Cool: Never open the cooling system while hot. Wait for the bike to cool completely to avoid burns.
- Prep the Bike: Place the bike on a stable stand. Remove the seat and left side panel to access the radiator cap easily.
- Remove Radiator Cap: Use a glove or rag to carefully remove the radiator cap. This will release any residual pressure and allow coolant to drain freely.
- Position Drain Pan: Place your drain pan directly underneath the water pump area on the right side of the engine.
- Locate and Remove the Coolant Drain Bolt: Find the coolant drain bolt on the water pump cover (lower right crankcase cover). Use an 8mm socket to remove the bolt and allow coolant to fully drain into the pan.
Tip: Replace the crush washer or sealing gasket on the drain bolt to guarantee a leak-free seal upon reassembly. - Flush Optional (Recommended): If coolant is very dirty, flush the system by filling it with distilled water, reinstalling the drain bolt temporarily, running the engine for a short time, then draining again.
- Reinstall Drain Bolt: Once drained, clean the bolt and sealing surface. Install with a new gasket and tighten to the manufacturer-specified torque (9 Nm for the EC200)*.
- Refill Coolant:
- Pour coolant slowly into the left-side radiator until nearly full.
- It's often helpful to gently rock the bike or squeeze radiator hoses to help trapped air escape.
- 2018 GAS GAS EC200s have a cylinder head bleeder screw–loosening this as you fill helps purge trapped air. Tighten the bleeder once only coolant (no air) seeps out.
- Check Level and Reassemble: Top up coolant to the lower edge of the cap neck. Reinstall radiator cap, then replace the seat and bodywork.
- Start Engine & Bleed: With the bike upright, start the engine and let it idle for a few minutes. Shut down, allow to cool, then check coolant level again. Top off if necessary–air bubbles may displace coolant after initial fill-up.
- Inspect for Leaks: Verify all seams, hoses, and the drain bolt are dry. Address any drips immediately.
Pro Tips for the 2018 GAS GAS EC200 Owner
- Cooling System Design: The 2018 EC200 uses a two-radiator system with a water pump-driven circuit. Be attentive to possible air pockets in both radiators and use the cylinder head bleeder function if equipped.
- Coolant Formulation: For extended cold weather riding, adjust the antifreeze mixture per manufacturer guidelines. This is especially important for riders in cold climates, as the wrong mix can lead to freeze damage*.
- Gasket Integrity: Always inspect drain bolt and radiator cap gaskets. Damage or wear can lead to leaks and system pressure loss.
- Aftermarket Options: If you wish to upgrade, MotoSport offers better hoses, high-flow water pumps, and advanced coolant additives designed to maximize cooling on your EC200.
Regularly changing the coolant is one of the most important maintenance tasks for your 2018 GAS GAS EC200. Proper care now can help avoid costly repairs & keep you riding longer!
