How to Change the Coolant in a 2014 GAS GAS EC300F
Maintaining your 2014 GAS GAS EC300F is crucial for peak performance and engine longevity. Changing your coolant regularly prevents overheating and corrosion inside the cooling system. Here’s a step-by-step, model-specific guide for a robust coolant change on the popular EC300F.
What You Need
- Recommended motorcycle coolant (avoid automotive coolants)
- Drain pan
- Socket set or wrenches
- Safety gloves and eye protection
- Clean rags
Preparation
- Ensure the engine is completely cool before starting.
- Place the bike on a stable stand and clean the radiator area to prevent debris from entering the system.
Step 1: Locate and Remove Radiator Cap
- The radiator cap is typically on the upper right side of the radiators. Remove the shrouds if needed for easier access.
- Twist the cap counterclockwise and set aside.
Step 2: Drain the Old Coolant
- Position the drain pan directly under the water pump cover, located on the right side of the engine.
- Using the appropriate socket, remove the coolant drain bolt at the bottom of the water pump cover. Some EC300 models may use a lower radiator hose as a drain point–loosen the clamp if so.
- Allow all coolant to fully drain. Tilting the bike gently side to side helps evacuate old fluid from both radiators.
Step 3: Inspection
- Inspect the drained fluid for dirt or particles that might indicate internal wear or corrosion.
- Check the radiator cap seal and rubber hoses. Replace if any cracks, hardening, or leaks are spotted.
Step 4: Reinstall the Drain Bolt
- Once drainage is complete, wipe the area and reinstall the drain bolt or hose. Tighten to manufacturer torque specifications (typically 8-10 Nm but consult your EC300F manual).
Step 5: Add New Coolant
- Slowly pour fresh motorcycle coolant into the radiator until the level rests just below the filler neck.
- Lean the bike left and right a few times to help bubbles escape. Add more coolant if needed until full.
Step 6: Bleed the System
- With the cap off, briefly start the bike and let it idle for about 30 seconds. Watch for air bubbles rising.
- Shut off the engine and top off the coolant if the level drops.
- Reinstall the radiator cap, ensuring it is fully seated and locked.
Step 7: Final Checks
- Check for leaks at the drain bolt and hoses.
- After your first short ride, verify the coolant level again and top off if required.
Special Considerations for the 2014 GAS GAS EC300F
- The EC300F features dual aluminum radiators with cross-flow–both sides must be drained and filled adequately.
- Factory hoses and the radiator cap may degrade over time; inspect or upgrade with high-quality silicone hoses to prevent unexpected failures.
- Never mix coolant types. If switching to a different formulation, flush the system with distilled water before filling with new coolant.
- The EC300F’s powerful four-stroke engine relies on precise cooling, especially in enduro conditions–always use the correct coolant mix for freeze and boil-over protection.
