How to Change the Coolant in a 2014 GAS GAS EC 450F
The 2014 GAS GAS EC 450F is a high-performance dirt bike that relies on a properly maintained cooling system to handle extreme off-road conditions. Changing the coolant ensures engine longevity, maximum performance, and reliable riding on the toughest trails. Follow this guide for a safe and effective coolant replacement made specifically for your EC 450F.
What You Will Need
- Ratchet with appropriate sockets
- Catch pan or container
- New coolant (use a 50/50 mix of ethylene glycol-based, aluminum-safe antifreeze with distilled water)
- Gloves and eye protection
- Clean shop rags
Preparation
- Park the bike on a stable, level surface and let the engine cool completely. Working on a hot engine risks burns and may lead to injury or system damage.
- Stand your EC 450F upright, using a bike stand for stability.
Draining the Old Coolant
- Remove the radiator cap slowly to release pressure. Set aside the cap.
- Place your catch pan underneath the water pump area – this is typically located on the lower right side of the engine.
- Identify and remove the coolant drain bolt at the bottom of the water pump cover. Allow all coolant to drain completely.
- If you want to perform a thorough flush (recommended when switching coolant types): remove the lower radiator hose so any remaining fluid is expelled. You can use compressed air to clear stubborn coolant pockets if needed.
- Inspect for any coolant spilled on the frame or engine and wipe it off promptly, as coolant can damage painted and metal surfaces and is slippery if left on tires or footpegs.
Refilling with Fresh Coolant
- Reinstall and tighten the drain bolt. If removed, reattach the lower radiator hose and secure the clamp.
- Pour your 50/50 coolant mixture slowly into the radiator fill neck. Fill until you see it near the top of the fill neck.
- Tilt the bike side to side gently to help bleeding and remove air pockets from the system.
- Add more coolant if needed – the system capacity is about 1 liter. Confirm the level matches the recommended fill mark.
- Reinstall the radiator cap securely.
Final Steps
- Start the bike and let it idle until it reaches operating temperature. Monitor for leaks and watch the coolant level through the overflow tank (if equipped) or at the fill neck.
- Shut the bike off, let it cool, and recheck the coolant level. Top up as needed to ensure maximum protection.
Special Notes for 2014 GAS GAS EC 450F Owners
- The EC 450F cooling system is aluminum-based; always use antifreeze formulated with corrosion inhibitors for aluminum.
- Never use tap water in the mix – always use distilled water to prevent mineral buildup and clogging.
- Spilled coolant can create a slipping hazard. Wipe down the frame, wheels, and tires immediately if any is spilled.
- Check hoses and clamps for condition and tightness during the process. Replace any cracked or brittle components for peace of mind while riding.
Stay proactive with your maintenance routine on your GAS GAS EC 450F for confidence in every ride, from trail to track.
