How to Change the Coolant in a 2024 GAS GAS EC 250 – MotoSport.com Guide
Regularly changing the coolant in your 2024 GAS GAS EC 250 is vital for optimal engine performance and longevity. The EC 250 features a sophisticated cooling system requiring careful service to prevent overheating and maintain reliability on trail and enduro rides. Here's how owners of this model can confidently complete a coolant change step-by-step:
What You'll Need
- Approved engine coolant pre-mixed for aluminum engines
- Set of screwdrivers
- Socket or spanner set
- Drain pan
- Clean funnel and rags
- Torque wrench (recommended)
- Gloves and safety glasses
Before You Begin
- Work only with the engine completely cool to avoid burns and system pressure risks.
- Place the bike on a stand or secure, level surface.
Step 1: Remove the Seat and Tank Panels
- Remove the right side panel to access the radiator cap.
- If needed, remove the seat and lift or remove the fuel tank for clear access to the radiator system, following standard EC 250 panel removal steps.
Step 2: Drain the Old Coolant
- Locate the coolant drain bolt – typically found on the lower section of the water pump cover.
- Place a catch pan underneath and remove the drain bolt using a socket or spanner.
- Slowly open the radiator cap to allow air in and coolant to flow out completely.
- Check for any stubborn old coolant and gently lean the bike from side to side if necessary to ensure full drainage.
Step 3: Inspect Components
- Examine the radiator cap, hoses, and clamps for wear or damage. Replace worn or cracked parts to maintain system integrity.
- Inspect drained coolant for signs of corrosion, dirt, or oil – these indicate the need for extra cleaning or further investigation.
Step 4: Reinstall the Drain Bolt
- Clean the drain bolt and its sealing washer.
- Tighten the drain bolt to the manufacturer's specified torque to avoid leaks.
Step 5: Add New Coolant
- Slowly pour the recommended coolant into the radiator using a funnel.
- Fill until the coolant reaches just below the bottom of the filler neck. Avoid overfilling.
Step 6: Bleed the Cooling System
- The 2024 EC 250 may include a bleed screw on or near the cylinder head. Loosen this screw slightly while filling and allow trapped air to escape until a steady stream of coolant appears, then retighten.
- Top off the radiator as needed after bleeding.
Step 7: Reassemble the Bike
- Replace the radiator cap securely.
- Reinstall panels and the fuel tank if removed. Refit the seat.
Step 8: Final Check
- Start the engine and let it idle until it warms up. Watch for leaks and monitor the coolant level.
- Shut the bike off, let it cool completely, and recheck the coolant level. Top off again if necessary.
Key Notes for the 2024 GAS GAS EC 250 Owner
- The EC 250 features a pressurized, closed-circuit cooling system – always use manufacturer-recommended coolant for aluminum engines.
- Inspect radiator shrouds and guards for debris after muddy or wet rides, as obstruction can cause overheating.
- Frequent high-rev riding and demanding enduro conditions may require more frequent coolant replacements.
- Always dispose of old coolant responsibly – it is toxic to people, pets, and the environment.
