How to Change Coolant in a 2023 GASGAS EX 250: MotoSport Step-By-Step Guide
Maintaining optimal coolant levels and freshness is crucial for keeping your 2023 GASGAS EX 250 performing at its peak. Whether you ride enduro, trails, or race, regular coolant changes help prevent overheating, corrosion, and component wear. Follow this MotoSport-exclusive guide and keep your engine protected and cool, ride after ride.
Unique Considerations for the 2023 GASGAS EX 250
- Pressurized cooling system: The radiator cap is rated at 1.8 bar (26 psi). Always allow the engine to fully cool before opening the system to avoid scalding injuries and pressurized fluid escape.
- EFI-specific guidance: This EX model uses electronic fuel injection, not a carburetor. The cooling system design and access points differ from carb-equipped models.
- Check the cold start function: After service, verify the cold start button returns to its base position for consistent starting and operation.
Required Supplies
- Fresh, recommended coolant (check manual for specification—avoid mixing types)
- Basic hand tools (socket or spanner set, pliers)
- Drain pan
- Personal protection (gloves, eyewear)
- Shop towels or rags for spills
Step-By-Step Coolant Change for the 2023 GASGAS EX 250
- Prepare your workspace: Place the EX 250 on a stable stand and allow the engine to fully cool. Do not open the radiator cap or coolant hoses while hot, as the system is under pressure and can cause burns.
- Remove the radiator cap: Rotate the cap counterclockwise (after releasing the button, if applicable) and lift away gently.
- Locate the coolant drain bolt: Find the drain bolt at the lowest point of the water pump cover. Position the drain pan underneath to catch old coolant.
- Open the drain bolt: Carefully loosen and remove it, allowing coolant to completely drain. Dispose of the used fluid according to local regulations.
- Flush (optional for thorough maintenance): Reinstall the drain bolt temporarily, add distilled water to the radiator, and repeat the drain process until the fluid runs clear. Reinstall and torque the drain bolt per spec.
- Refill the coolant: Fill the radiator slowly with new coolant, using the main fill neck at the top behind the front number plate. On the EX 250, watch the fluid level and leave a small air gap below the filler neck for expansion.
- Bleed the cooling system: Crack the small bleeder screw located at the top of the cylinder head (if equipped). Allow trapped air to escape as you continue filling until only coolant exits, then retighten the screw securely.
- Top off and check: Fill the radiator to the correct level and reinstall the radiator cap firmly. Wipe away any spills, and check for leaks around the drain bolt and hose connections.
- Warm up and recheck: Start the engine, allow it to reach operating temperature, then shut it off. After cooling, recheck coolant level and top off if necessary.
Important Reminders for Your 2023 GASGAS EX 250
- Inspect the radiator cap: If the cap is worn, leaks, or no longer maintains rated pressure, replace it. Proper pressure ensures correct boiling point and system cooling.
- Clean radiator fins: Dirt and debris block airflow, reducing cooling performance. Straighten bent fins and remove obstructions while you are servicing the coolant.
- Check hoses and clamps: Replace any components showing cracking, swelling, or leaks.
Keep your 2023 GASGAS EX 250 running cooler for longer with regular coolant replacement. For parts, upgrades, or top-rated coolants, never miss out on the full range at MotoSport.
