How to Change the Coolant in a 2024 GAS GAS MC450F FACTORY EDITION
Routine coolant changes are critical for the performance and longevity of your 2024 GAS GAS MC450F Factory Edition. This model features a high-performance liquid cooling system needing periodic maintenance to prevent overheating and engine damage. Follow this MotoSport-exclusive guide for a safe and thorough procedure tailored to your bike.
What You Need
- High-quality coolant recommended for aluminum engine parts
- Socket or T-handle wrench
- Drain pan
- Cotton rags
- Protective gloves
Important Model Notes
- The MC450F Factory Edition uses a lightweight, high-efficiency radiator. Never open the radiator cap while the engine or coolant is hot, as pressure can cause hot fluid to spray and result in injury or burns. Always let the engine cool fully before service.
- Inspect radiator hoses and hose clamps for leaks or wear during each service. Overheating or deterioration in these components is more common after aggressive riding or trail use for this edition.
- Improper coolant disposal is hazardous. Use a sealed container and dispose of at a certified location.
Step-by-Step Coolant Change Procedure
- Let the Engine Cool Completely
Park the motorcycle on a level surface and ensure both engine & radiators are cool to the touch. Never perform this service on a hot engine. - Remove the Radiator Cap
Slowly loosen and remove the radiator cap. If you hear a hiss, wait until all pressure is released before fully removing. This prevents sudden spray from residual pressure. - Locate and Remove the Coolant Drain Bolt
On the MC450F FE, the coolant drain bolt is found on the lower water pump cover on the right side of the engine. Place a drain pan beneath, then use your wrench to carefully remove the bolt. Allow all coolant to drain completely. - Flush if Needed
If the old coolant is especially dirty or contaminated, you may flush the system by filling with distilled water, reinstalling the drain bolt, running the engine briefly (with the radiator cap off), and draining again. - Inspect the Sealing Washer
The sealing washer on the drain bolt may be reused if undamaged, but always check for cracks or flattening. Replace if needed to avoid leaks. - Reinstall the Drain Bolt
Tighten the bolt securely but do not over-torque, which could strip threads in the soft aluminum cover. - Add Fresh Coolant
Pour new, compatible coolant into the radiator up to the base of the filler neck. On this model, the capacity is approximately 0.95 quarts (0.9 liters), but always check for proper fill by visually confirming. - Bleed Air from the System
With the bike upright, gently rock it side to side to release trapped air. Start engine and let it idle with the radiator cap off to help bleed any remaining air–watch for coolant movement and top up as needed. - Reinstall Radiator Cap
Once air is bled and level is topped, reinstall the radiator cap, ensuring a secure fit. - Final Checks
After a short test run, shut down and let cool. Check coolant level and inspect for leaks at drain plug and hoses. Top off if necessary.
Tips for the 2024 MC450F Factory Edition Owner
- This model's high-revving engine produces significant heat under prolonged or aggressive use—vigilant coolant maintenance is especially important for track and trail riders.
- If you notice frequent overheating or steam, check for air in the system, low coolant, or damaged hoses.
- Always use the specified coolant type to avoid corrosion and protect the magnesium and aluminum components.
