Step-by-Step Guide: Changing the Coolant
- Remove the Right Side Panel:
Take off the right side panel to access the radiator and associated hoses. - Drain the Old Coolant:
- Place your drain pan beneath the water pump area.
- Locate the coolant drain bolt (usually at the bottom of the water pump cover) and carefully remove it.
- Allow coolant to fully drain–open the radiator cap to speed up the process.
- Inspect and Reinstall:
- Inspect the drain bolt and sealing washer for damage; replace if necessary.
- Reinstall and tighten the drain bolt securely.
- Refill with Fresh Coolant:
- Use a funnel to slowly fill the radiator with the recommended coolant.
- Stop once coolant is visible at the base of the filler neck.
- Bleed the Cooling System:
- Locate the bleed screw on top of the cylinder head.
- Loosen the bleed screw until air bubbles stop and coolant flows steadily, then retighten.
- Top off the radiator if needed.
- Secure Components:
- Reinstall the radiator cap and side panel.
- Wipe down all areas to remove spilled coolant.
- Warm Up and Recheck:
- Start the engine and let it idle for several minutes.
- Allow to cool, then recheck the coolant level, topping off if necessary.
Model-Specific Tips for the MC 125
- Always use a coolant that matches the factory specification, as some aftermarket products may damage seals or react with aluminum components.
- Annual coolant replacement is recommended even if the bike is not frequently ridden, since coolant can degrade over time and lose effectiveness.
- When reinstalling the bleed screw, ensure a snug fit–do not overtighten, as the threads in the cylinder head are lightweight.
Warning and Environmental Note
- Coolant is toxic–store and dispose out of reach of children and pets. Immediate washing is required if it contacts eyes or skin, and a doctor should be consulted for any exposure to eyes.
Keep your 2022 GAS GAS MC 125's cooling system in optimal shape, and it will deliver peak performance on every ride.
