How to Change the Coolant in a 2022 GAS GAS MC 350F
Replacing the coolant in your 2022 GAS GAS MC 350F is a critical part of maintaining optimal engine performance and longevity. This step-by-step, MotoSport.com-exclusive guide walks you through the process, highlights nuances specific to the MC 350F, and shares essential model-specific tips for success.
Important Safety Precautions
- Always perform the coolant change with the engine completely cool to avoid burns from hot coolant or steam.
- Ensure the motorcycle is on a stable, level surface and the ignition is turned off.
Tools & Supplies Needed
- 8mm or 10mm socket wrench (check your drain bolt size)
- Catching pan for old coolant
- Fresh, model-appropriate coolant/antifreeze
- Clean funnel
- Shop towels
Step-by-Step Coolant Change Process
-
Remove Skid Plate (if equipped):
For easier access, remove the skid plate if your MC 350F is fitted with one. -
Access the Radiator Cap:
Locate the radiator cap on the right side of the bike, near the handlebars. Do not open while the engine is hot. Slowly loosen the cap to release any pressure before removal. -
Locate the Coolant Drain Bolt:
The drain bolt is typically on the lower portion of the water pump cover, on the right side of the engine case. Position your catch pan underneath. -
Drain Old Coolant:
Remove the drain bolt and let all coolant flow out. To completely empty the system, consider also disconnecting the lower radiator hose momentarily. -
Inspect System Components:
Inspect the used coolant for debris or oil contamination – either could indicate internal gasket damage and warrant further inspection by a technician. -
Reinstall & Torque the Drain Bolt:
Clean the bolt and threads, then reinstall. Tighten to recommended torque – overtightening may strip the housing. -
Refill with New Coolant:
Pour the new coolant slowly into the radiator using a funnel. Fill until the fluid reaches the bottom of the filler neck. -
Bleed the Cooling System:
The MC 350F features a bleed screw (typically on top of the cylinder head). Loosen this screw slightly while filling to let air escape. Once pure coolant flows out and no bubbles are seen, retighten the bleed screw.
Top up the radiator if needed. -
Reinstall the Radiator Cap:
Ensure the cap is clean and the rubber seal is intact. Firmly secure it back in place. -
Run & Check:
Start the engine and let it idle until warm. Monitor coolant level; top up again if needed after the first session, as air may continue to bleed from the system.
Model-Specific Tips for the 2022 GAS GAS MC 350F
- The MC 350F cooling system is shared with other MC-F four-stroke models, but always use a silicate-free, motorcycle-specific coolant for corrosion protection.
- This model's cooling system is sensitive to trapped air. Properly bleeding through the cylinder head screw is crucial for preventing hot spots and engine overheating.
- If you ride in extremely cold climates, check your new coolant's freeze protection rating – GAS GAS recommends a 50/50 mix of coolant and distilled water or a ready-mix compatible with aluminum radiators.
- Periodically inspect all hose clamps and radiator fins for leaks or damage during coolant changes.
Maintenance Reminders
- Follow the factory service interval – GAS GAS recommends changing coolant every 48 months or sooner under harsh racing conditions.
- Always responsibly dispose of old coolant as it is toxic to people and pets.
Keeping your 2022 GAS GAS MC 350F running at peak performance is easy with regular coolant maintenance – and MotoSport is your partner in every ride and wrench session!
