- Have a drain pan, rags, new coolant (silicate-free, motorcycle-specific), and distilled water.
Step-by-Step: Coolant Change for GAS GAS MC 250F (2025)
-
Stabilize and Access:
- Secure the bike in a vertical position using a stand.
- Remove side panels or shrouds for clear access to the radiators.
-
Drain Old Coolant:
- Locate the coolant drain bolt on the lower side of the water pump cover.
- Place the drain pan beneath and remove the bolt to let the coolant drain completely.
- Open the radiator cap to speed up draining and ensure full evacuation.
-
Flush (If Needed):
- If changing coolant brands or the system is contaminated, flush by refilling with distilled water, idling the bike (with cap on) briefly, then draining again. Repeat until the water drains clear.
-
Inspect Components:
- Check hoses for cracks or wear and replace if needed.
- Inspect radiator fins and clean debris with a soft brush, taking extra care not to bend the fins–the 2025 MC 250F uses high-flow radiators sensitive to damage.
-
Reinstall Drain Bolt:
- Install a new sealing washer if required and torque the bolt to the manufacturer's spec.
-
Fill with Fresh Coolant:
- Pour the new premixed coolant (or 50/50 mix of coolant and distilled water) into the radiator until it reaches the filler neck. Do not use tap water.
-
Burp the System:
- Start the engine with the radiator cap off. Allow it to idle for a few minutes, gently rocking the bike side-to-side. This helps trapped air escape–air pockets can cause overheating.
- Add more coolant as the level drops, then reinstall the radiator cap when full.
-
Refill Reservoir (if equipped):
- Top off any overflow reservoir to the upper fill mark.
-
Check for Leaks & Final Inspection:
- Visually inspect all seals and hoses for leaks while the engine runs to full operating temperature.
- Reinstall side panels.
-
Dispose of Old Coolant Safely:
- Coolant is hazardous–bring it to your local recycling center or auto parts store for proper disposal.
