Where is the coolant filler on a Fiat ducato?

The coolant filler on a Fiat Ducato is typically located near the engine, often at the front of the engine bay. You can usually find it on the radiator or the expansion tank, which is a plastic reservoir connected to the cooling system. For specific models, it's best to consult the vehicle's manual for the exact location and any instructions related to topping up or checking the coolant level.
