Technical Is there an air bleed screw somewhere?

[shotaroJPN]

I own a Fiat Ducato Motorhome model 2022.

I need to bleed the cooling system as I have changed the coolant regularly.
I cannot refill the remaining 1 liter or so because the air does not drain out easily, is there an air bleed screw somewhere?

Hi on our 2017 3.0 X290 there is a black plastic fitting with a bleed screw in the middle of the engine compartment where both the heater hoses both go through the firewall. I would think this would be common system regardless of which engine is fitted.
Cheers
