Coolant drain

[tinymartin]

Hello everyone. I have a fiat ducato 2.3 automatic diesel 140bhp motohome and its a 21 plate. I want to adjust the antifreeze reading, can anyone please tell me where the coolant drain plug is or the best way to drain the system so I can adjust it. Thanks in advance

For simple adjustments it may be appropriate to suck fluid out of the resevoir.
unfortunately i dont know where the coolant drain plug is or the best way to drain the system.
