20V Coolant Flow

[Vezza]

Hi guys,
Can anyone please clarify whether a 20V block has a coolant barrier between the left and right half at the front of the block? Or does it require the metal tab on the water pump to direct the flow to the left of the block? Pics below will make it easier to understand.


Standard 20V water flow. Is there a barrier where the red line is, separating the left and right side of the block?



...or does it need the metal tab on the water pump to block the right side and for the coolant to flow to the left side first?

There is no seperating barrier inside the block where you show the red line.
The metal tab , on the water pump , is obviously there for a reason.
