Hello I will help you with your question,
You are correct the lines are not crossed they run leftmost to left side and the other to the center.
Maybe this diagram will help but it is not very good for the location
Let me know if this helps
The diagram would not open. Does the flow thur the metal tube before the radiator matter way the flow goes through?
If you only have the cooler in the radiator and not the aux cooler in front of the radiator as well it does not matter which way the flow is.
Let me try with the diagram again, it is a .pdf so you need to have adobe reader installed. If you do not let me know and I will post it by alternate means
