My apologies for referencing Cooloing Motor...this device is stated/named in the 1979 Porsche 928 current flow diagram as are all the dependent devices. Of course not having a dictionary to translate the terms within the diagram can cause confusion.

I have said you need your MY diagrams, for true reference info which can then be used to determine what is still original and not.

Aluminum...nice detailed info pasted in...where does it originate?
