Thank you very much for the help. It is greatly appreciated.

Should the first overflow tank be filled all the way then to allow for the second one to be used or is it just there in case it's really hot?

There is an arrow with something in German that points to where the mounting bolt for the first overflow tank is. It is also about where the seam that joins the two halves of the first tank together so I had assumed that this was supposed to be the fill line.

At this rate I will have to learn Japanese and German to figure my way around this car

Thanks again.
