Is the oil cooler somehow directly bolted to the radiator, or is there some kind of bracket between them? I'm of course talking about the upper attachment point. There are brackets in cooler and in radiator, but they are 90 degrees off each other, so I cannot imagine any sensible way to bolt them together with just one bolt, as the parts catalogue insists.
The cooler has been bought separately (one didn't come with the car), but it is supposed to be from a S2 Flavia, and it also looks like in the picture of parts catalogue.
Of course, a close picture could help a lot.
