As you all know the inside temperature inside the Coupe can reach pretty high values. Unfortunately mine is not equiped with aircon
However last year during a hot day I discovered that there is a pretty hot airflow over the roof and along the side windows. This can only be caused by the hot air coming from the radiator. When you stick your had out it's very easy to notice. About 4 inch above the roof or out of the window the air is much cooler.

So my question is has anyone did some investigations about how to control this ? It would make a big difference if cool air would flow into the interiour instead of hot radiator air.
