Its fine in traffic the fans control the temps lovely...
The cooler is mounted as per airtecs intructions. Vertically.

Ive had a play with it and it seems that the flow of water is equal to either side of the turbo cooler, so no water flows through it, its just reaches that point and becomes a stalemate.
The water flowing from the turbo is flowing as it should be, but the little return in the rad is pushing water out rather than letting water return to the rad... Anyone else experienced this?
