Wash away the antifreeze and dry out the area. Start engine and note where the anti freeze is coming from. There are a few coolant hoses and pipes around the area and could be from them. When engine heats up, pressure would build up and sometime hoses have pinholes that would not leak under normal circumstances but would do so after it heats up.
Though a pressure test have been done, it could sometimes not be comprehensive as the time taken could be too short.
