Just came down from the garage. Looked around nothing on the manual describing as a air bleed valve. In the engine compartment there were two valve looking things but i don't know what they are for. Both on the pipes, one is at the higher point than the radiator cap.
The smell I get in the cabin seems like a dried antifreeze. I overflow it on Friday and it spilled on the engine, that might be drying up and smelling. Like I said dealer did a pressutre test and couldn't find anything and the floor is dry. Only thing I can think of, it may loose fluid when the car is running from the pipes maybe?
