I gave it a look over when the engine was hot. The little weep hole underneath didn't appear to be seeping....It all seems to be coming out of the black overflow tube and down the side of the radiator. But I've had the radiator pressure tested and it was fine. Replaced the cap with 2 new ones. The first one had a bad gasket on it. It doesn't smell of antifreeze at the exhause and doesn't show the white smokey looking exhaust while running.....
