I have a small amount of antifreeze leaking, it will take 3 days to leak out completely.

I have replaced the thermostat (100K ago), Water Pump (5K ago), and just replaced the coolant elbows.

The leak seams to be coming from the passenger side, in the back under the alternator (might not be where it is originating from but if you look underneath it drips below the alternator area)

What else could this be?
