    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?

    I found out where it was dripping from, it is right on the firewall and it there isnt a hose attached to it or anything. It is just dripping once the car is warmed up

    3 days to empty what? Just the overflow tank?
    For the record : I am NOT a naked meth-head who shoves rocks up my butt.

    It seems that the condenser is leaking quite a bit of water. My understanding is that the AC cannot leak coolant. There is now visable leaks other than from the Condenser which is leaking lots of liquid. Probably too much, other than that there is no leak. Hoses, water pump, coolant elbows, Thermostat, all seem good.

    Any other ideas on whats causing 2 liters of coolant gone in a couple of days.

    so you got a hose leaking. heater hose, or the coolant tank hose, is the tank bone dry?
