Coolant leaks onto ground ONLY when the heater is

yes the heater core is located on the passenger side of the center console of the inside of the car,there is a panel there remove it and you will see 2 silver aluminum lines coming in from the firewall that go into the black box inside the dash the heater core is in there,,,there is 1 phillips screw and 2 slip fittings, and when you slide the heater core out your gonna leak alot of coolant onto the passenger side floor,drain the coolant,but your still gonna leak some in,,,,easy to swap,just take your time and youll be ok,,juswt make sure you clip the clips onto the lines all the way or they will pop off and leak alot,,,lube the new orings with like wd40 or something,,
