Lincoln Ls 2005 overheating problem

I don’t know what it’s leaking but it’s
leaking from the bottom hose on the left
side the 2 close to the top a/c has never
worked or heater (we’ve had it for a year)
but it’s leaking something fierce. The car
starts over heating about 30 seconds to a
minute of driving it. Pretty sure it’s not the
head gasket cuz the oil doesn’t look like
chocolate milk but I’m not sure.
