Hi Guys, I am planning on doing an overhaul on the cooling system on my LG4 firebird 1984. The heater for the interior of the car has been totally disconnested so i suspect it was leaking. however I am struggling to make sense of how they have rerouted the pipes. Does anyone know where i can get a diagram of the heating/cooling system so i can figure out how to put the car back as it was. Thanks
