1988 c4 vette direction of coolant flow to heater core
1988 vette coup...I need the direction of coolant flow from engine/radiator, water pump to heater core and which port the input and output of coolant to the heater core. One of my heater hoses has a "t" coming off of it and I don't remember if that goes into the TOP port or BOTTOM port of my heater core. THANKS! (see attached picts).
