79 AC Assembly Drain Plug
Hey everyone, I started my F350 the other day and I am leaking a lot of antifreeze from the drain that is circled. Does anyone know if a drain plug is supposed to be in there? If so does anyone know the part?
Thanks, James

That's a place a rubber hose attaches with a semi stiff closed end on mine, it lets the water collected on the evaporator core to drain out on the ground and not in the floor. If dripping engine coolant, you either have a leaking heater core or a loose ill fitting heater hose.

X2 drain for condensation. X3 sorry to say I bet bad heater core. Is it leaking INSIDE the cab on the passenger side floor board or out onto the ground? As in the passenger side inner fenderwell /bottom of the cab front corner area?

Watch this for a disassembly video. The evap box has to be removed to replace the heater core.

Sometimes a leak present when coolant is hot will not show with cool coolant as the system isn't up in pressure.
