Hello everyone , so i just bought a 84 gsl, im having fun restoring it , but ive knoticed that the heater core was pulled off the cooling circuit , (oh yeah i knoticed on those frezzing 5am work days ) i was wondering if anyone has any pic that could show me how to route it up after i pressure test the heater core??? thanks in advance

 

the heater core sits in a plastic heater box behind the dash directly in the center of the car, bolting to the firewall. the two brass lines protrude from the firewall. here are a couple pics form cars where i've removed the dash for work. you can see the heater core's outer box location:






in this older picture from when i first started the restoration on this 85 GS, you can see one of the brass heater lines protruding from the firewall. the other line to the right goes to the metal coolant pipe. in the picture form the red SE you can clearly see both brass pipes protruding from the firewall:
