Man Verses Heater Core
Hello all,
Recently my heater core popped and sprayed all over the cab, I filled the radiator and double checked the problem.
Anyway, I like my heater and I want to replace the heater core so I can cruise around at night again...
I have a 1977 F150 with 351M 4 speed and air conditioning, I think I have AC (It doesn't work, but I have a pump and the vents for it)
I have removed the 3 bolts from the engine compartment, unplugged the wires, disconnected the cables, and wiggled that thing until I was ready passout (using prybars and all leverage I could get)
any tips? It doesn't wanna come out, Here are some photos....
Please help...

I have a 1977 F150 with 351M 4 speed and dealer installed Economy A/C (It doesn't work, but I have a pump and the vents for it).
Dealer installed Economy A/C has two A/C switches that fit into a panel that also contains two registers. This panel fits into the dash to the left of the glove box (as pictured above).

So I know I had troubles getting mine out before. So I decided to go look at it. It looks like there may be a screw in the bottom left corner towards the driver side. Also, there is several screws holding the "human operated vent" to the main heater box. I apparently had to get all those screws out and when I put it back in I left the top 2 out because there was no easy way to get to them. I got an AC system like that out of a parts truck one time and I think it was a complete separate "black box" that went in the hole above the normal heater box and behind the glove compartment.

No big box in the engine compartment, so yes dealership installed a/c.

Re
From the pic it looks like my heater only box
As per other post
Take out the fresh air vent.
Reminds ve heater hose and 3 nuts in engine bay.
Remove the backside dash bolt next to pass side door. Below the far right vent.
Have someone pull dash out about 1 inch and heater will slide out through the larger opening available
Hope this helps
