You can fill the car level.
Remove/disconnect:
-Front radiator fill cap
-Upper heater hose at the heater core connection
-Whatever you have at the back for a fill cap.
Fill coolant until the level gets up to the front radiator fill cap
Install front fill cap
Continue to fill until coolant shows up at the heater core side of the upper heater core connection (yes, it'll dribble out the tube a little bit)
Re-connect the heater hose
Fill to full at rear fill point
Fill front overflow tank to factory full mark (if applicable)
Run up to temperature and allow to cool completely. You'll need to watch the level in your expansion tank while it's cooling
Top off coolant at rear fill
Done

We tried this and it worked for a bit. Eventually we would let the coolant sit over night and it would drain from the overflow. However, there are 4 gallons in the system and I’m not sure where it’s all at as the radiator is dry. No coolant in oil... I suppose the system is just much bigger but I was still a bit concerned.
Thanks for the info!

Most people seem to run the battery lines along the gas tank. Unless they are uncovered, I didn’t see a way to do that nicely. So, we ran them under the carpet. I’ve seen people run it through the center console, but not the carpet. So maybe there’s a reason people don’t go under the carpet, but it seems to work for me so far.

You take cap off the radiator and fill the system until coolant comes up to the lever of the radiator cap and then after some run time and thermal cycles the radiator is dry?
Do you have the original Fiero overflow bottle connected to the overflow port on the radiator?

I am hopefully gonna refill the system again today. The other day though after running the car, the radiator was dry even though I had seen it full before starting it.
I do not have an overflow bottle up front yet. My car was missing one and I’ve been meaning to get one from the scrap yard.

Stock type radiator?
Possible you blew coolant out the overflow port as the system warmed up?

The PO had run over something at some point. There is also a puncture through the main floorboard that’s not as structural as this one that’ll get fixed eventually.
Here is the patch. I painted it after it cooled.
After that, I ran the car for some friends, and found a puddle under the car. Coolant must’ve finally made it to the heater core, and as it was coming down the cool line it showed us this leak. Presumably, water was in the tube and froze, where it burst. It was hidden under the foam. The cool line ended up having several pin hole leaks, as well as a crushed spot, so we cut out the bad section, and replaced it with rubber hose. The metal sections that were kept were inspected, cleaned, and painted. The hot tube was inspected, and because it was covered in insulation it was in great shape with no corrosion.
We then decided to run the heater lines different than what they were. Both lines came out on the passenger side, but since they needed to come out on the driver side it made more sense to cut them shorter and run them directly towards driver side. I’m not sure why I didn’t think to do this before.
Both heater lines now run with each other. I am not a fan of so many clamps, so I hope this all holds. If not I’ll run a solid line.

The PO also didn’t have shocks. So I ordered some new ones. The passenger side had the lower mounting hardware, the driver did not. Took some digging to find the bolts online.
These bolts here are an exact match to what should be on the car.

Now both shocks are in.

I’m definitely gonna read into this! The POs ripped out my AC, so if I plan to reinstall I’m sure it’ll be a project.
