Hello,
My 1985 GT started overheating a few weeks ago when it was sub-zero temperatures outside, and I haven't been able to make it stop since. After running from cold for five to ten minutes, the car reaches around 260 and the dash indicators start popping up. During the several short trips it took to get it home without overheating, I could visibly see it smoking from the vents outside the vehicle. When I finally got to fixing it, I had to put in new belts as both were no longer present in the engine bay. My father and I figured that the radiator could be run from one of the pulleys, but the issue was still persistent. We've tried filling the radiator with more coolant, and turning on the AC does make the radiator spin, but the engine still overheats.
Any thoughts would be greatly appreciated!

Sorry, but this makes no sense whatsoever.

The radiator still didn't spin despite all the belts being present on the engine. Unless you mean our assumption, then we were making it based on what we had seen on some cars before. I know the Fiero's a weird car, but it was worth a shot.

I think he may be talking about the waterpump....but if not possibly he is mistaken in referencing the radiator FAN with accessory-drive belts...

Sorry if my post was confusing. When I say figured, I don't mean concluded. We just were hoping that the radiator fan might start spinning if we get all the belts back on. This wasn't true with the fiero though. The radiator fan only spins if I turn on the ac. This is my main issue.

I'm beginning to think this is a troll.

The radiator fan only spins when the temperature of the coolant has reached something like 235°, or the AC is turned on. The belts run the water pump, which circulate coolant through the engine at all times when running, and through the radiator when the temp is above 195°. If your belts are both in place, and the car still overheats, my guesses would be: seized thermostat, open the "radiator cap"on the engine, and pull out the thing sticking up from inside (considerable force), then put the cap back on without the thermostat and run the car to see if it still overheats. If it doesn't, simple fix, get a new thermostat, if it still overheats, there may be an air bubble in the coolant system, in which case you need to fill it from the engine "radiator cap", the coolant should be right up to the top of the engine coolant cap. or the water pump could be broken. If this has always happened or has happened since taking it to a garage, check the under car coolant pipes, as sometimes mechanics like to use them as jacking points and crush them, should be very visible if that is crushed.

What? I'm asking for help here. Obviously, I'm not a mechanic. We made a guess and it was wrong. We thought we could fix two birds with one stone, but it only fixed one. I'd really like to drive my car, but no one has even tried to give me a serious response as to why this might be happening to my car. I can upload a video if you are still confused if that will help you understand better.

Potentially, but some legitimate problems can be caused by running a car with no water pump, and if one is not at all accustomed to working on cars, and doesn't have a full grasp on the English language, or simply doesn't know how to put the symptoms into words, it can get pretty strange. I live on the Quebec border, and don't speak French, and some of those encounters are weird, people trying to describe something and it just doesn't get understood.
