I guess you are hedging on protecting your engine when a new 951 for 92 F-body is about $100?
There is a metric ton of diagnostic misinformation in this thread, some probably / hopefully tongue-in-cheek.
Use a UV laser thermometer, see what the temp. difference is between the top and bottom of the core.
If the bottom is significantly cooler than the top, or doesn't warm up commensurate with the engine coolant outlet temp, things are likely blocked, making it worth your while to diagnose further. Usually, removal of the lower hose lets you readily see corrosion at the lower tube ends of the core. Maybe your system had poorly maintained coolant mixture and it happened quick (in 2 years, assuming you bought it new.) Either way, you have multiple signs your radiator has some blockage. Confirm and replace. Your t-stat is easily tested with a thermometer and pan on the kitchen range.


Good thing you stopped by to clear up all the misinformation !!

There is such a large difference in the temp of the bottom of the rad and the lower hose and the top of the rad and the top hose, the radiator is most likely the culprit, again considering the fact it was frozen 100% solid. It has a derpy el cheapo parts store radiator (I got it off summit, but it's the same sh*t they sell at the parts store), and it arrived bent, and I've replaced the bypass block off cap twice due to it cracking swelling and exploding. I've actually been meaning to replace it for a while (if anyone remembers my "Drop in radiator under 300$" thread...), but life gets in the way. especially when you work 6 days a week most times and the car in question is your only car. Since I bought my suburban, once that is running, the regal will get all the stuff it needs. Radiator included.

This thread can be over now. :D

Replace or test the thermostat.
