Testimonial: "Thanks for the valuable info about my water pumps weep hole. You hit it right on the nose."
Sorry to tell you that your problem is YOU have a Head gasket blowen OR a Cracked head, either way you have to remove the head and take it away for Crack testing and surface grind (max 4 thou) no more.
If all ok when done replace with new VRS and refill with coolant (but turn on the heater to hot before filling to remove all AIR

90's Cavaliers are notorious for problems such as these.
I hate to be the barrier of bad news, but in this case I would suggest that your engine either has a blown head gasket, and/or a warped head.
There is also the possibility that you blew a "soft plug" or cracked the block and that the coolant is leaking out through the base of the engine.
To find out of you have a blown head gasket, you can remove the oil cap from the valve cover and inspect it. If it has a yellow-brown-ish goo that is the consistency of paint, then you definitely have a blown head gasket and coolant has mixed with your oil. Meaning that you likely need an overhall.
You can also check by removing your radiator cap and checking to see if little tiny bubbles come up while the car is running. That is a sign of a compression leak, meaning that you most likely have a crack somewhere in either the cylinder head or the block.
Also, those cars have many very small radiator hoses that are in the middle of the engine and hard to see, find or replace.
In this instance, it sounds like your car has over heated more than 4 times, and once you get to that point you are likely to have fried the engine. This is because the newer engines are mostly aluminum and can't stand that much heat that often.
I would suggest seeking either a new car, or seeking a used engine to replace in your car. A used engine for those is fairly cheap compared to the price of fixing the problems that are likely to have occurred from excessive over heating.

Do you know how the head gasket was tested? I prefer the combustion leak detector.This is placed over the fill reservoir and connected to a vacuum source.The cylinder is then filled with a chemical that changes from blue to yellow when combustion gases hit it Additionally a very good way to check for a coolant leak is a UV light.Antifreeze is very flourecent with one of these.
