Overheating after a hose came off

SOURCE: Dexcool vs Green coolant

Yes, if your car currently has Dexcool in it, you must use the Dexcool to refill it.  However, there currently is lots and lots of trouble with Dexcool. In fact there was a lawsuit over the problems with it.  In fact GM dealers, I hear, are doing complete radiator flushes and replacing all the Dexcool with the old fashion green stuff.  If you would like to change your vehicle over, please ask a certified mechanic for more details specific to your car.  I work for an auto parts store and we constantly are advising people of this Dexcool issue.  
Any further quesitons, please ask!!!  Please rate!!! Thanks!!!

Check your oil and see if it is milky lookinig...that is a sign of a bad haed gasket....here is the location of the thermostat...unless a different engine size...then post what you have and I'll get you the diagram here:

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.
