Though it is only meant to be a long lasting temporary measure, most car oriented stores have a powder product that you put into your radiator and it settles to plug the hole. A better solution is to stick with liquid and with a known brand. http://www.wynns.ca/pages/english/e_products_x-cool.html RADIATOR STOP LEAK Add to Coolant as needed or after Radiator Flush.

In the radiator in the front of the engine
Connected to the upper radiator hose. Coolant flows from the engine to the radiator to be cooled. The coolant temp. sensor should be screwed into it.
The coolant temp sensor screws into the thermostat housing. This is located where the top radiator hose connects to the engine.
Check the fan relay for the 1996 Cavalier. Also, check the coolant sensor, one of these is most likely bad.
* With the engine cold remove the radiator cap * Move a large container under to catch the coolant as you drain it * Drain the radiator by opening the drain plug at the bottom on the left side
If there is a cap on the radiator you can check to see if the radiator is full , and if it isn't , " top up " the engine coolant . Otherwise , you check the engine coolant level at the engine coolant reservoir when the engine is cold and maintain the level at the cold mark
It's on the upper radiator hose that runs to the back of you engine. It's a little screw that is on a metal connector. I know because we have a 2000 Cavalier with it on that hose.
Radiator stores engine coolant for circulation throughout the engine The radiator is placed at the front of the engine and exposed to the atmosphere to keep coolant cool to maintain proper engine temperature
Open the radiator cap and pour coolant in. If you're filling an empty system, you'll want to leave the cap off, and run the engine for 30 minutes or so to 'burp' out any air in the system, then top your coolant off again.
Coolant outlet adaptor(upper radiator hose) Close to the power steering pump. Its always closest to the coolant outlet that LEAVES the engine.
The hose coming from the thermostat housing connects to the upper part of the radiator and allows coolant to flow into the engine...
It's either and/or... Low coolant, Thermostat, Faulty temp sender unit, partilly clogged radiator, Radiator cap not maintaining proper pressure, Bad cooling fan not coming on, Head Gasket is bad, cracked Head, Water pump defective.
