I agree, that gunk you put into the cooling system is more trouble than its worth. You risk plugging up the radiator and/or the heater core. Replacing a head gasket is not a cheap repair either. The last time I had one done on my 94 Cavalier, it was around $1200 to do. Gotta take the whole top end of the engine apart and then send the head out to a machine shop to be milled. An oil change is mandatory and the spark plugs may need to be replaced as well.

Only needs to be milled if you let it overheat.

The ONLY thing I'd use (have used) is Blue Devil. If you follow the directions to a "T" it works. Expensive, but comes with a money back guarentee....

Any of those fast fix products like stop leak are effective at stopping the leak in the hadgasket or radiator, but they also stop a ton of other stuff you don't want them to stop.

I thought that milling the head was SOP then again I am not a mechanic. The first head gasket replacement I did on my 94 Cavalier was not the result of an overheat and the mechanic said that the head had to be sent out to be milled to ensure that it was true. The second time was the result of an overheat due to a catastrophic failure of the water pump and the head had to be sent out to be milled due to warpage.

Dont forget that it takes alot of work (and time) to take apart the top end of the engine. Part of that cost is likely due to the 94 Cavalier having the old pushrod 4cyl so you have to disconnect and reconnect the pushrods to the valves and make sure the valves are set correctly. The overhead cams on the Cobalt I imagine are alot easier to work with.
