I assume your car is A 2.2, The hardest thing is getting the belt off and back on, Remove the belt, unbolt the alt from the engine, unplug the wires and unbolt the battery wire from it, Its not very difficult to do on this car, If your not very experienced with this kind of thing You can do it still , it should take you about 1 1/2 hours. Good luck.
probably r134a, but check with your manual.
Would have been built for R12, can be converted to R134a.
134-a if quick connect valve is alilable. otherwise if schrader valve is presant then r-12 is required.
You should have this verified but the freon is probably HFC134.
Was built for R12, should be converted to R134a
A 1997 Chevy Cavalier uses a standard 50/50 mix of antifreeze coolant and water. This keeps the engine from overheating and from freezing in the winter.
