NO the leak is a clear indication that the water pump seal or the rubber bellows has failed and any stop seal will be moved out of the way by the action of the spinning shaft. Replacing the pump is the fix required.

Engine keeps overheating

I'd start with replacing thermostat (that's the most common fault) Other possibilities; waterpump,leaky hose, radiator cap (not holding pressure), fan belt broken. I'd inspect for belt & leaks - if good replace thermostat.

I have a 2000 cavalier. It was leaking coolant from the waterpump.I put a waterpump on and a themostast and it stop leaking,but it still over heats.

If the level in the radiator header tank has bubbles coming out of it when the cap is off or you can get wet hands by holding them behind the muffler you have blown the head gasket or cracked the head.

Overheating engine

You have gone through a lot of trouble so far replacing parts. I wouldn't rely on rad additives for a fix sometimes they do more harm than good. You could just have an air lock in the coolant system. Did you try running the vehicle without the rad cap for awhile to release any air locks that may have occurred? Have you tried a new rad cap? Hopefully this advise helps you some what.
