Default 1997 Camaro Z28 overheating

I change the waterpump last week on my car, started it up and the temperature keeps going up so high.
So I checked it myself everything seemed right I taught mayb it was the temp sensor and changed it but no didn't seem to be the problem.
So I took it to a mechanic he said maybe it was the temp sensor that had came out defective so I went to go get another one and same problem, he tried to fix it, got it back a few hours ago and same problem. So took it back to him.
Before I change the waterpump the car didn't overheat, I change the waterpump bcuz the bearing in the back was no good and was making a loud noise.
What can be the problem this my only car I need it back fasst what are somethings that can be making my car overheat?

There's no use in speculating until you know you've taken care of the most obvious issue.

Another way to bleed the system is to have your car cold. Open both bleed screws and fill the radiator. When coolant comes out of the bleed screw of the thermo housing, close it. top off radiator. Wrap a towle or rag around the filler neck of the radiator and put your mouth to the neck and blow into it. Sounds dumb but blowing into the coolant will push any air that is trapped out of the other bleed port. When coolant comes out of it, close it up and top off radiator if need be.

and update.
yesterday the mechanic taught he had fixed the car, he told me he had it on for 30 mins and that it didnt overheat.
later my brother picked it up and drove it around town and the temperature keeps going up so high and wont come down so he took it immedately back to the mechanic again.
today i spoke to the mechanic he told me he did bleeded but i now have bad news the car dont start up anymore!
im really worried what else can it be?
