My car was over heating I changed radiator ,hoses , thermostat. on 1997 Chevrolet Cavalier

Now wont start and I have antifreeze leaking in one cylinder how can I fix this

Asked by for the 1997 Chevrolet Cavalier
Which engine?
2.2 and had water pump checked
Doesn't sound good, I Don't remember any way coolant can get into the cylinder, but a bad gasket, cracked head, or block.
Thank you ProfessorG
