Do the cooling fans run? Did you get all the air out? Clean the cooling fins on the radiator/condenser, check the belt.

They are the fins you see when you look at the outside of the radiator. Take a garden hose ans spray water from back to front. in other words opposite of the regular airflow. try to spray through the radiator ans condenser at the same timw

This still sounds like air trapped in the cooling system to me. Very common problem in these cars and sometimes just using the bleeder valve is not sufficient. Might try draining and refilling with the front of the car up on ramps or facing uphill. That seems to help. Or you might need a shop with the proper vacuum equipment for drawing the air out of the system to do it for you. Don't cook your engine.
