not a mopar question, 09 chev uplander

My son's 3.4 2005 Impala took some time to get air out of his system after WP job
Did it have the brass bleed screws on the top of 2 cooling system parts?

I used to fill cooling system thru a funnel on a heater hose, once coolant started to come out of where the hose attached I plugged that fitting and kept filling till fluid came out of the next lower opening, (rad cap) and so on. Be er had any air trapped that way the bleachers were very helpful.
