Bleed Screws On Engine 99 Pontiac Grand Am?

[DeStiNyMoMmy6]

Where are the bleed screws on the top of the engine??
I'm trying to figure out if that's whats wrong with my car as to why it's overheating!!

the bleed screws are located one on top of the thermostat housing and other one is over on a cooling pipe looking from front of the engine it will be to the right of the power steering pump.
