The cooling system has lots of nooks and crannies that trap air, making it difficult to fill the system with coolant. The fill cap and neck are supposed to be at the high point of the system to help air bleed out, but often they aren't. And even if they are, you need all the natural help you can get. So jack up the front of the car, which gets the coolant fill neck as high as possible.
Check for air bleeds on the engine. Sometimes you'll see an obvious air bleed, such as a bolt-like item threaded into a hose. If there's an air bleed, open it. If there are several, open them all. If you have access to a factory service manual for your car, check it for a coolant fill procedure. Your owner's manual should list location of bleeder valves.
Pour in the required amount of coolant slowly until you see coolant oozing out of the open air bleeds. Then close the bleeds and top off the system with the remaining coolant.
If the system has a heater coolant valve, close it by moving the temperature control lever or knob to cold. With the engine running at fast idle and warmed up, have a helper move the lever or knob to hot while you listen at the coolant valve. If after the first rush of coolant you hear a continuous gurgling noise, there's still air in the coolant, and you need to open the bleed valves again. Be prepared to watch the coolant level in the reservoir over the next few weeks.

Bleed 3800 engine cooling system?
Is the question how to bleed a Buick 3800 cooling system? I would say open that little petcock by the themostat housing and release all the air as you fill the system with coolant. When coolant comes out instead of air all the air is out.

What would cause the heat in a 1991 Buick Skylark not to get warm?
Thermostat possibly stuck open. Another possibility is the heater core is clogged. I would recommend you perform a complete cooling system service. Drain and flush the system with the heater set to high. Replace the thermostat, and install a 50/50 mix of coolant and distilled water. Bleed all air from the system.
