First remove the plastic engine cover by un-screwing the oil filler neck from the engine (not just the cap but the whole tube). Lift off cover. Then find the thermostat housing (follow large hose coming from top of radiator). Get a rag or towel so coolant doesn't splash on you. Locate the bleeder screw on top of the thermostat housing (10mm screw). Run the engine for 5 mins. or so until it gets up to temperature. Leave engine running and slowly turn the bleeder screw counter-clockwise until only coolant is coming out. Re-tighten screw and replace engine cover. I just replaced the thermostat on my '04 so I know it works.
I just did this and the screw is a two piece screw, the 10 mm part need not be turned on my car ('04 GP GT2), instead the top part of the screw which was a 7 mm is to be turned to let the system bleed off.

There is a high probability that the system needs to be bled. As in bleed the air from the system. Just filling the system is not enough.

on the side of the thermostat housing there is a small screw with the motor is running make sure the heater is on loosen the screw let the water run until you see a steady flow then tighten back up. I disagree with the previous poster. The cooling system is bled by loosening the screw on the metal pipe just behind the water pump housing. The pipe goes upward off the housing and has a bleed screw on the end of it. To Bleed the cooling system, turn the heater to full hot and open the screw and add coolant to the resevior until you get a bubble free flow of coolant from the bleed screw. At this point the system is bled and just tighten the screw.

How do you bleed cooling system in a 1995 Pontiac grand am with quad 4 engin?
These engines take care of themselves... They have a air bleed tube coming out of the water outlet, which is located under the power steering pump on the drivers side. This tube runs back over to the fill tank. This system does not have a cap on the radiator, just on the fill tank. This is correct on the 97 Buick Skylark 2.4 Quad 4 which I have.
Still no power steering after changing the power steering pump and rack and pinion in 96 Pontiac grand am what next?
