2001 grand am bleeding cooling system

I am having problems getting all the air out of the cooling system. I read another thread which specified to first use the bleed valve on the thermostat housing and then the riser (black pipe) in front. This was for a 99 GA. I can not find the bleeder valve on the thermostat housing only on the riser. The car is running fine at about 200 when driving but it goes up to 205-210 while idling. Does anyone know the proper way to bleed a 2001 GA. Thanks. Any help would be much appreciated.

more info ... its a 3.4 liter V-6
