Just a couple of questions to get us on the same page. Is your Lumina just a Lumina, or an APV or LS? Next - is your engine a 3.4L VIN X or 3.1L VIN M? The VIN is the 8th digit of your VIN. Also how many miles on the vehicle?
So you had a blown head gasket, replaced them both. You had both heads resurfaced - did you have a valve job also?
New thermostat and gasket, you put the GREEN Prestone back in. Now it overheats quicker than before. You bleed all the air out - while the vehicle was running - you opened the bleeder valve on top of the thermostat housing until it ran steady with antifreeze?
Top and bottom radiator hoses not getting hot - are the heater hoses going into and coming out of the firewall hot at all?
Does heater blow cold or hot inside the vehicle?
I believe without answering the above that you still have air in the system. It is extremely hard to get out.
Please answer back with the above and I will get back to you.
I hope you and your family have a nice Thanksgiving.
