You might be reading the engine incorrectly.. with the cap on and of Corse the air bleed is done correctly. I've seen this so many times on misread of a overheating condition. The temperature gauge might work but reads wrong and leads you believe the engine is overheating! Drive the car and disregard the gauge and your mind -set and see if you Feel it overheat. Feel means rattling coming from engine and after a long ride see if you see any steam. Make sure when you leave that the engine is free of water around the radiator and around the engine. Go for a ride never mind what you think and feel ! Disregard the symptoms you see under the hood. Some engine run under high pressure. Don't replace the temperature sender either. Dive the Car!.. After your done go to a radiator shop and let them look it.. They typically won't charge you to look at I and tell you wants wrong. Try more then one shop too. Good luck!!
Do a compression test to check for head gasket failure.
It might be better for you to get that checked out professionally. Something tells me though, it is not going to be an easy fix and it is going to cost you some money. You are going to want to get that checked before things get worse.

SOURCE: Thermostat on 2002 Chevy Impala
the best thing to get is the Haynes manual for your car at advanced auto or autozone or somewhere like that and the book will tell you how to take everything apart and put it back. i think the manual is about $16.00

After replacing the thermostat, you must bleed the air from the cooling system.
To bleed air from the 2.2L and 2.5L engines, remove the plug or sensor
on the top of the thermostat housing. Fill the radiator with coolant
until the coolant comes out the hole. Since the plug is made out of
steel and the thermostat housing is aluminum, it is a good idea to
apply an anti-seizing compound or Teflon® tape on the plug threads
prior to installation. Install the plug and continue to fill the
radiator. This will vent all trapped air from the engine.
Any trapped air in the heating system will have to be displaced by coolant. Once the cooling system is filled, with the radiator cap off, turn of the heater at it's highest setting. Start the engine and allow it to reach operating temp. You should see a drop in the coolant level as the air in the heating system is displaced by coolant. Add coolant to the proper level and replace the radiator cap.
Keep a close eye on the coolant level for at least the next couple of weeks. The cooling system is a "closed" system. Any significant decrease in coolant level indicates a problem.
If you have any questions, let me know.

hi..the radiator cooling fan(s) will be replaced by
disconnecting the power (an automotive connector)
then physically unbolting it from the radiator.vehicles
with less room in the engine compartment might require
pulling the radiator, fans and all and then disconnecting it.
