    if you have the 2 bolts out of the housing, that's it. You may just have to pry it a bit.

    What engine?

    2.2 or 3.4 liter?

    If its the 3.4 liter sometimes it helps to remove the throttle body so that you can see a little easier. I have also heard or people removing the crossover exhaust pipe to gain more access.

It will wiggle out of there, but the thermostat has to come with it. I have found it to be much easier to remove the throttle body, it gives you much more room to work. You don't have to take everything off the throttle body either.

How hard is it to change the thermostat on a 2002 grand am v6?

Not hard at all. Looking at the vehicle on the right side you should see the upper radiator hose, connected to it you should have what they call the "thermostat housing" remove it and the thermostat should be there. Replace it and the seal. A 6 min fix

My 2002 Pontiac Montana gets to hot in a short distance. I don't know what it is I have an idea it's either the thermostat or a blown head gasket not sure which one. So which one is it?

You would need to figure out if the thermostat is stuck closed, or not.
Most mechanics would either replace it or take it out and run the engine without it as a test. If the engine still overheats with the thermostat out, it could be a faulty water pump, restriction in the radiator, or other problems.
A blown head gasket should leak coolant out on the ground or into the engine.

2002 Pontiac Grand Prix Thermostat

as you face the engine the thermostat bell is on the right (drivers side) Follow the radiatoe hose. Remove the two bolts and raise the bell still attatched to the hose. the thermostat is there with the rubber seal. You can gently pry the thermostat out with a screwdriver or something similar. Put in new thermostat be sure it is the same as the old one, and then replace or change the seal (be sure it is the smae size and thickness as the old one as I got the wrong size from Napa) Then replace the bell, and tighten, but not over tighten. I hope this helps!
