SOURCE: overheating problem
looks like you have done everything but the problem with your car is that the cylider head gasket has gone have a look at the dipstick or remove the oil filler cap if it looks like mayo then 100% head gasket has failed you said no water on the floor so it must have gone into engine only way this can happen is head gasket failing, if you have put lot of water in to the cooling system then your sump will be full of oil water mix.
let us know your findings so we can help you more if you need it
SOURCE: antifreeze ts boiling back into reservoir.
it sounds like a possible head gasket problem,you can get the fluctuation from combustion gases getting pumped into your cooling system and creating gas pockets,i would suggest taking it to a shop and have them do a block test to look for combustion in the cooling system to confirm the problem,that way you will know for sure,if it comes up negative they can also perform a flow test to make sure there is no restriction in the cooling system such as a plugged radiator or a bad thermostat,hope this sheds a little light on it
Testimonial: "I bet you've hit on the problem ! Car has been "using " antifreeze for a couple years now, with no leaking anywhere. Lost through the head gasket ?"

possible head gasket do a preasure test on the coolant system to see if it loses any coolant or presure drops and check for leaks hope this helps
SOURCE: My 2002 Montana Van will over heat while idling,
These fans should turn on at about 220 degrees, give or take a couple, and then turn back off at about 210 degrees.Fans should also come on when engine is idling with the a/c on [provided the a/c works of course] If the fan[s] isn't running and the gauge is over about 3/4 of the way or will go all the way to the end then odds are your fan's aren't capable of working for some reason. The classic symptoms of a cooling fan not working are what you are describing: Cools fine at highway speeds, overheats at slow speeds. I would start by checking the cooling fan fuses located in the underhood fuse panel. I believe they are marked Cooling fan 1 and Cooling fan 2 and both should both be 30 amp fuses. If the fuses are good then you might have problems with the fan motors themselves. Hope this helps you get it working again!
