A common problem is that the electric fan will not operate. You need to determine if the fan is coming on when the vehicle gets warm.
When you replaced the coolant, were you sure that you got all of the air out of the cooling system? If you have any air in the system, it will cause your system to run hot!

where the coolant is going and why the gauges go nuts are probably not the same problem. sounds like your gauges have a problem with the ground side connection to power. you could look at the negative battery post and see if it is really gunked up, might as well check the positive side while you are looking. if the battery posts get oxidized pretty much everything gets a not so great connection but gauges are one of few places you notice it. the car only runs off the battery at startup or if momentarily car is using more amperage than alternator can provide, but current runs through battery from alternator so bad connection there will cause whole system to function less than optimum. in the cooling system one component you don't mention replacing is the heater core. you say the coolant is not on the ground, so where can it be? pull your oil dipstick and see if your oil looks like oil. if it looks like vaseline, kinda white and creamy, you just figured out where your coolant went and you have a blown head gasket. hope that's not it, it's sort of a hassle. there aren't too many other places for the coolant to go. it either runs on the ground, boils off against the hot block, like if it comes out near an exhaust manifold (and that makes quite an odor) or gets into the oil through blown head gasket. it can make it into the passenger compartment through a leaky heater core and if that happens you will smell a sort of sweet smell in the car and after while get a green cast to condensation inside windows. hope that helps.

with your description it sounds like your fans are not coming on, also sounds like the problem was never solved, sounds like you threw a lot of money at your problem also... check to see if the fans are coming on at the right times, seems like a n air movement over the radiator since you say it only gets hot in stop and go traffic... well when your driving at a constant highway speed guess what you have air movement through the radiator... check also a clogged ac condensor with bugs, pressure wash it out so the air can pass through it easily... please rate my help thanks
