Engine Overheating Options

[Araykhel]

I have an ST204 that just crossed over 107k miles and I'm having some overheating issues after the car has had about twenty minutes of drive on it. When my car is driving at normal speeds my indicated temperature usually sits at half, great and normal . But once I let off the gas and decelerate the temperature climbs in no time. I find that idling is the worst and my temperature sits just below the red line when I do so.

I've used the great and nifty search feature to educate myself on all the issues to check/ possible fixes however I still have some questions. The first thing I want to check/ replace is my thermostat however I tried searching for a how-to assuming it wouldn't be a simple swap and found none. Do I need to drain fluids ( ) to do so?

im having a problem with mine to, last couple days it wasnt too bad until yesterday, saw the radiator dump all the fluid next ot the battery. canged the fan temp sensor, changed the thermostat earlier, and my fans wont turn on. i've pulled out the plug to get them to run continously and i think it was still overheating. oil is fine, no smoke. i noticed that if i take the cover off the relay and touch it with a cresent wrench they kick on, so im assuming that they arent grounding out. any help

Edit::: took out the crappy termostat i had from autozone and put the oem from toyota. filled the radiator all the way up. got the temp to stay consistant and in the middle... ughh but didnt get the fans on, my opiniion its hott but it might not be any input.
