Normal operating temperature problem, whats the normal operating temperature? Options

[mathshop]

hey guys, my gauges have been known to be misleading, like my fuel gauge for half a year been about a centimeter off, so when i was full on gas, it would be at the second bar, and when it would be empty it would be below the E bar, ect... (it eventually fixed itself????)so im wondering what the normal temperature is for a Celica ST, MY teacher at school has a Check Engine thing, which tells all the details on the engine, like rpm idle speed misfires, ect, and my temperature read.... crap i forgot, i think it was 81degrees Celsius. is that normal? well, whatever it is i cant seem to fix it. its about 3/4s way to the top, and has never gone above, or below,. i've changed the thermostat, the coolant where u can check it, is kinda brownish? im not sure if its the Toyota coolant, or it has a gasket leak ? but in the radiator its still green so i dont know, any feedback will help! thanks...
