Did you put a new cap on the radiator? Small as it seems, if it does not provide an adequate seal on the radiator, than the system does not get pressurized, thus keeping the boiling point around 212 deg. your engine gets way hotter than than normally. When sealed right, the pressurized system raises the boiling point to close to 300. thats how is works. If thats not it,(assuming it is the last thing replaced) than you might have either a cracked head/ head gasket/ valve guides, cooling ports, basic large dollar items. Lets hope for your sake the problem is still in the cooling system, before you look at the motor. If you take out the sparkplugs, you'll be able to tell real quick, rusty, burnt whitish-orange looking condition. Good luck

did you check the transmission heat sensor or the intake air sensor these can be incorporated with temp guage on some vehicles
but theres also the problem of alternator is getting ready to give only
take an electro meter and hook up to cigarette lighter with a 2 post power maker and watch the voltage as your driving try to recreate the conditions that brought this about if the reading changes dramatically this will tell your alternator will need to be replaced at some point also dead cells in battery creates this little bump in electrical

SOURCE: temp gauge reads hot when cold
That wire you are unplugging is pinched and being shorted to ground ! You need to trace that wire until you find it . Also if anyone has done any repairs recently you may want to start looking in that area .

replace coolant sensor connector?if so can u get a thermo lazer gun to check the block temp? this will tell u if the gauge is incorect,,,go ahead a bleed all the air out of cooling system and see if that does the trick

You need to unplug the coolant senor that was replaced and see if the problem still exists,if so the wrong sensor was replaced.There is one that runs the cooling fan and one for the temp guage.
