Ok, get yer laughs out first. My brother's 2009 Cobalt SS turbo runs around 197 F in normal driving and his cooling fans always seem to be running. He says he's got a 180 F thermostat in it and he swears, sometimes profanity-laced, that the engine should never get hotter than what the thermostat rating is. I on the other hand have tried to tell him repeatedly that the rated temperature is only an indication of when it would be fully open, and any engine will get warmer under a load. Who's right? Me, I hope.
His car has some cooling system or related sensor issues. For example, even in the winter the cooling fans are almost always running which seems to overcool the radiator and the upper hose stays cool as well. With both fans unplugged, the upper hose gets hot as it should and the coolant temps seem to be a bit lower for some reason. Also when the heater in his car is on, his coolant temps seem to be a bit higher than if the heater is off which seems totally backward to me.
