Coolant sensor goes off at random times?

Hey guys... so today I ground the coolant sensor, so it does not go mad, and drove my car around a bit, parked it for 2 hrs, and drove some more. The coolant gauge never went higher than 1/2 and since the buzzer didnt go off, it seems that it is NOT a bad wiring in the harness problem.

My question is: how much pressure is there supposed to be in the upper rad hose after the engine is shut down? Mine has a lot of pressure in it. Is it possible that my coolant leak may be a cracked housing and the combustion pressure overpressurizes the coolant system?

also, my car smokes a blue-ish/ white ish color when I first start it up, and id does so for 5min or so until it warms up. How heavy should this smoke be if it sat for like a week? I had it coming out of there like a stove pipe!
