I replaced my thermostat today and turned my car on to see how everything went... well the car started to over heat pulling out of the driveway, so I popped the hood and felt the lower radiator line. Cold, no biggy maybe a defective thermostat. took out the termostat, tested it, worked, reinstalled, overheated. So again I felt the lower line, COLD!!!!

WTF, I am racking my brain to figure out wtf I'm doing wrong. Does anyone know what I'm missing? i know its a pressurized system so I filled the block with water, waited for it to bleed through the top of the termostate and put the lower hose on really quick, and its still fu*king over heating. Anyone?
