one morning i am warming up car, i realize no heat. pop hood and notice top radiator hose had tiny leak from balooning"old hose"and rubbing on pully. so i replace hose, and top off radiator. I let her warm up, and when it reaches operating temp,and the thermostat opens, it quickly starts to over heat. so i turn off engine. during the time the car was warming up neither heater hose got even warm, but i only felt them right at fire wall.-------so clearly i belive a blockage caused the pressure which caused hose to baloon. "also i replaced thermostat and flushed radiator and block with garden hose about a month ago and everything seemed really clean, no scale or anything" but didnt flush heater core......any help troubleshooting this will be a life saver. thanks everybody
