What is your question?
Heater core was leaking so I put Stopleak in it. I quit but my engine overheats now. Dumped the coolant and pulled the thermostat and flushed it out but it still overheats and the heater core still leaks. Arrrrrrrrrgh!!

Until the heater core is replaced the cooling system will overheat because the system runs under pressure, Replace the heater core and hope that the stop leak didn't plug critical coolant passages.
