I have replaced the ECT sensor
it is overheating when idling. I start the car and let it ran for 20 minutes and it slowly heated up
not sure what else to replace

Overheating in the winter?

I read somewhere that the boxer engines will overheat if the heater core is completely plugged up. Apparently, the heater water opens the thermostat.

Is there a way to test if it is the Heater core? Are they simple to replace?
Yes, see if there is plenty of heat in the passenger cabin area ... crank the heater!!!! ... If there is little heat, your heater core MIGHT be clogged.

On a different note, is your Check Engine Light on, and are your fans turning on when the engine overheats?
