A heater core in a vehicle takes some of the heat from the coolant and runs it through a heat exchanger. The blower in the car that blows hot air into your car runs through that heat exchanger which heats the air that enters your car.

you probably have air trapped in you heater core you shoud have it flushed/bleed to get the air out. the other possibility is a failing thermostat or water pump
Why is your car overheating and has not hot air in car?
No heat in your car may be from your water pump going out and not feeding your heater core with enough water to produce heat. First remove your thermostat and see if your car stops over heating. If it doesnt, then you need to replace your water pump. Hopefully you havent cracked your heads. If your car doesnt over heat after removing the thermostat, but you still have no heat in the car. Then its your heater core that needs replacing. Always replace your thermostat whenever replacing the water pump.
