What does the heater core connect to? The heater core is part of continuous loop of engine coolant propelled via the water pump, flowing through caverns in the engine, through pipes that run through the firewall into the heater core, back out the firewall, and finally through the radiator
Radiator
Radiators and convectors are heat exchangers designed to transfer thermal energy from one medium to another for the purpose of space heating. Denison Olmsted of New Haven, Connecticut, appears to have been the earliest person to use the term 'radiator' to mean a heatin…

These hose connections are usually found on the passenger side of the engine firewall, but may also be found near the middle.Oct 29, 2021
Where do the heater core hoses connect?
The upper radiator hose is connected to the thermostat housing and to the radiator. From the bottom of the radiator, is the lower radiator hose that is directed to the water pump. Powered by the vehicle's water pump, the engine coolant loses its heat after passing through the radiator.
Is the heater core connected to the radiator?

When you turn on the heat inside the car, a valve is opened so hot coolant can flow to the heater core (on some cars ), or a door is opened to direct air through the already hot heater core.
Why does my car heater blow out cold air?
If the heater suddenly starts to blow out cold air, the car has most likely developed a leak and lost all its antifreeze. Without coolant the warning light or temperature gauge may not even indicate a problem, because it is not able to read the temperature of the now empty water passages.
What happens if a water heater blows cold?
If, however, the heater suddenly blows cold, and the temperature starts to climb, the belt that drive the water pump (or the pump itself) has most likely failed.
