What does the heater core do in a car?
A vehicle’s heater core carries hot engine coolant and uses air to remove some of the coolant’s energy to disperse it into a moving airstream, similar to a radiator. However, the heater core’s primary job is to heat the air passing through it instead of cooling the fluid in its tubes.
Where does the heater outlet come from on a car?
In some vehicles, this may not be all that easy and you may have to raise it and crawl underneath to locate and touch-test them. One of these hoses is an inlet to the heater core coming from the radiator; the other is an outlet coming from the heater core.
