About Infiniti Heater Core
The Infiniti heater core acts as a secondary radiator to remove the extra heat from the engine coolant. Since the Infiniti heater core is made up of lots of little passageways with metal fins attached, the air that blows across the part is rapidly warmed up and sent circulating throughout the passenger compartment. Leaks and corrosion from an old heater core can cause damage to your interior and prevent you from getting any heat at all.
