VS - Air Conditioning Heater Core

Heater Cores

Heating is a primary role of air conditioning

Most vehicles are fitted with heating systems and the engine cooling liquid is traditionally used as the energy source for heating purposes. Part of the heat produced by the engine is channelled to the cabin via the heating radiator. The heating components are located inside the Heating, Ventilation and Air Conditioning system (HVAC), after the blower.

The heater core

The heater core has three main jobs:

  • To act as an air and water exchanger, using energy from engine cooling liquid
  • To increase cabin temperature
  • To demist and defrost glass
