Heater Matrix

Heater Matrix

The heating matrix (or ‘heater core’) is a small radiator that warms up air before it reaches your cabin. When your matrix fails, choose from a wide range of cheap replacements from CarParts4Less.co.uk.

In water-cooled systems, the heater matrix works by taking hot water from your engine through a hose when you turn on your heating system. The ventilation fan forces air through the matrix. This then warms up the air before it makes its way into the cabin via a number of vents. In air-blending systems, the matrix is constantly hot. When you turn the temperature control, this opens or closes flaps that allow cool air from outside to blend with the hot air from the engine. No matter what heating system your car uses, the heater matrix plays a central role in keeping you warm when driving in cold weather. Next to the loss of heat, a clear sign of a faulty heating matrix is the heavy build-up of condensation inside your car. This may come as a result of leaks which allow coolant into the cabin.
