Description. The Heater Matrix is a smaller radiator located in the dashboard which generates heat, once the heater in the car is activated a fan blows the hot air from the heater matrix into the cabin. The heater matrix can develop faults, split or even burst.

What does heater matrix do?

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.

Is a heater matrix expensive?

The heater matrix (in most cars) is typically buried within the dash/footwell area, requiring around five to six hours labour to remove and refit everything, so it’s an expensive job unfortunately. The prices quoted here are for everything start to finish, including labour, parts, coolant and miscellaneous.

Why does my car smoke when I turn on the heater?

If the “smoke” has a sweet smell with it then it could be steam cause by a leak from the heater core or coolant hoses in your heater. Usually this fogs up the interior glass as well as leaving a slimy film. This can leave your cooling system low on coolant decreasing the output from your heater.

How long does a heater matrix last?

Matrix can last many years (10+).

Can you bypass a heater core?

You basically take the two hoses off the heater core, you stick them together and you’re done. That way, the coolant will continue to circulate, even though it no longer goes through the heater core. And bypassing the heater core should have no effect at all on the performance of the engine, Charles.
