With a similar design to a vehicles radiator, a heater core (heater matrix) is designed to be installed inside the vehicles cabin. Often found under the dashboard it allows hot coolant to run from the vehicles engine into the cabin. This is often a useful item on a cold winter morning, when you require some heat to demist the windows. The heat given off from the heater core is then blown via a fan system we control on the dashboard. A leaking heater matrix often leaks straight onto the interior carpet, so if you feel a wet carpet or the vehicle constantly seems to mist up then we recommend checking this. The coolant often gives off a slight odour which helps aid in telling whether your matrix is leaking.
