UTP1725 - Heater Matrix
Heater Matrix in the HVAC heater assembly of the Defender 90/110.
The heater matrix is the heat-exchange core inside the heater box, through which hot engine coolant circulates to warm the air blown into the cabin. This unit is designed for non-air-conditioned models with horizontal inlet and outlet pipe connections, up to VIN WA159806 and for RHD vehicles from VIN XA159807 to 2A633474.
A failed or leaking heater matrix typically results in loss of cabin heat, a sweet coolant smell inside the vehicle, or misting of the windscreen from the inside. Replacement requires removal of the heater box from the dashboard.
