Diagram ref no 13

The heater matrix (often referred to as a heater core or heat exchanger) functions like a small radiator located inside the vehicle’s climate control unit. It transfers heat from the engine’s coolant into the cabin airflow. When hot coolant flows through the core’s tubes and fins, air blown across the matrix by the blower motor warms up before entering the passenger compartments, providing comfortable cabin heating even in cold conditions.

Designed and manufactured to strict MAHLE quality standards, this heater matrix delivers reliable heat transfer, long service life, and consistent HVAC performance. It restores proper cabin heating and overall climate control performance when the original OE heater core has failed, become clogged, or begun to leak.

Fitment / Position on Car
•   Installed in: HVAC housing behind the dashboard
•   Location: Integrated into the climate control module where air streams from the blower fan pass through before distribution
•   Interface: Works with coolant inlet/outlet hoses, blend doors, actuators, and air plenums to channel conditioned air to multiple zones
