Land Rover Part Number: LR017030 - Heater Matrix Assembly
LR017030 is a Heater Matrix Assembly. Fitted into the front heater and air conditioning housing, it transfers heat from engine coolant into the cabin airflow: warm coolant passes through the matrix's small-bore tubes while vehicle air flows across the tube-and-fin core. The complete LR017030 assembly includes inlet and outlet coolant pipes for direct connection to the vehicle circuit, simplifying replacement when the entire heater core and pipework are changed together. Failure of the heater matrix can allow coolant to enter the HVAC airflow or cause loss of cabin heat, so replacement restores correct coolant containment and heat transfer performance. Designed for Discovery 3 and Range Rover Sport L320 models fitted with air conditioning, the assembly fits into the front HVAC housing on the vehicles specified below.

Frequently Asked Questions
The LR017030 heater matrix transfers heat from the engine coolant into the cabin by routing warm coolant through a tube-and-fin core while cabin air passes over it. The complete assembly includes inlet and outlet pipes for connection to the vehicle coolant circuit, so replacement commonly involves changing the heater core and associated pipework together. Common failure signs are loss of cabin heat or coolant entering the HVAC airflow.
