Installation Notes and Tips

Verify the vehicle’s HVAC configuration before ordering, especially on 2012 BMW 328i xDrive models noted as not compatible with Automatic Temperature Control. Confirm the part number HT400014C against the original heater core and inspect the cooling system for contamination or leaks before installation. On BMW 128i, 135i, 328i, 335i, and X1 service jobs, access to the heater core typically requires substantial HVAC disassembly, so compare the replacement part to the removed unit before reassembly.
