2016-2022 Volkswagen Beetle/Passat Heater Core 561819031C

Volkswagen Heater Core OEM 561819031C is a used genuine part, originally removed from a donor vehicle. This heater core, also known as the cabin heater core, supplies warm air to the passenger compartment by circulating engine coolant through its fins. It supersedes part numbers 561819031B and 561819031A. A failing heater core often causes insufficient cabin heat, a sweet coolant odor inside, or fogged windows that won't clear. This unit was sourced from a VW Beetle or Passat equipped with 1.8T, 2.0T, 2.5, or 3.6L engines. Installation requires professional attention to avoid coolant system issues.
