This used OEM Heater Core Coolant Hose / Line (supply) from a Volkswagen Passat — part number 8D0819371BB — carries coolant from the engine to the heater core, supplying warm air to the cabin. It fits the 2.8L 2771CC V6 GAS DOHC naturally aspirated engine. Also known as the heater core coolant supply line, it routes antifreeze under the hood. Over time, the rubber can crack or the plastic connectors may become brittle, leading to coolant leaks and reduced cabin heat. Genuine OEM construction ensures correct fit and material resistance to heat and pressure.
