Audi coolant/heater core return line/pipe with OEM part number 7L0819926AJ is a used genuine component. Also known as the heater core return line or coolant pipe, this part routes coolant back from the heater core to the engine. On 3.2L and 3.6L V6 engines (EA390 family), a cracked or leaking return line often causes low cabin heat or visible coolant puddles under the dash. Made from metal or reinforced plastic, it’s a direct bolt-on replacement for Audi Q7, Porsche Cayenne, and Volkswagen Touareg applications.
