A used Audi Heater Core Coolant Hose Set, OEM part number 8K1819350AT, is a genuine factory hose assembly. This set also replaces numbers 8KD819373 and 8K1819373AN. Designed for 1.8L and 2.0L turbocharged engines, it routes coolant to and from the heater core. A failing set can cause coolant leaks, interior fogging, reduced cabin heat, or engine overheating. Proper flow is essential for consistent climate control. This used OEM part was removed from a donor vehicle and is ready for installation.
