The Audi Coolant Hose / Line 4G0121056L is a used OEM part, also superseding 4G0121056G. This genuine coolant hose was removed from an A6 or A7 Quattro equipped with either a 3.0L V6 TDI turbo diesel or a 3.0L V6 supercharged gasoline engine. Its job is to carry coolant between engine components, maintaining proper operating temperature. A failing coolant hose often develops cracks or leaks, leading to low coolant levels and potential overheating. Inspect the hose for swelling or brittleness before installation.
