This genuine OEM Audi coolant hose (4K1121071C) is a used part, removed from a donor vehicle. It also replaces 4K1121071B. Also called a coolant line or pipe, it routes engine coolant between components in the cooling system on 2.9L and 3.0L V6 MHEV turbocharged engines (EA839 family). A cracked or leaking hose can cause coolant loss, overheating, or low-coolant warnings.
