This used genuine OEM radiator (8E0121251AJ) was removed from an Audi S4 donor vehicle. Designed for the 4.2L 4163CC V8 gas engine, the radiator dissipates heat from the coolant to prevent overheating. When failing, telltale signs include coolant leaks, visible damage to the core or tanks, and elevated engine temperatures.
