A used genuine OEM Audi/Volkswagen radiator, part number 5K0121251J, also replaces 1K0121251L and 1K0121253L. This is the main engine cooling component for 2.0L TDI diesel and 2.0L TSI/TFSI gas engines, including turbocharged and naturally aspirated variants across Audi and Volkswagen models. When the radiator fails, common symptoms include engine overheating, visible coolant leaks, or a drop in the expansion tank level.
