Used Volkswagen coolant reservoir tank bottle OEM part number 5QM121407B. This genuine used part replaces several earlier versions including 5Q0121407D, 5Q0121407S, and 5Q0121407F. It serves the 1.4L turbocharged and 3.6L V6 engines, plus the battery-electric EV models. A cracked or leaking coolant reservoir will cause low coolant warnings and potential overheating, so this tank keeps the cooling system properly pressurized and filled.
