This Volkswagen coolant reservoir hose (OEM 5C0121109B) is a used genuine line that routes coolant to and from the expansion tank on 2.5-liter inline-five engines found in Beetle, Jetta, and Passat models. Also called the coolant reservoir line, it carries pressurized coolant and can develop cracks or leaks over time, leading to low coolant levels or overheating. A failing hose may show visible drips, cause a soft or collapsed hose, or trigger a low-coolant warning.
