The Gates molded connector‑to‑reservoir coolant hose for 2001–2003 BMW 530i 3.0L provides the designed path between a connector and the expansion reservoir. Its molded profile supplies required bends and ports for proper flow and attachment. Replace this hose when worn or damaged to maintain coolant containment, support reservoir function, and help prevent leaks that could compromise engine temperature control.
