This used OEM Porsche coolant/water hose (return) — OEM part number 99610622215 — is a genuine replacement for the coolant return circuit. Also supersedes 99610622212, 99610622210, and 99610622207. Designed for the 2.7L, 3.2L, and 3.4L flat-six engines in Boxster and Cayman models, this return hose carries coolant back from the heater core or secondary system. A cracked or collapsed return hose can cause low coolant flow, visible leaks, and engine overheating — catching it early prevents head gasket damage.
