This genuine Porsche coolant return pipe, OEM 99610665203 (also replaces 99610665202), is a used line removed from a donor Boxster. It serves the return coolant circuit in the 2.5L, 2.7L, and 3.2L H6 engines (note these are the M96 series). Over time, the plastic tube can become brittle and crack, or the O-ring seals degrade, causing a slow coolant leak that may lead to overheating if ignored.
