This Porsche coolant distributor tube / return line (OEM 99710675103, also replaces 99710675104) is a genuine used part for flat-six engines. It routes coolant back from the distribution block to the radiator or expansion tank. A cracked or clogged tube can cause coolant leaks, overheating, or low-coolant warnings. On these H6 engines—2.7L through 3.8L, both naturally aspirated and turbocharged—this metal or plastic line must be intact for proper cooling system function.
