038 117 070 A: Oil/water exchanger O-ring seal for Audi 80 & Coupé

This O-ring seal ensures the watertightness of the oil/water exchanger fitted to the Audi 80 and Coupé 81. As part of the restoration or maintenance of these classic vehicles, its replacement is essential as soon as signs of leakage or degradation of the original seal are detected. A failing seal can lead to fluid mixing and compromise the proper operation of both the cooling circuit and the lubrication circuit. Opting for a new part guarantees a return to original specifications for these iconic Audi models.
