Detailed Description

This Dorman coolant outlet is engineered for vehicles that use a coolant manifold layout, including applications such as the Audi TT, Audi A3, TT Quattro, and Volkswagen Eos, GTI, Jetta, Passat, and Golf. The housing features a 1.034-inch inside diameter, a 1.425-inch outlet diameter, seven outlets, and three mounting holes with a 2.32-inch bolt-hole center spacing. The black plastic body is shaped to match the original configuration and help maintain proper coolant passage alignment.
