Detailed Description

Dayco 71267 is a curved radiator coolant hose designed for vehicles that use a formed upper or lower hose with different end diameters.

This hose is listed across multiple applications, including 2004 Ford Focus upper, 1987-1991 Toyota Camry lower, and 1987-1990 Chevrolet Celebrity upper.
