The trunk height of 16 1/2 inches allows for proper routing and fitment in the engine bay.

The Curved Radiator Hose product line by Dayco focuses on delivering hoses that accommodate specific vehicle cooling system geometries, such as bends and curves, to optimize coolant flow and installation ease. This hose is part of that line, designed to fit the contours of the Toyota RAV4 cooling system precisely.
