The dual inside diameter ends, measuring 1 1/4 inch and 1 1/2 inch respectively, allow for compatibility with different radiator and engine fittings, making it suitable for various vehicle models such as the BMW 190E and M3, Chevrolet S10 and S10 Blazer, Chrysler 300E and 300SE, Ford Escort and Taurus, GMC S15, Jeep Cherokee, Mercedes-Benz 300SEL and 300SL, Mercury Sable and Topaz, and Porsche 944 and 968.

The Curved Radiator Hose product line from Dayco focuses on providing hoses with precise bends and dual diameter ends to accommodate specific vehicle cooling system layouts. This hose does not include a heat shield or protective sleeve, which is typical for applications where additional protection is not required. Its compliance with SAE J20R4 Class D-1 and SAE J1684 Type EC standards ensures it meets industry requirements for coolant hoses.
