Detailed Product Description

The Dayco Curved Radiator Hose 71546 is engineered to maintain efficient coolant circulation within the radiator system of Toyota Paseo and Tercel vehicles. Its EPDM construction offers resistance to heat, ozone, and coolant chemicals, which helps extend hose life and maintain system integrity. Both ends of the hose have an inside diameter of 1 1/16 inches, ensuring a secure connection to the radiator and engine fittings. This single inside diameter hose does not include a heat shield or protective sleeve, reflecting its design for standard cooling system applications without additional insulation requirements.

The Curved Radiator Hose product line from Dayco focuses on delivering hoses shaped to fit specific vehicle cooling system layouts, reducing installation complexity and improving coolant flow efficiency. This hose’s curved profile is optimized for the Toyota Paseo and Tercel, supporting proper coolant routing and minimizing stress on connections.
