Dayco 72056 Radiator Coolant Hose - Lower or Upper

Curved Radiator Hose for Suzuki and Chevrolet Applications

Dayco 72056 is a curved radiator coolant hose built for specific upper and lower cooling system routes on select Suzuki and Chevrolet vehicles. Made from EPDM rubber and finished in black, it is shaped for direct coolant transfer in applications that require a 1 5/16 in. inside diameter at both ends.

The Dayco Curved Radiator Hose line focuses on formed hose routing for vehicles with tight engine-bay layouts. This hose follows the original curved path needed for proper coolant flow in the Suzuki Grand Vitara, Suzuki Vitara, Suzuki XL-7, and Chevrolet Tracker applications listed below.

Detailed Product Overview

This radiator hose is designed for cooling system routing where a formed, curved hose is required to connect the engine and radiator circuit. The EPDM material is commonly used in coolant hose applications because it is suited to heat and coolant exposure in everyday driving conditions. Dayco 72056 is a direct-fit style replacement for the specified upper and lower hose positions on select Suzuki Grand Vitara, Suzuki Vitara, Suzuki XL-7, and Chevrolet Tracker models.

This part cross-references Gates 23157 for the same application. It also cross-references Duralast D72056 for the same application.

• Incorrect hose routing on a replacement cooling system repair
• Fitment issues when replacing a curved upper or lower radiator hose

Installation Notes and Tips

Verify the hose position before installation, since this part is used in both upper and lower applications depending on the vehicle. Confirm the 1 5/16 in. end inside diameter matches the original hose and inspect adjoining clamps, necks, and coolant passages for wear or corrosion before reassembly. After installation, refill the cooling system with the correct coolant and check for leaks at operating temperature.
