Key Features

• EPDM rubber construction for coolant-system service
• Curved hose profile for formed routing
• Single I.D. hose design with 1 5/16 in. inside diameter at both ends
• Black finish with SAE J20R4 Class D-1 and SAE J1684 Type EC specification support
• No heat shield or protective sleeve included

Detailed Description

This Dayco radiator coolant hose is engineered as a formed replacement for lower cooling-system routing where a curved hose shape is required. The EPDM material is selected for radiator hose service, while the matched end diameters help maintain consistent coolant passage through the hose assembly. Fits 2010-2017 Chevrolet Equinox, lower, and fits 2010-2017 GMC Terrain, lower. Part number 72526 is also referenced in aftermarket catalogs under cross numbers such as Gates 23730 and Duralast E72526 for the same application.

Common Uses

• Replacing a cracked or softened lower radiator hose
• Restoring coolant circulation through a formed hose route
• Addressing coolant seepage at hose ends
• Correcting hose collapse, swelling, or heat-related wear

Installation Notes

Verify hose routing, end diameters, and formed shape before installation. Inspect clamps, necks, and adjoining cooling-system components for wear or corrosion before reassembly. Confirm fitment against the vehicle application list for the Chevrolet Equinox or GMC Terrain before service.

Quality Assurance

This hose is built to SAE J20R4 Class D-1 and SAE J1684 Type EC specifications for radiator hose service.
