Overview

Dayco 72973 is a curved radiator coolant hose built for lower cooling-system routing and direct replacement applications. It uses EPDM construction with a protective sleeve and is shaped to follow the factory hose path for Ram truck fitments.

Key Features

  • EPDM rubber construction for coolant-system service
  • Curved hose profile for lower radiator routing
  • Protective sleeve included for added abrasion resistance
  • Dual I.D. hose design with SAE J20R4 Class D-1 and SAE J1684 Type EC specifications
  • Black finish for a factory-style appearance

Detailed Description

This Dayco radiator coolant hose is engineered as a curved replacement for lower cooling-system connections. The dual inside diameter design and molded shape support proper routing where a formed hose is required, while the EPDM material is suited for coolant exposure and everyday engine-bay temperatures. Fits 2013-2018 Ram 1500, lower, and fits 2019-2021 Ram 1500 Classic, lower. Dayco 72973 is a practical choice when replacing a worn or damaged lower radiator hose on Ram 1500 and Ram 1500 Classic trucks.

Common Uses

  • Replacing a cracked or softened lower radiator hose
  • Restoring coolant flow after hose swelling or leakage
  • Addressing hose routing issues caused by a collapsed or misshaped hose
  • Repairing cooling-system service concerns on Ram 1500 and Ram 1500 Classic applications

Installation Notes

Verify hose routing, end diameters, and lower-position fitment before installation. Inspect adjoining fittings and clamps for wear, and confirm the hose follows the original curved path without twisting. Match the application to the listed Ram 1500 and Ram 1500 Classic fitments for proper installation.
