Product Details

Dayco Curved Radiator Hose 72847 is part of Dayco’s radiator hose line, which focuses on application-specific hose shapes and dimensions for cooling-system service. This lower hose is designed around the listed Chevrolet Sonic fitment and uses a dual inside diameter configuration to match the connection points in the vehicle’s coolant circuit. The EPDM material is commonly used in radiator hose applications because it is suited to hot coolant exposure and everyday underhood conditions.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Cooling-System Issues It Can Address

  • Cracked or split lower radiator hose
  • Coolant seepage at hose connections
  • Softening, swelling, or deterioration from heat and age
  • Incorrect hose routing after prior repair work
  • Restricted coolant flow caused by a damaged hose

Installation Notes and Tips

Verify the lower hose routing and diameter match before installation on 2012-2018 Chevrolet Sonic models. Inspect the mating necks, clamps, and surrounding cooling components for wear or corrosion before transferring the hose into service. After installation, refill the cooling system with the correct coolant and check for leaks at operating temperature.

Quality Assurance

This Dayco radiator coolant hose is manufactured to meet SAE J20R4 Class D-1 and SAE J1684 Type EC specifications, supporting consistent material and dimensional requirements for the listed application.
