  • Single I.D. hose with 1 9/32 in. inside diameter at both ends
  • Protective sleeve included; heat shield not included
  • Built to SAE J20R4 Class D-1 and SAE J1684 Type EC specifications
  • Dayco part number 72889 for direct application lookup

Curved Radiator Hose Details

Dayco’s Curved Radiator Hose line is built for formed cooling-system routing where a straight hose will not match the factory path. This Dayco 72889 hose follows the upper radiator hose layout used on 2012-2013 Chevrolet Impala and 2014-2016 Chevrolet Impala Limited models, helping maintain proper coolant flow and a secure fit at the connection points. The hose measures 18 1/2 in. in trunk height and has matching end dimensions of 1 9/32 in. inside diameter and 1 21/32 in. outside diameter.

Compatible With 2012-2013 Chevrolet Impala, upper. Compatible With 2014-2016 Chevrolet Impala Limited, upper. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

  • Upper radiator hose cracking or splitting
  • Coolant seepage at the hose connection points
  • Collapsed or softened hose material from age and heat
  • Incorrect hose shape that does not follow the factory routing
  • Cooling-system service on Chevrolet Impala and Impala Limited models

Installation Notes

Verify the upper hose routing, end diameters, and formed shape against the original part before installation. Inspect the radiator neck and engine-side connection surfaces for corrosion, residue, or damage, and replace worn clamps as needed. Confirm that the protective sleeve is positioned to match the original heat-exposed routing.

Quality Assurance

Dayco manufactures this hose to meet SAE J20R4 Class D-1 and SAE J1684 Type EC requirements for radiator coolant hose applications.
