Detailed Description

This radiator coolant hose is engineered for upper cooling-system connections where a curved shape is needed to match factory routing. The EPDM rubber construction is suited for coolant exposure and underhood temperatures, while the protective sleeve adds an extra layer where the hose may contact nearby components. With a 1 1/2 inch inside diameter at each end, the Dayco 72573 supports a consistent connection at the radiator and engine-side attachment points.

Dayco 72573 also cross-references ACDelco 20543S and Gates 23608 for the same application.

Common Cooling-System Issues It Can Address

• Cracked or hardened upper radiator hose material

• Collapsed or softened hose sections from age and heat
• Incorrect hose routing after a previous replacement
• Restricted coolant flow caused by a deteriorated hose

Installation Notes and Tips

Verify upper hose routing before installation and compare the hose shape to the original part. Inspect the radiator neck, engine outlet, and clamps for wear or corrosion before installing the new hose. Confirm the 1 1/2 inch inside diameter and application match the vehicle before service.

Quality Assurance

This Dayco radiator hose is built to SAE J20R4 Class D-1 and SAE J1684 Type EC specifications, supporting standardized cooling-system material and performance requirements. The protective sleeve adds durability in areas where the hose may be exposed to abrasion.
