Product Details

This Dayco Curved Radiator Hose is part of Dayco’s Curved Radiator Hose line, which focuses on formed coolant hoses for specific vehicle routing and fitment needs. For 1995-1999 Mitsubishi Eclipse lower radiator hose applications, the molded shape helps match the original hose path and connection points. The Dayco 72428 is cross-referenced by ACDelco 24313L and Gates 22113 for the same application.

Common Cooling System Issues

• Cracked or hardened lower radiator hose
• Coolant leaks at hose connection points
• Restricted coolant flow from a deteriorated hose
• Soft spots, swelling, or hose collapse under heat and pressure
• Service replacement after age-related EPDM wear

Installation Notes

Verify the lower hose routing, end diameters, and vehicle application before installation. Inspect the radiator neck and engine-side connection surfaces for corrosion, residue, or damage, and replace clamps if they do not secure properly. Confirm the hose is seated fully and routed without twisting so the cooling system can maintain proper flow.

Quality Assurance

This hose is manufactured to SAE J20R4 Class D-1 and SAE J1684 Type EC standards, supporting material and performance requirements for coolant hose service. Dayco 72428 is a direct-fit replacement for listed Mitsubishi Eclipse applications.
