Dayco 72277 Radiator Coolant Hose - Lower or Upper

Curved Radiator Hose for OE-Style Cooling Repair

Dayco 72277 is a curved radiator coolant hose built from EPDM for dependable coolant transfer in the engine cooling system. It features a black finish, a single I.D. hose design, and matching 1 9/32-inch inside diameters at both ends for a direct replacement-style fit.

The Dayco Curved Radiator Hose line focuses on application-specific hose routing and OE-style dimensions for service work on vehicles that need a formed coolant hose rather than a universal straight hose.

• Single I.D. hose design
• 1 9/32-inch inside diameter at both ends
• Built to SAE J20R4 Class D-1 and SAE J1684 Type EC specifications

Detailed Description

Dayco 72277 is a radiator coolant hose for vehicles that require a formed, curved hose to maintain proper coolant flow and routing around engine components. The EPDM rubber construction is suited for cooling-system temperatures and coolant exposure, while the molded shape helps match the original hose path. This part number is used across several applications, including Fits 2007-2009 Kia Amanti, Upper; Fits 2004-2008 Chevrolet Aveo, Lower; Fits 2006-2008 Chevrolet Aveo5, Lower; Fits 2005-2008 Pontiac Wave, Lower; Fits 2004-2008 Suzuki Swift+, Lower; and Fits 2005-2007 Pontiac Wave5, Lower. Dayco 72277 also cross-references ACDelco 24524L and Gates 22918 for the same application.

What It Helps Address

• Coolant leaks from a cracked or aged radiator hose
• Softening, swelling, or collapse in an original hose
• Improper hose routing after cooling-system service
• Loss of coolant flow caused by a damaged curved hose
• Fitment issues when a formed upper or lower hose is required

Installation Notes and Tips

Verify the hose routing, end diameters, and position before installation. This hose is used in both upper and lower radiator hose locations depending on the vehicle, so match the original routing on the Kia Amanti, Chevrolet Aveo, Chevrolet Aveo5, Pontiac Wave, Pontiac Wave5, or Suzuki Swift+ application. Inspect clamps, necks, and adjoining cooling-system components for wear before installing Dayco 72277.

Quality Assurance

Dayco manufactures this hose to SAE J20R4 Class D-1 and SAE J1684 Type EC specifications for radiator coolant hose service. The EPDM construction and application-specific shape support consistent replacement of the original curved hose on listed vehicles.
