Dayco 72565 Radiator Coolant Hose - Upper

Dayco Curved Radiator Hose 72565

Dayco 72565 is a curved radiator coolant hose built for upper cooling-system routing on select Honda trucks and SUVs. It uses EPDM construction and a single I.D. hose design to match the shape and connection size needed for the application.

Compatible with 2009-2015 Honda Pilot, upper, and 2009-2014 Honda Ridgeline, upper, this hose is a direct-fit cooling replacement for vehicles that need a formed upper radiator hose. The Dayco Curved Radiator Hose line is designed around application-specific bends and OE-style dimensions for straightforward service on the Honda Pilot and Honda Ridgeline.

Key Features

• EPDM rubber construction for cooling-system use
• Black finish
• Single I.D. hose design
• 1 3/16 in. inside diameter at both ends
• Curved upper radiator hose profile
• Meets SAE J20R4 Class D-1 and SAE J1684 Type EC specifications
• Dayco part number 72565 for easy identification

Detailed Description

This Dayco radiator coolant hose is shaped for upper hose routing and sized with matching 1 3/16 in. end diameters to support proper coolant transfer between engine and radiator connections. EPDM material is commonly used in cooling-system hoses because it is suited to heat and coolant exposure, while the curved form helps follow the factory hose path in the engine bay. If you are replacing a worn upper hose on a Honda Pilot or Honda Ridgeline, 72565 provides the correct formed layout for the listed applications.

This part cross-references Honda (e.g., 19501-RN0-A00, 19502-RJE-A10) for the same application.

What This Hose Helps Address

• Coolant leaks from cracked or aged upper radiator hose material
• Softening, swelling, or collapse in the cooling hose
• Improper hose routing caused by a damaged formed hose
• Loss of coolant circulation through the upper radiator connection
• Service replacement for a worn Honda Pilot or Honda Ridgeline upper hose

Installation Notes and Tips

Verify the hose routing, end diameters, and upper-position fitment before installation. Inspect hose clamps, radiator necks, and engine fittings for wear or corrosion, and replace any damaged sealing surfaces during service. Confirm the hose follows the original curved path without twisting so the cooling system maintains proper clearance and alignment.

Quality Assurance

This hose is built to SAE J20R4 Class D-1 and SAE J1684 Type EC specifications, supporting application-specific cooling-system service for the listed Honda vehicles.
