Dayco Curved Radiator Hose 71813
Dayco 71813 is a curved radiator coolant hose built for heavy-duty cooling system service. Made from EPDM rubber with a black finish, it uses a single I.D. hose design and 2 1/2-inch inside diameters at both ends for a direct replacement style fit in the correct application.
Compatible With Ford, Freightliner, Mack, Navistar, Peterbilt, and White cooling system applications, this Dayco Curved Radiator Hose supports radiator-to-engine coolant transfer where a formed hose route is required. The Dayco Curved Radiator Hose line is focused on shaped hose routing for demanding truck and commercial vehicle cooling layouts.
Key Features
- Part number 71813
- EPDM construction for coolant hose service
- Black curved radiator hose design
- 2 1/2-inch inside diameter at both ends
- Single I.D. hose configuration
- SAE J20R4 Class D-1 and SAE J1684 Type EC specification
- No heat shield and no protective sleeve
Detailed Description
This radiator coolant hose is built for applications that require a formed, curved hose path rather than a straight universal hose. The EPDM material is commonly used in cooling system hoses for its resistance to heat and coolant exposure, while the SAE J20R4 Class D-1 and SAE J1684 Type EC specifications provide a clear standard for heavy-duty hose construction. If you are replacing a worn coolant hose on a Ford, Freightliner, or Peterbilt cooling system, 71813 offers the dimensions and hose type needed for the correct fit.
This part cross-references Duralast C71813 and Peterbilt 07-07153A for the same application.
What It Helps Address
- Coolant leaks from cracked or aged radiator hose rubber
- Softening, swelling, or collapse in a worn coolant hose
- Improper hose routing in curved cooling system layouts
- Overheating caused by restricted coolant flow through a damaged hose
- Replacement needs for heavy-duty truck radiator hose service
Installation Notes and Tips
Verify the hose route, end diameters, and formed shape before installation. Match the 2 1/2-inch inside diameter at both ends to the existing connection points, and inspect clamps, necks, and adjoining pipes for wear or corrosion before reassembly. Confirm clearance around the hose path so the curved profile is not pinched or twisted during installation.
Quality Assurance
Dayco manufactures cooling system hoses to published SAE specifications, including SAE J20R4 Class D-1 and SAE J1684 Type EC for this part. That specification-based construction helps support consistent fit and material performance in the intended heavy-duty radiator hose application.
