Product Details

This Dayco Curved Radiator Hose line is engineered for direct-fit cooling system service where the upper hose must follow a formed bend and maintain consistent coolant flow. Part number 71476 uses EPDM material for resistance to heat and coolant exposure, and its 1 13/16 in. end diameters match the specified radiator and engine connections. It is a practical replacement for Chevrolet C1500, C2500, C3500, K1500, K2500, K3500, Blazer, Tahoe, and GMC C1500, C2500, C3500, K1500, K2500, K3500, Jimmy, and Yukon applications listed below. This part cross-references Gates 21770 and NAPA 8460 for the same application.

What It Helps Address

• Cracked or hardened upper radiator hose material
• Coolant leaks at the hose connection points
• Incorrect hose shape or routing on the upper cooling circuit
• Softening, swelling, or deterioration from age and heat
• Restricted coolant transfer caused by a failing hose

Installation Notes and Tips

Verify hose routing, end diameter, and position before installation. This upper radiator hose is listed for the upper location only and does not include a heat shield or protective sleeve. Inspect the radiator neck, engine fitting, and clamps for wear or corrosion before installing the new hose. Confirm the hose follows the original curved path without kinks or twist.

Quality Assurance

Dayco manufactures this hose to meet SAE J20R4 Class D-1 and SAE J1684 Type EC requirements for radiator coolant hose service. The EPDM construction and formed profile support consistent fitment on the specified Chevrolet and GMC upper radiator hose applications.
