Product Details

Dayco 71929 is a lower radiator coolant hose shaped to follow the routing used in select Ford, Suzuki, and Toyota cooling systems. The curved profile helps match the factory hose path, while the EPDM rubber construction is suited for hot coolant exposure and everyday engine bay conditions. If you are replacing a lower hose on a 2012-2015 Ford Edge, a 2004-2006 Suzuki XL-7, or a 1996-2002 Toyota 4Runner, this hose provides the correct style and dimensions for those listed applications. Cross-reference part numbers include Gates 21534 and NAPA 8249 for the same application.

Common Replacement Reasons

• Cracked or split lower radiator hose
• Coolant seepage at the hose body or ends
• Softening, swelling, or collapse under heat
• Restricted coolant flow from hose deterioration
• Maintenance replacement during cooling-system service

Installation Notes

Verify the hose routing, end diameters, and lower-position fitment before installation. Inspect the hose necks, clamps, and adjoining cooling-system components for wear or corrosion before reassembly. Confirm the hose is seated fully and routed without kinks so coolant flow remains unobstructed.

Quality Assurance

This Dayco radiator hose is manufactured to SAE J20R4 Class D-1 and SAE J1684 Type EC requirements, supporting consistent material and performance standards for cooling-system replacement service.
