Product Details

Dayco’s Curved Radiator Hose line focuses on formed coolant hoses that match the routing and connection points required by the vehicle’s cooling system. This hose is shaped for the upper radiator position on Toyota Tacoma trucks and uses EPDM material to handle coolant exposure in normal service. If you are replacing a worn, cracked, or softened upper hose, Dayco 72410 provides the correct formed profile and end sizing for the application.

This part cross-references Toyota 16571-0C120 for the same application.

Common Cooling System Issues It Can Address

• Cracked or split upper radiator hose
• Coolant seepage at the hose connection points
• Softening or swelling from age and heat cycling
• Incorrect hose shape after a previous repair
• Restricted coolant flow caused by a deteriorated hose

Installation Notes and Tips

Verify the hose routing, end diameters, and upper-position fitment before installation. Inspect the radiator neck, engine-side connection, and clamps for wear or corrosion, and replace damaged clamps as needed. After installation, refill the cooling system with the correct coolant and check for leaks once the engine reaches operating temperature.

Quality Assurance

This hose is manufactured to SAE J20R4 Class D-1 and SAE J1684 Type EC standards for coolant hose performance. It is a direct-fit replacement for 2005-2023 Toyota Tacoma upper radiator hose applications and is identified by part number 72410.
