Detailed Description

Dayco 72010 is a radiator coolant hose engineered for specific cooling system routes where a curved hose shape is required. The EPDM material is suited for coolant exposure, while the 1 1/4 in. end diameters support the listed applications across Audi and Volkswagen models. This part number, 72010, is used in lower and upper hose positions depending on the vehicle and engine layout, including lower tee-to-engine, lower thermostat-to-tee, lower connector-to-engine, lower tee-to-water-pump, and upper engine-to-tee locations.

This part cross-references Duralast B72010 for the same application.

What It Helps Address

• Cracked or split coolant hose sections
• Coolant leaks at curved hose routing points
• Softening or swelling from age and heat cycling
• Restricted coolant flow caused by hose deterioration
• Incorrect hose shape when replacing a molded cooling hose

Installation Notes and Tips

Verify the hose routing, end diameters, and connection points before installation. This hose does not include a heat shield or protective sleeve, so inspect nearby components for abrasion or heat exposure during service. Confirm the vehicle’s exact cooling-system layout, especially on Audi lower hose applications and Volkswagen models noted without Quick Connect.

Quality Assurance

Dayco 72010 is manufactured to SAE J20R4 Class D-1 and SAE J1684 Type EC specifications for radiator coolant hose applications. The Dayco Curved Radiator Hose line is built for application-specific cooling system replacement where correct shape and material matter.
