Detailed Description

This radiator coolant hose is engineered for vehicles that use a curved hose path between the engine and radiator or coolant circuit. The EPDM rubber construction is suited for hot coolant exposure, while the formed shape helps maintain the intended routing in the engine bay. Dayco 71886 is a practical replacement choice for service work on Kia Sorento, Hyundai Santa Fe, Mitsubishi Eclipse, Mitsubishi Galant, Oldsmobile Intrigue, and select Chrysler applications where the listed hose dimensions and position match.

This part cross-references ACDelco 20307S and Gates 22070 for the same application.

Installation Notes and Tips

Verify the hose position, end inside diameter, and curved routing before installation. Match the lower or upper application exactly to the vehicle listing, and inspect adjoining clamps, necks, and coolant passages for wear or corrosion before refilling the system. Confirm that the hose follows the original path without twisting so the formed shape seats correctly.
