Detailed Description

Dayco 81411 is a radiator coolant hose used in the lower position on the specified applications. It fits 1959-1960 Lincoln Continental, lower, and 1957 Pontiac Bonneville, lower, with the Bonneville note indicating vehicles without air conditioning. For buyers searching for a 1959-1960 Lincoln Continental lower radiator hose or a 1957 Pontiac Bonneville lower coolant hose, this part number provides a direct match to the listed applications. The Dayco Flex Radiator Hose line is used in cooling-system service where a formed replacement hose is needed for proper coolant routing.

What It Helps Address

  • Softening, swelling, or collapse in an aging coolant hose
  • Restricted coolant flow caused by hose deterioration
  • Loss of cooling-system integrity on listed classic vehicles

Installation Notes and Tips

Verify the vehicle year, make, model, and lower hose position before installation. On the 1957 Pontiac Bonneville, confirm the no-air-conditioning application note. Inspect hose clamps, necks, and adjacent cooling-system components for wear before replacing the hose.
