Product Details

This Dayco curved radiator hose is engineered for lower radiator hose routing where a branched hose layout is required. The EPDM material is commonly used in coolant applications for its resistance to heat and coolant exposure, while the molded shape helps match the factory routing on vehicles such as the Ford Crown Victoria, Lincoln Town Car, and Mercury Grand Marquis. Part number 71561 is also referenced in the aftermarket under cross numbers including Duralast E71561.

Compatible vehicle applications include Fits 1995-1997 Ford Crown Victoria, Lower; Fits 1996-1997 Lincoln Town Car, Lower; Fits 1995-1997 Mercury Grand Marquis, Lower; Fits 1992-1994 Ford Crown Victoria, Lower; Fits 1994 Mercury Grand Marquis, Lower; Fits 1992 Mercury Grand Marquis, Lower; and Fits 1993 Mercury Grand Marquis, Lower, Exc. Late Police Car. Dayco 71561 is a direct-fit style option for lower radiator hose replacement on these applications.

Common Repair Uses

  • Replacing a cracked or split lower radiator hose
  • Restoring coolant circulation in the radiator circuit
  • Addressing coolant leaks at molded hose bends or branch points
  • Correcting hose collapse, swelling, or soft spots from age and heat
  • Servicing OE-style lower hose routing on Ford Crown Victoria, Lincoln Town Car, and Mercury Grand Marquis models

Installation Notes

Verify hose routing, end diameters, and vehicle configuration before installation. This hose does not include a heat shield or protective sleeve. Confirm the application is for lower position use and note the fitment exclusion for 1993 Mercury Grand Marquis late police car models. Inspect clamps, necks, and adjacent cooling components during replacement to help ensure a proper seal.

Quality Assurance

Dayco manufactures cooling-system hoses to published SAE specifications, including SAE J20R4 Class D-1 and SAE J1684 Type EC, for consistent material and dimensional standards.
