Dayco 71824 Radiator Coolant Hose - Lower

Dayco 71824 Curved Radiator Hose Overview

The Dayco 71824 curved radiator hose is a lower coolant hose built for direct-fit service on select 1995 Ford Ranger and 1995 Mazda B3000 applications. Made from EPDM rubber with a black finish, it is shaped to route coolant cleanly through the engine bay while maintaining a secure connection at both ends.

Dayco’s Curved Radiator Hose line focuses on molded hose geometry for vehicles that need a specific bend and length. This Dayco 71824 hose follows that approach with a single I.D. hose design, a protective sleeve, and SAE J20R4 Class D-1 / SAE J1684 Type EC compliance for cooling-system service.

Key Features

• EPDM construction for cooling-system durability
• Curved lower radiator hose design for proper routing
• 1 7/16 in. inside diameter at both ends
• Protective sleeve included for added abrasion resistance
• Black finish for a clean OE-style appearance
• Built to SAE J20R4 Class D-1 and SAE J1684 Type EC specifications

Detailed Description

Dayco 71824 is a radiator coolant hose for lower-position applications on the 1995 Ford Ranger and 1995 Mazda B3000. The molded curved shape helps the hose follow the factory coolant path, while the EPDM rubber construction is suited for hot coolant exposure and everyday engine-bay conditions. If you are replacing a worn lower radiator hose on a Ford Ranger or Mazda B3000, this part number provides a direct replacement option with the correct end diameters and hose profile.

This part cross-references Motorcraft KM2978 and Duralast C71824 for the same application. The Dayco 71824 part number is also useful when searching for a lower radiator hose for 1995 Ford Ranger or 1995 Mazda B3000 cooling-system repair.

What It Helps Address

• Coolant leaks from a cracked or aged lower radiator hose
• Softening, swelling, or collapse of the original hose
• Improper hose routing after a cooling-system repair
• Loss of coolant flow caused by a damaged hose path
• Visible wear at the hose ends or along the bend area

Installation Notes and Tips

Verify the hose routing, end diameters, and lower-position fitment before installation. Inspect the radiator neck and engine-side connection points for corrosion, residue, or sharp edges that can shorten hose life. Transfer the hose along the factory path so the curved section is not twisted, and confirm the protective sleeve is positioned where abrasion is most likely.
