Dayco 72384 Radiator Coolant Hose - Lower

Dayco 72384 Curved Radiator Hose Overview

Dayco 72384 is a curved radiator coolant hose built for lower cooling-system routing on select Ford and Mercury applications. Made from EPDM and finished in black, this radiator hose is shaped to match the vehicle’s hose path while maintaining a 1 1/2 in. inside diameter at both ends.

Compatible With 2006-2010 Ford Explorer, lower; 2007-2010 Ford Explorer Sport Trac, lower; and 2006-2010 Mercury Mountaineer, lower. If you are replacing a worn lower radiator hose on these vehicles, Dayco 72384 provides the correct curved layout for the application.

Key Features

• EPDM construction for cooling-system hose service
• Curved radiator hose design for lower hose routing
• 1 1/2 in. inside diameter at both ends
• Black finish for a clean OE-style appearance
• Meets SAE J20R4 Class D-1 and SAE J1684 Type EC specifications
• Dayco Curved Radiator Hose line for application-specific cooling fitment

Detailed Product Description

The Dayco Curved Radiator Hose line is engineered for vehicles that require a formed hose shape rather than a straight universal replacement. Part number 72384 is a single I.D. hose with equal 1 1/2 in. end diameters and a 22 1/2 in. trunk height, making it suitable for lower radiator hose routing where bend geometry matters. This hose is listed for Ford Explorer, Ford Explorer Sport Trac, and Mercury Mountaineer applications from 2006 through 2010, and it cross-references Ford 6L2Z-8260-B for the same application.

Dayco 72384 is a direct-fit style radiator coolant hose for owners replacing a deteriorated lower hose on the Explorer, Explorer Sport Trac, or Mountaineer. The EPDM material is selected for coolant-system use, and the hose is specified without a heat shield or protective sleeve.

Common Problems This Hose Can Address

• Coolant leaks from a cracked or aged lower radiator hose
• Softening, swelling, or collapse of the original hose
• Improper hose routing after a previous replacement
• Loss of cooling-system integrity from hose deterioration
• Fitment issues caused by using a straight hose in a curved application

Installation Notes and Tips

Verify the hose routing and end diameters before installation. Drain the cooling system as needed, inspect the radiator neck and engine-side connection points, and replace any damaged clamps or corroded fittings during service. Confirm the hose follows the original lower hose path on the 2006-2010 Ford Explorer, 2007-2010 Ford Explorer Sport Trac, or 2006-2010 Mercury Mountaineer before refilling the system.

Quality Assurance

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