Key Features

• Black finish for a clean OE-style appearance

Product Details

This Dayco curved radiator hose is engineered for upper and lower cooling-system routing where a formed hose is required. The 70519 part number appears in applications for the Ford E-100 Econoline, E-250 Econoline, E-250 Econoline Club Wagon, E-350 Econoline, and E-350 Econoline Club Wagon, as well as Jeep Cherokee, Jeep Comanche, Jeep Wagoneer, and Dodge Charger and Monaco models. For shoppers searching for a Dayco 70519 radiator hose, this part provides the correct curved shape and hose sizing for listed vehicles.

Dayco’s Curved Radiator Hose line focuses on formed coolant hoses that follow factory routing and maintain proper connection points in the cooling system. That makes this hose a practical choice when replacing a worn upper radiator hose on a Ford E-350 Econoline Club Wagon or a lower hose on a Jeep Cherokee, depending on the exact application listed below.

This part cross-references Motorcraft KM967 and Duralast C70519 for the same application.

What It Helps Address

• Cracked or hardened radiator hose material
• Coolant leaks at the hose body or ends
• Improper hose routing from a collapsed or misshaped hose
• Cooling-system service on Ford E-Series vans and Jeep/Dodge applications
• Replacement of a hose that no longer holds a secure fit at 1 1/2-inch connections

Installation Notes and Tips

• Verify upper or lower hose position before ordering; this part is listed for both positions depending on vehicle.
• Confirm the 1 1/2-inch inside diameter matches the vehicle’s radiator and engine connections.
• Check whether the vehicle is equipped with air conditioning, since some listed Jeep and Dodge applications vary by A/C configuration.
• Inspect clamps, necks, and adjacent cooling components during replacement.
• Follow the vehicle service manual for coolant refill and bleed procedures after installation.

Quality Assurance

Dayco 70519 is manufactured to meet SAE J20R4 Class D-1 and SAE J1684 Type EC requirements, supporting consistent material and performance standards for radiator hose service.
