Product Details

This Dayco Curved Radiator Hose is engineered for upper radiator connections on 1995-1996 Ford E-150 Econoline, E-150 Econoline Club Wagon, E-250 Econoline, E-350 Econoline, and E-350 Econoline Club Wagon models. The EPDM rubber construction is suited for coolant circulation service, while the curved shape supports the factory hose path in the engine bay. The 10-inch trunk height and matched end diameters help maintain proper routing and fitment for the listed Ford E-Series applications. Part number 71828 is a practical replacement choice when servicing the upper radiator hose on these vans.

Common Replacement Reasons

• Cracked or split upper radiator hose
• Coolant seepage at the hose body or ends
• Softening, swelling, or hose collapse
• Restricted coolant flow from aged hose material
• Loss of proper hose shape in the engine bay

Installation Notes

Verify the hose routing, end diameters, and upper-position application before installation. Inspect the radiator neck, engine connection points, and clamps for wear or corrosion, and replace damaged sealing surfaces as needed. Confirm that the hose follows the original curved path without twisting so the cooling system maintains proper alignment.
