Detailed Product Description

The Dayco Curved Radiator Hose 70984 is a dual inside diameter hose designed to meet the cooling system requirements of Dodge Dakota and Porsche 924 models.

The hose features a curved design to accommodate specific routing needs within the engine bay, with end diameters measuring 1 1/4 inch and 1 1/2 inch to match factory connections. It does not include a heat shield or protective sleeve, focusing on core functionality and fitment. Compliance with SAE J20R4 Class D-1 and SAE J1684 Type EC standards confirms its suitability for automotive coolant applications.
