About the Molded Coolant Hose Product Line

The Gates Molded Coolant Hose line focuses on precision-molded radiator hoses that provide consistent coolant flow and fitment accuracy. This product line eliminates the need for multiple hose assemblies by offering a single molded piece designed to meet exact OEM specifications. The 22425 hose benefits from this approach by delivering a reliable, leak-resistant connection tailored for specific Chevrolet and GMC van models.

Detailed Product Description

This radiator coolant hose is made from EPDM, a synthetic rubber known for its resistance to heat, ozone, and automotive fluids, making it suitable for demanding engine environments. The molded construction ensures the hose maintains its shape and fit, reducing the risk of kinks or leaks. With a centerline length of 19.9 inches (505 mm), and differing inside diameters on each end (1.52 inches/39 mm and 1.77 inches/45 mm), it is engineered to match the cooling system layout of Chevrolet Express and GMC Savana vans precisely. The absence of internal springs and quick connect fittings simplifies installation and reduces potential failure points.
