Detailed Product Description

The Gates 20801 radiator coolant hose is molded from EPDM, a synthetic rubber known for its excellent resistance to heat, ozone, and automotive fluids. The hose features two different inside diameters—1.26 inches (32 mm) on one end and 1.5 inches (38 mm) on the other—allowing it to connect seamlessly between varying radiator and engine fittings. With a centerline length of 12.7 inches (323 mm), this hose is designed to fit the cooling systems of BMW 320i and M3 models, Toyota 4Runner and Pickup trucks, as well as the Saturn Vue. The absence of an internal spring ensures unobstructed coolant flow, reducing the risk of blockages or pressure points.
