Product Description and Specifications

This radiator coolant hose is engineered with EPDM rubber, known for its resistance to heat, ozone, and coolant chemicals, making it suitable for the demanding environment of an engine bay. The hose has two different inside diameters at each end—1.3 inches (33 mm) and 1.45 inches (37 mm)—to accommodate specific radiator and engine connections. With a centerline length of 19.9 inches (505 mm), it fits the Toyota Sienna cooling system layout without modification. The absence of an internal spring allows for unobstructed coolant flow, reducing the chance of blockages or pressure drops.

Common Applications and Problem Solving
