About the Molded Coolant Hose Product Line
The Molded Coolant Hose line by Gates focuses on delivering hoses that are pre-formed to exact specifications, eliminating the need for bending or shaping during installation. This product line enhances installation accuracy and reduces the risk of leaks or hose damage. The 22581 part benefits from this molded design, ensuring a precise fit for the cooling system of Mercedes-Benz ML55 AMG, ML320, ML350, ML430, and ML500 vehicles.
Detailed Product Description
The Gates Molded Coolant Hose 22581 is manufactured from EPDM, a synthetic rubber known for its excellent resistance to heat, ozone, and automotive fluids. The hose features two different inside diameters—1.38 inches (35 mm) on one end and 1.62 inches (41 mm) on the other—allowing it to connect seamlessly between components with varying sizes. With a centerline length of 16.3 inches (414 mm), this molded hose fits precisely within the engine bay layout of compatible Mercedes-Benz ML-Class models. The absence of an internal spring reduces the risk of hose collapse or failure under pressure, contributing to long-term durability.
