Detailed Product Description

The Gates Molded Coolant Hose 21219 is a radiator coolant hose designed to maintain optimal engine temperature by facilitating efficient coolant circulation. Its EPDM construction provides durability against high temperatures and exposure to automotive fluids. The hose features two different inside diameters—1.19 inches (30 mm) on one end and 1.31 inches (33 mm) on the other—allowing it to connect seamlessly between components with varying sizes. With a centerline length of 18.4 inches (467 mm), this molded hose fits specific cooling system layouts without the need for bending or adjustment. The absence of an internal spring ensures unobstructed coolant flow, reducing the risk of blockages or pressure drops.

Applications and Common Issues Addressed

• Replacement of worn or cracked radiator coolant hoses in Mitsubishi Galant and Nissan Maxima
• Resolving coolant leaks caused by hose degradation in Toyota Corolla and Volvo 240
