Detailed Product Description

This radiator coolant hose is built to Gates specifications for vehicles that require a molded hose shape rather than a straight universal hose. The EPDM material is commonly used in cooling-system service because it is suited to coolant exposure and under-hood temperatures. With a 1.19-inch inside diameter on both ends and a 14.8-inch centerline length, Gates 21392 is sized for the listed applications without requiring custom trimming or reshaping.

Installation Notes and Tips

Verify the vehicle’s year, make, model, and hose position before ordering. Compare the original hose shape, end diameters, and centerline length to the replacement part to confirm the routing matches the cooling-system layout. Drain coolant as needed before removal, inspect adjoining necks and clamps for wear, and replace any damaged sealing surfaces before installing the new hose.
