Gates 21394 Radiator Coolant Hose - Lower or Upper

Gates 21394 Molded Coolant Hose Overview

Gates 21394 is a molded radiator coolant hose built to OEM-quality specifications for upper, lower, bypass, heater, and other coolant routing needs. The EPDM construction and molded shape support a precise replacement for vehicles that require a formed hose rather than a universal cut-to-fit part.

The Gates Molded Coolant Hose line is engineered as a broad replacement solution for radiator hose service, helping reduce the need to source an OE dealer hose for common cooling-system repairs.
