Gates 20602 Radiator Coolant Hose - Lower or Upper

Gates 20602 Molded Coolant Hose Overview

The Gates 20602 molded coolant hose is built for radiator and heater circuit service where a formed hose is required for proper routing and fit. Made from EPDM and molded to OEM-style dimensions, it supports upper and lower coolant applications across a wide range of Chrysler, Dodge, Jeep, Chevrolet, Oldsmobile, and Pontiac vehicles.

Gates Molded Coolant Hose line is engineered as a broad replacement range for radiator hose service, heater hose routing, bypass connections, and other coolant paths. The formed shape helps match factory hose routing on vehicles such as the Dodge Dart, Chrysler Town & Country, and Jeep CJ5, reducing the need to adapt straight hose in place of a molded design.
