Gates 21183 Radiator Coolant Hose - Upper

Gates 21183 Molded Coolant Hose

Gates 21183 is a molded radiator coolant hose built to OEM-quality specifications for upper coolant routing. Made from EPDM, it measures 1.5 in. (38 mm) inside diameter at both ends and 28.5 in. (724 mm) centerline length for a formed fit in the cooling system.

The Gates Molded Coolant Hose line covers upper, lower, bypass, heater, and other coolant applications. This molded design helps replace the original hose shape without custom bending, making it a direct choice for radiator hose replacement on select Buick, Pontiac, and Oldsmobile applications.
