Overview

When the plastic heater hose or coolant hose connector in your engine bay starts to crack from heat and abrasion, a leak can follow. The Dorman 800-414HP Metal Heater Hose Connector is built to be a rugged, long-lasting alternative that aligns with the factory design for select Cadillac, Chevrolet, and GMC models.
