Product Details

Dorman 66249 is used at the turbocharger coolant line banjo bolt to help keep coolant contained at the joint and contaminants out of the line. Because the seal is created by the washer, it should be replaced whenever the bolt is loosened and removed during service. This part cross-references Ford AA5Z00810B for the same application. It is a practical replacement for turbo coolant line service on Ford Explorer, Ford Flex, Ford Taurus, and Lincoln MKT models where the banjo-style coolant connection is used.
