It uses EPDM material, a molded hose shape, and clamp-style end attachments to match the original routing and connection points. The aluminum T-connector is the key design update, replacing the plastic connector that commonly cracks and leads to heater hose failure. This makes it a practical choice for Buick Lucerne and Cadillac DTS models that need a replacement heater hose assembly with improved connector durability. The part number 626-712 also cross-references Gates 19846 and BBB Industries 23356 for the same application.\u003c\/p\u003e\u003ch2\u003eVehicle Fitment\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFits 2006-2011 Buick Lucerne, Inlet and Outlet\u003c\/li\u003e\n\u003cli\u003eFits 2006-2011 Cadillac DTS, Inlet and Outlet\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon Problems This Part Can Help Solve\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCracked plastic T-connector in the heater hose assembly\u003c\/li\u003e\n\u003cli\u003eCoolant leaks at branched hose connection points\u003c\/li\u003e\n\u003cli\u003eLoss of heater performance from restricted coolant flow\u003c\/li\u003e\n\u003cli\u003eDamaged or deteriorated molded heater hose routing\u003c\/li\u003e\n\u003cli\u003eFailure at clamp-connected inlet and outlet hose ends\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify the inlet and outlet routing before installation and compare the original hose shape, branch layout, and connector locations to the replacement assembly. Inspect mating surfaces, clamps, and nearby heat sources during service, and confirm the hose follows the factory path without kinks or twist. Dorman 626-712 is a molded assembly, so correct positioning is important for proper fit on Buick Lucerne and Cadillac DTS heater hose applications.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDorman OE FIX parts are engineered to correct a known weak point in the original design by upgrading the connector material.
