Its EPDM material supports heat and fluid exposure commonly found in HVAC and cooling-system service. This part cross-references Dayco 87321 for the same application.\u003c\/p\u003e\u003cp\u003eFor 2006-2008 Buick Lucerne lower heater hose service, the molded profile helps maintain proper routing through the engine-to-heater path while matching the compact packaging found in modern engine compartments. The Gates 18487 is also listed under related interchange numbers including 10487 and 18487.\u003c\/p\u003e\u003ch2\u003eCommon Uses\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacing a cracked or softened lower heater hose\u003c\/li\u003e\n\u003cli\u003eRestoring coolant flow between the engine and heater core circuit\u003c\/li\u003e\n\u003cli\u003eCorrecting hose routing in a tight engine compartment\u003c\/li\u003e\n\u003cli\u003eAddressing leaks at a molded hose section\u003c\/li\u003e\n\u003cli\u003eReplacing a hose that no longer holds its factory shape\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eVerify the hose routing, end diameters, and centerline length before installation. Confirm the application as Fits 2006-2008 Buick Lucerne, Engine To Heater (Lower) and compare the original hose shape to the molded profile of the Gates 18487.
