The hose is formed in a curved profile and uses EPDM material, which is commonly specified for coolant transfer service because it handles heat and fluid exposure in engine bay use. The dual I.D. construction supports the different end sizes required by the application, and the hose is identified by the Dayco 72436 part number for ordering and catalog lookup.\u003c\/p\u003e\u003cp\u003eThis part cross-references ACDelco 22707M and Gates 23812 for the same application. For BMW 540i, BMW 740i, and BMW 740iL cooling system repairs, Dayco 72436 provides a direct replacement format for the lower radiator hose position listed in the fitment data.\u003c\/p\u003e\u003ch2\u003eWhat It Is Used For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacing a cracked or leaking coolant hose\u003c\/li\u003e\n\u003cli\u003eRestoring coolant flow in the lower radiator circuit\u003c\/li\u003e\n\u003cli\u003eAddressing hose swelling, soft spots, or age-related deterioration\u003c\/li\u003e\n\u003cli\u003eCorrecting fitment issues caused by an incorrect hose profile\u003c\/li\u003e\n\u003cli\u003eServicing BMW cooling system leaks identified at the hose connection points\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eVerify the hose routing, end diameters, and lower position before installation.
