Made from EPDM and finished in black, it is specified for vehicles such as the Chevrolet Impala, Pontiac Grand Prix, Buick Allure, Buick LaCrosse, and Chevrolet Monte Carlo.\u003c\/p\u003e\u003cp\u003eDayco’s Curved Radiator Hose line focuses on application-specific hose geometry and OE-style cooling system fitment. This Dayco 72365 hose follows the required curved layout for lower radiator connections where a straight hose will not maintain the correct path or clearance.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEPDM construction for coolant system service\u003c\/li\u003e\n\u003cli\u003eBlack finish for a clean OE-style appearance\u003c\/li\u003e\n\u003cli\u003eDual I.D. hose design with 1 1\/4 in. end 1 inside diameter and 1 1\/2 in. end 2 inside diameter\u003c\/li\u003e\n\u003cli\u003eEnd outside diameters measure 1 9\/16 in. and 1 13\/16 in.\u003c\/li\u003e\n\u003cli\u003eBuilt to SAE J20R4 Class D-1 and SAE J1684 Type EC specifications\u003c\/li\u003e\n\u003cli\u003eLower curved radiator hose configuration for proper routing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eProduct Details\u003c\/h2\u003e\u003cp\u003eThis radiator coolant hose is engineered for lower cooling system routing on 2005-2008 Pontiac Grand Prix, 2006-2009 Chevrolet Impala, 2006-2007 Chevrolet Monte Carlo, and 2008-2009 Buick Allure and Buick LaCrosse. The molded curved shape helps maintain the intended hose path between the radiator and engine-side connection points, while the EPDM material is commonly used in coolant applications for heat and fluid exposure resistance. Dayco 72365 is a direct-fit style replacement for the listed vehicles and applications.\u003c\/p\u003e\u003cp\u003eThis part cross-references ACDelco 26538X and Gates 23120 for the same application.

Compare the inside and outside diameters to the original hose and confirm that the curved shape matches the factory path. Inspect hose clamps, radiator necks, and engine fittings for wear or corrosion before installing the new hose. Fill and bleed the cooling system according to the vehicle service procedure after replacement.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDayco manufactures this hose to meet SAE J20R4 Class D-1 and SAE J1684 Type EC requirements, supporting consistent material and dimensional standards for cooling system service.\u003c\/p\u003e","brand":"Dayco","offers":[{"title":"Default Title","offer_id":52954927333557,"sku":"BCWL-72365","price":78.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/DY_72365_Fro.jpg?v=1786341922","url":"https:\/\/www.partcatalog.com\/products\/dayco-72365-radiator-coolant-hose-lower","provider":"PartCatalog","version":"1.0","type":"link"}
