This OE-style molded hose uses EPDM construction and a 16 mm (0.62 in) inside diameter at both ends for direct-fit routing in select Mitsubishi, Pontiac, Nissan, Mercury, and Buick applications.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEPDM construction for coolant, water, and air service\u003c\/li\u003e\n\u003cli\u003eFactory-molded shape for smaller, tighter-fitting engine compartments\u003c\/li\u003e\n\u003cli\u003e16 mm (0.62 in) inside diameter at both ends\u003c\/li\u003e\n\u003cli\u003eCenterline length: 15.4 in (391 mm)\u003c\/li\u003e\n\u003cli\u003eApproved for marine applications\u003c\/li\u003e\n\u003cli\u003eOE-style molded heater hose design\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eProduct Details\u003c\/h2\u003e\u003cp\u003eThe Gates Molded Heater Hose line is built around factory-shaped routing for vehicles that need a formed hose rather than a universal straight section. Part number 18704 follows the molded profile needed to connect heater and coolant passages cleanly, helping maintain proper hose routing in confined spaces. This hose is listed for applications such as the 1999 Mitsubishi Eclipse heater inlet and heater outlet, as well as select Mitsubishi Galant, Pontiac Sunbird, Nissan Sentra, Nissan Pulsar NX, Mercury Tracer, and Buick Skyhawk heater hose positions.\u003c\/p\u003e\u003cp\u003eThis part cross-references Dayco 87620 for the same application.\u003c\/p\u003e\u003ch2\u003eCommon Uses\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacing a cracked or leaking heater hose in the cooling system\u003c\/li\u003e\n\u003cli\u003eRestoring proper coolant flow to the heater core circuit\u003c\/li\u003e\n\u003cli\u003eReplacing a hose with collapsed bends or poor routing\u003c\/li\u003e\n\u003cli\u003eAddressing coolant seepage at molded hose sections\u003c\/li\u003e\n\u003cli\u003eServicing heater inlet, heater outlet, and heater-to-pipe connections\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eVerify the vehicle’s heater hose position before ordering, since fitment varies by year, make, model, and location.\u003c\/li\u003e\n\u003cli\u003eMatch the molded shape and centerline length to the original hose routing.\u003c\/li\u003e\n\u003cli\u003eInspect clamps, pipe ends, and adjacent coolant lines before installation.\u003c\/li\u003e\n\u003cli\u003eConfirm the 16 mm inside diameter matches both connection points.\u003c\/li\u003e\n\u003cli\u003eUse the vehicle’s cooling system service procedure after installation to restore proper coolant level and circulation.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eGates manufactures this molded heater hose as an OE-style replacement for applications that require factory-form routing and EPDM hose construction.
