It is engineered to OEM-quality standards for correct fit, form, and function, so it installs and runs the same as the original belt it replaces. The belt is constructed with high quality polychloroprene rubber reinforced with polyester fiber tensile members, giving it oil resistance and temperature stability for consistent performance in a marine engine bay. It drives accessory components such as the power steering pump, alternator, and water pump from the crankshaft pulley, and a worn or cracked serpentine belt can lead to slipping, noise, loss of power steering assist, or reduced charging and cooling system performance. This belt fits Mercruiser MX 6.2L MPI engines built 2002-04 with serial number OM600000 and up, and Mercruiser MX 6.2L MPI Horizon engines built 2002-04 with serial number OM600000 and up. It corresponds to Mercruiser part number 57-863876 and is intended for engines fitted with power steering.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-15102\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Serpentine Belt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Polychloroprene rubber with polyester fiber tensile members\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.6 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282145361\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e United States\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Mercruiser MX 6.2L MPI and MX 6.2L MPI Horizon, 2002-04, serial OM600000 and up, engines with power steering\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMercruiser MX 6.2L MPI, 2002-04, serial number OM600000 and up\u003c\/li\u003e\n\u003cli\u003eMercruiser MX 6.2L MPI Horizon, 2002-04, serial number OM600000 and up\u003c\/li\u003e\n\u003cli\u003eFor engines with power steering\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e57-863876\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-15102 serpentine belt fit?\u003c\/strong\u003e The 18-15102 belt fits Mercruiser MX 6.2L MPI engines built 2002-04 with serial number OM600000 and up, and Mercruiser MX 6.2L MPI Horizon engines built 2002-04 with serial number OM600000 and up.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this belt work on engines without power steering?\u003c\/strong\u003e No, the Sierra 18-15102 serpentine belt is intended for MX 6.2L MPI and MPI Horizon engines that are equipped with power steering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the OEM equivalent to Sierra part 18-15102?\u003c\/strong\u003e Sierra 18-15102 corresponds to Mercruiser part number 57-863876.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 18-15102 serpentine belt made from?\u003c\/strong\u003e It is constructed from polychloroprene rubber reinforced with polyester fiber tensile members, giving it oil resistance and temperature stability.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-15102 serpentine belt weigh?\u003c\/strong\u003e The Sierra 18-15102 serpentine belt weighs 0.6 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I know if my serpentine belt needs replacement?\u003c\/strong\u003e Signs that the 18-15102 belt or a similar serpentine belt needs replacement include visible cracking, glazing, fraying edges, slipping noise, loss of power steering assist, or a squealing sound on startup.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-15102 an OEM part or aftermarket?\u003c\/strong\u003e The 18-15102 is a Sierra aftermarket serpentine belt designed to OEM-quality standards for correct fit, form, and function as a replacement for Mercruiser part 57-863876.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does this belt drive on the engine?\u003c\/strong\u003e On the Mercruiser MX 6.2L MPI and MPI Horizon engines it fits, the 18-15102 serpentine belt drives accessory components including the power steering pump from the crankshaft pulley.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat serial number range applies to my engine for this belt?\u003c\/strong\u003e The 18-15102 belt applies to MX 6.2L MPI and MPI Horizon engines built 2002-04 with serial number OM600000 and up; engines outside that serial range may require a different Sierra part number.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat country is the 18-15102 serpentine belt made in?\u003c\/strong\u003e The Sierra 18-15102 serpentine belt is made in the United States.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988087976155,"sku":"SIE-18-15102","price":93.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/18-15102__71587.1737868683.500.750.jpg?v=1785188584","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-15102-serpentine-belt-for-mercruiser-replaces-57-865615q06-13-16-in-x-105-in","provider":"Good Vibes Marina","version":"1.0","type":"link"}
