Marine thermostats regulate coolant flow so an engine reaches and holds its designed temperature range, which protects against overheating and against the fuel dilution and excess wear that come from running too cold. This kit is finished in white and is packaged as a single complete unit, ready to install in place of a worn or failing thermostat.\u003c\/p\u003e\u003cp\u003eSierra manufactures its marine parts to meet or exceed the specifications of the original equipment they replace, and this thermostat kit is supplied as a cross reference to Mallory part number 9-43156, so buyers who know either number can confirm they are ordering the correct part. It falls within Sierra's OMC Thermostats and Gaskets line, making it a straightforward like-for-like replacement for engines that use this thermostat design.\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 18-3653\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Thermostat Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e OMC Thermostats \u0026amp; Gaskets\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.16 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999236937\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross Reference (Mallory):\u003c\/strong\u003e 9-43156\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eThis thermostat kit is part of Sierra's OMC Thermostats and Gaskets category and is the direct Sierra-numbered equivalent to Mallory 9-43156.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eMallory 9-43156\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-3653 Thermostat Kit used for?\u003c\/strong\u003e It is a marine engine thermostat kit that regulates coolant flow so the engine reaches and maintains its correct operating temperature, part number 18-3653.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Mallory 9-43156 thermostat cross-reference to this part?\u003c\/strong\u003e Yes, Mallory 9-43156 is the direct cross-reference number for the Sierra 18-3653 Thermostat Kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-3653 thermostat kit weigh?\u003c\/strong\u003e The Sierra 18-3653 Thermostat Kit weighs 0.16 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the Sierra 18-3653 Thermostat Kit?\u003c\/strong\u003e This thermostat kit has a white finish.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-3653 Thermostat Kit?\u003c\/strong\u003e The UPC is 030999236937.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a genuine Sierra part or an aftermarket copy?\u003c\/strong\u003e The 18-3653 is a genuine Sierra-branded thermostat kit, manufactured to meet or exceed the specifications of the original equipment it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat category does this thermostat kit belong to?\u003c\/strong\u003e Sierra lists part 18-3653 in its OMC Thermostats \u0026amp; Gaskets category.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included with the 18-3653 kit?\u003c\/strong\u003e The Sierra 18-3653 is sold as a complete Thermostat Kit, one unit per package.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill Sierra 18-3653 perform as well as the original thermostat it replaces?\u003c\/strong\u003e Sierra states that part 18-3653 is engineered to meet or exceed the performance of the original equipment part it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I know if 18-3653 is the right thermostat for my engine?\u003c\/strong\u003e Confirm your engine's original thermostat is either Sierra 18-3653 or its cross-reference, Mallory 9-43156, before ordering.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988157051099,"sku":"SIE-18-3653","price":30.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-3653_lg__54452.1558126817.500.750.jpg?v=1785189005","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-3653-thermostat-kit-for-omc-sterndrive-cobra-replaces-omc-383307-gm-3701777-cooling-system-service-kit","provider":"Good Vibes Marina","version":"1.0","type":"link"}
