This gasket is manufactured to meet or exceed original equipment quality, giving it a reliable, leak-free seal at the thermostat housing mating surface. It is round in shape and sold in a package of 2, so you have a spare on hand or enough to service two units in one order.\u003c\/p\u003e\u003cp\u003eInstalling a fresh thermostat housing gasket during any thermostat service, cooling system inspection, or overheating diagnosis helps ensure the housing seats correctly and holds pressure. Because it is a direct cross-reference for the Yamaha YSC-13080-00-0C and GM 3789161 gaskets, it drops into place wherever those original parts are called for, without modification.\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 18-0164-9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack Quantity:\u003c\/strong\u003e 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape:\u003c\/strong\u003e Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282161453\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e YSC-13080-00-0C, GM 3789161\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eYamaha sterndrive engines\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eYSC-13080-00-0C\u003c\/li\u003e\n\u003cli\u003eGM 3789161\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-0164-9 gasket fit?\u003c\/strong\u003e The Sierra 18-0164-9 is a thermostat housing gasket designed for Yamaha sterndrive engines, directly replacing the Yamaha YSC-13080-00-0C thermostat gasket.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-0164-9 the same as the Yamaha YSC-13080-00-0C gasket?\u003c\/strong\u003e Yes, part 18-0164-9 is a direct cross-reference for the Yamaha YSC-13080-00-0C thermostat housing gasket, so it installs in the same location without modification.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this gasket also cross-reference to a GM part number?\u003c\/strong\u003e Yes, the 18-0164-9 thermostat housing gasket also replaces GM 3789161.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many gaskets come in a package of 18-0164-9?\u003c\/strong\u003e Each package of the 18-0164-9 thermostat housing gasket contains 2 gaskets.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat shape is the 18-0164-9 thermostat housing gasket?\u003c\/strong\u003e The 18-0164-9 is a round gasket, matching the round mating surface of the thermostat housing it seals.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-0164-9 gasket weigh?\u003c\/strong\u003e The Sierra 18-0164-9 thermostat housing gasket weighs 0.01 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-0164-9 gasket genuine OEM or aftermarket?\u003c\/strong\u003e The 18-0164-9 is a Sierra-manufactured aftermarket gasket built to meet or exceed the quality of the original Yamaha YSC-13080-00-0C and GM 3789161 gaskets it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen should I replace the thermostat housing gasket?\u003c\/strong\u003e Replace the 18-0164-9 thermostat housing gasket any time the thermostat housing is removed for service, or if coolant leaks are found at the housing seam.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-0164-9 gasket?\u003c\/strong\u003e The UPC for the Sierra 18-0164-9 thermostat housing gasket is 808282161453.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I reuse the old gasket instead of buying the 18-0164-9?\u003c\/strong\u003e A new 18-0164-9 gasket is recommended rather than reusing the old one, since gaskets compress and can leak once removed from the thermostat housing.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988027093211,"sku":"SIE-18-0164-9","price":3.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-0164_lg__15556.1558117879.500.750.jpg?v=1785188014","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-0164-9-thermostat-housing-gasket-replaces-omc-311069-gm-3789161-4-6-cyl-marine-engines-pack-of-2","provider":"Good Vibes Marina","version":"1.0","type":"link"}
