The thermostat is a core cooling-system component that regulates engine operating temperature by opening and closing to control coolant flow, helping the engine reach and maintain its proper running temperature. Replacing a worn, stuck, or failed thermostat is a routine part of outboard cooling system maintenance and helps prevent overheating or over-cooling issues that can affect engine performance and longevity.\u003c\/p\u003e\u003cp\u003eThis unit carries the Sierra part number 18-3636 and is built to a compact 0.39 x 0.39 x 0.39 inch size, making it a direct fit for the cooling system housings it is designed for. Keeping the cooling system in good working order with a properly functioning thermostat supports consistent engine temperature, efficient combustion, and reduced strain on other cooling components such as the water pump and impeller.\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 18-3636\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Category:\u003c\/strong\u003e Yamaha Outboard Thermostat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282375416\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.16 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-3636 thermostat fit?\u003c\/strong\u003e The Sierra 18-3636 is categorized for Yamaha outboard engines as a cooling system thermostat.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does part number 18-3636 refer to?\u003c\/strong\u003e 18-3636 is the Sierra manufacturer part number for this outboard engine thermostat.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-3636 thermostat weigh?\u003c\/strong\u003e This thermostat weighs 0.16 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the Sierra 18-3636 thermostat?\u003c\/strong\u003e The Sierra 18-3636 measures 0.39 x 0.39 x 0.39 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does a thermostat do in an outboard engine's cooling system?\u003c\/strong\u003e A thermostat like the Sierra 18-3636 opens and closes to regulate coolant flow, helping the engine reach and hold its proper operating temperature.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-3636 a genuine Sierra part?\u003c\/strong\u003e Yes, 18-3636 is a Sierra branded thermostat, sold under Sierra's own part numbering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen should a thermostat like the 18-3636 be replaced?\u003c\/strong\u003e A thermostat is typically replaced when it fails to open or close properly, which can cause an outboard engine to run too hot or too cool; the Sierra 18-3636 is intended as a replacement part for that purpose.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when ordering the Sierra 18-3636?\u003c\/strong\u003e Ordering the Sierra 18-3636 provides one replacement thermostat unit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes replacing the thermostat require special tools?\u003c\/strong\u003e The dossier for the Sierra 18-3636 does not specify installation tool requirements; consult your engine's service manual for the housing access procedure.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat UPC is associated with the Sierra 18-3636 thermostat?\u003c\/strong\u003e The UPC for the Sierra 18-3636 thermostat is 808282375416.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988155773147,"sku":"SIE-18-3636","price":45.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/18-3636__82680.1722354961.500.750.jpg?v=1785188530","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-3636-marine-thermostat-for-yamaha-f150-f175-f200-outboards-replaces-6da-12411-01-00","provider":"Good Vibes Marina","version":"1.0","type":"link"}
