It threads into the engine cooling passage to monitor coolant temperature and send that reading to the gauge or engine control system, giving the operator an accurate, real-time view of engine operating temperature. Reliable temperature sensing is critical on a marine engine, where overheating can cause serious damage before a problem is visually apparent, so a correctly functioning sensor is one of the simpler but more important components in the cooling and instrumentation system.\u003c\/p\u003e\u003cp\u003eThis sensor is designed as a direct cross-reference for the OEM part it replaces, so installation follows the same fit, thread, and electrical connection as the original Mercruiser sensor it is replacing. It is cataloged under Mercruiser temperature and oil sender applications, making it a straightforward swap for boat owners and marine technicians performing routine sender replacement or troubleshooting an inaccurate temperature gauge. At 0.12 pounds, it is a compact, lightweight component that is easy to keep on hand as a spare.\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 18-7600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Coolant Temperature Sensor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Mercruiser Temp \u0026amp; Oil Senders\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999977076\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.12 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eDesigned for Mercruiser temperature and oil sender applications.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e47002\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-7600 replace?\u003c\/strong\u003e The Sierra 18-7600 coolant temperature sensor is a direct replacement for Mercruiser part number 47002.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-7600 used for?\u003c\/strong\u003e It is a coolant temperature sensor that monitors engine coolant temperature and sends that reading to the gauge or engine control system on Mercruiser applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-7600 sensor weigh?\u003c\/strong\u003e The Sierra 18-7600 weighs 0.12 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-7600 an OEM or aftermarket part?\u003c\/strong\u003e The 18-7600 is a Sierra-branded replacement sensor cataloged as a cross-reference to Mercruiser OEM part 47002, so it serves as an aftermarket equivalent to the original sender.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat category of sender is the 18-7600?\u003c\/strong\u003e Sierra part 18-7600 is cataloged under Mercruiser temperature and oil senders.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 18-7600 fit any boat engine?\u003c\/strong\u003e The Sierra 18-7600 is cataloged specifically as a Mercruiser temperature sender replacing part number 47002; confirm your existing sensor's part number before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-7600?\u003c\/strong\u003e The UPC for the Sierra 18-7600 coolant temperature sensor is 030999977076.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy would I need to replace a coolant temperature sensor like the 18-7600?\u003c\/strong\u003e A failing coolant temperature sensor can cause an inaccurate or unresponsive temperature gauge reading, and replacing it with the Sierra 18-7600 restores accurate engine temperature monitoring.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-7600 include mounting hardware?\u003c\/strong\u003e The Sierra 18-7600 is supplied as the sensor itself; no additional components are listed with it.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I know if my sensor matches the 18-7600?\u003c\/strong\u003e Check your existing sender for the Mercruiser part number 47002, which is the number the Sierra 18-7600 is cataloged to replace.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988385247451,"sku":"SIE-18-7600","price":45.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-7600_lg__47159.1558129827.500.750.jpg?v=1785329155","url":"https:\/\/www.goodvibesmarina.com\/products\/marine-coolant-temperature-sensor-for-mercruiser-replaces-oem-47002-sierra-18-7600","provider":"Good Vibes Marina","version":"1.0","type":"link"}
