Made from a high quality zinc composition, it provides corrosion protection by sacrificially wearing away in place of surrounding metal components, helping to extend the service life of the cooling system it is installed in. The anode features a machined exterior for a precise, consistent fit and is manufactured to meet or exceed the quality of the original equipment part it replaces.\u003c\/p\u003e\u003cp\u003eThis anode is a direct cross-reference match for GLM 12789 and Volvo Penta 838929, making it a straightforward replacement for boat owners maintaining Volvo Penta fresh water cooling systems. At just 0.09 pounds, it is a lightweight, low-cost maintenance item that should be inspected and replaced periodically as part of routine sacrificial anode upkeep to protect against galvanic corrosion.\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 18-6001\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Zinc Anode\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Zinc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExterior Finish:\u003c\/strong\u003e Machined\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.09 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Dimensions:\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999320124\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Volvo Penta Anodes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eDesigned for use with Volvo Penta fresh water cooler systems.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eGLM 12789\u003c\/li\u003e\n\u003cli\u003eVolvo Penta 838929\u003c\/li\u003e\n\u003cli\u003eVOLVO 838929-8\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-6001 anode fit?\u003c\/strong\u003e The Sierra 18-6001 is designed for use with Volvo Penta fresh water cooler systems.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-6001 the same as GLM 12789?\u003c\/strong\u003e Yes, the Sierra 18-6001 zinc anode cross-references directly to GLM 12789, so either number identifies the same replacement part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-6001 anode replace Volvo Penta 838929?\u003c\/strong\u003e Yes, the Sierra 18-6001 is interchangeable with Volvo Penta part numbers 838929 and 838929-8.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the Sierra 18-6001 anode made from?\u003c\/strong\u003e It is made from a zinc composition, which is standard for sacrificial anodes used in marine cooling systems.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-6001 anode weigh?\u003c\/strong\u003e The Sierra 18-6001 zinc anode weighs 0.09 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the Sierra 18-6001 anode?\u003c\/strong\u003e The Sierra 18-6001 measures 0.39 x 0.39 x 0.39 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a genuine Sierra part or an aftermarket copy?\u003c\/strong\u003e The 18-6001 is a genuine Sierra product manufactured to meet or exceed the quality of the original equipment anode it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy does a fresh water cooler need a zinc anode?\u003c\/strong\u003e A zinc anode like the Sierra 18-6001 sacrifices itself to galvanic corrosion, protecting the surrounding metal components of the fresh water cooler from corroding instead.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow often should the 18-6001 anode be replaced?\u003c\/strong\u003e Sacrificial zinc anodes such as the Sierra 18-6001 should be inspected periodically and replaced once significantly worn to maintain continued corrosion protection.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat finish does the Sierra 18-6001 have?\u003c\/strong\u003e The Sierra 18-6001 anode has a machined exterior finish for a precise, consistent fit.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988347760859,"sku":"SIE-18-6001","price":11.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-6001_lg__37477.1558128018.500.750.jpg?v=1785189040","url":"https:\/\/www.goodvibesmarina.com\/products\/zinc-anode-for-volvo-penta-fresh-water-cooler-replaces-838929-fits-aq200-md19-md32-aq30-aq41-2003-mpn-18-6001","provider":"Good Vibes Marina","version":"1.0","type":"link"}
