It is the pump that drives raw water or coolant through the engine's cooling passages, keeping operating temperatures in the safe range during run time. The pump is designed as a direct replacement for the OEM RA057018 unit, so it bolts into the same location and mates with the same drive arrangement without modification.\u003c\/p\u003e\u003cp\u003eA mounting gasket, Sierra part 18-0981, is included with the pump so the installation is complete without having to source a separate gasket. This keeps the replacement job straightforward: remove the worn or leaking factory pump, transfer any brackets or fittings as needed, install the new pump with the included gasket, and reconnect the cooling hoses. The pump is intended for GM V-6 and small block V-8 marine engine applications, matching the fitment of the original RA057018 pump it replaces.\u003c\/p\u003e\u003cp\u003eThis water pump is categorized among circulating water pumps and impellers for inboard cooling systems, reflecting its role as a serviceable cooling-system component rather than a sealed, non-repairable assembly. Owners replacing a worn, seized, or leaking water pump on a GM-based marine V-6 or small block V-8 can use this part number to source a like-for-like replacement.\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 18-3586-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e PleasureCraft Water Pumps \u0026amp; Impellers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine Application:\u003c\/strong\u003e GM V-6 \u0026amp; small block V-8 engines\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGasket Included:\u003c\/strong\u003e 18-0981\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e RA057018\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 3.91 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282369644\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eGM V-6 \u0026amp; small block V-8 marine engines\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eRA057018\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-3586-1 water pump replace?\u003c\/strong\u003e The Sierra 18-3586-1 is a direct replacement for OEM part RA057018, so it fits in place of the original pump without modification.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs a gasket included with this water pump?\u003c\/strong\u003e Yes, the 18-3586-1 water pump ships with Sierra gasket 18-0981 included, so no separate gasket purchase is needed for installation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the 18-3586-1 water pump fit?\u003c\/strong\u003e This pump is designed for GM V-6 and small block V-8 marine engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-3586-1 water pump weigh?\u003c\/strong\u003e The Sierra 18-3586-1 circulating water pump weighs 3.91 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-3586-1 a genuine Sierra part?\u003c\/strong\u003e Yes, 18-3586-1 is the Sierra manufacturer part number for this circulating water pump, not an aftermarket clone.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this pump work as a like-for-like swap for a worn OEM RA057018 pump?\u003c\/strong\u003e Because 18-3586-1 replaces RA057018 directly, it is intended as a like-for-like swap on GM V-6 and small block V-8 marine engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat type of pump is the 18-3586-1?\u003c\/strong\u003e It is a circulating water pump used in the raw water or coolant cooling system of GM V-6 and small block V-8 marine engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-3586-1 come with mounting hardware besides the gasket?\u003c\/strong\u003e The included component confirmed for this pump is gasket 18-0981; no other hardware is specified for the 18-3586-1.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included in the box with the 18-3586-1 water pump?\u003c\/strong\u003e The box includes the Sierra 18-3586-1 circulating water pump along with gasket 18-0981.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the 18-3586-1 be used on any GM marine V-8?\u003c\/strong\u003e The 18-3586-1 is specified for GM V-6 and small block V-8 marine engines; confirm your engine matches this small block V-8 or V-6 configuration before ordering.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988154200283,"sku":"SIE-18-3586-1","price":343.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-3586_lg__06979.1654709010.500.750.jpg?v=1785329153","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-3586-1-marine-circulating-water-pump-replaces-johnson-pump-10-24228-1","provider":"Good Vibes Marina","version":"1.0","type":"link"}
