Customers who select by horsepower alone can end up with the wrong kit variant. Always verify the OEM number — 06192-ZV7-000, 06192-ZV7-010, or 06192-ZW2-000 — against your engine's parts diagram before ordering. If your engine references 06192-ZV7-020, confirm compatibility with Sierra's catalog before purchasing.\u003c\/p\u003e\n\u003cp\u003eBrowse all water pump service kits in our \u003ca href=\"\/collections\/impeller-service-kits\"\u003eImpeller Service Kits\u003c\/a\u003e collection, or shop \u003ca href=\"\/collections\/engine-parts-maintenance\"\u003eEngine Parts \u0026amp; Maintenance\u003c\/a\u003e for related cooling system components.\u003c\/p\u003e","brand":"LNS","offers":[{"title":"Default Title","offer_id":51156138295332,"sku":"47-3281","price":59.89,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/47-3281.jpg?v=1784926787","url":"https:\/\/marisolmarine.com\/products\/sierra-honda-water-pump-service-kit-18-3281-bf25-bf30","provider":"Marisol Marine Company","version":"1.0","type":"link"}
