If your engine has multiple drain points, confirm how many are required for your specific application.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this the same as 20553989?\u003c\/strong\u003e\u003cbr\u003eYes — 20553989 is the superseded number. 20579690 is the current active Volvo Penta part number for this application.\u003c\/p\u003e\n\n\u003ch2\u003eParts Desk Insights\u003c\/h2\u003e\n\u003cp\u003eThis is one of those parts that customers often forget to order until they're mid-service with the plug already out. It's a good idea to keep a few on hand if you do your own oil changes — they're inexpensive and the cost of a small oil seep (cleanup, repeat service, potential damage) far outweighs the cost of a fresh gasket. If you're unsure whether this is the right sealing ring for your drain plug, have your engine serial number ready and we can help confirm.\u003c\/p\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43563977637924,"sku":"20579690","price":8.5,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/fce9d89b-539c-4653-9c12-0a5c1a17f7b1.png?v=1776140135","url":"https:\/\/marisolmarine.com\/products\/volvo-penta-oil-drain-plug-gasket-20579690","provider":"Marisol Marine Company","version":"1.0","type":"link"}
