The strongest current fitment trail places this seal in \u003cstrong\u003eD4 and D6 heat exchanger and oil-cooler thermostat related assemblies\u003c\/strong\u003e, where it is used as part of the cooling-system sealing stack for the exact applications that call for this number.

Current references associate it with many D4 and D6 variants, including engines in the \u003cstrong\u003eD4-180 through D4-300\u003c\/strong\u003e range and \u003cstrong\u003eD6-280 through D6-480\u003c\/strong\u003e range, depending on the exact serial-number-based application. The clearest assembly-level evidence places it in \u003cstrong\u003eheat exchanger components\u003c\/strong\u003e and \u003cstrong\u003eoil cooler for engine with keel cooling\u003c\/strong\u003e references. The safest fitment standard is the exact Volvo Penta serial-number-based parts diagram for the engine being serviced.\u003c\/p\u003e\n\u003ch2\u003eSerial Number Fitment Notice\u003c\/h2\u003e\n\u003cp\u003eFitment can vary by engine family, cooling-system layout, heat-exchanger version, and thermostat or oil-cooler configuration. Confirm Volvo Penta part number \u003cstrong\u003e3583831\u003c\/strong\u003e against your engine serial number and the correct Volvo Penta cooling-system diagram before ordering, especially where nearby O-rings in the same cooling stack can look similar but seal different positions.\u003c\/p\u003e\n\u003ch2\u003eWhen This Part Needs Replacement\u003c\/h2\u003e\n\u003cp\u003eReplace this O-ring whenever the related heat exchanger, oil-cooler thermostat housing, or adjacent cooling assembly has been opened, or when the original seal shows flattening, hardening, swelling, seepage, or damage during removal. It is also a smart replacement during cooling-system service when the thermostat-kit style sealing group is already apart. This service guidance is based on the part type and the current cooling-system application trail.\u003c\/p\u003e\n\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\n\u003cp\u003eMatch this O-ring to the exact Volvo Penta application before installation. The strongest current references place it in the \u003cstrong\u003eheat exchanger \/ oil-cooler thermostat\u003c\/strong\u003e sealing group, so confirming both the part number and exact diagram position is the safest cross-check before ordering or reassembly. Clean the sealing groove carefully and verify the neighboring O-rings in the same cooling stack, since this seal is commonly serviced with adjacent O-rings \u003cstrong\u003e3583830\u003c\/strong\u003e and \u003cstrong\u003e3583832\u003c\/strong\u003e.\u003c\/p\u003e\n\u003ch2\u003eAlternate\/Superseded Part Numbers\u003c\/h2\u003e\n\u003cp\u003eUse Volvo Penta \u003cstrong\u003e3583831\u003c\/strong\u003e as the primary ordering number for this listing. In the sources reviewed, I did not find a stronger confirmed supersession trail than the active number itself.\u003c\/p\u003e\n\u003ch2\u003eParts Desk Insight\u003c\/h2\u003e\n\u003cp\u003eCooling-system O-rings like this are easy to mix up because several neighboring seals can be replaced during the same D4 or D6 service. Matching the exact Volvo Penta diagram position first is usually much safer than comparing an old seal by size alone.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShipping:\u003c\/strong\u003e Ships same or next day for fast Canada wide shipping. ⚓\u003c\/p\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43564002476068,"sku":"3583831","price":19.2,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/1db2f2f7-d702-49e9-afd8-3eaff0059d07.png?v=1776459665","url":"https:\/\/marisolmarine.com\/products\/volvo-512","provider":"Marisol Marine Company","version":"1.0","type":"link"}
