Because the visible public references are narrow and centered on that specific schematic rather than a broad model table, the safest compatibility statement is to match this pressure cap to the exact Volvo Penta cooling-system diagram and serial-number-based application before ordering.\u003c\/p\u003e\n\u003ch2\u003eSerial Number Fitment Notice\u003c\/h2\u003e\n\u003cp\u003eMatch Volvo Penta part number \u003cstrong\u003e23321023\u003c\/strong\u003e to your engine serial number and the correct Volvo Penta cooling-system diagram before ordering. Cooling-system caps and expansion-tank hardware can vary by engine family, tank design, and production break, even when the surrounding heat exchanger layout looks very similar.\u003c\/p\u003e\n\u003ch2\u003eWhen This Part Needs Replacement\u003c\/h2\u003e\n\u003cp\u003eThis pressure cap should be replaced when the seal is worn, the spring tension is weak, the cap no longer holds pressure correctly, or there are visible signs of corrosion, damage, or coolant loss around the expansion tank neck. It is also smart to inspect it anytime the expansion tank or nearby cooling-system components are already being serviced. This service guidance is an inference based on the part being identified as the cooling-system pressure cap on the expansion tank assembly.\u003c\/p\u003e\n\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\n\u003cp\u003eConfirm the exact application in the correct Volvo Penta schematic before installation, and compare the removed cap carefully against the replacement part. Inspect the expansion-tank neck and sealing surface before fitting the new cap, since pressure-cap performance depends on both correct application and a clean, undamaged sealing seat. This installation guidance is grounded in the part's placement on the expansion tank within the D6 cooling-system schematic.\u003c\/p\u003e\n\u003ch2\u003eAlternate\/Superseded Part Numbers\u003c\/h2\u003e\n\u003cp\u003eThe reviewed sources continue to list \u003cstrong\u003e23321023\u003c\/strong\u003e as an active Volvo Penta OEM number. I did not find a clearly supported Volvo Penta superseded replacement number in the current source set.\u003c\/p\u003e\n\u003ch2\u003eParts Desk Insight\u003c\/h2\u003e\n\u003cp\u003eWith cooling-system caps like this, the easy mistake is assuming a cap that looks similar will work the same way. Matching the exact expansion-tank diagram first usually saves time, especially when cap style alone does not confirm the correct pressure rating or tank application.\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":43563994382372,"sku":"23321023","price":45.9,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/5f185c1f-87df-4d13-808c-56424cb06f5f.png?v=1776478385","url":"https:\/\/marisolmarine.com\/products\/volvo-364","provider":"Marisol Marine Company","version":"1.0","type":"link"}
