As a general rule, any gasket that has been disturbed during service should be replaced — reusing a compressed or deformed gasket is one of the most common causes of repeat leaks after a repair.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCommon Issues:\u003c\/strong\u003e Gaskets are one of the easiest parts to mis-order because many Volvo Penta gaskets look similar in photos. The safest approach is to confirm part number 21584008 directly against your engine serial number and the relevant diagram position. If you have the old gasket in hand, the part number is often stamped or printed on it. Contact us with your engine model and serial number if you need help confirming the correct part before ordering.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eAlways replace gaskets rather than reusing them. Clean mating surfaces thoroughly before installation and inspect for warping or damage. Use the torque specifications from your Volvo Penta service manual for all fasteners. Do not reuse the old gasket.\u003c\/p\u003e\n\n\u003ch3\u003eService Interval\u003c\/h3\u003e\n\u003cp\u003eGaskets are not a scheduled replacement item. Replace whenever the mating component is disassembled for service, or when a leak is traced to the gasket location. Inspect adjacent seals and O-rings at the same time and replace as needed.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical FAQ\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How do I confirm this is the right gasket for my engine?\u003c\/strong\u003e\u003cbr\u003eA: Cross-reference part number 21584008 against your engine model and serial number in the Volvo Penta parts diagram. If you have the old gasket, check for a part number stamped on it. Contact us with your serial number if you need help confirming.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I reuse the old gasket if it looks okay?\u003c\/strong\u003e\u003cbr\u003eA: No — Volvo Penta recommends replacing gaskets any time they are disturbed. A gasket that has been compressed and released will not seal reliably and is a common source of repeat leaks.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Should I replace other seals and O-rings at the same time?\u003c\/strong\u003e\u003cbr\u003eA: Yes — whenever a component is disassembled, it's best practice to replace all gaskets, seals, and O-rings in the assembly. This avoids having to re-open the engine shortly after for a seal that was borderline at the time of service.\u003c\/p\u003e\n\n\u003ch3\u003eRelated Parts\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/volvo-penta-gasket-3852111\"\u003eVolvo Penta Gasket 3852111\u003c\/a\u003e — related OEM engine gasket\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/volvo-penta-sealing-ring-3582673\"\u003eVolvo Penta Sealing Ring 3582673\u003c\/a\u003e — related sealing component\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/volvo-penta-gasket-kit-3812357\"\u003eVolvo Penta Gasket Kit 3812357\u003c\/a\u003e — comprehensive gasket kit for engine service\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/volvo-penta-gasket-kit-876267\"\u003eVolvo Penta Gasket Kit 876267\u003c\/a\u003e — related gasket kit\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43563988582436,"sku":"21584008","price":24.7,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/7068232f-c920-4ddf-9a38-68f1caf49499.png?v=1772667416","url":"https:\/\/marisolmarine.com\/products\/volvo-penta-gasket-21584008","provider":"Marisol Marine Company","version":"1.0","type":"link"}
