It seals each exhaust port against high-temperature combustion gas leakage. Because these gaskets are used individually at each port, the correct quantity depends on the engine configuration — D5 four-cylinder engines typically require \u003cstrong\u003e4 gaskets\u003c\/strong\u003e, while D7 six-cylinder engines typically require \u003cstrong\u003e6 gaskets\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eCompatible Applications\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eD5 Series\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eVolvo Penta D5A-A T\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D5A-A TA\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D5A-B TA\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D5A-T\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D5A-TA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eD7 Series\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eVolvo Penta D7A-A T\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D7A-A TA\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D7A-B TA\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D7A-T\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D7A-TA\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D7C-TA\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D7C-B TA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eFitment is assembly-specific and can vary by engine serial number and manifold configuration (Low Mounted Turbo assembly A or B).

Once an exhaust manifold gasket has been compressed and exposed to heat cycling, reusing it increases the risk of leakage after reassembly. Replace with a new gasket whenever the manifold is removed.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How many gaskets do I need?\u003c\/strong\u003e\u003cbr\u003eA: D5 four-cylinder engines typically use 4; D7 six-cylinder engines typically use 6. Confirm the exact quantity against the Volvo Penta parts diagram for your engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is 20405589 still available or has it been replaced?\u003c\/strong\u003e\u003cbr\u003eA: 20557208 is the current active Volvo Penta number. Earlier numbers 20405589, 20460296, and 20505955 have been superseded by 20557208.\u003c\/p\u003e\n\n\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\n\u003cp\u003eThis is one of those parts where the quantity matters as much as the part number — ordering one gasket when you need a full set of four or six is a common mistake that leads to a return trip. If the manifold is already off, replace the complete set while you have access. The gasket is one of the least expensive items in an exhaust manifold service, and skipping fresh gaskets to save a few dollars often leads to repeat labor when the assembly starts leaking again after reassembly.\u003c\/p\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43563977605156,"sku":"20557208","price":7.9,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/09d7b1e2-9b1a-4f65-9416-d8f1d851eb60.png?v=1775860005","url":"https:\/\/marisolmarine.com\/products\/volvo-penta-exhaust-manifold-gasket-20557208","provider":"Marisol Marine Company","version":"1.0","type":"link"}
