It closes and seals the end of the charge air cooler, maintaining the integrity of the pressurized intake-air system. A failed or leaking cap allows pressurized charge air to escape before it reaches the engine, reducing power output and potentially triggering boost-related fault codes.\u003c\/p\u003e\n\n\u003ch2\u003eCompatible Applications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eVolvo Penta D4-145, D4-150, D4-175, D4-180\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D4-210, D4-225, D4-230, D4-260, D4-270, D4-300, D4-320\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D6-280, D6-300, D6-310, D6-330, D6-350\u003c\/li\u003e\n\u003cli\u003eVolvo Penta D6-370, D6-400, D6-435, D6-440, D6-480\u003c\/li\u003e\n\u003cli\u003eApplies across A-, D-, and I-series configurations depending on engine generation and suffix\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eD4 and D6 engines were produced with different charge air cooler configurations across model years and variants.

Also replace if inspection identifies an air or pressure leak around the charge air cooler end assembly. Inspect the associated seals and cooler housing at the same time.\u003c\/p\u003e\n\n\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\n\u003cp\u003eClean and inspect the charge air cooler mating surface before installation. Check the related sealing components and fasteners for wear or corrosion. Follow the applicable Volvo Penta workshop procedure for assembly sequence and tightening torque. Pressure-test the charge air system after installation to confirm the repair is sealed before returning the vessel to service.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical FAQ\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is a charge air cooler cap and why does it matter?\u003c\/strong\u003e\u003cbr\u003eA: The charge air cooler (aftercooler) cools compressed air from the turbocharger before it enters the engine. The end cap seals the cooler assembly under boost pressure. A cracked or leaking cap reduces charge air density, lowering power output and fuel efficiency, and can trigger boost-related fault codes on D4 and D6 engines.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does 22092538 replace 3583628?\u003c\/strong\u003e\u003cbr\u003eA: Yes. 22092538 is the current Volvo Penta OEM part number that supersedes 3583628.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does this fit all D4 and D6 engines?\u003c\/strong\u003e\u003cbr\u003eA: It is documented across a wide range of D4 and D6 models, but charge air cooler configurations vary by engine generation and suffix. Always confirm by complete engine model, suffix, and serial number before ordering.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What other parts should I inspect when replacing this cap?\u003c\/strong\u003e\u003cbr\u003eA: Inspect the charge air cooler end seals, housing, and all related fasteners. If the cap failed due to pressure stress, also inspect the charge air hoses and clamps for signs of fatigue or leakage.\u003c\/p\u003e\n\n\u003ch2\u003eParts Desk Insights\u003c\/h2\u003e\n\u003cp\u003eThe key distinction with 22092538 is that it is the charge air cooler end cap — not a generic engine cover, filler cap, or coolant cap. Customers sometimes order the wrong cap because \"cap\" appears across many Volvo Penta part categories. On D4 and D6 engines, matching the exact aftercooler assembly and engine suffix is the safest way to confirm fitment. If a customer is replacing this cap due to a boost leak or power loss complaint, also recommend inspecting the charge air hoses and intercooler seals before closing the job.\u003c\/p\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43563991072804,"sku":"22092538","price":562.0,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/85db649f-e31e-4bc2-8c48-dcf4d0079ff0.png?v=1787450651","url":"https:\/\/marisolmarine.com\/products\/volvo-272","provider":"Marisol Marine Company","version":"1.0","type":"link"}
