The line holds the refundable charge on the worn head returned at the end of the exchange and ships nothing on its own. Under Volvo Penta's core numbering it pairs with part 3801257. At 94.437 kg it sits between the 50 kg and 110 kg head cores in this group and is a hoist job rather than a manual lift.\n\u003c\/p\u003e\n\u003ch2\u003e\n ⚙️ Key Features\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Refundable core deposit, not a fitted part\n \u003c\/li\u003e\n \u003cli\u003e\n  Pairs with part 3801257\n \u003c\/li\u003e\n \u003cli\u003e\n  94.437 kg\n \u003c\/li\u003e\n \u003cli\u003e\n  Needs a hoist to remove and crate\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 🔌 Function\n\u003c\/h2\u003e\n\u003cp\u003e\n Carries the refundable core charge on an exchange cylinder head; the head it covers closes the cylinders, carries the valves and injectors, and forms the combustion chambers.\n\u003c\/p\u003e\n\u003ch2\u003e\n ⚠️ Common Signs of Failure\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  This is a deposit line and has nothing to fail in itself; the signs below are what normally condemns the cylinder head being exchanged\n \u003c\/li\u003e\n \u003cli\u003e\n  Coolant disappearing with no external leak, or bubbles rising in the header tank\n \u003c\/li\u003e\n \u003cli\u003e\n  White smoke and a sweet smell at the exhaust once warm\n \u003c\/li\u003e\n \u003cli\u003e\n  Misfire or low compression on one or two adjacent cylinders\n \u003c\/li\u003e\n \u003cli\u003e\n  Cracks between valve seats, or seats sunk with clearances closing up\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 🛠️ Service Notes\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  The deposit is refunded when the old cylinder head is returned; ordering this line on its own supplies no part\n \u003c\/li\u003e\n \u003cli\u003e\n  Return the head complete with its valves and studs and the faces protected, since a stripped or damaged core can reduce or void the refund\n \u003c\/li\u003e\n \u003cli\u003e\n  Check the block face and renew the head bolts when the exchange head goes on, and reset valve clearances after the first heat cycle\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 📦 Condition\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Refundable core deposit - not a physical part\n \u003c\/li\u003e\n\u003c\/ul\u003e\n","brand":"Volvo Penta","offers":[{"title":"Default Title","offer_id":53381103911204,"sku":"2842759","price":1650.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0994\/8115\/7924\/files\/original_5534ad6d-7def-4fd9-9ec3-0c5980e71ff1.jpg?v=1788072845","url":"https:\/\/www.sawleysautoandmarine.com.au\/products\/3804257-cylinder-head-core-genuine-volvo-penta","provider":"Sawley's Auto and Marine","version":"1.0","type":"link"}
