It is the refundable charge raised against the old injector when the exchange unit is bought, and it comes back once the worn injector is returned. The line itself is an accounting entry rather than a part, so nothing ships against it on its own. Under Volvo Penta's core numbering the exchange unit it belongs to takes part number 3801978, which is the number to quote for the component itself. The other injector core in this block is 3804933, and nothing published against the two separates them, so order the number that matches the injector actually coming off.\n\u003c\/p\u003e\n\u003ch2\u003e\n ⚙️ Key Features\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Core deposit line, not an injector you can fit\n \u003c\/li\u003e\n \u003cli\u003e\n  Belongs with the exchange unit, part number 3801978\n \u003c\/li\u003e\n \u003cli\u003e\n  Refunded when the old injector is returned\n \u003c\/li\u003e\n \u003cli\u003e\n  Not separable from injector core 3804933, so order by part number\n \u003c\/li\u003e\n \u003cli\u003e\n  Fuel System group\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 🔌 Function\n\u003c\/h2\u003e\n\u003cp\u003e\n As a line item it carries the refundable core charge on the exchange; the injector itself meters the fuel for its cylinder and atomises it into the combustion chamber at the moment of injection.\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 injector being exchanged\n \u003c\/li\u003e\n \u003cli\u003e\n  Rough idle with a knock from one cylinder, worst when the engine is cold\n \u003c\/li\u003e\n \u003cli\u003e\n  Hard starting, smoke at the exhaust and a smell of unburnt diesel around the engine\n \u003c\/li\u003e\n \u003cli\u003e\n  Fuel consumption up, and the oil level rising as fuel dilutes the sump\n \u003c\/li\u003e\n \u003cli\u003e\n  Uneven running that follows the cylinder when injectors are swapped between positions\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 charge is refunded when the worn injector is returned, so keep the old unit and send it back rather than scrapping it\n \u003c\/li\u003e\n \u003cli\u003e\n  Ordering this number on its own supplies no part - it goes on the order beside the exchange unit, part number 3801978\n \u003c\/li\u003e\n \u003cli\u003e\n  Renew the seat washer and the O-rings on refitting, and prove the fuel is clean and dry before the exchange unit goes in, since dirt or water will take the next one out as well\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":53385493938468,"sku":"Y299041","price":495.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0994\/8115\/7924\/files\/original_ed9e4b8d-4f55-4c12-9289-7a3c2a19b352.jpg?v=1788076655","url":"https:\/\/www.sawleysautoandmarine.com.au\/products\/3804978-injector-core-genuine-volvo-penta","provider":"Sawley's Auto and Marine","version":"1.0","type":"link"}
