It supersedes part number 840741. The serial breakpoint is the whole point of this row — engines before that number take a different exchanger. Brackets 859095 and 859363 in this run cover the same 10 D-series applications. It is a shell-and-tube exchanger, closed coolant on one side and raw water on the other.\n\u003c\/p\u003e\n\u003ch2\u003e\n 🚤 Compatibility\n\u003c\/h2\u003e\n\u003cp\u003e\n Typically suits:\n\u003c\/p\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Volvo Penta 2003\n \u003c\/li\u003e\n \u003cli\u003e\n  Volvo Penta 2003R\n \u003c\/li\u003e\n \u003cli\u003e\n  Volvo Penta D2003AG\n \u003c\/li\u003e\n \u003cli\u003e\n  Volvo Penta 2003D\n \u003c\/li\u003e\n \u003cli\u003e\n  Volvo Penta 2002AG\n \u003c\/li\u003e\n \u003cli\u003e\n  Volvo Penta 2002B\n \u003c\/li\u003e\n \u003cli\u003e\n  Volvo Penta 2002BG\n \u003c\/li\u003e\n \u003cli\u003e\n  Volvo Penta 2002D\n \u003c\/li\u003e\n \u003cli\u003e\n  Volvo Penta 2003B\n \u003c\/li\u003e\n \u003cli\u003e\n  Volvo Penta 2002\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n \u003cli\u003e\n  \u003cstrong\u003e\n   Engine Family:\n  \u003c\/strong\u003e\n  D\n \u003c\/li\u003e\n \u003cli\u003e\n  \u003cstrong\u003e\n   Serial Range:\n  \u003c\/strong\u003e\n  SN2300032620-\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n ⚙️ Key Features\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  For engines from serial number 2300032620 onwards\n \u003c\/li\u003e\n \u003cli\u003e\n  Supersedes 840741\n \u003c\/li\u003e\n \u003cli\u003e\n  3.291 kg\n \u003c\/li\u003e\n \u003cli\u003e\n  10 applications on the D series\n \u003c\/li\u003e\n \u003cli\u003e\n  Shell-and-tube, closed coolant to raw water\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 🔌 Function\n\u003c\/h2\u003e\n\u003cp\u003e\n Transfers heat from the engine coolant to the raw water passing through it, so the engine runs at temperature without the coolant circuit being open to sea water.\n\u003c\/p\u003e\n\u003ch2\u003e\n ⚠️ Common Signs of Failure\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Engine running hot, especially under sustained load\n \u003c\/li\u003e\n \u003cli\u003e\n  Coolant loss with no external leak, or oil traces in the coolant\n \u003c\/li\u003e\n \u003cli\u003e\n  Raw water discharge reduced or intermittent at the exhaust outlet\n \u003c\/li\u003e\n \u003cli\u003e\n  Tube stack blocked with impeller debris, scale or weed on removal\n \u003c\/li\u003e\n \u003cli\u003e\n  Corrosion, weeping or pinholing at the end caps or the tube stack\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  Check the engine serial number before ordering — this exchanger is listed from 2300032620 onwards\n \u003c\/li\u003e\n \u003cli\u003e\n  Renew the end cap seals and check the anode when the exchanger is off\n \u003c\/li\u003e\n \u003cli\u003e\n  Find where the impeller debris went before refitting, and inspect the raw water pump at the same time\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 🔄 Supersession \u0026amp; Cross Reference\n\u003c\/h2\u003e\n\u003ch3\u003e\n OEM Supersession Chain\n\u003c\/h3\u003e\n\u003cul\u003e\n \u003cli\u003e\n  859360 → Supersedes 840741\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\n Aftermarket \/ Verified Equivalents\n\u003c\/h3\u003e\n\u003cul\u003e\n \u003cli\u003e\n  MR COOL: MRC840741\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 📦 Condition\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Genuine Volvo Penta part\n \u003c\/li\u003e\n \u003cli\u003e\n  Brand new\n \u003c\/li\u003e\n \u003cli\u003e\n  Supplied in original or equivalent packaging\n \u003c\/li\u003e\n\u003c\/ul\u003e\n","brand":"Volvo Penta","offers":[{"title":"Default Title","offer_id":53379678634276,"sku":"804996N","price":3555.52,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0994\/8115\/7924\/files\/original_ee8ab172-fcf5-4a54-a275-928814a1496c.jpg?v=1788097144","url":"https:\/\/www.sawleysautoandmarine.com.au\/products\/859360-heat-exchanger-genuine-volvo-penta","provider":"Sawley's Auto and Marine","version":"1.0","type":"link"}
