The oil cooler transfers heat from engine oil into the raw water cooling circuit, keeping oil temperatures within operating range and protecting the engine under sustained load. At $1,399, this is a high-value component — always confirm fitment by engine model and serial number before ordering.\u003c\/p\u003e\n\n\u003ch3\u003eCompatible Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eVolvo Penta diesel inboard engines — specific models confirmed by serial number\u003c\/li\u003e\n\u003cli\u003eVerify fitment using your engine model designation and serial number on the engine block ID plate\u003c\/li\u003e\n\u003cli\u003eCross-reference against the Volvo Penta parts diagram for your engine before ordering\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 21657814\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Engine oil cooler (heat exchanger)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem:\u003c\/strong\u003e Oil cooling \/ thermal management\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e OEM marine-grade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e Approx. 6 kg (estimated)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\n\u003cp\u003eThis oil cooler is most commonly ordered during a major engine overhaul or after a cooling system failure that allowed oil temperatures to spike. It’s also replaced when the cooler develops an internal leak — which can allow raw water to contaminate the engine oil or oil to enter the cooling circuit. Either condition requires immediate attention. Because this is a high-value part, we strongly recommend confirming your engine serial number and cross-referencing the parts diagram before placing your order. Incorrect fitment returns on large cooling components are costly and time-consuming.\u003c\/p\u003e\n\n\u003ch3\u003eService Interval\u003c\/h3\u003e\n\u003cp\u003eInspect during major engine service intervals. Replace immediately if internal leakage is suspected (milky oil, coolant loss without external leak, or overheating under load). Proactive replacement is recommended during full engine overhauls on high-hour engines.\u003c\/p\u003e\n\n\u003ch3\u003eSigns This Part Needs Replacement\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMilky or contaminated engine oil (water intrusion)\u003c\/li\u003e\n\u003cli\u003eUnexplained coolant loss without visible external leak\u003c\/li\u003e\n\u003cli\u003eEngine overheating under sustained load\u003c\/li\u003e\n\u003cli\u003eOil in the cooling circuit\u003c\/li\u003e\n\u003cli\u003eScheduled engine overhaul on high-hour diesel\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical FAQ\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How do I know if my oil cooler has failed?\u003c\/strong\u003e\u003cbr\u003e\nThe most common signs are milky engine oil (indicating water contamination) or unexplained coolant loss.
