3805390 Engine Core | Genuine Volvo Penta Part

🔧 Product Description

Core deposit for an engine, in the Engine group. It is the refundable charge raised against the old engine when the exchange unit is bought, and it comes back once the worn engine 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 3802390, which is the number to quote for the engine itself. It is one of 21 engine cores listed here, the block 3805389 to 3805405 together with 3805408 and the run 3805416 to 3805418, and nothing published against them separates one from another, so order the number that matches the engine actually coming off.

⚙️ Key Features

• Core deposit line, not an engine you can fit
• Belongs with the exchange unit, part number 3802390
• Refunded when the old engine is returned
• One of 21 engine cores listed here, so order by part number
• Engine group

🔌 Function

As a line item it carries the refundable core charge on the exchange; the engine itself burns the fuel it is given and turns that energy into the shaft rotation that drives the vessel.

⚠️ Common Signs of Failure

• This is a deposit line and has nothing to fail in itself; the signs below are what normally condemns the engine being exchanged
• Hard starting on low compression, with heavy blow-by out of the breather
• Knocking or rumbling from the bottom end, or oil pressure falling away when hot
• Coolant and oil finding their way into each other, with an emulsion on the filler cap or steam at the exhaust
• Oil consumption and exhaust smoke rising while power falls away against the same load

🛠️ Service Notes

• The charge is refunded when the worn engine is returned, so keep the old unit and send it back rather than scrapping it
• Ordering this number on its own supplies no part - it goes on the order beside the exchange unit, part number 3802390
• Establish which ancillaries the exchange engine is supplied with before it arrives, and strip anything you are keeping off the old engine before it goes back

📦 Condition

• Refundable core deposit - not a physical part
