3804626 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 it pairs with part 3801626, which is the number to quote for the exchange unit itself. It is one of 8 engine cores running through this block, and nothing published against them separates one from another, so order the number that matches the engine actually coming off rather than working from the description.

⚙️ Key Features

• Core deposit line, not an engine you can fit
• Pairs with part 3801626, the exchange unit it belongs to
• Refunded when the old engine is returned
• One of 8 engine cores 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 is the complete power unit, supplied built up to replace a worn or damaged engine rather than repairing it in the boat.

⚠️ 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
• Oil consumption and blue smoke, with the engine down on power and slow to start
• Knocking from the bottom end, or a rattle from the valve gear that comes straight back after adjustment
• Oil and coolant mixing, showing as emulsion under the filler cap or a film on the coolant
• On strip-down, worn bores and bearings, or a cracked block that puts repair beyond economic sense

🛠️ Service Notes

• The charge is refunded when the worn engine is returned, so keep the old unit and arrange the return collection when the order is placed rather than scrapping it
• Ordering this number on its own supplies no part - it goes on the order beside the exchange unit, part number 3801626
• An engine core covers the complete unit where the longblock and shortblock cores in this block cover progressively less of it, so establish which build is being exchanged before the deposit is raised.

📦 Condition

• Refundable core deposit - not a physical part
