3804770 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 3801770. We list that number as a remanufactured engine. It is one of 13 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
• Belongs with the exchange unit, part number 3801770
• Refunded when the old engine is returned
• Not separable from the other 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, turning the fuel's energy into shaft power for the drive or propeller.

⚠️ 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
• Blue or white smoke that will not clear, with oil or coolant disappearing between services
• Oil pressure low or falling away hot, with a rumble or knock from the bottom end under load
• Hard starting and lost power, with compression down on one or more cylinders
• On strip-down, scored bores, picked-up main or big-end shells, or a cracked block or eaten head face

🛠️ 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 3801770
• Find and cure what killed the old engine, whether overheating, contaminated fuel or oil or a failed cooler, before the exchange unit is run, and fit fresh oil, filters and coolant at the same time

📦 Condition

• Refundable core deposit - not a physical part
