3804528 Engine Core | Genuine Volvo Penta Part

🔧 Product Description

Refundable core deposit raised against the exchange engine on Volvo Penta part number 3801528, listed under Engine. It is an accounting line rather than a fittable part: the charge goes on when the exchange engine is supplied and comes back off when the old engine is returned, and nothing is shipped against the deposit itself. Six engine deposits sit in this part of the block, at 3804521, 3804522, 3804523, 3804527, 3804528 and 3804535, and apart from the weight on 3804527 nothing separates them beyond the unit each is raised against.

⚙️ Key Features

• Refundable core deposit, not a fittable part
• Paired unit number 3801528
• Nothing ships against this line
• Credited back when the old engine is returned
• Listed under Engine

🔌 Function

Carries the refundable core charge on the outgoing engine rather than doing any mechanical work itself. The engine it stands against is supplied as a complete exchange assembly.

⚠️ 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, uneven running and compression down across several cylinders
• Blow-by heavy enough to push oil out of the breather
• Knocking or rumbling under load, with oil pressure falling away hot
• Coolant and oil mixing, or coolant pushed out of the expansion tank in use

🛠️ Service Notes

• The charge is credited back once the old engine is returned through the dealer; it has to go back complete and rebuildable, and a stripped, cracked or seized-solid engine can be refused or the credit cut.
• Ordering this number on its own supplies no part. It only makes sense raised alongside exchange unit 3801528, so confirm that unit is obtainable and check its exact designation before quoting.
• This part of the block runs engine, base engine, longblock and shortblock deposits side by side; those are four different builds of exchange unit and the deposits are not interchangeable, so match the wording as well as the number.

📦 Condition

• Refundable core deposit - not a physical part
