3804754 Turbocharger Core | Genuine Volvo Penta Part

🔧 Product Description

Core deposit for a turbocharger, in the Inlet and Exhaust System group. It is the refundable charge raised against the old turbocharger when the exchange unit is bought, and it comes back once the worn turbocharger 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 3801754, which is the number to quote for the component itself. It is one of 5 turbocharger cores running through this block, and nothing published against them separates one from another, so order the number that matches the turbocharger actually coming off rather than working from the description.

⚙️ Key Features

• Core deposit line, not a turbocharger you can fit
• Belongs with the exchange unit, part number 3801754
• Refunded when the old turbocharger is returned
• Not separable from the other turbocharger cores here, so order by part number
• Inlet and Exhaust System group

🔌 Function

As a line item it carries the refundable core charge on the exchange; the turbocharger itself uses exhaust energy to drive a compressor that forces extra air into the engine, raising the power it makes for its size.

⚠️ Common Signs of Failure

• This is a deposit line and has nothing to fail in itself; the signs below are what normally condemns the turbocharger being exchanged
• Whistling or siren-like note from the turbo that rises and falls with engine speed
• Boost down, with the engine smoky and short of power under load
• Blue smoke and oil found in the charge air pipework or the intercooler
• On removal, shaft play in and out or up and down, rubbed wheel tips and a coked centre housing

🛠️ Service Notes

• The charge is refunded when the worn turbocharger 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 3801754
• Find out why the old one failed before the exchange unit goes on, since a blocked oil drain, a starved feed or a dirty air filter will take the replacement out the same way

📦 Condition

• Refundable core deposit - not a physical part
