3805120 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 one is returned. Nothing ships against this line on its own; it is an accounting entry that sits beside the unit on the order. Under Volvo Penta's core numbering the unit it belongs to takes part number 3802120, which is the number to quote for the turbocharger itself, and we list that number as an exchange turbocharger.Eighteen of the 60 turbocharger cores in this run are in the same position, and with no note, variant or fitment published against any of them there is nothing to tell one from another on paper, so order strictly by the number that matches the unit coming off.

⚙️ Key Features

• Core deposit line, not a turbocharger you can fit
• Paired exchange unit is part number 3802120
• Refunded when the old turbocharger is returned
• Inlet and Exhaust System group

🔌 Function

As a line item it carries the refundable core charge on the exchange; the turbocharger itself drives a compressor wheel off the exhaust gas, boosting inlet pressure so the engine makes its power without smoking.

⚠️ 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
• Power falling away after a few minutes at cruise, with exhaust temperature climbing
• Knocking or rattling from the turbo at low revs
• A shaft with free play, or wheels that will not spin freely by hand
• Soot or oil around the compressor outlet joint

🛠️ 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 3802120
• Check the exhaust for back pressure and the inlet for restriction before fitting, as either will shorten the life of the replacement

📦 Condition

• Refundable core deposit - not a physical part
