3805173 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 3802173, 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 3802173
• 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 uses the energy left in the exhaust to drive a compressor, forcing more air into the cylinders so the engine can burn more fuel and make more power.

⚠️ 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
• Oil standing in the inlet ducting and a smoky exhaust that clears as the engine warms
• Whistling or hissing from the turbo that grows louder with throttle
• Excessive end float or radial play when the shaft is checked
• Coked oil in the bearing housing and a discoloured oil feed line

🛠️ Service Notes

• Returning the worn turbocharger releases the deposit, so plan the return at the time of ordering rather than leaving the old unit on the bench
• Ordering this number on its own supplies no part; it goes on the order beside the exchange unit, part number 3802173
• Change the engine oil and filter at the same time, and check the crankcase breather is clear before the unit is fitted

📦 Condition

• Refundable core deposit - not a physical part
