3804569 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 3801569, which is the number to quote for the component itself. It is one of 7 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 3801569
• 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
• Oil weeping from the housings, or oil found standing in the charge pipework
• On strip-down, play felt at the shaft, blade tips rubbed on the housing and a coked or scored bearing

🛠️ 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 3801569
• Cure what killed the old one before the exchange unit goes on, since a choked air filter, a restricted oil feed or a blocked drain will finish the replacement the same way

📦 Condition

• Refundable core deposit - not a physical part
