# 3804405 Turbocharger Core | Genuine Volvo Penta Part

## 🔧 Product Description

Core deposit for a Volvo Penta turbocharger, from the Inlet and Exhaust System group. It is an accounting line rather than a fittable part: the refundable charge raised against the old turbocharger when a replacement is supplied on exchange, credited back once that worn unit is returned. Ordering it supplies nothing in itself. It is raised against unit 3801405. Core numbers in this series run three thousand above the unit they belong to, so the deposit and the unit are read as a pair.

## ⚙️ Key Features

-   Refundable core deposit on a turbocharger, not a fittable part
-   Credited back on return of the old turbocharger
-   Pairs with unit 3801405, three thousand below this core number

## 🔌 Function

Holds the refundable deposit raised against the old turbocharger when a replacement is bought on exchange, and releases it as a credit when that unit is returned. It does no mechanical work. The turbocharger itself forces air into the engine under pressure, driven by energy recovered from the exhaust stream.

## ⚠️ 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
-   Blue or black smoke, with oil found standing in the charge pipes or intercooler
-   A whine, whistle or siren note that rises and falls with boost
-   Boost pressure down, the engine slow to pull and short of its usual power
-   Shaft play felt at the compressor wheel, or blade tips that have rubbed the housing

## 🛠️ Service Notes

-   The deposit is refunded when the old turbocharger is sent back, so return it complete and as it came off - the credit depends on the core being fit to rebuild, and a stripped or broken-up unit can lose it
-   Ordering this line on its own supplies no part. It has to go on the order alongside unit 3801405, which is the item that actually ships
-   Several turbocharger cores in this block read identically on the line, so the paired unit number is the only dependable way to tell them apart - order by number

## 📦 Condition

-   Refundable core deposit - not a physical part
