# 21906630 Turbocharger | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta turbocharger built to the Holset HE500WG / 4031291H specification for TAD1351VE-TAD1353VE engines. Compressor, turbine and wastegate calibration are engine-rating specific and must match the complete turbo identification.

## 🚤 Compatibility

Typically suits:

-   Volvo Penta TAD1371-75VE
-   Volvo Penta TAD1351-53VE

-   **Engine Family:** TAD

## ⚙️ Key Features

-   Engine-specific compressor and turbine match
-   Calibrated wastegate / actuator where fitted
-   Oil-lubricated high-speed bearing system
-   Factory flange and housing orientation
-   Intake, exhaust and lubrication systems must be verified

## 🔌 Function

Uses exhaust energy to compress intake air, increasing air mass, torque and engine power while the wastegate controls maximum boost.

## ⚠️ Common Signs of Failure

-   Low boost, slow acceleration or power loss
-   Blue/black smoke or increased oil consumption
-   Siren, scraping or bearing noise
-   Oil leakage into intake or exhaust
-   Wastegate seizure, actuator fault or over/underboost

## 🛠️ Service Notes

-   Find and fix the cause before fitting a replacement — a restricted air intake, a dirty or partly blocked oil feed, a poor oil drain or debris loose in the exhaust will destroy the new turbocharger as quickly as it did the old one
-   Renew or thoroughly flush the oil feed and drain lines, fit new sealing washers and gaskets, and change the engine oil and filter at the same time
-   Prime the bearing housing with clean engine oil through the feed connection while turning the compressor wheel by hand, before the feed pipe is connected
-   Check both wheels spin freely without touching their housings, and that the inlet and exhaust joints are clean and true so nothing can be drawn or blown through
-   After starting, let the engine idle so oil reaches the bearings before any load is applied, and idle it again to cool the bearings before shutting down after a hard run
