3801390 Turbocharger | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured turbocharger from the Inlet and Exhaust System group, weighing 32.66 kg and listed for 1 application on TAD-series engines. In the D16 industrial tables it is the turbocharger for the build that also takes cylinder head 3801395, unit injector 3803637 and complete engine 3801966; the sister build uses turbocharger 3802140 with injector 3803638, so the injector fitted to your engine confirms which turbocharger it wants. It sits within half a kilogram of the D-series units 3801526 at 33.11 kg and 3801495 at 33.25 kg, which are different fitments. It is supplied on an exchange basis: core deposit 3804390 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.

⚠️ Common Signs of Failure

• Loss of boost and heavy black smoke under load
• Siren or whistle rising with engine speed
• Blue smoke and oil carry-over into the charge air cooler
• Exhaust leak or soot tracking at the turbine housing joints

🛠️ Service Notes

• The old turbocharger goes back as the core once the new one is fitted and the engine is running, releasing deposit 3804390
