Remanufactured 3791448 Volvo D16 Holset HE500VG Turbocharger

The 3791448 Turbocharger is a purpose-matched Holset HE500VG assembly for Volvo D16, Heavy-duty Volvo highway and vocational D16 applications. It is built around the exact compressor, turbine, housing, and control specification associated with part number 3791448, so fitment should be confirmed from the engine serial number and original turbo tag rather than by engine family alone.

The 3791448 HE500VG is a large-frame variable-geometry turbocharger for Volvo D16 applications. It must provide high air mass for the 16-litre engine while adjusting vane position to support response, engine braking, emissions control, and exhaust temperature management.

The size and load of the D16 make clean oil supply, unrestricted drain flow, correct crankcase pressure, and accurate actuator calibration especially important.

This is the turbo-only version and is supplied without the electronic actuator. The existing actuator should only be reused after its condition, compatibility, and calibration are verified; a worn or incorrectly indexed actuator can cause boost, vane-position, and engine-brake faults even when the turbocharger itself is sound. Turbo Centre remanufacturing begins with complete disassembly and thorough cleaning so every critical surface can be inspected. Worn bearings, seals, and service components are replaced; shaft, wheel, housing, and vane-system condition are measured; the rotating assembly is balanced; and the completed turbo is checked for smooth operation, oil sealing, and correct control movement before shipment. This process restores the unit as a complete engineered assembly rather than simply replacing the visibly damaged component.
