Garrett 842483-5002S Turbocharger Assembly

The Garrett 842483-5002S is a GT17 frame size turbocharger utilizing the GTC1549VZ variable nozzle turbine (VNT) configuration. Designed for the SAIC SC28R 2.8-liter diesel engine, this unit integrates a water-cooled center housing rotating assembly (CHRA) and an electronic VNT actuator (reference 797862-0027). The compressor wheel features extended tip technology for improved efficiency at high pressure ratios. The turbine housing incorporates a flanged inlet and outlet specific to the SAIC Maxus T60 pickup truck exhaust manifold layout. This assembly serves as a direct replacement for the original equipment turbocharger, requiring no modifications to oil feed, drain, or coolant lines. Professional installation with prime oil feed and actuator calibration verification is mandatory.
