Key Specifications

This listing details the core identifiers for the 755042-5003S turbocharger unit. The product is classified as a complete turbocharger assembly, specifically matching the GT1749V and GTA1749MV model series.

Use the supplied OEM reference numbers 755042-9003S and 755373-0001 to help confirm fitment for your specific vehicle application. Always verify the engine code, production year, and turbo model against your existing hardware before ordering.

Technical Notes

The GT1749V and GTA1749MV model codes indicate a variable-geometry turbocharger design. Typical configuration may include VNT design and oil-cooled system (verify per application). Buyers should inspect the turbine housing vanes and compressor wheel for damage before installation. Ensure all mounting flanges align correctly with the engine manifold. Verify that the actuator related hardware moves freely without binding. Proper sealing of oil feed and drain lines is critical for stable operation. Consult technical documentation for specific torque values and gasket requirements during reassembly.
