About This Remanufactured Mitsubishi Turbo — GM 1.4L Applications Part number 49180-04052 is the Mitsubishi turbocharger used across GM 1.4L turbocharged gasoline applications from 2010 through 2019, including the Chevrolet Cruze, Chevrolet Sonic, Chevrolet Trax, and Buick Encore. These small-displacement turbocharged engines became extremely popular for their combination of fuel efficiency and peppy performance — but the 1.4L turbo operates at very high shaft speeds to compensate for the engine size, which accelerates bearing wear, particularly in vehicles that do not receive regular oil changes. Common failure signs include oil consumption, blue smoke at startup (turbine seal failure), and whistling or grinding noise from the turbo. This remanufactured unit is rebuilt at PT Turbo in San Bernardino, California, with new bearings and seals throughout. Remanufacturing Process Full disassembly, cleaning, and dimensional inspection New journal bearings and thrust bearing Compressor and turbine piston ring seals replaced CHRA balanced before final assembly Oil Maintenance Is Critical on the 1.4L The Mitsubishi 49180-04052 turbo is extremely sensitive to oil quality and change intervals. Before installing any replacement turbo, flush the oil system and install fresh oil and a new filter. Restricted oil passages from old oil or sludge will destroy a replacement unit prematurely. PT Turbo recommends a 5-minute idle period after startup before driving hard to allow full oil pressure to reach the bearings. Contact our San Bernardino shop if you have questions about installation or pre-oiling procedures.
