About This GT1446 Turbocharger — Chevrolet Cruze and Sonic 1.4L
This Garrett turbocharger is used in the Chevrolet Cruze and Chevrolet Sonic with the 1.4L turbocharged four-cylinder engine (LUJ/LUV). It is a small, high-speed wastegated unit: its size lets the 1.4L engine build boost quickly at low RPM for responsive city driving, and the wastegate holds boost in check at highway speeds. Because of the small turbine housing and high operating shaft speeds, oil quality and change intervals have an outsized effect on bearing longevity in this application.
This replacement GT1446 is built to fit the Cruze and Sonic 1.4L application directly. Common failure symptoms on this platform include oil consumption, blue smoke at startup, a check engine light with boost control codes, and audible whine or grinding from the turbo at idle or under light load.
Why the 1.4L Turbo Fails Prematurely
- Extended oil change intervals — small-displacement turbocharged engines need frequent fresh oil
- Low oil level operation — the 1.4L oil capacity is small; low levels affect bearing lubrication
- Immediate shutdown after hard driving — heat soak without idle-down damages seals
- PCV system issues — a failed PCV valve creates crankcase pressure that pushes oil past turbo seals
