The 2001 G30 came with a variety of engine options including a 4.3L V6, a 5.0L V8, a 5.7L V8, and a 7.4L V8 engine. The 5.7L V8 produced around 255 horsepower and 330 lb-ft of torque.

Summary

The 2001 Chevrolet G30, while reliable for its time, is now showing its age. The most common issues revolve around oil leaks, transmission problems (slipping/hard shifting), suspension wear (ball joints, tie rods, leaf springs), and electrical component failures (alternator, fuel pump). Rust is also a significant concern, particularly in areas with road salt. Repair costs can range from relatively inexpensive fixes like replacing gaskets to more significant expenses like transmission rebuilds or rust repair. Before purchasing, have a mechanic thoroughly inspect the vehicle for these common issues to avoid costly surprises.
