Which of the following tasks is NOT typically performed by an automotive technician?

An automotive technician's primary role is to diagnose, repair, and maintain vehicles. This involves technical tasks such as diagnosing engine problems, which requires a deep understanding of engine components and systems to identify issues accurately. Rebuilding engines is also a specialized skill within the technician's purview, involving disassembly, reconditioning, and reassembly of engine parts, which necessitates knowledge of mechanical workings and precision.

Changing oil and filters is a standard maintenance task that technicians perform regularly to ensure vehicle longevity and performance. This routine service helps maintain optimal engine operation by keeping it clean and lubricated.

On the other hand, driving sales of new vehicles is not a typical responsibility of an automotive technician. This task is generally associated with sales personnel at dealerships who focus on customer interaction and selling vehicles, rather than the technical and mechanical responsibilities that define a technician's role.
