Source: r/AskMechanics (score 0, 7 comments) Topic: belt/pulley seizure Models discussed: 451 Solution status: unclear

Problem: Smart Fortwo 451 MHD 2013 has a seized component in the belt drive system; belt turns but a pulley remains stationary, raising concern about engine seizure.

Solution: Top comment identifies a seized pulley visible in the video where belt turns but pulley doesn't. Suggested diagnostic: remove belts and attempt to crank engine to determine if motor is locked or if a specific pulley is seized.

Key facts: - Belt is turning but at least one pulley is not rotating, indicating mechanical seizure - Engine may not be seized; problem appears localized to belt drive system component - Diagnostic approach: remove belt(s) and test if engine cranks to isolate seized component
