A device for testing an engine pulley includes an elongated tubular shaft formed of two telescoping sections that are spring biased in a retracted position. A handle is disposed at a first end of the shaft and a motor driven pulley is rotatably mounted to the opposing end. When the shaft is extended against the bias of the spring, electrical contact between an external power source and the motor is established. A belt is placed about the motor driven pulley and the engine pulley to rotate the select engine pulley independently of the remaining engine pulleys allowing a user to audibly and visually determine if the pulley is malfunctioning.
