Answer

Brief Explanations:

  1. A mechanics stethoscope is designed to listen to engine - related noises and help identify the source of the noise in the engine bay. OBD II scan tools are for diagnosing electronic issues, chassis ears are for different types of noise detection not as specific for engine bay noises, and DVOM (Digital Volt - Ohm Meter) is for electrical measurements.
  2. Jack stands are used to support a vehicle after it has been lifted by a hydraulic jack for safety, preventing the vehicle from falling. Safety cranes are for lifting heavy objects, cinder blocks are not proper safety equipment for jacks, and drive - on ramps are a different type of vehicle - lifting device.
  3. A timesert looks like a metal bushing and creates a complete seal for thread repair. A helicoil is also a thread repair insert but does not create a complete seal like a timesert. A tap is for cutting threads and a die is for threading external surfaces.

Answer:

  1. Mechanics stethoscope
  2. Jack stands
  3. a timesert
