in vehicles with cracks and leaks that result in an evap system failure, the use of a(n) ________ may be necessary to find the leaks in the system.\n\n a. smoke machine\n b. ultraviolet dye kit\n c. scan tool\n d. intrusive test

Answer

Brief Explanations:

  • A smoke machine is used to detect leaks in the EVAP (Evaporative Emission Control) system. It introduces smoke into the system, and if there are cracks or leaks, the smoke will escape, making the leak location visible.
  • An ultraviolet dye kit is more commonly used for detecting coolant or oil leaks (when combined with a UV light), not typically for EVAP system leak detection.
  • A scan tool is used to read diagnostic trouble codes and monitor system data, not for physically locating leaks in the way a smoke machine does.
  • An intrusive test would involve disassembling parts of the system, which is not the first - choice method when a non - intrusive method like a smoke machine can be used.

Answer:

A. Smoke machine
