This automotive smoke machine leak detector is designed to help locate hidden leaks in vehicle systems quickly and accurately. It supports testing for EVAP lines, vacuum hoses, intake passages, turbo piping, and exhaust systems. Dual Air and Smoke modes help verify system sealing first and then visually pinpoint leak points while reducing smoke fluid use. Built-in dual air pumps provide steady airflow and dense smoke for easier diagnostics in tight engine compartments. It is suitable for cars, motorcycles, trucks, boats, and ATVs.
