The Vevor 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 on cars, trucks, boats, motorcycles, and ATVs. Dual Air Mode and Smoke Mode help verify system sealing and then visually identify leak points while reducing smoke fluid use. Triple-gauge assistance and dual built-in air pumps provide stable airflow, clear readings, and easier diagnostics in tight engine compartments.
