Leak detector Ancel S3000 — automotive diagnostics device for engine and cooling system leak detection

The Ancel S3000 diagnostic leak detector is a compact tool for locating leaks in vehicle systems using smoke or compressed air. Designed for EVAP, turbo, EGR, intake, fuel, cooling, exhaust and vacuum systems, the unit integrates a pressure gauge, flow meter and separate mode controls to support quick diagnosis without disassembly. Its rugged metal housing, built-in oil level indicator and accessories make it suitable for workshop use.

Advantages

The device offers two independent operation modes—Smoke and Air—with separate buttons to activate the smoke generator or air pump as required. A dense, stable smoke output makes even small leaks visible after adding 20 ml of test oil. Front-mounted PSI pressure gauge and LPM flow meter with a flow control knob provide precise control and allow assessment of leak size in real time. The compact 185 × 130 × 85 mm metal housing includes a hanging hook, Velcro strap and thermal protection that shuts the unit down above 75°C; the system is frost-resistant down to -20°C. Integrated oil level indication and included accessories allow immediate use in the workshop.

How to use

Fill the smoke generator with approximately 20 ml of the recommended test oil, connect the power clamps to a 12 V car battery and attach the hose and appropriate adapter to the system under test. Choose Air or Smoke mode using the dedicated buttons and adjust flow with the front knob while monitoring the pressure gauge (PSI) and flow meter (LPM). Direct the smoke outlet toward the inspection area to reveal leaks; observe gauge behavior for pressure drops to estimate leak severity. After testing, turn off the device, disconnect hoses and store accessories in a dry place.

Recommendations

Use only approved smoke test fluid and adapters that match the tested system. Ensure good ventilation when using smoke mode and avoid inhalation. Do not operate the device if its temperature warning indicates overheating; allow it to cool before further use. Regularly check the oil level and inspect hoses and adapters for damage before each test.
