VEVOR Automotive Smoke Machine Leak Detector, DC 12V EVAP Vacuum Diagnostic Tester with Built-in Air Pump, Pressure Gauge & Flow Meter, Dual-Mode Detector for Cars, Motorcycles, Trucks, Boats, ATVs

Automotive Smoke Leak Detector with Two Modes for Faster and Smarter Diagnosis

This automotive smoke leak detector for automotive systems saves time and smoke fluid by allowing technicians to perform diagnostics in two steps. To check for a major leak before committing to smoke, first turn on Air Mode to pressurize the system. By doing this pre-check step, you can see right away if the system is sealing properly and avoid using extra fluid.

Once Air Mode detects a leak, you can switch to Smoke Mode to see exactly where it is. It is easy to see even hard-to-reach leaks because the dense smoke moves through the system and exits at the leak. You do not have to guess with this sequential dual-mode approach. It speeds up the diagnosis process and helps you make faster, more confident repair decisions on every job.

Two Built-In Air Pumps for Stable Airflow and Dense Smoke Output

The SD716 runs on DC 12V and has two built-in air pumps that maintain consistent, high-volume airflow throughout the test cycle. With a steady flow rate of 8 L/min and an output pressure of 19–23 PSI, these pumps ensure that smoke reaches every part of the system being tested. You do not need an external compressor or other equipment to get consistent performance.

The dual-pump design produces thick smoke that penetrates engine compartments, making it easier to see where leaks are occurring. Even in tight areas, such as around turbo pipes and intake passages, the smoke spreads out completely, making it easy to see where the leaks are. This amount of smoke density makes it less likely that you will miss a small but important problem during your inspection.

Pressure Gauge and Flow Meter for Accurate Leak Detection

This automotive smoke leak detector features a pressure gauge that displays system pressure immediately. This feature lets you find large leaks immediately after pressurizing the system. You can tell there is a big hole in the system before you even add smoke because the gauge will drop suddenly.

The flow meter and adjustable flow control knob can detect small leaks that the pressure gauge might not detect. An unbroken system has a steady flow rate, whereas an unexpected rise in flow indicates a small escape point. Together, these two gauge instruments let you assess the system’s integrity at both the macro and micro levels. This feature makes your diagnosis thorough and accurate across all tests.

Wide System Coverage Across EVAP, Vacuum, Turbo, and Exhaust Line

This smoke machine can detect leaks in many car systems, including EVAP lines, vacuum hoses, intake passages, turbo piping, and exhaust systems. You can use this one tool to diagnose an EVAP code on a passenger car or a boost leak on a turbocharged engine; you do not need any other system-specific tools.

With a temperature range of -4°F to 167°F (-20°C to 75°C), the detector works well in a variety of shop settings. Its robust construction of steel, aluminum, brass, and silicone, along with a 65W power rating, makes it suitable for frequent professional use. You get a lasting tool that works with almost any pressurized system you encounter on the job.

8-Piece Sealing Kit for Versatile and Precise Leak Testing

A smoke leak detector is only as effective as its ability to seal the system being tested. VEVOR offers a complete sealing kit to ensure the system under test remains sealed. The package includes an 8-piece cap plug kit, a cone adapter, an EVAP adapter, and an inlet port fitting. These parts make it easy to quickly seal lines of different sizes and port configurations, so you can spend more time diagnosing and less time adapting.

Because so many adapters are included, you can switch from one car or system type to another without having to find compatible fittings. When it comes to openings of different shapes, the cone adapter can handle them, and the EVAP adapter ensures the connection to evaporative emission systems works properly. You do not need any other tools with this useful kit, as it comes with everything required to perform a clean, airtight test as soon as you open the box.

Automotive Smoke Leak Detector Built for Cars, Trucks, Boats, and ATVs

What the VEVOR SD716 is not is a tool for just one type of vehicle. It reliably finds leaks in cars, motorcycles, trucks, boats, and ATVs, making it a good buy for shops with a variety of vehicles and for mobile technicians. With compact dimensions of 9.4 x 6.3 x 8.3 inches and a weight of 7.7 pounds, it is easy to move between bays or to job sites.

There is a professional look to the black-and-orange build that makes it suitable for busy workshop settings. Because it requires 12V DC power, you can run it directly from a car battery or an appropriate power supply. This feature gives you options for how and where to use it. It does not matter whether you work on light passenger cars or heavy-duty trucks; this automotive smoke leak detector consistently delivers professional-grade results.
