The Sealey VS870 Smoke Diagnostic Tool is designed for professional automotive technicians who need to identify hidden leaks in vehicle systems, including vacuum, cooling, and exhaust components. It offers the key benefit of rapid, visual leak detection through low-pressure smoke generation, significantly reducing diagnostic time. While highly efficient, users should note that the device requires an external source of mineral oil, which is not included with the kit.

You should use standard mineral oil specifically designed for smoke diagnostic machines.
It is designed for air intake, cooling, evaporation, fuel, exhaust, and vacuum systems. Always verify that the system is not pressurized before testing.
No, the device connects to your vehicle's existing 12V battery for power.
The tool uses workshop air pressure; please ensure you do not exceed the pressure limits of the specific vehicle component being tested.
Select the cone that best fits the diameter of the pipe or hose opening you are sealing to ensure an airtight seal during the smoke test.
Check the mineral oil level in the reservoir and ensure the 12V battery connection is secure.
Verify that the workshop air supply pressure is stable and check that the flow control valve is adjusted correctly.
Check the vehicle battery voltage and inspect the power leads for any visible damage or loose connections.
To begin, connect the tool to a 12V DC power source, such as a vehicle battery. Fill the reservoir with high-quality mineral oil, ensuring not to exceed the fill line. Connect the workshop air supply to the air inlet, select the appropriate blanking cone from the four provided sizes (10-45mm, 30-65mm, 50-85mm, or 70-100mm) to seal the system under test, and press the power button to initiate smoke production. Regularly inspect the hoses for cracks and ensure the oil reservoir remains clean. When not in use, store the unit in a dry place, ideally within the original packaging to protect the sensitive internal components and keep the blanking cones organized.
