Kedite Automotive Smoke Machine 12V Leak Detector — 19 PSI Built‑In Pump & Flow Meter for EVAP, Intake, Exhaust Systems

The Kedite Automotive Smoke Machine is a portable 12V leak detector that generates visible smoke and 19 PSI pressure to quickly locate leaks in EVAP, intake, cooling, exhaust, and other vehicle pipe systems.

This compact, all-in-one diagnostic unit combines a built-in air pump, flow meter, and dual-mode operation so you can test vacuum and smoke-sensitive systems on cars, trucks, motorcycles, ATVs, boats and more. With straightforward setup and an overheat protection feature, the unit is designed for both DIY enthusiasts and professional technicians who need a fast, reliable way to find hard-to-see leaks that affect performance and emissions.

How does the Kedite smoke machine find leaks in different vehicle systems?

The unit uses two complementary detection methods: pressurized air to listen for escaping air and visible smoke to pinpoint cracks, seals or disconnected hoses. Using either mode makes it easier to identify small or intermittent leaks that a visual inspection would miss.

• Air mode pressurizes lines up to 19 PSI so you can hear and feel leaks.
• Smoke mode produces dense smoke that escapes at the leak location for visual identification.
• Suitable for EVAP systems, intake manifolds, turbo hoses, EGR and exhaust ports.
• Built-in flow meter helps assess the severity and approximate size of a leak.

What steps are required to set up and use this leak diagnostic tool?

Setup takes only a few steps: add test oil, connect the unit to a 12V source, attach the appropriate adapter to the target system, and select air or smoke mode. The straightforward controls and included fittings make it convenient to operate in the garage or at the roadside.

• Pour about 15 ml of mineral or baby oil into the smoke chamber before use.
• Connect the alligator clips to a DC 12V vehicle battery or equivalent power supply.
• Select vacuum (air) or smoke mode depending on the diagnosis needed.
• Monitor the flow and inspect joints, seals and hoses for escaping smoke or sound.

How safe and durable is the Kedite leak detector for regular workshop use?

The Kedite unit includes overheat protection that automatically shuts the device down if internal temperature exceeds safe limits, protecting the operator and the tool. Its compact design and integrated pump eliminate the need for external shop air, making it practical for frequent field or workshop use.

• Overheat protection triggers at about 75°C (167°F) and alerts with an indicator light.
• Integrated air pump delivers up to 19 PSI and rated flow of less than 4 L/min.
• Rugged housing and simple controls for repeated use and transportability.
• Designed for DC12V vehicles including cars, SUVs, ATVs, motorcycles and boats.

Which leaks and symptoms can this tool help diagnose?

This smoke machine is built to help locate the physical sources behind symptoms such as rough idle, hard starting, poor fuel economy, loss of power or unusual exhaust behavior. It targets a wide range of leak points that commonly cause drivability and emissions problems.

• EVAP canister, purge valve and fuel system leaks that cause check-engine lights.
• Intake or turbo hoses and gasket leaks that reduce engine power or efficiency.
• Vacuum line cracks, worn seals, grommets and connectors that cause irregular idle.
• Exhaust or EGR leaks that affect emissions and performance.

Who this is for: the Kedite Automotive Smoke Machine is aimed at vehicle owners, independent mechanics and service shops that need a compact, transportable diagnostic tool to quickly identify leaks across a wide range of engines and pipe systems. If you perform regular troubleshooting on cars, light trucks, ATVs, motorcycles or watercraft and want an efficient, dual-mode way to locate leaks without specialized shop air, this unit is a practical addition to your toolset.
