Kedite Automotive Smoke Machine Leak Detector 12V 19PSI — Dual-Mode Smoke & Air Pump for EVAP, Intake, Exhaust

The Kedite Automotive Smoke Machine is a compact 12V leak detector that uses a built-in 19 PSI pump and visible smoke to locate leaks across EVAP, vacuum, intake, exhaust and other vehicle pipe systems.

Whether you work on cars, ATVs, motorcycles, boats or light trucks, this all-in-one diagnostic unit combines vacuum and smoke modes to reveal hard-to-find leaks quickly. It runs from a DC 12V supply, accepts standard test oil, and shuts down automatically if it overheats, making it suitable for mobile mechanics and home DIYers alike.

How does the dual-mode design find different types of leaks?

The Kedite unit offers an air (vacuum/pressure) mode and a smoke mode to tackle a wide range of leak scenarios. Air mode pinpoints leaks by pressurizing a system and listening for escaping air; smoke mode visually reveals leak locations when smoke escapes from cracks, seals or connectors.

• Air mode: injects air to detect audible leaks in pipes and fittings.
• Smoke mode: generates visible smoke to trace leaks in EVAP, intake, exhaust systems.
• Use smoke for small or hidden leaks that aren’t obvious by sound.
• Switch modes quickly on the same tool—no extra equipment needed.

What vehicle systems and parts can this smoke machine test?

This tester is designed to work across most DC 12V vehicle systems, including fuel evaporation (EVAP) lines, vacuum hoses, turbo and intake plumbing, cooling, EGR and crankcase ventilation. It also works well on small engines, ATVs, snowmobiles and boats.

• EVAP leaks at canisters, purge valves, and hoses.
• Vacuum leaks at intake manifolds, gaskets and connections.
• Turbo and intercooler piping, exhaust seals and flange joints.
• Crankcase, cooling and accessory pipework for hard-to-see leaks.

How easy is it to operate and maintain during routine diagnostics?

Operation is straightforward: add the recommended test oil, clamp the unit to a 12V battery, connect hoses to the system under test, then run in the chosen mode. The compact housing and integrated pump make it portable, and built-in thermal protection prevents damage from overheating.

• Fill reservoir with ~15 ml test oil (mineral or baby oil permissible).
• Powered by DC 12V battery clips—no shop air required.
• Rated output pressure: 19 PSI, flow under 4 L/min for controlled testing.
• Automatic shutoff at high temperature (approx. 75°C/167°F) for safety.

What accessories and outcomes can a user expect after testing?

The kit includes connectors and hoses to reach most pipework; smoke will visibly mark leak points, and air mode helps isolate noisy leaks. After locating the fault, you can assess whether a seal, hose, clamp, or component requires replacement or further repair.

• Compatible connectors for common pipe diameters and fittings.
• Visible smoke pinpoints split hoses, porous seals and faulty gaskets.
• Audible air leakage identifies larger breaches and loose fittings.
• Compact kit makes field diagnostics and mobile service practical.

Who is this for: technicians, home mechanics and mobile service providers who need a portable, reliable leak-detection tool for gasoline and small diesel vehicles, recreational machines and marine applications. The Kedite smoke machine suits anyone seeking faster fault isolation without shop air, from weekend DIYers troubleshooting hard-starts and poor performance to professional garages diagnosing EVAP, vacuum and plumbing leaks.
