FOXWELL ST203 Smoke Machine Automotive Leak Detector, Auto Emission EVAP Diagnostic Smoke Machines with Built-in Air Pump, Pressure Gauge and Flowmeter, Vacuum Intake Exhaust Smoke Tester for Cars

• 【All-in-One Leak Detection – Find Problems Before They Cost You】Catch leaks early—before they trigger costly Check Engine Lights, failed smog tests, or unnecessary repairs. The FOXWELL ST203 automotive smoke machine features a built-in air pump that delivers dense smoke and stable pressure in seconds, with no external compressor. Compact, portable, and one-button operation make it easy for both shop technicians and DIYers to get fast, reliable answers with confidence.

• 【Dual Mode Air + Smoke – Pinpoint Leaks Without Guesswork】Handle both big leaks and micro faults with precision. Use Air Mode for quick pressure checks, then switch to Smoke Mode to visually trace tiny cracks in EVAP, intake, turbo, and vacuum systems. This step-by-step workflow eliminates guesswork, reduces teardown time, and helps you diagnose accurately the first time—saving hours of labor and repeat repairs.

• 【Stable Performance Under Heat & Pressure – Built for Real Work】Long jobs and hot engine bays won’t slow you down. Smart thermal control supports up to 10 minutes of continuous testing, then automatically resumes with no downtime—ideal for demanding EVAP leak detection tasks and intake system diagnostics. The reinforced metal housing resists heat and workshop wear, while consistent smoke output maintains accuracy from start to finish.

• 【Real-Time Gauge & Adjustable Flow – See the Problem Clearly】Know exactly what’s happening inside the system. The clear pressure gauge and adjustable flow meter provide instant feedback on pressure loss and smoke density, helping you judge leak severity and confirm repairs on the spot. Instead of replacing parts blindly, you get real data to make confident repair decisions—saving time, money, and frustration.

• 【One Tool, Wide Coverage – Designed for 12V Automotive Systems】From EVAP and intake systems to turbo, fuel, and vacuum lines, this 12V-compatible smoke tester handles the most common automotive diagnostics with ease. The included 23PCS adapter kit ensures secure, airtight connections across cars, SUVs, and light trucks. Small-footprint yet capable, it’s built for daily shop use and serious DIY diagnostics alike.

• 【Simple Setup, Safe Operation – Professional Results Made Accessible】Just add smoke fluid (NOT INCLUDED), connect to a 12V power source, and start testing—no extra tools or learning curve required. The visible fluid-level mark helps prevent overfilling for clean, controlled operation every time. Whether you’re a first-time user or an experienced technician, leak detection stays fast, safe, and stress-free.

• 【Wick-Free Heat Conduction – Cleaner & Safer Smoke Output】Unlike traditional burning-wick smoke machines, the ST203 Smoke Leak Detector uses a wick-free heat conduction design to generate cleaner, low-odor smoke. This reduces residue, improves safety, and delivers more stable smoke output for everyday EVAP and intake leak testing.
