- [Quick Leak Detection for Smog Check] Over 60% of OBD2 issues come from hidden leaks in EVAP, exhaust, intake, vacuum, and fuel systems—often triggering the check engine light and causing failed emissions tests. Quickly pinpoint leaks before they become costly problems. Save time, avoid unnecessary repairs, and pass your Smog Check with confidence.
- [Dual Modes for Effective Leak Detection] Tackle any leak with confidence. Air Mode quickly pressurizes the system to reveal large, obvious leaks—great for saving time on initial checks. Switch to Smoke Mode to find smaller or hidden leaks in EVAP, intake, or vacuum lines with pinpoint accuracy. Whether you’re doing quick diagnostics or a full inspection, the ST203 gives you reliable results without the guesswork.
- [Built-In Air Pump, No Extra Tools Needed] With integrated air generation, this EVAP smoke machine starts producing smoke in just 10 seconds—no external air compressor required. Weighing only 5.5 lbs and featuring simple one-button operation, it’s perfect for quick, on-the-go diagnostics in garages, shops, or driveways.
- [Real-Time Leak Severity Check] Equipped with a precision pressure gauge and flow meter provide real-time readings, allowing you to instantly gauge the severity of any leak which you can decide what’s urgent and what’s not. Whether you’re a seasoned mechanic or a DIY enthusiast, get professional-grade diagnostics.
- [Smart Overheat Protection] Unlike other smoke leak detectors that shut down when overheating, the ST203’s smart heat pump frequency reduction automatically lowers the heating frequency as temperatures rise, keeping your work continuous and safe. Built-in safeguards protect your car and extend tool life.
- [Universal Compatibility with Easy Sealing] Includes 23 full-size stoppers, an intake adapter cone, and a rubber bladder to ensure tight seals on EVAP, turbo, exhaust, and more. Compatible with most 12V vehicles including cars, SUVs, minivans, and light-duty trucks. No more searching for the right adapter, just plug, seal, and start diagnosing.
- [DIY-Friendly and Easy to Use ] Just add smoke fluid not included, connect to 12V power, and start testing—no setup headaches. Whether you’re chasing an EVAP code or troubleshooting vacuum leaks, ST203 delivers reliable results every time.
