The Autool SDT203 Car Smoke Leak Detector is a compact and effective diagnostic tool engineered to detect leaks in a variety of automotive systems. It produces dense smoke in under 10 seconds at a flow rate of 6 to 7 liters per minute, with a working pressure of up to 17.4 PSI (approximately 1.2 bar), making it ideal for EVAP systems, intake and exhaust lines, fuel tanks, cooling systems, and crankcases. The unit features a built-in air pump, eliminating the need for an external air source, and includes a pressure gauge, flow meter, and oil-level window for real-time monitoring and precise leak detection. For added safety and durability, the SDT203 is equipped with smart protections that automatically shut off the device if internal temperatures exceed 75°C or drop below -20°C. Powered by a standard 12V vehicle battery, it is lightweight and portable, with a convenient hook for hands-free use under the hood. The device is backed by a three-year warranty, providing reliability and long-term support for both professional and DIY automotive technicians.
