The rupture of the vacuum hose will cause the mixture to be too thick, the idle speed will increase, the hot car will not start well, the engine will surge during acceleration, the fuel consumption will increase significantly, and the exhaust pipe will emit black smoke. 2. Blocking will cause the idle speed to drift, and the idle speed is easy to stall. 3. Air leakage in the vacuum tube will cause the engine to run weakly - 【No Air Pump】Note: AUTOOL SDT103 does not have an internal air pump. External air supply is required for use. Connect shop air supply, connect 12V vehicle power, introduce shop air to the AUTOOL SDT103 fuel leak tester, turn the Flow Dial anti-clockwise to open the air flow, switch on the power at the back of the unit, then AUTOOL SDT103 smoke machine automotive will start to generate smoke - 【External Flow Meter】You can easily control the air pressure, because the air pressure of each pipe in the car is different. If the air pressure is too high, the pipe will be damaged, and if the air pressure is too low, the leak will not be detected. Therefore, the flow meter is very important to protect your detection system more effectively. Make testing safer - 【EVAP Detection】American cars that began production in 1996 are equipped with EVAP service ports; in most American cars, the EVAP service port is usually located in the engine compartment, but the EVAP service port of some special models may be located in other locations. Open the plastic cover of the EVAP service port, then use the spool wrench to remove the check valve clockwise, then install the EVAP service port adapter, and introduce smoke from the port into the EVAP leak detection system - 【Wide Testing Range】The smoke leak detector AUTOOL SDT103 can do smoke testing of multiple systems, such as EVAP systems, Intake Systems, Cooling / EGR /Exhaust Systems, Crankcase Systems, Engine Airtightness, Vacuum Leaks, Low Pressure Turbo leaks.Applicable cars, motorcycles, snowmobiles, off-road vehicles, ATVs, light trucks and speedboats boats. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BGB41DLK | | Best Sellers Rank | #8,689 in Automotive ( See Top 100 in Automotive ) #6 in Fuel Leak Detectors | | Brand | AUTOOL | | Customer Reviews | 4.5 4.5 out of 5 stars (2,743) | | Date First Available | September 24, 2022 | | Item Weight | 4.69 pounds | | Item model number | SDT103 | | Manufacturer | AUTOOL | | Manufacturer Part Number | SDT103 | | Model | Automotive Smoke Machine | | Product Dimensions | 8.66 x 12.2 x 12.2 inches | ## Product Details - **Brand:** AUTOOL - **Item Weight:** 2.13 Kilograms - **Alarm:** Audible - **Operating Humidity:** 95 percent - **Number of Items:** 1 - **Manufacturer:** AUTOOL ## Images ![Smoke Machine Automotive Leak Detector,0-0.46PSI Evap Vacuum Smoke Diagnostic Tester,Pipeline Fuel Leakage Detector Compatible with 12V Vehicles - Image 1](https://m.media-amazon.com/images/I/61YpFef6TvL.jpg) ![Smoke Machine Automotive Leak Detector,0-0.46PSI Evap Vacuum Smoke Diagnostic Tester,Pipeline Fuel Leakage Detector Compatible with 12V Vehicles - Image 2](https://m.media-amazon.com/images/I/71QvqLwMhsL.jpg) ![Smoke Machine Automotive Leak Detector,0-0.46PSI Evap Vacuum Smoke Diagnostic Tester,Pipeline Fuel Leakage Detector Compatible with 12V Vehicles - Image 3](https://m.media-amazon.com/images/I/71EXi1D2UnL.jpg) ![Smoke Machine Automotive Leak Detector,0-0.46PSI Evap Vacuum Smoke Diagnostic Tester,Pipeline Fuel Leakage Detector Compatible with 12V Vehicles - Image 4](https://m.media-amazon.com/images/I/81VSE8mwdoL.jpg) ![Smoke Machine Automotive Leak Detector,0-0.46PSI Evap Vacuum Smoke Diagnostic Tester,Pipeline Fuel Leakage Detector Compatible with 12V Vehicles - Image 5](https://m.media-amazon.com/images/I/71Ovvpp2MmL.jpg) ## Available Options This product comes in different **Model** options. ## Questions & Answers **Q: what do i use as an air source?** A: The air compressor can provide the air source. **Q: Does it come with smoke fluid?** A: Thank you for your attention to our AUTOOL smoke tester, very sorry, our smoke tester does not contain cigarette oil, because it belongs to flammable liquid, transportation is more complicated, so you need to buy it separately, causing you inconvenience, we are very sorry, if you have any questions about the goods, please feel free to contact us, we are always here for you. **Q: What types of oil can be used?
