Autool SDT103 Car leak detector, smoke diagnosis, vacuum, Evap diagnosis tester, pipe fuel compatible with 12 V vehicles

【Why You Need It】1. A vacuum hose break will make the mixture too thick, increase the idle speed, cause a hot car to have trouble starting, cause the engine to stumble during acceleration, significantly increase fuel consumption, and produce black smoke from the exhaust pipe. 2. A lock will cause the idle speed to deviate and make the idle speed prone to stalling. 3. Air leaks in the vacuum tube will cause the engine to run weakly. 【No Air Pump】Connect the shop air supply, plug in the vehicle's 12V power, insert the shop air into the SDT101 fuel leak tester, turn the flow dial counterclockwise to open the airflow, connect the power at the back of the unit, and the automotive smoke machine will start generating smoke. 【External Flow Tester】You can easily control the air pressure, as the air pressure in each tube of the car is different. If the air pressure is too high, the hose will be damaged, and if the air pressure is too low, the leak will not be detected. Therefore, the flow meter is very important for more efficiently protecting your detection system. 【EVAP Detection】The EVAP service port is usually located in the engine compartment, but the EVAP service port on some special models may be placed elsewhere. Open the plastic cover of the EVAP service port, then use the coil key to remove the check valve clockwise, install the EVAP service port adapter, and insert the smoke from the port into the EVAP leak detection system. 【Wide Testing Range】The smoke leak detector can test smoke from multiple systems, such as EVAP systems, intake systems, cooling/EGR, exhaust systems, crankcase systems, engine sealing, vacuum leaks, and low-pressure turbo leaks. Vehicles applicable include cars, motorcycles, snowmobiles, ATVs, light trucks, and speedboats.
