Why do you need it? 1. The breakage of the vacuum hose causes the mixture to be too thick, the idle speed increases, the hot car does not start well, the engine shoots when accelerating, the fuel consumption increases significantly and the exhaust emits black smoke. 2. Blocking causes the idle speed to drift, and the idle speed can be easily choked. 3. An air leak in the vacuum line leads to a weak engine running. 【No Air Pump】Note: The AUTOOL SDT103 does not have an internal air pump. An external air supply is required for use. Connect the workshop air supply, connect the 12V vehicle power supply, direct the workshop air into the AUTOOL SDT101 fuel leak tester, turn the flow regulator counterclockwise to open the airflow, turn on the power on the back of the device, then the AUTOOL SDT101 smoke machine automotive will begin. 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 the exam safer EVAP detection: American cars produced from 1996 are equipped with EVAP service connections; in most American cars, the EVAP service port is usually located in the engine compartment, but the EVAP service port of some special models can be located in other places. Open the plastic cover of the EVAP service port, remove the check valve with the wrench clockwise, install the adapter for the EVAP service port, and feed 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 airtightness, vacuum leaks, low pressure turbo leaks. Applicable cars, motorcycles, snowmobiles, off-road vehicles, ATVs, light commercial vehicles and speedboats
