AUTOOL Automotive Smoke Machine, EVAP System Smoke Leak Detector with Air Pump/Flow Indicator/Pressure Gauge for All DC12V Vehicles

【Why Need It】For example: 1. 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. 【Built-in Air Pump】Customers do not need to purchase additional air pumps, we use high-quality materials, after many tests, please rest assured to use. You can save more time and money. 【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. 【External Pressure Gauge】You can observe the barometer to more accurately determine whether the car pipeline is leaking. If the barometer index keeps increasing, there is no problem with your car’s pipeline. If the barometer index keeps decreasing, your car’s pipeline leaks need to be repaired, and there is a barometer test. Leakage is faster and more accurate. 【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.
