Evap Smoke Machine

Smoke Leak Detector

【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
【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.
Customers find the smoke machine to be a quality tool that’s well worth the price, particularly appreciating its effectiveness in identifying leaks in exhaust flex couplings and fuel systems. The device comes with a great selection of adapters, making it a must-have for home mechanics. However, the smoke output receives mixed feedback – while some say it creates smoke perfectly, others report very little smoke production. Additionally, the air supply aspect is problematic, as customers need an external compressor to operate the unit, and durability is also mixed, with some saying it’s built well for long-term use while others report it breaking easily.
