AUTOOL Automotive Smoke Machine, Evap System Leak Detector, Machin with Adapter

【Why You Need It】 1. A broken vacuum hose causes the mixture to be too rich, the idle speed to increase, hot vehicles to have poor starting, engine backfiring during acceleration, significant fuel consumption increase, and black smoke from the exhaust. 2. Blockages cause the idle speed to fluctuate and the idle may easily stall. 3. An air leak in the vacuum line leads to weak engine performance. 【No Air Pump】Note: The AUTOOL SDT103 does not have an internal air pump. External air supply is required for use. Connect the workshop air supply, connect the 12V vehicle power supply, channel the workshop air into the AUTOOL SDT101 fuel leak tester, turn the flow regulator counterclockwise to open the airflow, switch on the power at the back of the device, then the AUTOOL SDT101 automotive smoke machine will start generating smoke. 【External Flow Meter】You can easily control the air pressure because the air pressure varies in every tube of the car. If the air pressure is too high, the tube may be damaged; if the air pressure is too low, the leak may not be detected. Therefore, the flow meter is very important to protect your detection system more effectively and make testing safer. 【EVAP Detection】American cars produced after 1996 are equipped with EVAP service ports; in most American cars, the EVAP service port is usually located in the engine bay, but the EVAP service port of some special models may be located elsewhere. Open the plastic cover of the EVAP service port, remove the check valve by turning it clockwise with a wrench, install the adapter for the EVAP service port, and channel smoke from the port into the EVAP leak detection system. 【Extended Testing Range】The smoke leak detector can perform smoke tests on multiple systems such as EVAP systems, intake systems, cooling/EGR/exhaust systems, crankcase systems, engine airtightness, vacuum leaks, and low-pressure turbo leaks. Applicable to cars, motorcycles, snowmobiles, off-road vehicles, ATVs, light commercial vehicles, and speedboats.
