Smoke Machine Automotive Leak Detector,Evap Vacuum Smoke Diagnostic Tester,Pipeline Fuel Leakage Detector Compatible with 12V 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
【No Air Pump】1. The AUTOOL SDT103 smoke leak detector doesn't come with an internal air pump, so you'll need to connect it to an external workshop air source and a 12V vehicle power supply to bring in the workshop air.2. Turn the flow control dial of the AUTOOL SDT103 smoke leak detector counterclockwise to open the airflow, and then switch on the power at the back of the device. This will start the AUTOOL SDT103 machine, generating smoke. (When adding smoke oil to the AUTOOL SDT103 smoke leak detector, make sure not to exceed 20 ml, and please use baby oil or paraffin oila).
【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 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.

Smoke Machine Automotive with Built-in Air Compressor, Professional Smoke Leak Detector for Car, Diagnostic Leak Tester Tools for EVAP, Vacuum, Fuel and More Leak Testing

【Comprehensively Detecting Various Types of Leaks】This smoke machine leak detector can produce columnar smoke at the point of leakage, so as to locate the leakage point in the compartment, repairing it in time and improving driving safety. Great for detecting leaks from throttle shafts, engine blocks, turbo test systems, crankcase systems, air intake systems, exhaust systems, fuel tank systems, EVAP systems, EGR systems, cooling systems, and various piping in a wide range of vehicles (including older models).
【Safe Car Smoke Tester】This vacuum leak smoke tester automotive is made of thick metal, compact and durable. It has a smart protection device that automatically cuts off the power if the working temperature exceeds the limit value to ensure the safety of the operator and the smoke machine. The device uses baby oil to produce harmless smoke and is perfect for leak detection in the ductwork of all DC12V vehicle types such as cars, motorcycles, snowmobiles, ATVs, light trucks and speedboats.
【Complete Leak Detection Adapters & Extra Duct Caps】Our multi-functional vehicle smoke machine includes cone adapters, smoke delivery hoses, air intake bladders that work seamlessly with a wide variety of lines and hoses, making it ideal for checking vacuum, fuel, engine, air intake systems, and more. The additional 7 different sized pipe caps feature a tapered design for a tight seal at the appropriate pipe and are made of high quality automotive grade plastic for durability.
【Built-in Air Pump & Fast Smoke Out】This automotive smoke machine has a built-in air pump, no need for additional air connection and external air pump maintenance cost, high efficiency, convenient and money-saving. The built-in air pump's compressor generates 19 to 23 psi of air pressure to easily introduce smoke into the automotive system under test, which can produce a large amount of smoke within 10 seconds, allowing you to quickly and accurately locate leaks.
【Accurate Leak Detection and Pressure Decay Test】Built-in adjustable flow meter and pressure gauge allows you to quickly and accurately detect even the smallest leaks, ensuring an accurate diagnosis every time. It also supports pressure decay testing, which identifies tiny leaks by applying a specific pressure and monitoring the pressure gauge, especially for hard-to-find vacuum leaks.
