Why is it recommended to detect leaks in automotive EVAP systems?

With the implementation of the international emission standards represented by CARB LEV III and EURO 6 and the requirements of on-board diagnostic systems, nowadays vehicles need to have on-board diagnostic function for small leakage (0.5mm or 1mm aperture) emissions of EVAP system. The frequency of EVAP system leak alarms increases compared to vehicles without on-board diagnostic requirements. Therefore, the owner goes to the maintenance station to check the EVAP system. The demand for leak inspection and leak discovery will also rise accordingly. For special maintenance site of the vehicle enterprise, it is necessary to equip professional EVAP leak inspection and special tools for locating leak points. The AUTOOL SDT 101 Automotive EVAP leak detector is a powerful repair tool for EVAP system detection.

Why do customers need AUTOOL SDT101 Automotive Smoke Leak Machine?

AUTOOL SDT101 model is easy to operate. It can help you quickly and accurately find if a failure is caused by a plumbing leak, even the smallest leaks can be detected. Through the precise pressure regulation of the external air supply, SDT 101 can output the standard test pressure of 32mbar required by the automotive EVAP system. Moreover, it can output smoke within a few seconds, greatly improving the diagnostic efficiency. SDT 101 can be widely can be widelyused in all SUVs, MPVs, racing cars and household pickups with EVAP system, as well as trucks, engineering vehicles, tractors etc. It can accurately find vehicle problems and diagnose faults with automatic diagnostic tools.

Complete system diagnostics without missing any leaks.

Crankcase System Test: Excessive pressure or corrosion of the crankcase is the main reason for damaging the seal of the crankcase and cause oil leakage.

Intake System Test: Leakage in the air intake system will lead to insufficient intake of the car engine, resultingin scant engine power.

Car Sealing Test: Poor airtightness of the car may lead to a lot of inconvenience like inability to keep warm dusty, not soundproof, not waterproof and so on.

Fuel Tank System Test: When the tank and pipeline are improperly installed or the tank cap is not sealed in place and there is a gap, the tank system may cause leakage.

Turbo Test: The leakage of coolant would cause the engine to report high water temperature. All kinds of Pipe Fittings Test: Smoke testing of brake hoses, power steering hoses, cooling system hoses, air conditioning system hoses, turbocharger hoses, fuel hoses, intake and exhaust system hoses, etc.

EVAP System Test: Leakage of the fuel evaporation system will cause fuel vapor to leak into the atmosphere, causing waste and pollution or engine idling instability.

Exhaust System Test: When exhaust gas leaks, harmful gases are not purified into the atmosphere or increase vehicle noise is the main disadvantage.

Small Size Design

Most smoke leak detectors are bulky and heavy, which are not convenient for transportation and storage, so repair shops are their main users. To solve this issue, AUTOOL designed this 4-pound machine to be small and light, not only for storage but also for ease of use. It is an indispensable tool for any car owner.

Fast Smoke Output

AUTOOL SDT101 uses an external air supply and has a superior wick and heating elements. It can produce smoke immediately by heating USP mineral oil or baby oil. A 4ft exhaust pipe helps to make the perfect connection.

Overheating and Antifreeze Protection

Our smoke leak detector is equipped with the latest intelligent protection devices. When the temperature exceeds 75 degrees Celsius, the protection device will intelligently start and shut down the power supply, protecting the operator and equipment. Our device is also suitable for low temperature operation.

Wide Range of Applications

AUTOOL SDT101 Car Smoke Leak Detector is a professional automotive pipeline leak detect tool and without air pump. It will help us position cars motorcycles leakage on pipe system quickly and exactly, is used to detect leaks in piping systems in automobiles, motorcycles, snowmobiles, ATVs, ATVs, light trucks and speed boats, suitable for all models (only for 12v DC). For non-professionals, many users may worry about its utility value because they do not use it very often and maybe only use it once for a long time, so is it worth spending so much money? Yes, you can also use it to give to your friends or neighbors, or even rent it out for extra income.

How to do leak detection?

1.Fill 10ml-20ml test oil into the smoke leak detector. Disconnecting the car pipelines that needs to be connected to the smoke leak detector.

2.Connect the adapted quick interface to the automobile pipeline to be tested. Connecting an external air supply to the air inlet of the smoke leak detector.

3. Connect the smoke leak detector to the DC12V battery, and the device starts to work. Turning on the smoke switch, and smoke will appear after about 5 seconds.

4. Connected to the detected vehicle pipeline, it will soon be filled with smoke, which is convenient for locating the leak point.

【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】Connect shop air supply, connect 12V vehicle power, Press the AUTOOL SDT101 smoke control switch, the indicator lights on, wait for about 10 seconds, insert the cone head on the smoke outlet pipe into the air inlet cone adapter when the smoke becomes thick.Wait for about 1 to 2 minutes, you can use a flashlight with strong light to help find the leaks in the pipeline and then AUTOOL SDT101 smoke machine automotive will diagnose the leakage status.
【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.
【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.
【Advanced and Safe】The AUTOOL SDT101 evap smoke machine with thick smoke output detects even the smallest leaks. It is safe and reliable as there is no need to start the vehicle during use. And the smoke output is healthy and harmless. Moreover, when this smoke leak detector can be smart power off, the power will be automatically shut off when it exceeds the 75 ℃ housing limit.
