Product Description:
  • Why Need Smoke Leak Detector ?:

    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.


  • SDT50 Automotive Smoke Machine Key Features:

    【No Air Pump】: AUTOOL SDT50 EVAP smoke machine has a built-in air pump and does not rely on other external air sources. You do not need to buy additional air pumps. Only one machine is needed for normal operation, saving you more time and money.

    【Quickly Detect】: Connect the smoke leak detector with DC12V battery, press the AUTOOL SDT50 smoke detector switch to output a large amount of smoke within 30 seconds, so as to find the leak point faster.

    【Wide Testing Range】: AUTOOL SDT50 smoke leak detector for detecting the leakage of pipe systems on cars, motorcycles, snowmobiles, off-road vehicles, ATVs, light trucks and speedboats boats.Works on all car makes and models(only for 12v DC).

    【Advanced and Safe】: The AUTOOL SDT50 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°C or below -20℃ housing limit.

    【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 3-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.


  • Car Smoke Machine Full System Diagnostics:

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

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

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

    4. Fuel Tank System Test: When there are gaps in the fuel tank and piping caused by improper installation or insufficient sealing of the fuel tank cap, it can cause leaks in the fuel tank system.

    5. Turbo Test: The leakage of coolant would cause the engine to report high water temperature.

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

    7. Exhaust System Test: Unpurified harmful gases to be discharged into the atmosphere or increase vehicle noise is the main disadvantage when leaks happened in the exhaust.

    8. Various 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.


  • How To Perform A Leak Test?

    Step 1: Fill 10-15ml baby oil into the detector for the first time. Open the engine cover, and hang the detector in the cover.

    Step 2: Disconnect the pipe that needs to be connected to the detector.

    Step 3: Connect the detector with the DC12V battery, turn on the power switch, and the detector starts to work.

    Step 4: In about 30 seconds, the pipe will be filled with smoke. Check the leak points. Please use a headlamp if necessary.
