🗣️You may want to know.
Power Supply: The smoke test machine must be connected to a 12V battery to operate.
Test oil: Kindly note that, due to logistics restrictions, we are unable to include testing oil in the package. You can easily buy liquid paraffin or baby oil locally for use as the testing fluid.
First-Time Use: Each time you use the smoke tester car, please fill it with 10–15ml of testing oil. Do not exceed this range, as there will be no space left for smoke generation.
Testing Oil Refill Tips: Only refill when the smoke becomes thin. Do not add more than 15ml at a time. Always drain the remaining test oil before adding fresh test oil.
Safety Precautions
- Do not operate the smoke leak detector continuously for more than 8 minutes; allow it to rest between uses.
- The smoke test machine features an intelligent protection system that automatically shuts off if the internal temperature exceeds 75°C. Please wait for it to cool down before restarting.
- The metal round section of the smoke tester car can become hot during operation—avoid direct contact to prevent burns.

AUTOOL SDT206 Smoke Machine For Vacuum Leaks Features
- Built-in Air Pump: The AUTOOL SDT206 smoke test machine comes with two built-in high-quality air pumps, eliminating the need for an external air source.
- Air Mode and Smoke Mode: Built-in air pump and smoke generator, so it does not rely on an additional air machine, perfect for Mobile Automotive Repair! The smoke can be produced within 10 seconds, dramatically reducing diagnostic time. Smoke output value: 6L/min.
- External Pressure Gauge: You can observe the barometer to more accurately determine whether the car pipeline is leaking. If the barometer index keeps increasing, there is no problem with your car’s pipeline. If the barometer index keeps decreasing, it signals that your car’s pipeline has leaks requiring repair, and you can perform a barometer test to verify it. Leakage is faster and more accurate.
- Overheat and Anti-freeze Protection: The AUTOOL SDT206 vacuum leak tester uses the latest intelligent protection devices. When the temperature exceeds 75℃, the protection device activates and shuts off the power supply to protect both the operator and the equipment. It resists high temperatures and performs well in low temperatures.
- Wide Range of Applications: The AUTOOL SDT206 vacuum leak tester is suitable for detecting leaks in automobiles, motorcycles, snowmobiles, ATVs, ATVs, light trucks, and speed boats, suitable for all models(only for 12v DC).
- Fast Smoke Output: Smoke output is within ten seconds, greatly improving your efficiency in the test.
- Compact and Portable Design: Most of the smoke machine for vacuum leaks on the market are large and not easy to transport and store, AUTOOL designed this smoke leak detector to help you solve this problem, not only is it small in size and light in weight, but also easy to carry. The handle design, cone adapter, and airbag adapter easily adapt to most air inlets, making them indispensable tools for you.
- 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, it damages the pipe, and if the air pressure is too low, it fails to detect the leak. Therefore, the flow meter is very important to protect your detection system more effectively. Make testing safer.
- 3-Year Warranty: For damage caused by non-human factors, we promise to reissue parts free of charge within 3 years.
How To Use The AUTOOL SDT206 Automotive Vacuum Leak Tester?
- 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 DC 12V 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.
Packing List
FQA
If you can’t find a professional test oil, you can buy liquid paraffin or baby oil at your local store as test oil.
It’s suggested to add 10-20ml testing oil for the first trial. Please drain some testing oil out if you add too much accidentally. You can reuse the extra next time.
First, pressurize the air-conditioning pipeline, then spray smoke and observe if the airflow blows it. If there is, it means that the location is a leak point, you can repair later.
