Review: I recommend it - This is great! Easy to use! I used a small amount of mineral oil. It makes a very good amount of smoke, it's adjustable, I turned the dial about half way. It connects with clamps to your positive and negative battery cable so it's totally portable to use outside if you're not able to work on your car at home. If you're in an apartment or don't have 110 AC, this is great because it runs off 12 volts DC. If you needed you could connect it to a power bank but the car battery works well . I was using it for approximately 10 minutes and it did not drain my car's battery to a point where it would not start. There was plenty of cranking power after I thought. I'm not sure how many amps it pulls . As far as the Air supply, It does not have a built-in one. You need external Air supply but you do not need to have shop air compressor, I used a bicycle pump with some acrylic tubing, a tire valve stem, hose adapters and a quick coupler for an air compressor hose for the female end to connect to the smoke machine. The bicycle pump method worked perfectly. I could control the flow of of air by hand. Very easy and there is no risk of pumping in too much air during your testing. You do not want to have a high amount of air pumping into that machine and filling up your engine Chambers with the too much air could blow something. Only need about 5 psi. No worries with there the bicycle pump method and it was very cheap to rig up. This is a must have diagnostic tool for all mechanics. This has helped me find vacuum leaks with ease. I would have never found this leak I had, it was a massive leak of air my car has in the throttle body area. It's in a tight spot. This helped me to determine where the exact leak was coming from. The TB gasket turned out to be fine after 35 years, it was the gasket to the air tube that seals around the mouth, which was an easy fix. I also had a small leak around and after market CAI intake elbow joint. I confirmed the repairs with the smoke test and the car ran much better. I recommend this.
Review: Good for the Money. - Works great, lots of smoke. Beware the heated mineral/baby oil will stink up your garage for a long time. So bad I am unable to use this inside my garage. In storage the smell is still so bad, I have to store this outside. For the money I am satisfied. Still could not find the Evap leak on my 2005 Suburban, but not the fault of the machine. Think the leak may be on the top of the gas tank where I cannot see the evap lines. The pressure gage is a must. It is missing on other similar priced smoke machines. Tells you there is a leak if the ball does not fall to the bottom. To test, close off the smoke tube and it will go to the bottom.

## Features

- 【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】Note: AUTOOL SDT103 does not have an internal air pump. External air supply is required for use. Connect shop air supply, connect 12V vehicle power, introduce shop air to the AUTOOL SDT103 fuel leak tester, turn the Flow Dial anti-clockwise to open the air flow, switch on the power at the back of the unit, then AUTOOL SDT103 smoke machine automotive will start to generate smoke
- 【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 AUTOOL SDT103 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.

## Questions & Answers

**Q: what do i use as an air source?**
A: The air compressor can provide the air source.

**Q: Does it come with smoke fluid?**
A: Thank you for your attention to our AUTOOL smoke tester, very sorry, our smoke tester does not contain cigarette oil, because it belongs to flammable liquid, transportation is more complicated, so you need to buy it separately, causing you inconvenience, we are very sorry, if you have any questions about the goods, please feel free to contact us, we are always here for you.

**Q: What types of oil can be used? Mineral oil, baby oil, castor oils?  Does it come with any oil? How long will it blow smoke with the 10ml that you add?**
A: Does not come with oil.   There are several types of oil you can use based on what you are doing.  I would not normally try any of those choices.   For anything to do with a car you should go to a car parts place and get smoke machine oil.

**Q: What size Air source quick connection does it take**
A: 1/4 industrial fitting, not automotive. I wasn’t able to replace it with and automotive one but you can add some adapters to it so it connects to your hose with automotive coupler.

### ⭐⭐⭐⭐⭐ Nicely accessorized kit, paid for itself in one use!
*by M***T on August 4, 2024*

Great piece of kit. Paid for itself within 15 minutes of arriving on my doorstep (overnight - thanks Amazon!). Immediately helped me identify the cause of a mysterious air/fuel issue I’ve been fighting for weeks. Easy, cheap fix, but in a spot I never would have been able to get eyes on without a stream of smoke and an inspection mirror. Saved a lot of time and money swapping out engine sensors trying to identify the true cause of the issue. I chose this unit over other similar and dissimilar models particularly for the built in air regulator and the assortment of fittings. While cheaper units with the built-in mini air compressor are appealing, the compressors have a high failure rate and a very low airflow volume. This kit is as reliable as the compressor I connect it to. Plenty of smoke output, and the adjustable smoke output is helpful, as too much can actually obscure the source leak. Only slight complaint is I feel the manufacturer should have included a single use 20ml container of smoking fluid (mineral oil). I knew it didn't include any, and I already have butcher block mineral oil on hand, but the principle remains. Overall, an affordable, full featured and compact unit.
