AUTOOL Automotive Smoke Machine Lead Detector DC 12V EVAP Vacuum Diagnostic Tester with Built-in Air Pump for Pipe System

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.

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.

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.

I don't write many reviews, because I am not always over the top on a product that isn't a name brand that I know of. I needed to do a smoke test on my EVAP system. A local shop was going to charge me $150 to do the test. So I figure what do I have to loose paying $87 to buy this smoke tester. Well to my surprise the tester worked great and I was really happy. The only thing I will say negative is that the Battery hook aspect is honestly pointless. make it a plug in system and that is more useful. People don't do these type test out on the road to where a 12V hook up is nice. But if the 12 Volt way is the key, then make the wires longer. I had to test the EVAP on a Jeep and it is in the rear of the vehicle and the wires on the 12V connection would not reach, so I have to do a daisy chain using a pair of jumper cables to bridge the gap, but the system worked great and I found the leak. I saved money and even if the machine never works again I got my money's worth. But I think it will last and I will use it down the road if needed. The 12V cord issue is the only reason this didn't get a 5 Star review.

Works really well. Unit uses fluid like baby oil to produce smoke. I've used it a few times already. Both to find leaks on the intake side and also the exhaust side. For the exhaust side, I really like the inflatable airbag you pressurize. Stick it in the tail pipe, pump it up until it inflates to the size of the tailpipe and there is no more air gapes between them, then pump the exhaust full of smoke to find your exhaust leak. Does what it's supposed to do. Don't know if it would last in a shop where it would get used constantly but great cost effective alternative for DIY's.

Working great. I'm a retired auto tech and do minimal repairs since retirement and this has already helped me find pertinent vacuum leaks on 4 vehicles. Very good price for the quality, Very satisfied!👍
