AUTOOL Universal Car Smoke Leakage Detector EVAP Car Pipe System Leakage Locator 12V Automotive Smoke Machine for Car, Motorcycle, Truck

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.

Super useful and easy to operate. I should have bought one of these machines much sooner. Highly recommend for tracking down those hard to find vacuum leaks on your engine. Comes with an assortment of accessories for just about any application. Uses only a tiny amount of mineral oil, so one bottle will last you a long time. No smell or fumes from the smoke this unit produces. Safe to use indoors. Well built. Love the pressure scale and easy toggle switch. Not noisy either, runs quiet.

Big fan of this tool. I purchased this because it had all the Extra Bungs and attachments for intake system and EVAP systems. Additionally you can vary the pressure and amount of smoke coming out. Others are just a simple on/off. Worked perfectly as intended. Now I have a reasonable priced smoke tester for my occasional testings.

Works as expected. With smoke and as a leak detector. Great tool for finding vacuum leaks and leaking spots in engines, exhaust and fuel system

The media could not be loaded. This "smoke" generator is the best out of other 2 I had previously. One died and another one just sucked really bad. Poor design and quality. Everything was leaking and they just shoved a heating wire wrapped around a piece of cloth inside a paint can etc. it was bad and frustrating. This one is just freaking awesome!!!! It simply works with my car tire inflator!!!. Now don't get misled. I did convert it. Because my car inflator end had connection for the tire plug or whatever it called. I had everything for that. Now about the flow... Oh damn it is great flow of vapor it is so nice and visible!!! So much in the kit that comes with it I have no idea what for. And yeah I know on the picture I didn't need all that many adapters, I just had it like this in my later bag and I was lazy to redo them I know some are extra there . Anyway, great product! No leaks, works great out of 12V battery and it is fine with 21 psi of the car tire inflator!

I have been using this machine in a professional setting. Puts out plenty of smoke, and comes with more than enough adapters to get the job done. I have tested evap systems, intakes, and exhausts. Every time this machine performed as well as the higher end machines. My coworkers were jealous when they saw the price of this, and have all bought machines well over $1000. Buy it, and don't look back.

This is a fantastic little machine. I've already used it on two cars, and the flow gauge is accurate. Makes plenty of smoke. It does not come with Fluid, so make sure to pick some up. But - Great to have in the collection. Thanks!

For the back yard mechanic this is perfect. Plenty of smoke and tons of adapters. Produces smoke in seconds. Build quality is good. I don't have need for everyday use but I'm sure it's going to last years.
