Solary Automotive Smoke Machine Leak Detector - 12V DC EVAP Vacuum Diagnostic Tester for Pipe System

If you have anything that could leak, this is a must-have tool. It’s very straightforward to use. I just followed the directions for adding baby oil/mineral oil, and it was ready to go. There isn’t any adjustability since it’s just a simple on/off switch, but I actually like that it’s self-contained with its own pump. Since it runs off a car battery, it’s really portable and you can use it just about anywhere. It’s impressively quick, taking less than 30 seconds to start producing smoke. The silicone tubing and attachments that come with it are nice quality and cover most jobs, though I think including one more larger-sized cone would have been a nice touch. It’s not terribly loud while it's running. For a simple, reliable leak detector, this is hard to beat.

The Solary Automotive Smoke Machine Leak Tester is a solid tool for diagnosing EVAP system leaks, vacuum leaks, intake leaks, and more. It produces a steady smoke output to help identify leaks quickly and accurately. However, one thing to note is that it does not come with smoke fluid, meaning you’ll need to buy a solution separately before using it. Performance & Features ✔️ Efficient Smoke Output – Produces consistent smoke for easy leak detection ✔️ Versatile Use – Works on EVAP, turbo, intake, exhaust, and vacuum systems ✔️ Durable Build – Compact and well-constructed for shop or home use ✔️ Easy Operation – Simple hook-up to a 12V battery and ready to go Smoke Solution Requirement Since the machine doesn’t include a smoke solution, you’ll need to purchase mineral oil or baby oil separately. This is a minor inconvenience, but it would be more convenient if a small starter bottle was included. Final Thoughts The Solary Smoke Machine is a great tool for professionals and DIY mechanics. It delivers accurate and reliable results, but keep in mind that you’ll need to get smoke fluid before use. Despite this, it’s an excellent value for diagnosing leaks efficiently. Rating: ⭐⭐⭐⭐☆ (4.5/5) Pros: Strong smoke output, easy to use, versatile applications Cons: No included smoke solution, requires separate purchase

I picked up this 12V DC automotive smoke machine mainly to track down a stubborn EVAP leak on my '99 junkyard TJ, and it ended up being one of those tools you wonder how you worked without. Setup was straightforward—hook it to a 12V power source, add the smoke fluid, and you’re ready to go. It produces a steady, visible stream of smoke that makes even tiny leaks easy to spot around hoses, fittings, and gaskets. I’ve used it on EVAP systems, intake lines, and vacuum hoses, and it’s saved a ton of guesswork compared to spraying soapy water or chasing random trouble codes. What I really like is how practical it is for both DIYers and more serious garage work. It heats up quickly, feels solidly built, and doesn’t overcomplicate things with unnecessary features. If you’re tired of replacing parts hoping the check engine light stays off, this tester helps you diagnose the actual problem before spending more money. Overall, it’s a reliable, time-saving diagnostic tool that pays for itself fast if you work on your own vehicles or help friends and family with repairs.

This thing works great for detecting evap leaks in older vehicles with failing vacuum hoses. Puts out a lot of thick smoke that makes finding leaking hoses easy. Pinhole leaks are still a little tough to see, but as long as you aren't using this outside where the wind will blow it away you should still be able to find it. The ability to hang it from the hood and clip it directly to the battery is a very nice touch and makes it easy to keep it out of the way during use. The included adapters allowed it to fit everything from my intake pipe out of the air filter box to the hoses going to the evap canister at the rear of the vehicle. Holds a good amount of fluid as well; I was able to go for about an hour of total run time during my 8 hours of finding and fixing leaks on an old turbo car without having to refill. Overall, I believe the unit paid for itself in just that one job over taking it to a shop and having them find all of the leaks and repair them.

I have used this Solary smoke machine over twenty times across a range of EVAP and vacuum leak diagnostics and it has been reliable every single time. Powered off a standard 12V DC connection, it fires up quickly and produces a consistent smoke output that makes tracking down even small leaks straightforward. The smoke is visible enough in good lighting and excellent in low light conditions, which is what you need when tracing a hairline crack or a loose fitting. The size is compact enough to store on a shelf or in a rolling cart without taking up much real estate. Build quality looks and feels like a purpose-built shop tool rather than a cheap import knockoff. The connections are clear and the unit is easy to identify what attaches where without needing to dig through a manual. Setup the first time took only a few minutes and subsequent uses are plug-and-go. Ease of use is one of the stronger points here. Hook up the hose, connect your power, introduce smoke into the system, and watch for leaks. No complex menus or fiddly adjustments. Noise level during operation is low enough that you can carry on a normal conversation in the shop without raising your voice. One real limitation to be aware of: there is no built-in pressure regulation. If you are connected to a sensitive system and are not monitoring carefully, it is possible to over-pressurize. This is not a deal-breaker but it does mean you need to stay attentive while the unit is running and use an inline regulator if your application requires it. Storage is straightforward since the hose and adapters tuck away without any drama. For the price point this machine earns its place in the shop. After twenty-plus uses without a single failure, I am comfortable recommending it to anyone doing regular EVAP or vacuum diagnostics. Just respect the pressure limitation and you will have a capable and dependable tool.

Bra pris och fungerar som den ska, har haft nytta av den flera gånger. :)

Muy útil tiene su compresor incluido y arroja humo a presión suficiente para revisar varios tipos de fugas desde vacíos en admisión y escape así como fugas de aceite y sistema de enfriamiento

Très utile et pratique. Fonctionne sur batterie 12V. Elle m'a permis de trouver des fuites a l'admission de mon véhicule et des fuites sur un circuit d'huile. Je recommande sans hésiter. Fonctionne avec de l'huile pour bébé. 👍

Al inizio ero titubante perché avevo letto qualche recensione negativa ma alla fine mi sono deciso a prenderlo. Ottimo attrezzo valido per il suo prezzo da il suo dovere alla grande unica pecca mancanza di tappino per chiusura tubi
