With the implementation of international emission standards represented by CARB LEV III and EURO 6 and the requirement of an on-board diagnostic system, it is necessary for vehicles to have an on-board diagnostic function for small leakage (referring to 0.5mm or 1mm aperture) emission of EVAP system. Compared to cars without on-board diagnostic requirements, the frequency of EVAP system leak alarms will increase, so there will be a corresponding increase in demand for owners to enter service stations for EVAP system leak detection. For the special service stations of vehicle companies, a professional EVAP leak inspection and special tools or equipment for locating leak points are highly recommended, and our AUTOOL SDT 103 Automotive EVAP Leak Detector is a perfect tool for EVAP system inspection and repair. Why do customers need AUTOOL SDT103 automotive smoke machine? The AUTOOL SDT103 Automotive Smoke Leak Detector can assist service technicians in leak detection testing. The AUTOOL SDT103 Automotive Smoke Leak Detector can assist service technicians in leak detection testing. Leak detection is the most basic but absolutely essential test in the automotive repair process. The SDT 103 Automotive Smoke Leak Detector is capable of outputting a constant standard test pressure of 32 mbar required by automotive EVAP systems through precise pressure regulation of the external air source, which can output smoke within seconds and can find leak holes as small as 0.5mm. Crankcase System Test: Excessive pressure or corrosion of the crankcase is the main reason to damage the seal of the crankcase and cause oil leakage. Intake System Test: Leakage in the air intake system will lead to insufficient intake of the car engine, which will result in scant engine power. Car Sealing Test: Poor airtightness of the car may lead to a lot of inconvenience like inability to keep warm dusty, not soundproof, and not waterproof , etc. Fuel Tank System Test: When there are gaps in the fuel tank and piping caused by improper installation or insufficient sealing of the fuel tank cap, it can cause leaks in the fuel tank system. Turbo Test: The leakage of coolant would cause the engine to report high water temperature.Various Pipe Fittings Test: Smoke testing of brake hoses, power steering hoses, cooling system hoses, air conditioning system hoses, turbocharger hoses, fuel hoses, intake and exhaust system hoses, etc. EVAP System Test: Leakage of the fuel evaporation system will cause fuel vapor to leak into the atmosphere, causing waste and pollution or unstable engine idling. Exhaust System Test: Unpurified harmful gases to be discharged into the atmosphere or increase vehicle noise is the main disadvantage when leaks happened in the exhaust. ## 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. ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B0BGB41DLK | | Best Sellers Rank | #16,580 in Automotive (See Top 100 in Automotive) #10 in Fuel Leak Detectors | | Brand | AUTOOL | | Customer Reviews | 4.4 4.4 out of 5 stars (1,042) 4.4 out of 5 stars | | Date First Available | September 24, 2022 | | Item Model Number | SDT103 | | Item Weight | 4.69 pounds | | Manufacturer | AUTOOL | | Manufacturer Part Number | SDT103 | | Model | Automotive Smoke Machine | | Product Dimensions | 8.66 x 12.2 x 12.2 inches | ## Product Details - **Brand:** AUTOOL - **Item Weight:** 2.13 Kilograms - **Alarm:** Audible - **Operating Humidity:** 95 percent - **Number of Items:** 1 - **Manufacturer:** AUTOOL ## Images ![Smoke Machine Automotive Leak Detector,0-0.46PSI Evap Vacuum Smoke Diagnostic Tester,Pipeline Fuel Leakage Detector Compatible with 12V Vehicles - Image 1](https://m.media-amazon.com/images/I/61YpFef6TvL.jpg) ## Available Options This product comes in different **Model** options. ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ I recommend it *by on Reviewed in the United States March 1, 2025* 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 as advertised *by on Reviewed in the United States May 14, 2024* This review is for the Autool Model SDT103 Smoke Leak Detector. I did a lot of research before buying this product. I opted for this unit, which has no internal compressor, because it has less parts to break and I have my own compressor. (It uses almost no air; just a trickle.) I also liked that it has flow control and a flow indicator. Please be aware, I've only used this unit one time, so I can't comment on its long term reliability.I read the instructions before using it, and the instructions are pretty well written, and describe how to operate it without a whole lot of difficult-to-understand broken English. The unit is pretty simple, so its operation is straightforward.I bought a little 3 ounce bottle of baby oil from CVS for a couple bucks. I put 20mL into the unit before turning it on (the instruction booklet said 10mL, but there were two stickers on the actual unit that said 20mL, so I used 20mL). I let the air flow through it for a minute or two before I turned on the smoke switch. The smoke took about 30 seconds to start coming out, and maybe 2 minutes before it got really thick. I used this for diagnosing a vacuum leak in the intake of my Ford Ranger. The smoke was nice and thick and was easily seen (see picture).The packaging is very good on this product. All accessories are in separate ziplock bags, very organized, very neat. All the accessories (hoses, wires, oil bottle, etc) seem to be very high quality. I was expecting a one-time use throw-away item, but this seems to be well made and has quality accessories.I'm surprised to hear that some people write reviews complaining about the smell of the unit after using it. It burns oil to generates smoke. The smoke smells like burning oil. Why would someone expect this unit to not smell like burned oil?This product saved me a lot of money going to a mechanic to diagnose the problem in my car. I'm also going to use it in the future to find exhaust leaks, and leaks in other sealed systems in my cars. I'm not a mechanic, but I do almost all the work on my cars and I think this will come in handy in the future.I recommend it. ### ⭐⭐⭐⭐⭐ Works great, no complaints. *by on Reviewed in the United States August 5, 2026* I had low hopes for this due to the price compared to other "professional" units but it is surprisingly good! I've used it several times now in the process of restoring/ troubleshooting a '94 Land Rover engine and exhaust and it works perfectly. I'm glad I took a gamble on this one. I bought some UV reactive smoke juice with it, and while it smoked fine, it wasn't actually UV reactive, but it smells so bad it's easy to find the leaks! ## Frequently Bought Together - Smoke Machine Automotive Leak Detector,Evap Vacuum Smoke Diagnostic Tester,Pipeline Fuel Leakage Detector Compatible with 12V Vehicles - Smoke Fluid Solution for Automotive Smoke Machine Testing - Made in USA - 8oz Liquid Smoke Refill Designed for Automotive Testing - EVAP, Vacuum, Fuel, Intake, Exhaust, Turbo Systems & Super Chargers --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/475869511-smoke-machine-automotive-leak-detector-0-0-46psi-evap-vacuum](https://www.desertcart.sn/products/475869511-smoke-machine-automotive-leak-detector-0-0-46psi-evap-vacuum) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-09-12*
