[Multifunction] Our automotive smoke machine can perform various tests such as the EVAP system test, car sealing test, fuel tank system test, exhaust system test, intake system test, and various pipe fittings tests, etc. It Could be used on all cars, motorcycles, snowmobiles, ATVs, light trucks, boats, etc.

[Working Principle] The automotive leak detector tool will change special oil(baby oil or mineral oil) into smoke, then blow smoke into a sealed pipe system, you will find leak points in the pipe via the smoke. Please repair the part where leakage exists.

[Easy to Use] The automotive smoke tester with a hook allows you to hang it on your hood latch. Just add 20ml of baby oil or mineral oil, then connect the detector to the DC12V battery, it can output thick smoke within the 20s after turning on, and thick smoke output detects even the most minor leaks.

[Smart Protection] This smoke tester has overheat & freeze protection, the maximum temperature limit is 90°C, ture on antifreeze protection at a low temperature of -20°C. If it exceeds the working limit, such as over 90 ℃, it will automatically turn off the power to secure the safety of both the operator and the device.

[Lightweight and Portable] Most car smoke machines are bulky and heavy, which is not conducive to the transportation and storage of the equipment, and is only suitable for repair shops. Solary automotive smoke tester weighs only 3kg, to be small and light, not only for easy storage but also for ease of use. It is an indispensable tool for all car owners.


When your car has poor airtightness, it is unable to keep warm, dusty, not soundproof, and not waterproof;

when the air intake system leaks and causes insufficient air intake of the car engine;

when improper installation causes gaps in the fuel tank and pipeline, the fuel tank system spreads.

Don't worry, and our car smoke leak detector will help you find and solve problems quickly!

Overheating protection


  • After long-term use, the smoke oil will oxidize and deteriorate, and at the same time, it will affect the working state and life of the relevant parts of the instrument. Therefore, please replace the smoke oil in time.
  • Before adding new smoke oil, pour out all the old smoke oil.
  • When using, if the smoke has water droplets, please replace it with a new smoke oil.


Smart Protection

The car smoke machine is equipped with an overheat protection device. When the temperature is overheated, or the amount of e-liquid in the device is insufficient, the alarm (ALARM) indicator will light up, and the smoke will stop outputting;

The device will resume work when the temperature drops to the normal range. The cycle is about 5 minutes, so you don't have to worry about it.

Built-in Air Pump

You don’t need to connect an external air pump, so it does not rely on another air machine, ready for diagnosis and maintenance at any time! Perfect for Mobile Automotive Repair!

Wide application

Full System Diagnostics, Don't Miss Any Leaks.

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.

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 Tset: A leak in the intake system will result in inadequate car engine intake, leading to low engine performance.

Exhaust System Test: Uncleaned harmful gases escaping into the atmosphere or increasing the noise of the vehicle are the main disadvantages when leaks occur in the exhaust.

Car Sealing Test: Poor sealing of the car can lead to many inconveniences, such as it is not warm and dusty, not soundproof, not waterproof, etc.

Turbo Test: Coolant leakage would cause the engine to report high water temperature.

Various Pipe Fittings Test: Smoke testing of brake hoses, power steering hoses, cooling system hoses, turbocharger hoses, fuel hoses, intake and exhaust system hoses, etc.

It just needs more

This is lightweight for something made from an automotive paint sprayer but needs a flow Gauge. But I do like the low pressure it uses, especially for Evaps.
