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.
  • If the smoke has water droplets, please replace it with a new smoke oil.


Smart Protection

The car evap smoke machine leak tester 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.

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.

Christopher Barone
Give it plenty of time to warm up

I liked that it made plenty of smoke once warmed up I didn’t like the volume of smoke fluid it held

Found my evaporative leak!

The Solary SD303 was a budget price but still worked to find my leak, would recommend to others.

Perfect for the job

It worked as I expected and easy to use.

Works good

Used it a few times. Works good

It works fine

My friend is a mechanic and owns a shop, he didn't have any smoke machine because of the cost in the past, he didn't even realize they have all of these cheap Chinese machines, but my 2001 Toyota Camry came up with a evap code with check engine light, so i bought this for him and he used it to diagnose the problem and repaired it it straight away so it works fine. My friend owns Joe's Auto Repair in Manteca California and is a great guy and good automotive technician
