Auto Smoke Machine

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;

The fuel tank system circulates when improper installation causes gaps in the fuel tank and pipeline.

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



operation steps

Flowmeter, Oil Level Meter & Pressure Gauge

The smoke tester automotive equipped with a pressure gauge, oil level meter, and adjustable flow meter helps easily control air pressure because the air pressure of each pipe in the car is different. If the air pressure is too high, the line will be damaged, and if the air pressure is too low, the leak will not be detected.

Therefore, the flow meter is essential to protect your detection system more effectively. All data are precise at a glance, which helps you better control the smoke effect and makes testing safer.

Smart Protection:

The car smoke machine has a smart protector to make it safe. Suppose the system detects that the amount of e-liquid in the instrument is insufficient or the continuous working time is too long; the system is overheated. In that case, the overheat protection indicator ALARM light will light up, and the smoke will stop outputting.

Ensure operator and machine safety until the temperature drops to the normal range and the instrument resumes work.

How to do leakage test?

1. Pour 20ml of baby oil or mineral oil into the car smoke detector

2. Use the hook to hang the smoke leak detector machine on the car

3. Disconnect the pipe that needs to be connected detector

4. Connect the detector the DC 12V battery and the device starts working

5. The pipes will be filled with smoke, check for leaks

dual modo

Dual Mode:

Air Mode: Air mode can help you test whether there is a leak in the pipe by injecting air into the line and judging by the sound made when the air leaks.

Smoke Mode: Smoke mode helps you lacate the leak accurately through the visible smoke. The smoke can be produced within seconds, dramatically reducing diagnostic time.

Note: Only after the AIR MODE is activated the smoke mode may start to work.

wide application


1. If the smoke weakens during use, the product's oil is insufficient; please refill it quickly.

2. Pour out all the old smoke oil before adding new smoke oil.

3. if the smoke has water droplets, please replace it with a new smoke oil.

4. The total amount of smoke oil filling at one time does not exceed 40; the initial fill volume may increase, which is normal. Excessive refueling can result in insufficient internal heating and no or less smoke output.

5. 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.

6. When the hook is lifted, please pay attention to tightening the nut on it to prevent the theme and the body from rotating each other many times; the body will fall off and be damaged.

7. When using the machine, do not start the engine; check the cold car or turn off the engine after the car is warmed up and test again.

ALMOST Perfect...

If there was a a sight-hole to show how much oil is in the machine, it would be great. Or, a dipstick that shows the amount of oil. They should make one attached to the oil-fill cap (maybe I'll j-rig one). Having to pour out any oil prior to use is inefficient.

Helped find our leak

One of our vehicles had a vacuum leak and I didn’t want to pay someone to find it.
This little machine saved me money and helped my husband easily find our leak to fix it.
He said it’s easy to use I only wish it was smaller for storage.


I was glad all pieces were included and it works as intended!
