Why do you need a VXSCAN V4 auto EVAP smoke machine leak letector?
Exhaust leaks can be bad for your health and can cause backfiring in carbureted cars. You can use the VXSCAN V4 automotive smoke machine to help find exhaust leaks, without running the engine and gassing yourself.
You can smoke test EVAP systems, vacuum leaks, low-pressure turbo leaks, intake manifolds, cooling / EGR / exhaust systems, decay system, worn rubber, gaskets, seals, connectors, and more.
In modern cars, many check engine codes are set off by an air/vacuum leak. Quickly dialing in the problem will save you time and money in a shop and help a home mechanic find the problem instead of just changing parts.
Diagnose DPF Frame Faults: Recognize deficiencies before they trigger extreme constrained DPF recoveries or the motor going into de-evaluated activity. Find unsettled upstream holes (exhaust roars, V-clips, ventilation system ribs, broken tubing, compacted air charge spills) to stay away from the untimely stopping of the DPF.
Decrease Analytic Time: As well as discovering releases quicker and all the more proficiently, the automotive smoke machine can significantly decrease analytic time and assist with disposing of rebounds. It can rapidly find spills in super/support, charge air cooler, exhaust framework, wind and water, lodge, consumption framework, seals, gasket, hoses, fittings, and the sky is the limit from there.
Holes Speedily Cycle: With protection upkeep utilizing a V4 smoke machine automotive, finding holes can be a speedy cycle rather than a significant fix issue in the shop or a breakdown out and about. Utilizing a hole analyzer during standard upkeep can forestall issues and consider fixes before spills become a significant issue that cause lost time and cash for an armada.
Adjustable Output Pressure
- For the fuel evaporation system (EVAP), the test pressure value is 0.5psi, for other systems the test value is 7-14psi, for special systems (turbo, etc.) the test pressure is greater than 14psi, so 0.4-17psi is full coverage.
- Adjustment the output pressure method: Turn the top knob left to decrease, and turn right to increase. It is necessary to block the smoke outlet to confirm the actual value of the output pressure, which is the highest test pressure set.
Adjustable Air Flow Meter
- Provide a quick visual indication of the amount of air/smoke passing through the system being tested.
- Check the Digital Pressure Gauge & Flow Meter reading for leak status, V4 evap smoke machine can help you find and fix leak problems quickly!
- Output Flow: 1-7 L/min
- Air Flowmeter with adjustable button, easy to observe and operate
External Digital Pressure Gauge
- Four kinds of units (psi, bar, kpa, kg/cm2) can be switched to adapt to different markets. There is a hole under the digital display window, which can be switched by poking it with an iron wire with a diameter of no more than 2mm. Short press to switch units.
- Press and hold to perform pressure calibration (return to zero). When performing this step, no load can be connected (to ensure smooth output and the system does not hold pressure).
EVAP Testing Function
- 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.
Overheat & Anti-frost Protection
- This smoke detector is equipped with the latest intelligent protection device.
- When the temperature of the device exceeds 70 degrees Celsius, the power protection device will be intelligently activated to turn it off, to ensure the safety of the operator and the device. The device is also suitable for low temperature operation.
Wide Range of Applications
- VXSCAN V4 car smoke detector used to detect leakage of pipe systems on automobiles, motorcycles, snowmobiles, ATVs, light trucks, and speedboats.
- The smoke machine automotive is suitable for all makes and models of cars.

The machine works great. Provides a good strong and steady smoke stream in a very short amount of time.The digital readout is very clear, accurate and can be switched to 4 different scales. It has an easily adjusted flow meter AND the feature that I liked best, is the built in pressure regulator that can be adjusted to precisely set the pressure anywhere from 0 to 15 PSI. Many of the other machines I looked at did not have this feature and were much higher priced that this unit. No need to purchase overpriced oil, this unit uses Johnson’s Baby Oil and it has a one year warranty. Highly recommend!

Did some work on my 03 XK8 and decided to run a diagnostic on my OBD2 system. Fuel trims were uncomfortably high positive suggesting engine was running lean. Corrected a number of small leaks located with brake fluid but total trims remained higher than expected. Decided to try a smoke machine and purchased this based on overall value and ability to test the evap. The smoke machine hook up was easy and the machine was smoking in seconds. A few turns of the adjustment knob and I was at 1/2 psi and found my upper plenum seals leaking within 1-2 minutes. Very easy to use and plenty of hose to place the smoke machine away from the vehicle. I was originally sceptical of the 5 minute cycles but found the leaks so quickly the cycles didn't matter at all. Should have bought this years ago.

Came with great attachments, quality is FAR better than I expected. Has everything that even the Harbor Fright machine at $549 comes with, except the pretty black case...if I REALLY want a case, I can buy one for ALOT less than the $450 difference. Even if I were still turning wrenches for a living, and would consider this VS a Snap-on or MAC machine...I could buy ten of these before I have even started to pay off the tool truck machine.Just fill it with mineral or baby oil, hook it up, adjust your flow rate, and find your leak. That simple. Find your fitting to seal onto your intake, exhaust, whatever you need to test...I recommend doing this in a garage, or on a less windy day...but your leaks will become obvious pretty quick...a simple laser pointer makes it easier, just start pointing it around, up under the dash if you are working on the AC system, the laser will get very visible in the smoke.

Soon as the smoke circulated the air intake system I instantly found the leak. So , so, so easy.For DIY great. I would recommend for DIY at home. $133.00 dollars. Dealer troubleshooting is $180.00 an hour labor, it paid for itself plus i made money. Why? Because the Dealership did not hook up a vacuum hose when they worked on my vehicle last week. Yes I could of took it back. They probably fix free, but they would keep my truck for a day or two. I saved my time. Update : used this on two different vehicles. Such a time saver. Smoke is the way to go for troubleshooting vacuum leaks.

I have had this smoker since December but never had a chance to use it until yesterday. The first time I used it, it worked fine until I finished the first job then the pump quit working. The manual says it has a one year warranty but the manufacturer is in China and says to contact the supplier but no information who the supplier is. Not real happy with this unit.I've changed my rating because I was able to contact the seller and was quickly given a full refund. I actually give the unit three stars due to the apparent lack of repair part availability. However, it seems to be well built and a fully capable machine, one of the lowest cost on the market and mostly good reviews so I did purchase another one, hoping it will hold up with time.I give the seller five stars and hope to do business with them in the future.

I drive a 20 year old truck with a v6 that had a bad idle, been chasing vacuum leaks one at a time for a long time. Finally I got this and smoked it and found a massive split right in the easiest spot to change, and I never noticed it because it was on the underside. This unit found it and I put a couple hoses on and smoothed the idle right out.Now that I've used this a few times it's pretty easy, zero to smoke test in 5 minutes. The hook is awesome, the inflatable bulb is awesome, the hoses are long, the alligator clips are decent, the oil port is decent, the oil view hole is awesome.The only small issue with it (that's not worth deducting even a single star over) is it has two speeds, and only the lower speed puts out smoke. If you wait for smoke on high speed you won't get any and might think it's broken. Click the button back to low and give it 10 seconds to start making smoke.Also you might consider getting a telescoping inspection mirror or some kind of endoscope. Making smoke come out the leak only takes 5 minutes, but actually getting your eyes on the hole can be tough.

Very reliable in checking all leaks in less than a minute heavy smoke came out of the port. flow and pressure are adjustable which expedite all leaks identified that save me time and money on lean code issue by not replacing unnecessary parts. Saves me hundreds of dollars and passed the smog
