EVAP and AC Leak Detection

Spring is almost here and that means successfully finding leaks in EVAP and AC systems.

Bernie This is a great product for our industry. Please do Not neglect the heavy duty truck industry. This is an invaluable tool for air brake systems. Thanks, the old school guy.

[@johnchambers12]

So your test solution is the only one that holds its surface tension across the bigger holes. That is impressive, thank you for your work on that one

[@amjadzidaoi4011]

Thank you very much for your time and effort to make the industry better and more lucrative.

Hi Bernie. Interesting video. It was great seeing you at TST Big Event in NY Saturday. Thanks for the picture and a ATS hat, Mario.

Just yesterday I did 275psi into system... I do remember that around 140psi the system was holding. But 275psi suddenly no. I thougjt... good, I ve saved money cos I have a leak... more likely I ve made the like by myown. Thanks for information, evap core job in front of me now....

[@timothybarnes533]

Thank you,for your hard work Bernie Thompson

[@mikechiodetti4482]

I finally saw why I had some problems locating leaks. Gees you find one but is it the only one!

[@DlNlW]

thank you for your work! I am waiting for new videos of engine diagnostics

[@spirokattan3655]

Great tutorial! Thank you Bernie!

[@ssrbob]

Wow, that's nuts. I never would have thought a solution wouldn't bubble at 20 or 40 thousandth. That would make diagnoses very frustrating.

[@АлексейДовженко-ю5ъ]

Thanks for the informative video!👏🏻

[@advancedleveldiagnostics]

Thanks for the demonstration!

[@slackthompson6984]

fabulous

[@danman9017]

thanks

[@proanswers]

Would like to have seen big blu in the testing. It's been my leak detection for years especially in micro leaks in hard to reach evap. Its clinging "surfactants" hold up to micro bubbles.

[@MDTA-AUTO]

Nice video .... I have emailed several times on your products and have had no response ?

[@Rubin4749]

Is there a PHYSICAL "brick and mortar" store I can buy your product at, in OKlahoma?? I would love to buy it, but not through the internet.

[@Pablo_Automotive]

Thanks a lot for share Mr Bernie

[@jordanboulay3780]

bernie i havent seen any videos in a while… is all ok??

[@vinnyc7613]

for evap how would a smoke machine do in this test

[@1MiketheMechanic]

There is a demonstration where they even know where the leak is and no smoke is visible but the Bullseye system shows the color change foam detecting the tiny leak.

[@vinnyc7613]

@@1MiketheMechanic but thats just it, u need to know where the leak is with the foam

[@johnnigro4536]

​@Vinny C that's where the sniffer comes in. Gets you in the ball park, foam hits the home run

[@jakemartin4305]

When mechanics become enieneers thats when you get great products love it 👏👏👍

[@charliemagoo7943]

Sometimes you can only access one side of say a condenser or evaporator. Therein lies a problem.

[@t.k5928]

Ong how does this cost $3900.00???

[@mikem5475]

3900 dollars wtf

[@northernpatriot9078]

bernie gtsy long time buddy i just bought tom dentons 5th edition ADVANCED AUTOMOTIVE DIAGNOSIS

[@Lambros_Stefaneas]

is it good?I am thinking to buy it ,too.

[@northernpatriot9078]

@Lambros Stefaneas it is I skimmed thru and the in depth approach to diagnostics is top shelf 😉

[@Lambros_Stefaneas]

@northernpatriot9078 Thanks for the reply. I am going to buy it.

Can my catalytic converter cause my 2017 Ford Transit to have multiple missed fire 🔥🔥🔥

On evaporators that you usually cannot get to physically, especially on vehicles, which of the majority of new ones that will take anywhere from seven hours to 20+ hours just to get access. You just use something like a Inforcon DeTech Stratus that reads refrigerant levels all the way down to the parts per million.. or the good old fashion H 10 refrigerant leak detector with a new properly adjusted heated diode sensor. Problem is most technicians do not know how to properly calibrate them, and dial in the adjustment for the Diode. High-pressure, nitrogen, and ultrasonic leak detector can pick up a leak from a few feet to a few inches away even if it’s can’t get direct access to it . And the other two high-pressure, 95% nitrogen, and either the helium or the hydrogen absolutely extremely sensitive and you do not have to get access to the Evaporator . They’ll pick up leaks so small and so accurately that usually when you just open up the car door you start to pick up the leak.. As for the bubbly leak detectors that are on the market big blue from viper technologies finally got a good formula that out does the rest . And for pressure in a evaporator there is no problem on all the new cars especially the ones that use microchannel Evaporators you can easily go to 175 to 200 psi pressure . When you were in Arizona on a hot summer day 110 115°F and you have the hot engine bay in the car interior gets heat soaked with the windows up to 160° on the inside - interior if you look up the PT chart for a refrigerant R134 at 130°F to your evaporator pressure will be 198 psi at 140°F. Your evaporator pressure will be 229 psi. This happens every day with vehicles hot soaked parked in shopping lot on the blacktop on hundred degrees plus days.. You hook up your gauge to a hot soaked vehicle and it’ll be between 190 200+ psi on the low side . Then there are those leaks that just don’t leak at static pressures and ambient regular temperatures. They only leak when the car is moving down the road vibrating and when you pull the car over and stay still in your garage with the hood up, it doesn’t leak Then you have those other leaks that only leak when one of the lines either gets hot from the hot, refrigerant, gas flowing through it or cold from the suction line in the middle shrinks or the middle expands, especially at rubber intersections, and it only leaks at that time but 100% completely seals up and stop leaking when it’s sitting in the bay just sitting there . Then you have those leaks like many of them that are pressure sensitive. They will not leak up to a certain pressure until they reach that pressure. They will not leak. . And then, as soon as they reach the pressure, they just pop off like a blow off valve.. some of them will be down to Refrigerant All the way near the zero within 24 hours and other ones will stop leaking when the pressure in the system cools down in the pressure goes below a certain pressure delete 100% stops. Those are the intermittently etc. booger to find . But the high-pressure nitrogen with helium and hydrogen usually find some every time and you don’t have to see and have access to the location . All the above methods my father taught me when I was a kid back in the late 1970s and early 1980s . These were all available they’re not new they’re not mysterious.. As for CO2, the same Inforcon, DeTech, Stratus, Reed’s Detector you can just switch out the module for a refrigerant for a CO2 leak detector. Extremely sensitive ultra sensitive. You even breathe in the area and you can set it off. The strata sleep detector is three leak detectors in one. I just simply slipping out one refrigerant sensor for a CO2 sensor, taking out the CO2 sensor and simply sleeping in a hydrocarbon leak detector sensor..

Interesting stuff Bernie. I've had good success with Hydrogen/Nitrogen mix and a hydrogen sniffer. Always looking to learn & improve. Is this for sale in the UK anywhere?
