Thank you for good information. I also struggle for this kind of leak with dye. Most of cases I couldn’t find leak. Please make one video on bad ac compressor.
Another great video. My guess is it asks you to check for an Evaporator leak because R1234yf is combustible in the right concentration and that's why Evaporators for those systems are built stronger. Really enjoy the videos Bernie.
Hey, I just had a brainfart... Could your CO2 tester be also used for checking head gaskets? Lets say I have a vehicle that is overheating, and I think it is from the head gasket. Concrete test is to pressurize each cylinder w/ shop air, but this is difficult to do on a lot of V engines. Could your CO2 tester be used to sniff out this gas at the coolant reservoir bottle, and if so, how accurate would it be?
Hey Bernie, I have a question, not related to this video, working on 2002 Nissan Xterra. However, on the registration vin # comes up as 2002 Nissan Xterra but when I connect the scanner to OBD2 the ECU is reading as a 2008 Maxima with a whole different vin number. All the oxygen sensors are DTCs from P0152 to P0132. So do I treat this problem as a 2008 Maxima, because that's what the ECU is displaying, or as a the registration? Plz hit me back!
Bernie says:Then,I married this car . So f@k(en true... I don't think that is any mechanic, that they haven't married a car, at least couple of times, in their life. Personally, I have married a car,more than that.....
If you're flat rate, the new 1234yf machines are horrible. The all perform the normal vacuum test, if that passes, they instantly perform the 30% charge and want you to use a sniffer near the evaporator. If you perform that, and no leak is detected, then it goes back, recovers the 30%, vacuums and then recharges the system. Horrible for the tech and the customer if waiting, plus the cost is comparable to R12.
If people really care about global warming, they shouln't care about paying a higher fee. I charge much higher for this sytems and for diagnosis too. If it was up to A/C machine manufactuers, they would not add all this extra steps. It doesn't help either that 2 single companies have a monopoly on 1234yf.
I have such little faith in auto mechanics that I wouldn’t have let them charge it until I was ready to use it. I haven’t encountered a competent shop in my lifetime. Bernie is talking to people like they even have a clue how to do anything but a brake job. All parts changers. Not real mechanics
"That's 300 dollars that just escaped from this guy's wallet" funniest line I've heard in awhile. Nice Bernie 🤣
Good thing is not a Ford "Escape". 🤔
His tools located the leak, but his experience proves what works.
Thank you for another great video, Bernie.

Great video Bernie. i'm wondering can you use Co2 on R134a.
Yes
@@dustinryan867 Thanx.
Wow you are truly amazing. Thanks again for a very informative video.

You have a video on this channel with the same CO2 detector
awesome as usual thanks
Thanks for the great information
I agree with you. If you had a system with a very small leak, you would get a come back.
Great as always ☺️
IDK why the OEMs don't pick up this tool and require dealers to have it. As you noted other methods are just meh and mostly a crap shoot.
👍 great info

I think mercedes are using co2 as a refrigerant in their new models now as 123yf is flammable and too expensive.
Great video..! Keep it up..!
Why not nitrogen?
Because the atmosphere is already 74% nitrogen so the sniffer will be going off all the time

I use propane. Also very cheap and the combustible gas detectors r very sensitive.
Dye is good to get a service writer off your ass on a problem car, thats about all
