I have been working on cars and trucks for over 50 years. owned my own auto repair shop over 30 years. I have been smoking ac systems for a long time. However what I did is replace the oil in the machine with compressor oil instead of what ever comes in it. Saves a whole lot of time and guess work. Works great, never had a problem. Smoke em if ya got em.

More ac smoke tests like these would be awesome ive been wanting to try something like that

I may not know you, but that don’t matter- I’m just glad you’re healing up real well.

Great Video Boss! I never considered using smoke cause I can usually find it with dye. Thank you!👍 I Want That Smoke!😂

I have a new use for my smoke machine so I’m actually replacing a compressor for a friend and I used the vacuum to test for leaks and it didn’t lose vacuum really fast but the last mechanics that touched the car used some dye and it was seeping out the front of the compressor so the shaft seal was done but I’m going to fix and hope I have no leaks and if I do then I’ll use the smoke machine. In the past I’ve used compressed air and soapy water to spray around and I found the compressor shaft seal on my car had failed and I had just bought it so it helped me find it. I vacuumed the system for over an hour and I have had no issues with moisture and I replaced that compressor two years ago on my beater car and it works well.

When you see the plastic caps missing on the low and high pressure ports, you know a non-certified individual was messing with it. For us to be certified, we are taught that those plastic caps are not just dust caps. They are a line of defense for containing refrigerant.

leak in that area is one in a million, that's the low pressure area when the A/C is turned on. Just look for a oily area around the connections or condenser, soap bubbles work every time just like your looking for a leak in a tire.

Hi
Refrigerant leak detection is 1/ pressure leak only achieved with trace refrigerant and nitrogen pump ed to first 250psi then 300psi 2a electronic leak detector 2b ultrasonic detector 2c soap bubbles
3/ vacuum
Some detectors require constant movement some require resetting in clean air, some have annual replacement tips .
Vacuum testing is done with a micron gauge
Have you micron tested your gauge set, no mechanic shop does
R134a couplers leak badly unless sealed properly at least every 6-12 mths
RRR machines Recover Recycle Recharge has it been serviced ?
Vacuum pump oil changed and micron tested ?
Evacuating a contaminated system thats been open for along time should be at least over night 16 hrs minimum .Drier replaced
Due to the hydroscopic oil its always best to flush all parts except compressor and reoil compressor . After parts are flushed always blow through with nitrogen . All this will lower evacuation time by 75%

Thanks brother it was very helpful. Cheers

Using the refrigerant leak detector inside the airstream vents would indicate this leak. The smoke test isnt great if you coinsider moisture ingression inside the A/C system and only would indicate big leaks

Hi, I need make a consultation with you or hopefully one of your viewers can give me an advice on situation I have with my car. The old condenser was broken from the sides and a line was too. I did order a new one online, everything looks just like the original. The issue is that when I tried to connect the lines to the condenser they don’t fit in. The 2 holes on the ports are a little too tight or narrow, the line tip doesn’t go in all the way. So my question is, should I return and order a new one? Or will it work if I kind drill in the holes in some way to make them a millimeter wider? Or will that cause leaks after?
I really appreciate your help and time in advance.
Thank you.

Dang! Then some OLD mechanics. I heard after like 50-55 you gotta step away
