Nice video thanks for sharing.when do you need to flush the system. I want to know because my car the compressor is cooling very nicely, but it’s making noise if I replace the compressor is it necessary to flush the system?

I have seen others using a home ac condenser chemical cleaner . The one which you mix with water spray on the condenser its makes bubbles and removes all the dirt even corrosion.After cleaning with this chemical they clean with gasoline then last with compressed air. During using The air conditioning will make the car smell gasoline in the cabin for two to three days .then to normal.

what stores sell 1 gallon of denaturated alcohol? Thanks

Is it ok to use petrol for cleaning liquid?

This looks really cool, Without watching your other video, did you check that the PCV can take whatever pressure it's getting? Just curious Thank you

I was able to find denatured alcohol fuel is that the same, and would be ok to use. Thanks

I like your do it yourself flush gun cylinder it’s even better than the ones they sell on the market because it looks like you can hold even more liquid 👍. If I was a DYI person working out of my garage and back shop for myself I would probably use alcohol to even though theoretically it’s not the best on aluminum parts there is a little corrosion factor thing going on there. But it’s only in contact for a short duration of time.
And when alcohol it combined with fast-moving compressed air there there’s a chill factor that goes on in compressed air does have a lot of moisture in it actually a extreme amount of moisture mixed with the alcohol and the chilling affect condenses out into water droplet that coat the inside with liquid water. But nothing that leaving it on the vacuum pump overnight will not take care of. But of course that means an overnight vacuum not a one hour vacuum.
You did a really good job of explaining the difference between the Microchannel parallel flow condensers that you cannot flush unfortunately you did not have a sample to show the people the larger round tube and fin construction you explained it good enough hopefully the majority of them will understand I often forget to explain process in detail
If you wanted to do even a slightly better job you could get a tank of nitrogen available at Airgas or commercial HVAC wholesale warehouse. After you did all the dirty heavy flushing work with your compressed air then you could come in behind it with dry nitrogen.
Crank up the pressure to 600 psi and use that you will get a higher flow faster velocity and of extremely dry nitrogen will help remove most of the moisture that you just introduced by using Shop compressed air. Of course at 600 psi the other side of the hose the condenser the evaporator or any device Hass to be wide-open not restricted so the item does not build up that kind of pressure it will just flow right through. And you need to also wear your protection because with that kind of airflow at that pressure and velocity it is deafening loud.
You should look into joining MACS And attending one of their yearly expose and seminars on air conditioning training and see all the available tools tips and procedures available and all the manufacturer products all under one roof.
It’s one of those mechanics training events that you should at least attend one time in your life. This year it’s being held in Orlando Florida by Disney. So if you have a wife and kids they could go have fun while you are attending training classes for three days. 👍

Excellent,thanks.

Denatured alcohol can contain methanol. Methanol is poisonous for ingestion and inhalation. Dumping it on the ground and then spraying it out of the A/C system under pressure aerosolizes it. You risk breathing the vapros or absorbing it via the skin. I get it, working on cars exposes you to lots of chemicals but Walmart sells 90% rubbing alcohol for a pretty cheap price and rubbing alcohol is ethanol, the same type of alcohol found in the beverages we drink. The other 10% is water, which I believe will evaporate with the alcohol when you're doing the flush or perhaps during the evacuation. I'd love to hear your guys thoughts on using 90% rubbing alcohol instead as I'm someone who's never performed a flush but may need to in the future on my wife's car.
