Do your own auto ac repair! Here, watch how Bruce Bonebrake quickly flushes the lines of an air conditioning system. Get everything you need to do the job right at AutoZone. - ยานยนต์และพาหนะ
I used to use a specialized flush designed for AC systems until a friend recommended Mineral Spirits which sells for 1/4 the cost of the AC flush and does a much better job in my opinion and won't harm the seals.
If you remove a compressor to replace an old oil from it (car was sitting without AC ~ for 10 years, how better to clean that compressor (I think it is working), with Mineral spirits or with that special Flush Liquid for flushing car AC? Thank you for the informative film.
I was the line going from the condenser to the evaporator. Do you need the flush the line going from the evaporator back to the compressor I would assume so but he was just emphasizing on the liquid line I don’t know what the other lines called that I’m referring to
which side of evaporator did you connect the air to flush it?
What brand is the solvent can you get it AutoZone
Where I can take a tank w/freon for disposal? They sell on Amazon those tanks, but I'm not sure where you can take that tank after?
I have a 2014 Toyota sienna! The ac siezed up and i'm replacing the compressor, condenser, and expansion valve! My question is that it has a rear ac system with a expansion valve! Do i need to flush the rear system as well and if i do i will need to replace the expansion valve!
I got a qoute from AAA and they suggested leaving the rear alone! Does anyone have experience with flushing mini vans ac system! Thank you!
Good day . How to wash a car air conditioning system?
The AutoZone DVD AC repair shows more than this one.Same guy but more details.They no longer sell it at AutoZone but you can buy a pre-owned one on eBay.
thank you very much
I bet you still shop there.
Hi friend, I am impressed by your video! are you interested in upgrading the halogen bulb to LED? recently I am looking for someone who can help me do the installation video, cause do many people they dont know how to install the headlight. If you can help me, please contact me anytime, Have a nice day!
no, this has nothing to do with inside the car air. They do make sprays that can clean your inside air you spray directly into the fan that sucks air through the evaporator
Will this take out all bug bomb pesticides out of ac system?
Hi first u flush with 100% evaporating hydrocarbon fluid .Use nitrogen to push the flush thru . There will be no chance of contamination [debris or moisture ] Most shop air has huge amounts of both . . If u used shop air then nitrogen blow thru is STRONGLY advised .This will shorten your vacuum time down as well by upto 6 hours . If u used compressed air, vac pump time is at least over night ie 12 hours .
late reply, but yes you can flush the condenser. You cannot flush a parallel condenser, but you can flush a serpentine.
KaoticFdr1 What kind is on a 99 grand cherokee limited with the 4.7 V8? I've replaced literally the entire AC system except for this, and it'll start out nice and cold when first starting it but after not too long it's just cool. I've had the freon level triple checked and it holds a vac perfectly. so, I'm thinking it's partially plugged. I have health issues that pretty much require me to have fully operational AC, Esp on the 80-95+ days. if I absolutely have to, I'll shell out the $$ for a new one and have it installed (I'm disabled- I have the knowledge, but can't do it physically) by my mechanic. If I need to replace it, I'll order it online as things are SO much more inexpensive than locally and I'll also buy the gauges w/hoses & vacuum pump. That much I know how to do for sure and I can do on my own even with my limitations. but do you think I should attempt flushing it first to see if it makes a huge difference? I love my truck, but being on disability is very tight financially and I don't want to have to unnecessarily replace parts if I can fix them. Your reply/input/advice would be GREATLY appreciated. Thanks ever so much!
I bought a used car and it has a smoke smell, would this help make the smell go away
No, replace the cabin filter instead.
do you need to do this to every ac componet when swaping r12 to r134 because that would be a pain in the ...!!????
Hate to say but YES. And you're right about it being a rpita.
At that point make a down payment on a 1995 or newer vehicle and kick your 1994 prior R12 vehicle to the curb.
Nice video. I'm still wondering though, what's a good flush solvent?
yea, use kitchen dishwashing liquid, I'm sure!
some solvents may damage the o-rings afterwards when you take that long trip. So they say; i'm not a chemist but k'm on!
Old school dude. Love it!
video uses a single stage 2 cfm pump . Considered to small for most automotive .
Recommend 2 stage 4--6 cfm minimum and 2 stage 8--10 for every day use
A 2 stage larger pump will pump out moisture alot easy and a better quality of job .
Approx how much psi?
?
sorry, forces air through the evaporator
Bruce Bonebrake is my wrasslin' persona.
Bruce Bonebrake was my 8th grade grunge band name. It was also the name of my college poetry jam group.
what liquid material use for flushing AC?
r141b
Use highly evaporative solvent based agents manufactured specifically for flushing out ac systems. Check out companies like Supercool, they sell it in various sizes but the gallon size containers are the most economical.
Hello
Can I make flushing for expansion valve and dryer ?
Please advise
NO
Flush pipes, condenser, evaporator and THEN install valve, filter drier, and compressor
Never flush the receiver/drier, accumulator, expansion valves, hoses with mufflers, or compressor. Modern condensers should be replaced and not flushed anymore because of the incredibly small passages contained within them.
@@StilettoSniper what age is considered modern? Is 2000 old or modern?
just replace them; they're not that expensive for having a good AC system working good for years to come!

Do you need an oil free compressor, or will an oiled one do?
Either one will work for this type of work. Although oil-free compressors typically have much shorter lives than oiled ones. All depends on what you plan on doing with the compressor. I have an oiled Ingersoll-Rand 60 gallon model that has lasted me 27 years and still looks like new, doubt I would have seen that type of life from an oil-free unit.
@@StilettoSniper Just using it for filling tires, small stuff around the house, and to blow stuff out like A/C parts when I get to do that project.
@@StilettoSniper I think he meant with regards to flush action here, not how long you want the compressor to last.
@@hhelmejor5485 And as I said in my reply, either an oil-free or a oil-sump type compressor will get the job done with regard to flushing.
But if someone is going to go out and buy a compressor so that they can do things like this, my point is perhaps they might want to buy one that is designed and constructed better, produces less noise and can handle the heat of compression much better. There is no question that a unit that has internal lubrication will excel on all three of those counts.
Use nitrogen when blowing out the evaporator or any component. If you use compressed air it may condense in the system which can cause damage.
Where Can i get nitrogen at for this purpose?
Atmosphere/etc. introduces oxygen and oil/fuel into a compressed condition which can and will diesel. This has killed people !
So I can't use an air compressor to distribute the flush and blow out my evaporator?
@@phillippardo5712 According to some of these guy you can't. I've watched a lot of videos and I haven't seen nitrogen used yet. I can see where air would be a problem. I don't have any nitrogen laying around. Maybe air on a low humid day? Or a really good dryer on the air compressor? Both?
@@kevino3190 Bummer. I already did it. Somebody also told me it will be fine because as long as you pull vacuum it should boil away the water vapor. Somebody else told me I didn't really even need to pull vacuum because the receiver driers job is to dry out moisture.. So I don't really know to be honest. I did pull vacuum though. And I agree, I haven't seen anyone use nitrogen. I don't even know where to get it.
This guy speaks insanely fast....
yea, its hard to keep up. but watch the sleigh of hands ... he's good; thanks for the vid
Maybe you just hear very slow.
nice
is it possible or recommended to flush the compressor.
No never flushed the compressor.
Really!
What can you expect from someone that doesn't know the difference between "your" and "you're" among other errors, yet still calls people stupid?
Never charge into the HP side????
+BlueboysGarage correct, it could reverse flow, pressurize the refrigerant can, and cause it to explode.
You should have also mentioned you shouldn't flush the A/C muffler if so equipped. Either replace or remove.
@silverbird58 Yeah bro, don't flush through the catalytic converter either :-)
yea my '87 gm high-side a/c line has a muffler on it. thanks for the info.
it sits right past the compressor in my car in case it backfires somehow.
Fiinding a phonebook will prove challenging
and always wear gloves..all in all good vid.

What will happen if you dont use the compressed air or nitrogen after the flush???
Any remnants of solvent must be removed from the system before recharging. Blowing dry compressed air through is one way to help evaporate the flush agent. Using a flush agent that is solvent based and evaporates quickly is another big help.
Atmospheric air has about 78% nitrogen, 18-19% oxygen, and the rest is CO2 and other trace gases. So, using compressed air will suffice as the majority of it is nitrogen anyway.
Industrial compressed nitrogen typically has a much lower moisture content.
Who the hell would be trying to do this labor intensive, dirty work with a neck tie on?
@It's Private Do you man, I'd rather ruin old clothes than nice stuff. Thanks for the how to.
by law you need to be epa mvac 609 to open mvac. flush with a inert gas not air .
Actually that liquid line was pretty clean, didn't need to flush it.
TheArfdog I disagree about not needing to flush the line. Even if it was clean, you would not know one way or the other, so it is best to flush it. And besides, if you look at what came out of the line (fluid in the bucket) you see small bits of metal particles. These particles would make their way back to a new compressor and damage it if not flushed out of that line.
@@ButchNackley compressor, orifice tubes, and expansion valve. the AC system must be TOTALLY CLEAN of metal debris from the old shot compressor and corrosion if any.
Uh, the sulfuric acid is caustic?? I think someone needs to go back to science 101. acid is low ph and caustic being an alkalai is high ph.
He blows compressed air ( filled with water,see below)thru and nothing said about nitrogen or how many microns to pull vac down to using a micron gauge ,where pulling system down to say 50 microns is about 5-7 grains of water which is far less than even a single drop of water (* this job requires a cert to do it legally)
thanks Einstein!
You won't never get that junk out of a condenser.
Why not just replace the lines
Your just listening to slow
This is a # HOTTTTTTT JOINT#
The way this guy flushes out the AC, says nothing how freon causes Ozone depletion. I thought refrigerant not supposed to be discharged into the air (atmosphere). HA ha sounds corny. Damn, O-zone is changing to Auto-Zone. you guys are killing us.
freon is not correct ,,,,refrigerant ,,,i am hvac cert tech, it was used by carrier in the past like today they call 410 a ,puron
and second i think the system was allready empty , he did not empty it in the air !. that is how to do it ,but now days not all condensers are flushable ok
lwnf360 go back to school moron
too much work
Or a lack of motivation
I just empty the whole system into the atmosphere. It’s free and a lot less of a headache. Autozone blows with their holier than thou business practices
So it wouldnt do any damage to the atmosphere. Because the shop say its gonna cost me 967$ to fix. I would do it myself
There is a $10,000 reward that anyone can apply for if they provide information to the EPA on anyone that vents refrigerant into the atmosphere. Make a (very short) list of all the people you know that would not dime you out for $10k. Something to think about before making such admissions on a public forum.
Why does doing auto work wearing a yellow, button-down, collared shirt bother me so much?
AutoZone SUCKS!!!
