I thought the vacuum pump and the jar with water demonstration and explanation was very good. Great video, well done and very informative. Got my sticker thanks.
Hey Eric, I just showed my wife (a chemical engineer from Stanford) your water boiling at room temperature demo and she said, “oh wow! That’s cool as hell!” I agree.
As a old retired AC man I was glad to see your vacuum demo to remove moisture. Maybe now the young guys can truly understand what the vacuum pump is really doing . Great job love your channel
I have never until today understood the reason for pulling a vacuum on the system. I thought it was to prove system integrity. Your demonstration was great. Thank you very much !
Hey, Eric! Just a DIYer here. I'd never heard of much less seen an example of water boiling because of vacuum pressure!! Thank you for teaching me something with each of your videos, and always giving me something else to research ;)
Fantastic demo! My partner and I watch your videos regularly as you're so good at explaining things and make interesting watching. It's great to see a garage that has good old fashioned values. If you can do it, I can do it - not without your vast knowledge on most things! xx
I know a lot. I learn stuff here and there watching your videos. Explaining how the water boils at lower pressures is awesome. I believe it is so much easier to understand diagnostics procedures when you know why things do what they do. Keep this up.
I have worked on cars all my life. It is awesome to hang out with you for an hour. I wish every mechanic had your standards. Really enjoying the videos!
Watching your videos is like sitting a auto tech school classroom. You are like an instructor that really wants you to learn. Tip o the hat to you sir.
Love watching these videos , I have done A/c work for 19 yrs and you hit the nail on the head with your explanation of water boiling at low pressure, would like to mention too to other viewers who might want to know that you should charge on the high side initially and if you need to add Freon / r134a it should be on the low side , and you should always leave system boil off for 5 mins before runningA/C otherwise compressors can hydraulically lock up and bust pistons up. I taught A/C in colleges for a few yrs it’s also a misnomer that A/C systems blow cold air this is an incorrect statement as an A/C system is a heat exchanger it blows cooler air as you put heat from inside car into Freon then expel the heat outside the car via condenser. This gentleman knows plenty and I’m glad he shares what he can with everyone, so people (lay or not) can understand
@Mike Studmuffin usually your are adding to a system with some pressure in it , pressure switch turns system off on low pressure. If system had no refrigerant in it, putting it in a vacuum is the proper way.
After watching your video, I changed my radiator in my 05 Pacifica, and found my cooling fan switch had been replaced and was also hanging by the wire. Luckily no damage to the condenser. I've repaired several things on this vehicle thanks to you and your videos. Much appreciated.
I love learning from this man. He doesn't mess up on this grammar at all and doesn't speak to fast to where you have to ask , what? If I was in New York I differently know who'd I'd take my car to go vist...your my Fav. Mechanic Teacher . Thank you
Eric it’s funny that you mentioned R2W. Because of his and your videos, I was able to go from no AC experience to successfully completing a complete AC overhaul on my beloved 95 chevy g20 conversion van, which has front and rear AC. I replaced the compressor, pressure switchs, evaporator, orrifice tube, expansion valve, o-rings, flushed everything, vacuumed, and recharged. I learned the hardway that Santech is not better than Acdelco, and your diagnosing methodology came out in me and I was able to use the gm service manual to deduce that my recent ac issue was due to a bad high pressure switch that I installed new during the overhaul of last summer. Well ysterday I completed and it is working correctly now, so I thank you and R2W!!
Got the tools delivered from Denny(Sataman Schmidt). I must say I'm impressed with TOPTUL's quality considering the price. The delivery was lightning fast-I had barely finished paying and I got an email with the tracking number-they came in 1 business day-impressive! I have bought a whole set of 1/2 inch 6 point impact 8 mm-32 mm shallow and deep sockets. They came with a swivel extension and a 6 inch straight extension. Denny threw the 15 mm and the 18 mm deep sockets in for free since they don't come with the set. Class act! Very happy to support Eric too for making these awesome videos!
Eric, your demonstration of lowering the pressure by using a vac pump was absolutely brilliant!! it was a very good scientific approach to demonstrating your point... thanks for the education from Eric's classroom. I have learned much from your videos, if i lived much closer to your shop I'd be a South Main Auto customer for sure... your fair and honest which is just good biz !!
the quality & pride is his mechanic work is truly inspiring. I love the Pacifica videos, as I own one of these poorly engineered pieces. They do ride nice though.
i love how Eric and Ratchets and Wrenches are so cool to recomend each other. I have always watched both channels regularly and I also recommend their videos to all my friends and family. BTW Eric thank you for sharing your tools with us. I love tools and especially a good deal on one or many! lol
It baffles my mind how customers decide where to spend and save money! "Give me the cheapest tyres and brakes you have and go ahead and fit me that £1000 sat-Nav unit!" Great video as usual, sorry about the Mityvac!
42:50 I will never forget the day I was at the shop and a Honda Civic pulled up with steam billowing out of the front grill and out from under the hood. I went up to greet the guy and ask him what I could for him (assuming that he was coming in right away after noticing the steam from the very obvious coolant leak he had). He wanted his free washer fluid top-off and nothing more. I said "Sir, are you aware of the steam that's coming out of the engine bay? You have a serious coolant leak right now." He said "Yeah I know, I just want that washer fluid for now." 😦 I put on my burn glove and popped the hood, and I could immediately see the top tank of the radiator was cracked and spewing steam and coolant. I topped off the washer fluid and asked him if he wanted a quote real quick on replacing the radiator. He declined. This was summer in god damned Tucson, Arizona and this guy drove away in that car with no care in the world. I was speechless. The way some people prioritize repairs/work is really whacky. I understand that the washer fluid was free and maybe he couldn't afford the rad at that time, but he didn't even want a quote. He was totally not concerned.
Shortcuts? "You can pay me now ---or you can pay me later". I'm all for beating the book, but that 's just criminal. And ---- yeah, that radiator should been done to save all that R&R labor all over again.
Great procedure video Eric. What's more interesting about any A/C major part replacement is many mechanics do not add any pag oil to the system often unless it's a compressor replacement job. I've watched them do it and I have also watched them evacuate the system in 10 minutes and call it good all while guessing on how many pounds/oz's of R134 to add. Once thing I didn't understand was how the radiator was damaged. Hard to think the condenser rubbed on it enough to do that to just the one side. It pays to have the right tools and equipment but most importantly, it pays that the shop uses their equipment to the fullest so that the finished job is done correctly. Yes, it is amazing to see our tools manufactured outside of the USA. Seems like that is changing for the future as import/export laws get updated so we may just see more USA quality sooner than later. Regarding "wrench sets", I also have noticed many sets of wrenches do not include the 9mm and 11mm size for some reason. Depending on the count of wrenches in a set, some come with the 11mm, not the 9mm and some with the 9mm not the 11mm. Can't figure why as there are plenty of 9mm and 11mm nuts and bolts on just about anything out there. Go out to buy them and individually, they are very expensive from $15 to $25 each.
Ill swear id love to work with you for a yr or two for free just to learn . Im sure alot of guys have said that but i really mean it . You are a great guy .
Your door bell rings allot i"m obviously not only one see a pro at work ! Keep being honnest lol retire wherever you please your a joy to watch thankyou for knowledge
I can remember my Physics teacher in high school demonstrating this same principle. Another way you can show it with the same equipment is if you were to wrap your hand around the bottom of your bottle of water it would really start to make that water start to get a rolling boil to it. Its an excellent way to demonstrate that principle, good job.
Another great informative video. Just a home mechanic so dont have an AC machine....interested to see you charge to the high side AND without the engine & AC running. Also appreciated your desire to do the job correctly...Many guys would not have mounted that relay or replaced the missing push pins...Kudos!! And the demo showing the moisture boil off was great!!
john smith you charge through your high side to keep liquid refrigerant off of your compressor valves. They cannot pump liquid. When the engine is running you can meter the gas with gauges to keep from flooding the compressor and knocking the valves out.
Gonna have to start calling you Mr. Wizard with your vacuum chamber water boil demonstration, which was really good by the way. Hell the only AC I ever had was when the windows were down. Good job as usual on the repair. Thanks for the video.
I have a 2006 Chrysler Pacifica . It has the power to move .But like you I prefer to have it start and good brakes and good tires . I have had Dodge trucks that were awesome and Plymouths that were crap .But it appears that Chrysler uses nothing but cheap parts .No wonder people die in accidents .Plastic doesn't take hard hits at 65 mph. Great video and as always you are very instructive . Well done !!!
Hey Mr. O., thanks for the video. A similar story for you, I did a condenser on an early 2000's Mercedes ML350. The system was totally discharged. When diagnosing the problem, I pulled a vacuum and it held, so I charging and the whole charge crapped out onto the ground (btw, PAG oil stains blacktop and stinks like cat piss). I found a plastic pull through (the kind that electric aftermarket rad fans use) that holds the center of the condenser tight to the radiator, it is a factory install so it's factory MB. Years of rubbing caused a nice sized hole in the condenser. A vacuum pulled the plastic thing tight to the condenser to hold the vacuum, when charging the system it let loose. Sometimes bad installs are from the factory too.
I like to see south main auto shop very interesting very professional work I bought 11 japanese car I do mechanical work a lot time south main auto shop the best place to learn honest gentleman good guy thank for all good work you do I also watch miss you taking matters into her own hands sir
Quality work is what kept me as a subscriber to this channel. That dangling relay is the kind of garbage work I see done all too often. I preach a lot about how great Eric O is about doing quality work just for that reason. I don't know when money out-ranked quality work but it's been down hill for decades now. Very disheartening.
Have you ever thought about becoming a teacher? Great videos, as a former student of an automotive program, your videos are helping me a lot. Thank you.
Hey Now! I have that exact mighty vac pump and it still works great! Thanks for the story about vacuum and reduced boiling temp....never thought about it before,...but it was great to have it pointed out that way,...I will look for top tul too
A long time ago I tested and calibrated compound refrigeration systems (Propylene over Ethylene) . for ic chip manufacture . Excellent video we used to chase the odd molecule for 24 hours
exactly why i don't trust shops in my area. I have had similar experience. shops here are more about money and not fixing it right. thanks for all the videos Eric.
I absolutely loved the water boiling under a vacuum demostration. I understood the theory but never seen it in action . In Miami during summer, AC is more important than the rest of the car.
Toptul was founded and made in Taiwan. Yeah, Taiwan but, this company is manufacturing some of the highest quality tools at a competitive price. Snap-On could sell their tools cheaper but, they want to you pay what they market. $110 dollars for a Snap-On 1/4 Ratchet, come on! Busting my balls trying to afford "good tools" so to speak. Lol I've come accross some of their stuff and honestly made me think about all the money I spent and just how comparable Toptul is, respectively to other brands. Stress tests, wear tests, etc. On another note, Great video Eric! From working in the car business for many years I've seen alot of people turn down some scary things that needed to be replaced. Paper thin rotors (in the rear LITERALLY paper thin), steel belt on tires fully shown, strut mounts fully rusted and not even attached and so much more. Some people want a death wish so, just fix what they came in for , even of its just a bulb or a/c fix! lol Learn so much from you Eric! Keep the videos coming. You motivate us all so much! From the guys over here in Rusty Ol' Wisconsin 🤙
Great Video Eric. I'm an AC guy that just replaced the motor in his Chevy Express work van. I thought taking the front off it was bad until I saw the Pacifica lol.
Great work as always Eric. I do find it amusing though that they'd fix the AC which has zero affect on the safety of the vehicle but they'll ignore all the front end suspension issues.
Your little boiling demonstration reminded me of a coffee moment in a small aircraft. I had a thermos of coffee from home with me on an early morning flight. I climbed to an altitude of about 7k feet and sat back and opened the thermos for some coffee. Damn if that stuff wasn't boiling over. Made a little mess. But the lower pressure of being at 7k feet made that stuff boil.
love watching your vids. I do some ac work on cars for family and friends. That with the hand vac was the best example I have seen. Keep up the good work.
WOW! Science experiment, great looking A/C leak detector, tornado story, replacing the condenser ! ! GREAT VIDEO! Oh ya. Finding the screwup by the other shop which started this repair. Those things happen!
GREAT VIDEO YOUNG MAN........LOVE THE PHONE RINGING. EVERY TIME IT RANG, MY WIFE WOULD ANSWER OUR HOME PHONE. NATURALLY NO ONE WAS ON IT. NOW SHE THINKS I HAVE A GIRL FRIEND.HA-HA-HA. SHE KEEPS ASKING ME WHY THEY HANG UP. I'M AN OLD RETIRED AUTO WORKER . WILL BE MARRIED 50 YEARS ON JULY 12 OF 2019........KEEP UP THE GREAT WORK AND SEND MORE VIDEOS. THEY ARE GREAT.......
Another terrific video. Simply outstanding content, production quality, and pacing. Eric, you are the talent that makes it work. Best part for me was to see how to get to the radiator and condenser as well as how to vacuum and charge an ac system.
South Main Auto Repair I just watched the newest ETCG video and you have taken the automobile repair youtube game to the next level with your videos. Congratulations!
I think we all have our own style is all. I see a lot of different cars every day, day in and day out. Always a mystery as to what we will tear apart next :)
Excellent video and the demonstration you did was awesome. Most times I also change the drier but in your case the condenser will still outlast the rest of the car. Maybe you will get the rest of the repair at state inspection time. I think that some people don't realize that steering and suspension wear can be dangerous for themselves as well as other people around them. I hope you document all those items and have the customer sign it since I got burned once.
34:02 Science class with Mr. O. That was a cool way of demonstrating boiling points and pressures. This is why it takes longer to cook at higher altitudes. Less pressure = lower boiling point. Because it requires less heat to boil water, you need to cook food longer at that lower heat.
I am a professional chemist. The demo at 35:20 showing that water boils a room temperature, if the air pressure above it is low enough, is a classic of first year chemistry. Sure enough the water boils vigorously at 36:30.
Great video Eric with lots of detail where anyone could do the job just like all of your other videos. And nice demo of how lower pressures will cause water to boil. Have a great weekend and don't work too hard!
@@SouthMainAuto Those self drilling/taping screws are worth at least 8 zip ties! Unless you are screwing into plastic. Then, the ratio is about 3:1 heh
Great video!!! Wow all that salt!!!!! I can't believe that cooling fan module job what ever shop that did it should pay for the condenser! The owner should have bit the bullet and replaced the radiator as well. The guy Jason that commented earlier made a valid point about the customer repairing the A/C system and stressing the leaking radiator. It can give out any day, she'll have to bring it right back to you, and pay for the labor all over again.
This video is educational as everything else you've made but I really enjoy the slice-of-life recanting of the tornado you had the night before. I can't put my finger on it, but I strongly feel that great mechanics are people first and technicians later. If you discard human moments like bald eagles, crappy mailboxes and road trips with your brother in favor of all work, all the time, then what legacy are you really working for? To summarize, you seem like a really cool dude and if I were ever in the area I'd love to be a crazy UA-camr to drop by for a quick visit. Cheers mate!
Great video. Does the receiver dryer need to be replaced as the system was open for an extended period? How can you tell when one has absorbed all the moisture that it can?
That is a good question? I don't know didly about ac as it never gets hot here ... but, I'd probably replace it on account ... but maybe pulling a vacuum gets all the moisture out of the dryer? Someone who does ac in Houston or LA should answer?
Customer logic: Yes fix the a/c but leave the radiator because the car isn't worth that repair..ok If you cant afford it now you will afford it later..and have to pay labor all over again
The term for lowering the pressure in a system to remove moisture is called "sublimation ". Pulling a vacuum in the system & then letting it rest in a vacuum for a period of time will tell you if you have s leak. If the pressure increases from it's resting state the system has a leak OR still has moisture in the systr6. Another way to dry a system is to pull a vacuum & break the vacuum using nitrogen. Then pull a vacuum again & retest.
Great video sir. Learn a lot watching your videos. I am currently studinging level 2 of automotive and next year for level 3 you get a "Top Tul" tool kit. That has a blow mould case. But has pretty much anything you need in it for beginners. Cheers from Christchurch New Zealand
Excellent video , and demonstration. It is a shame the customer did not want to replace or repair the radiator at this time, but then if it comes back , it will be another payday...hmmmm don't feel so bad after all..thanks Eric....
My wife hit a deer with her 3.5 Pacifica and I only pulled the top plastic off to remove transmission cooler, condenser, and the radiator. After watching how you did it explains why I had to buy a second radiator when I poked a hole in it trying to get the hose clamp back on with a screw driver because there wasn’t much room 🤦♂️
I barely got the town off your wore out shirt. Man you are up there! Farthest i been on 17 was painted post. I'm from middletown area, now live in georgia state. I like watching your videos. I'm an old mechanic from carburetor days gone by. I'm surprised cars last 3 years up there with all that snow ice n salt. I got a van here from mass thats so rusty i can't keep a ground on it....(sisters from mass.)
Great video and yes, I learned a lot about one of my vehicles. After seeing this, I will make some small repairs on it. Thanks for a good work and for being an excellent communicator.
Maybe you could have cleaned that ground connection with brake cleaner and then sprayed fluid film or battery grease to slow down the corrosion? Super good video.
After 45 years as a master mechanic I like watching mechanics with standards. Keep up the good work and your videos.
I love watching you work and trouble shoot. You are my fav mechanic.
I agree, he is inherently honest and does a real solid job! I would use him as a mechanic any day!
I thought the vacuum pump and the jar with water demonstration and explanation was very good. Great video, well done and very informative. Got my sticker thanks.
DC Rickerson Cool glad you liked it :)
I totally agree. Couldn't explain it better myself. You would be a great shop teacher. Ever thought about it as second career?
Also agree!
Why does it boil the water in the container but it doesn't affect his skin or hand? Just simple skin resistance?
How we made water in the Navy, pulled a vacuum on a tank with saltwater then capture the steam...viola freshwater!
Hey Eric, I just showed my wife (a chemical engineer from Stanford) your water boiling at room temperature demo and she said, “oh wow! That’s cool as hell!” I agree.
Thanks for explaining why a vacuum is necessary before charging. I always wondered. I thought that demonstration was excellent and informative!
As a old retired AC man I was glad to see your vacuum demo to remove moisture. Maybe now the young guys can truly understand what the vacuum pump is really doing . Great job love your channel
The vacuum demonstration is why I really like your videos. You take the time to explain why you do certain tasks.
I have never until today understood the reason for pulling a vacuum on the system. I thought it was to prove system integrity. Your demonstration was great. Thank you very much !
Eric. Props to you for 1) vacuuming the system (many would ignore this step and 2) explaining how vacuum causes water to disappear.
Hey, Eric! Just a DIYer here. I'd never heard of much less seen an example of water boiling because of vacuum pressure!! Thank you for teaching me something with each of your videos, and always giving me something else to research ;)

Indeed the concept of pressure and evaporation. I love HVAC. The science. Good demonstration of this concept, Eric.
Being a commercial AC guy that was a very good vacuum demo... Eric explained it perfectly....... Great jod

Your knowledge, combined with the proper tools, and willingness to teach really help to make your vides great.

Eric, you are real treasure. I am not sure if in the industry are more like you, I really hope so....but I still fix my thinks by myself.
I always learn something from you even when the video is 8 years old. Thanks.
Great procedure video Eric. What's more interesting about any A/C major part replacement is many mechanics do not add any pag oil to the system often unless it's a compressor replacement job.

Never could understand how water could boil without heat..."VERRY INTERRRESTING" ... Your vids are addictive in a good way.. Thanx mjg
Your door bell rings allot i"m obviously not only one see a pro at work ! Keep being honnest lol retire wherever you please your a joy to watch thankyou for knowledge
Great demonstration about water being boiled out of the a/c system and explaining how the inverse happens in the engine's cooling system. Thanks!

john smith Well we try to leave it better than we found it.
john smith you charge through your high side to keep liquid refrigerant off of your compressor valves. They cannot pump liquid. When the engine is running you can meter the gas with gauges to keep from flooding the compressor and knocking the valves out.
Thank's for giving us you're time, always enjoy watching you're vids. You have a knack of explaining things in a no nonsence way...

When diagnosing the problem, I pulled a vacuum and it held, so I charging and the whole charge crapped out onto the ground (btw, PAG oil stains blacktop and stinks like cat piss). I found a plastic pull through (the kind that electric aftermarket rad fans use) that holds the center of the condenser tight to the radiator, it is a factory install so it's factory MB. Years of rubbing caused a nice sized hole in the condenser. A vacuum pulled the plastic thing tight to the condenser to hold the vacuum, when charging the system it let loose.
Sometimes bad installs are from the factory too.
(Feeble attempt at humour) Scotty Kilmer would have warned you about a Benz product.
Working on some real junk there..Your a great mechanic..You breeze right through these tough jobs..
Very informative, especially the vacuum demonstration. Enjoy every video and your obligation to the customer.
I like to see south main auto shop very interesting very professional work I bought 11 japanese car I do mechanical work a lot time south main auto shop the best place to learn honest gentleman good guy thank for all good work you do I also watch miss you taking matters into her own hands sir
Quality work is what kept me as a subscriber to this channel. That dangling relay is the kind of garbage work I see done all too often. I preach a lot about how great Eric O is about doing quality work just for that reason. I don't know when money out-ranked quality work but it's been down hill for decades now. Very disheartening.
Have you ever thought about becoming a teacher?
Great videos, as a former student of an automotive program, your videos are helping me a lot.
Thank you.
Agustin Garcia No actually I haven't but thank you :)
This video reminded me how much I miss Mr. Wizard.
Very good demo on water boiling at a lower pressure Eric, explained well and quite clear. 👍
Thanks for the video just finished replacing a leaking condenser on an 07 Pacifica. Worked like a charm
You can teach an old dog new tricks. Thank you for another great video!
❤❤❤ Спасибо большое за чудесный репортаж с объяснением что и как делать.
Смотрю Вас в России❤❤❤
Hey Now!
I have that exact mighty vac pump and it still works great!
Thanks for the story about vacuum and reduced boiling temp....never thought about it before,...but it was great to have it pointed out that way,...I will look for top tul too
70carlton Good mine is swamped now you can send me yours :P
A long time ago I tested and calibrated compound refrigeration systems (Propylene over Ethylene) . for ic chip manufacture . Excellent video we used to chase the odd molecule for 24 hours
your leak tester just reminded me of a show i used to watch as a kid it sounds like the sonar on the sea view submarine wow how rare is that
Love when you toss in those tidbits of science that vacuum boiling off of water was awesome
exactly why i don't trust shops in my area. I have had similar experience. shops here are more about money and not fixing it right. thanks for all the videos Eric.
I absolutely loved the water boiling under a vacuum demostration. I understood the theory but never seen it in action . In Miami during summer, AC is more important than the rest of the car.
Liked the video.Safety is put on the backburner until some poor dude ends up in the morgue.
Toptul was founded and made in Taiwan. Yeah, Taiwan but, this company is manufacturing some of the highest quality tools at a competitive price. Snap-On could sell their tools cheaper but, they want to you pay what they market. $110 dollars for a Snap-On 1/4 Ratchet, come on! Busting my balls trying to afford "good tools" so to speak. Lol I've come accross some of their stuff and honestly made me think about all the money I spent and just how comparable Toptul is, respectively to other brands. Stress tests, wear tests, etc. On another note, Great video Eric! From working in the car business for many years I've seen alot of people turn down some scary things that needed to be replaced. Paper thin rotors (in the rear LITERALLY paper thin), steel belt on tires fully shown, strut mounts fully rusted and not even attached and so much more. Some people want a death wish so, just fix what they came in for , even of its just a bulb or a/c fix! lol Learn so much from you Eric! Keep the videos coming. You motivate us all so much! From the guys over here in Rusty Ol' Wisconsin 🤙
Your physics demonstration was spot on!
Great Video Eric. I'm an AC guy that just replaced the motor in his Chevy Express work van. I thought taking the front off it was bad until I saw the Pacifica lol.
ComfortPlus Heating and Cooling Thumbs up for changing an engine in a van!
best demastraytion ever. I was a ac teck for 15 years an never thought of that thank you.
Great work as always Eric. I do find it amusing though that they'd fix the AC which has zero affect on the safety of the vehicle but they'll ignore all the front end suspension issues.
What if sweat drips into your eye and you swerve and hit a car!! Haha, I’m just kidding, I agree with you, suspension should be a priority
Your little boiling demonstration reminded me of a coffee moment in a small aircraft. I had a thermos of coffee from home with me on an early morning flight. I climbed to an altitude of about 7k feet and sat back and opened the thermos for some coffee. Damn if that stuff wasn't boiling over. Made a little mess. But the lower pressure of being at 7k feet made that stuff boil.
love watching your vids. I do some ac work on cars for family and friends. That with the hand vac was the best example I have seen. Keep up the good work.
Thanks for the 'low boiling point under vacuum' demonstration. Very interesting, never knew that.
lascar48 Need to get Eric a white lab coat for his little science segments.
Matt Bartholomew Lol I don't think me and white get along.
@@CALVINLNIKONT Pressurised vessels are used at elevation, same principle as a Pressure Cooker.
WOW! Science experiment, great looking A/C leak detector, tornado story, replacing the condenser ! ! GREAT VIDEO! Oh ya. Finding the screwup by the other shop which started this repair. Those things happen!
it really helped me.I changed the radiator without any problems and was able to do it without disconnecting the A/C
Thanks Again!
Excellent videos. i have an 04 Pacifica amd have spent a lot of time underneath it. your videos have helped.
GREAT VIDEO YOUNG MAN........LOVE THE PHONE RINGING. EVERY TIME IT RANG, MY WIFE WOULD ANSWER OUR HOME PHONE. NATURALLY NO ONE WAS ON IT. NOW SHE THINKS I HAVE A GIRL FRIEND.HA-HA-HA. SHE KEEPS ASKING ME WHY THEY HANG UP. I'M AN OLD RETIRED AUTO WORKER . WILL BE MARRIED 50 YEARS ON JULY 12 OF 2019........KEEP UP THE GREAT WORK AND SEND MORE VIDEOS. THEY ARE GREAT.......
Another terrific video. Simply outstanding content, production quality, and pacing. Eric, you are the talent that makes it work. Best part for me was to see how to get to the radiator and condenser as well as how to vacuum and charge an ac system.
Sandbag1300 Thank you sir!
South Main Auto Repair I just watched the newest ETCG video and you have taken the automobile repair youtube game to the next level with your videos. Congratulations!
I think we all have our own style is all. I see a lot of different cars every day, day in and day out. Always a mystery as to what we will tear apart next :)
Loved the phase diagram experiment. Great explanation. Any update on toptul long term durability. You still love them years later?
Excellent video and the demonstration you did was awesome. Most times I also change the drier but in your case the condenser will still outlast the rest of the car.
Maybe you will get the rest of the repair at state inspection time.
I think that some people don't realize that steering and suspension wear can be dangerous for themselves as well as other people around them. I hope you document all those items and have the customer sign it since I got burned once.
wysetech2000 Yeah I did and I also provide an estimate on needed repairs. C.Y.A. I say, (cover your a...) well you get it.
34:02 Science class with Mr. O. That was a cool way of demonstrating boiling points and pressures. This is why it takes longer to cook at higher altitudes. Less pressure = lower boiling point. Because it requires less heat to boil water, you need to cook food longer at that lower heat.
Liking the longer video's - Thanks Eric!
I am a professional chemist. The demo at 35:20 showing that water boils a room temperature, if the air pressure above it is low enough, is a classic of first year chemistry. Sure enough the water boils vigorously at 36:30.
I really enjoyed this video Eric. You are the "MAN" !
Great video Eric with lots of detail where anyone could do the job just like all of your other videos. And nice demo of how lower pressures will cause water to boil. Have a great weekend and don't work too hard!
stuzman52 I was gonna demonstrate how you can boil blood like that to but couldn't catch the neighbors cat haha
Funny guy you are!!! Maybe next time have some cat food and you'll be in business LOL...
Hey now your thinking :)
Looks like the fan relay job was a scotty kilmer repair. NOW JUST GRAB THE ZIP TIE AND GRUNT AS YOU TIGHTEN IT! UHHH
Jacksonkellyfreak Haha No comment...
Does he do that kind of stuff?
@@jerryferrelljr8892 Unlikely given he was a Houston mechanic on UA-cam for ages. Now out of Tennessee.
@@SouthMainAuto Those self drilling/taping screws are worth at least 8 zip ties! Unless you are screwing into plastic. Then, the ratio is about 3:1 heh
Great video!!! Wow all that salt!!!!! I can't believe that cooling fan module job what ever shop that did it should pay for the condenser! The owner should have bit the bullet and replaced the radiator as well. The guy Jason that commented earlier made a valid point about the customer repairing the A/C system and stressing the leaking radiator. It can give out any day, she'll have to bring it right back to you, and pay for the labor all over again.
Stanley Hill Yeah she will but when every thing is on a budget it is what it is. Car needs a lot of work still too :/
Yea I can relate, it definitely needs a lot of work I think those other Pacificas you worked on were in better condition 😉
Seems so huh. Well the one with the headlight issue I did replace the frame in once all ready
Great demo with the Mity vac pump. I know the theory, but nothing like actually seeing how moisture boils and dissipate in a vacuum.
This video is educational as everything else you've made but I really enjoy the slice-of-life recanting of the tornado you had the night before. I can't put my finger on it, but I strongly feel that great mechanics are people first and technicians later. If you discard human moments like bald eagles, crappy mailboxes and road trips with your brother in favor of all work, all the time, then what legacy are you really working for? To summarize, you seem like a really cool dude and if I were ever in the area I'd love to be a crazy UA-camr to drop by for a quick visit. Cheers mate!
Thx for your vids man, always explained perfectly and great quality vids. I own a Pacifica and it always has issues.
You forgot to use brake parts cleaner....very informative as always!
arcdraw OH MAN You are right!
You're a wonderful teacher. This video is top notch.
Great video as always! Thank you for recording this, I know it was a hassle but we appreciate it! Keep up the good work!!!
TheTexasCoder Well thanks for watching them :)
Now then I know why vacuuming required from lines, thanks mate.
Yep that is right
Great video. Does the receiver dryer need to be replaced as the system was open for an extended period? How can you tell when one has absorbed all the moisture that it can?
That is a good question? I don't know didly about ac as it never gets hot here ... but, I'd probably replace it on account ... but maybe pulling a vacuum gets all the moisture out of the dryer? Someone who does ac in Houston or LA should answer?
Customer logic: Yes fix the a/c but leave the radiator because the car isn't worth that repair..ok If you cant afford it now you will afford it later..and have to pay labor all over again
Real as real can be ...with all the crap that we go through working on todays vehicles . Love the look at 7:18 ,priceless !
Another great video with lots of detail and tips and tricks thrown in. Thanks for taking the time to make these.
The term for lowering the pressure in a system to remove moisture is called "sublimation ".
Pulling a vacuum in the system & then letting it rest in a vacuum for a period of time will tell you if you have s leak. If the pressure increases from it's resting state the system has a leak OR still has moisture in the systr6.
Another way to dry a system is to pull a vacuum & break the vacuum using nitrogen. Then pull a vacuum again & retest.
Great video sir. Learn a lot watching your videos. I am currently studinging level 2 of automotive and next year for level 3 you get a "Top Tul" tool kit. That has a blow mould case. But has pretty much anything you need in it for beginners. Cheers from Christchurch New Zealand
TopTul makes some of the best tools I have seen! Good luck in school!

Excellent video , and demonstration. It is a shame the customer did not want to replace or repair the radiator at this time, but then if it comes back , it will be another payday...hmmmm don't feel so bad after all..thanks Eric....
***** Well we can only do what it was here for and what they budgeted for too. It will be back at a later date I am sure.
My wife hit a deer with her 3.5 Pacifica and I only pulled the top plastic off to remove transmission cooler, condenser, and the radiator. After watching how you did it explains why I had to buy a second radiator when I poked a hole in it trying to get the hose clamp back on with a screw driver because there wasn’t much room 🤦♂️
I barely got the town off your wore out shirt. Man you are up there! Farthest i been on 17 was painted post. I'm from middletown area, now live in georgia state. I like watching your videos. I'm an old mechanic from carburetor days gone by. I'm surprised cars last 3 years up there with all that snow ice n salt. I got a van here from mass thats so rusty i can't keep a ground on it....(sisters from mass.)
Great video and yes, I learned a lot about one of my vehicles. After seeing this, I will make some small repairs on it. Thanks for a good work and for being an excellent communicator.
Maybe you could have cleaned that ground connection with brake cleaner and then sprayed fluid film or battery grease to slow down the corrosion?
Super good video.
