Hope you can get your issue fixed soon.

Our 2017 civic is also having cooling issues. Seems to be a common problem.

Ended up in the same situation today. Honda replaced the condenser for free but quoted me $1700 for the compressor and the local mechanic $800. Looks like there still isn't any guarantee that it would get fixed. What did you finally end up doing? I'm curious to know

Yea, I just did that off camera. Thanks for the comment and advice.

@@Sals_Garage I am new to this stuff and have a question. When attaching the hoses to the gauges and fittings does it matter which way? Each hose is different on each end when looking inside. One end is open the other has a little metal tab in the middle. Thank you

I believe the one with the metal tab in the middle goes to the gauges. That’s what I did.

@@Sals_Garage thanks Sal

Anytime. Good luck 👍

Thanks so much for the comment! Here is the temperature pressure chart I used, but there are many found on the internet: www.acprocold.com/faq/r-134a-system-pressure-chart/

I know right! It is HOT today.

Here you go: amzn.to/3UqnVcU

The blue line was already under vacuum for a few hours and that line was closed when the yellow line was disconnected.

Thanks for sharing!

It had oil in it already so I drained it out and used oil compatible with R134a.

Compressor can be used but change the oil to pag46 for compatibility

I have all the things you need to buy in the description in this video and in my compressor replacement video

Yes 👍

Thanks three years later, and it is still blowing cold. Very happy with it considering the cost.

I wanted to do it because it has been more reliable. No issues so far.

You didnt replace the ac condensor? Any problems to date with the switch back to R1234a?@@Sals_Garage

@@andyyepez7893 dealership replaced the condenser before. This is my third compressor and so far it’s been reliable ever since switching to R134a

Yes, 3 years later and still blowing cold. I only replaced the compressor since it was leaking again.

In part 1 the Freon was evacuated at a shop.

I used Pag 46 compressor oil. The OEM honda compressor oil for 1234yf is only available from honda dealership.

Ideally you don’t want to mix the two, have a shop discharge the old Freon then you can vacuum the rest out with a vacuum pump.

Thanks, 3 months later and still blowing cold! So grateful during this hot summer.

I changed the desiccant filter but not the expansion valve which is hard to access.

Yes, worked for me as well.

Still works great to this day, more reliable than the stock setup. Good luck 👍

Nice. Just to be safe I drained out the old oil and added the right amount for peace of mind. Good luck 👍

Hi Ride on - were you able to fix it on your own? I'm having the same issue and literally have zero knowledge to start with

1 filter, amzn.to/3Qeaiwp 2 cans of refrigerant: amzn.to/4b4uDvY

Still blowing cold and very reliable

Just the oil.

My concern was that Honda uses POE oil, instead of PAG oil. I don’t want to mess something up by mixing the 2 oils in the compressor / system.

@@Josh-yf9dw you’ll need to vacuum out all the old oil and refrigerant to start fresh without mixing.

No issues after three years still blowing cold.

Just change out the desiccant dryer filter and use the proper compressor oil for 134 (pag46)

@@Sals_Garage would that be considered the same oil you used to put into the compressor?

We did not. Still going strong over a yea later 💪

Still blowing cold 2 years later. Best decision I made for our Civic.

Do you have to replace ac condenser to do conversion to 134a or you need to replace it because of leak? I wonder if original one can be used as well.

@@Tahoe0512He said he had his system evacuated and the only thing required for the conversion is the oil and the refrigerant itself. The original condenser might leak because of defects though.

Hi. there is a Schrader valve in the center of the gauge faces for purging air out until refrigerant starts to blow out. Only needs a split second of air released. Good luck 👍

Regardless, could I leave the vacuum line disconnected (before adding dye or compressor oil) & open the low side in order to vent any air in the system & then close the vacuum line, add dye/compressor oil & move along? I bought the exact same vacuum set you mention & I'm not seeing what you could have been doing with your flat head screwdriver at the manifold.

@@Sals_Garage Thanks, I'll take another look at it.

When you release the cap you will see a little pin. I pushed that with the screw driver and air was released.

@@Sals_Garage Again, thank you Sal. I assume that you removed the gold "knob" from the vacuum line on the manifold & used your screw driver to push down on the Schrader valve?

Honda really should address the entire AC system. I even heard of some others with evaporator core leaks which is a pain to diagnosis and repair. For your case I would really try and fight with Honda to get them to fix the issue. Good luck 👍

Ended up in the same situation today. Honda replaced the condenser for free but quoted me $1700 for the compressor and the local mechanic $800. Looks like there still isn't any guarantee that it would get fixed. What did you finally end up doing? I'm curious to know

It still needs to be evacuated since there is a lot of pressure still in there. I paid a friend $30 for evacuating the lines.

Hi! Put some drops in through the low pressure port when you recharge the Freon 👍

@@Sals_Garage Thank you brother! What time dye drops do you recommend from amazon? Not really familiar with haha. I really don’t want to waste on either it being the AC compressor or Condenser. Salamat!

What in the he'll is the reason to take a better colder refrigerant and replace it with one that is not as good.? Makes totally no sense other then the massive price difference... why not just use air duster? (R152a) which is just as cold or colder then R12 and is like 8 bucks for a 4 pack of air duster at Walmart

@@jamesduffey4442 cheaper, more reliable, cools just as good as factory. Months later no issues. Can’t say the same about 1234yf on the civic, which always leaks for me (3 times).

No, you’ll need compatible oil

Sorry to hear. Most shops won’t do the conversion because legality concerns so you’ll have to do it yourself.

@@Sals_Garage I see ok. Would you still recommend doing it? Cuz it looks like people are running into the same issues again and having to get their compressor replaced 2-3 times. How's yours running so far?

@@vamshikalva1594 I recommended doing it because it is more reliable. 3 years later and AC still blows cold without leaks.

@@Sals_Garage thank you. Are you for sure blaming the refrigerant to be the culprit behind all the condenser and compressor issues? Secondly, I'm almost inclined to do all the stuff on my own. I literally have zero experience in cars. Could you tell where you ordered the parts and all that I would need and the best place to get them?

Yes I’m sure. Parts needed are in the description.

Yes still the same 1 year later. Can’t say the stock AC system was as reliable.

So this is possible to fully vacuum all of the oil and Freon from r1234y from the a/c components and fill new pag oil and R134a? I have a 2016 civic and this new A/c Freon just doesn’t last :(

That new Freon is expensive!!

@@ariesr4883 so far it has been going well. I recommend it but do at your own risk.

@@ariesr4883 yes, $500 for recharge of Freon is expensive!

Map Rey I don’t have a definitive answer. I suggest replacing all the oil with compatible 134a oil. I used pag 46 as seen on my compressor change video. Good luck 👍

It’s compatible with both. Haven’t heard that yet, hope it works for you. Good luck 👍

@@Sals_Garage did you put the same amount of refrigerant 134a in your car that the car requires for 1234yf? I heard you need less because 134a is more dense?

@@garnetvertican8179 we put a little less to be safe, used the recommended ambient temp chart in the video.

10x cheaper and more reliable than the newer refrigerant. 1234yf always leaks for some reason.

@@Sals_Garage My 2018 JL uses 1234yf and it doesn't blow COLD, even on 70s humid days. It blows cool, but it sucks in the summer since you have to basically blast it. The refrigerant is still expensive too.

Thanks for the tip. As a beginner I appreciate it.

I changed the compressor because it was leaking. Good luck 👍

@@Sals_Garage I found a TSB from Honda last night that the condenser is covered for 10 years now, going to try and get it serviced, if that's not the cause then we will still have to give this a try!

@@triptheroad good idea. You will need to pay a diagnostic fee for Honda to check still. Here in the Bay Area, Honda wanted $495 to diagnose the issue. If it’s the condenser then you get refunded, but anything else then you won’t get the money back.

@@Sals_Garage damn I know mechanics get screwed on diagnostics, but that's a high fee to put some dye and pressure in the system

@@Sals_Garage luckily our local dealership here in Fredericksburg VA didn't charge the diagnostic at all, they said they've seen so many come through with the issue that they aren't even asking questions 😂

Thanks, it helps offset my boring voice. 👍

Thanks for the tip 🙏

@@Sals_Garage You are welcome. Charging of high side pressures are usually done by taking ambient temperature( surrounding temperature) in degrees F, adding 32 to it and converting that temperature to corresponding gas pressure for the type of refrigerant used. That will now become your discharge or high side pressure. Charging is done while running engine to 1500 rpm and charging is stopped at that time, cool air temperature is taken to ensure Thermostatic expansion valve on the cooling side is working ok, temp will be close to 0 degrees C. The real cooling is experienced while car is moving as you have ram air also passing through the condenser located in front of the radiator. On idling only the fan may run if engine is hot but the test run will confirm everything for you. Good luck and I hope the above helps, years of experience. Go over all disturbed joints using leak detection fluid ( soapy solution) but formulated to prevent corrosion on pipes and there you have it.

@@Sals_Garage Dyes, a word of caution, a lot of manufacturers don't recommend it, if you have fitted a new compressor, confirmed no leaks then why use it? Dyes are flourocent, requires a UV light to identify due presence for leaks. If it's a profession then fine but otherwise leave matters simple.Fittings need cleaning after injection or it will be confusing for you or the next person and there are sniffers that sense leakage but suitable only if you do it as a profession, vacuum is ok on gauges but there is a torr gauge measuring minute vacuum, again out of scope for DIY.

Charging refrigerant R134a it's preferable to charge as vapour instead of liquid, though blends have to be charged as liquid in order to get the correct cocktail or mix of components.

@@pankajmakwana2300 Good tips for the avg DIYer. Thanks!

Depends on the ambient temperatures. I put 35 psi on the low side at 65 degrees Fahrenheit ambient temp.

All good, just drain it out and try again. Good luck 👍

Yea I don’t understand why Honda doesn’t acknowledge that other parts besides the condenser are problematic as well. The evaporator, compressor, condenser, and various lines can leak and it’s been attributed to the poor sealing quality with 1234yf. Hope you can get your issue fixed soon. I switched to 134-a for better reliability. So far so good. You can also use compressed air to fill up as refrigerant I heard.

@@Sals_Garage I just bought the car from Carmax March of this year. Luckily I did pay extra for their extended warranty and accordingly to Carmax all I have to pay is 50$ for repairs. I have 100,000 miles to get this ac issue figured out. I wonder if consumers are able to push lemon law on the New Car Dealerships for this issue. I know it will suck but as far as I know in Virginia if the same problem is repaired 3 time within 2 years the Dealership is responsible. Maybe it won't matter because Honda is a big enough of a corporation and this problem isn't affecting enough of the 'little man'.

@@miked8156 it’s been so hot this summer that we just wanted to fix it and not have to wait so long for Honda to do something about it if ever. I’m glad you have the extended warranty from car max. Good decision for AC at least it will pay for itself. The rest of the car has been very reliable.

1234yf sucks, my GF has a 2017 civic and we are having the same exact issue now. Of course the car is probably out of warranty now so we are looking at options as the refrigerant is expensive and not as good as 134 in performance. No wonder the used car market is insane, nobody wants to deal with all these new mandated inconveniences.

@@triptheroad If it were me I would research and buy an extended warranty. The Honda warranty has run out on my car but since I bought mine through carmax I went ahead and purchased their extended warranty. I think I paid $1700 for the warranty and in less than a year I have had $1900 worth of warranty work done through carmax.

This was part two. Part one was changing the compressor and the oil

I went back and watched it. Was that aftermarket compressor specifically a 134 compressor cause it didn't mention anything about yf to 134. Or did you just replace the compressor cause it was bad and just charged it with 134?

@@jarredallen2016 I replaced the original broken compressor with a new one and converted the refrigerant. No issues so far.

@@Sals_Garage ok. I'm just trying to see exactly what a "conversion" is. To I'd think that conversion means replacing certain yf OE parts with 134 aftermarket parts. But in reality, a "conversion" is just removing all the yf and charging with 134?

@@jarredallen2016 correct 👍

Sad reality. In California, gasoline cars will be banned by 2035

@@Sals_Garage phasing out something should be done slowly over the course of decades, so that it makes it a lot easier for the market to build upon a new infrastructure for it and allow people to become adapted to it. EV technology is great and all, but I don't think we are there just yet for it to become mainstream. If I can fill up an EV as fast as I could my gas car on empty to full, and if I was guaranteed a 400+ mile range. Ontop of the battery lasting 15+ years, then I'm sold on EV, but who knows when that will ever be accomplished. I'm a fan of hydrogen, it just makes more sense. Especially from an environmental standpoint where the cost of making energy for a bunch of EV vehicles has to come from somewhere. And that somewhere is at the expense of power plants to produce all that energy for 100's millions of EVs, that will be on the road in the future. Most of out power plants in the USA run off fossil fuel. So, I don't see how EVs are going to be better for the environment, when you're going to have all of these fossil fuel power plants having to produce more energy to power EV stations and EV cars in the future.

Thanks for the tip!

Eric the car guy says you turn until you see the needle move. Schrader valves can get damaged on some cars if you turn all the way down.

@@69ztang Thanks man.

Yea Honda is being very greedy about fixing this problem.

Yes, unfortunately this only covers the condenser, not the compressor. Honda denied my warranty so I fixed it myself.

@Joel Loeffler The a/c system in these cars are faulty from top to bottom. Next time you need it repaired, and there WILL be a next time, they'll likely tell you the compressor is gone as well and will charge you $1700...

Not only does it only cover the condenser, they will find any reason under the sun to not do it. In my case it was because despite it having a hole in the condenser they didn't believe it was my primary issue

It’s been a year so far since I have done this fix and the AC is still blowing cold and more reliable than the stock refrigerant which would have leaked out by now.

Thank you for posting this. I pinned this comment so everyone else can see it. Another thing I did was removed the 1234yf sticker on the hood and wrote down 134a so that anyone in the future who needs to service the AC is aware.

@@Sals_Garage It does not matter that you took off the sticker and wrote down R134 Refrigerant is now covered under the federal clean air act with a federal government it is considered a emissions gas just like the exhaust emissions from your tail pipe of your engine. Just like tampering with your EGR or your catalytic converter is now considered a federal offense tampering with a mission systems refrigerant gas is now covered under the same loss you are not allowed to reverse retrofit refrigerant anymore. It’s a $44,000 fine in any and every shop should and will turn down any retrofitted system for service. And it’s not just the aspect of a warranty the oils are different the refrigerant charge quantities are different in the operating properties of the different refrigerants are a little different so any failure to a compressor that burns them out is very expensive to repair on today’s cars Let’s take for example a Prius prime with a heat pump AC system or a volts wagon or a Audi or a Mercedes Benz with a heat pump air conditioning system If you burn out those AC compressors and litter the system with burnt oil and metal flakes from retrofitting it backwards to R1234 To R 134 The component replacement that is necessary condenser expansion valve flush all system accumulators all still annoyed valves lines and actuators three-way valves and electronica expansion valves would all be required to be replace the bill greatly exceeds $8000 to fix such a problem caused by somebody reverse retrofitting refrigerant gas.
