How To FIX Your Subaru AC For CHEAP! 3$ O-Ring FIX! Quick and Easy Tutorial!

I Did a video about 4 years ago on this same topic. I recharged my AC system and had cool air for about 20 minutes...It didn't take long for the refrigerant to leak out. This time around, i show you how to replace the 2 o-rings located inside the AC compressor. Months later my AC is STILL blowing cold air. You have got to try this, it's about a 3 dollar investment plus the cost of refrigerant. I can't believe it was so simple to fix afterall.
I used a generic bottle of R134A from Autozone but you can also find it on amazon. (links below)
I also bought the o-rings directly from the dealership. Again, Amazon does have them as well, but a bit pricier.

The mechanic wanted $550-$600 to diagnose and fix my ac. I spent less than a hundred bucks for r134a with dye, glasses and a uv light to indent icy the leak and o-rings. I love KZbin!

[@fosteroak]

You just saved my butt! Tomorrow we drive 23hrs to S Dakota for college and my son’s car had no ac. I saw the leak at the compressor joints and you explained perfectly how to do it. You gave me the confidence. Thank you! 🤟🏻

[@magsteel9891]

I fixed my 2011 Forester a/c today by changing the O-rings. Part numbers for this vehicle are 73039TA040 discharge side, 73039TA020 pressure side. You can energize the compressor clutch by disconnecting the wire on top of the compressor and using a jumper from there to the battery +. The system had no pressure so there was nothing to recover. After the fix I used a vacuum pump for 20 minutes, then let it sit for 10 more to see if the gauges moved. After that I charged the system. Tools used were from Harbor Freight, Pittsburgh Automotive 3 CFM Two Stage Vacuum Pump, Pittsburgh R134A A/C Manifold Gauge Set, a R134a can tap, and R134a refrigerant. The system takes about 16oz, check the sticker under the hood. You can also watch the low and high pressure gauges to make sure you stay within the pressure limits for the ambient temperature. The compressor stopped buzzing as the pressure approached normal. I used LocTite blue on the bolts, I'm pretty sure they had thread locker residue on them. Just torqued by feel, they are not big bolts.

[@coltonnorman5238]

Curious what is the purpose of the vacuum pump after you recharge the system?

[@zacharyhaueisen2481]

Only 30 secs in, and u just seem like a cool dude so ima sub. Thanks man

[@06wrxdude]

I appreciate that! I’m an alright dude!

[@BillWinterberg]

Thanks for the video and the part numbers of those O-rings, I appreciate your additions to the WRX community!

[@jjclarkson3261]

Excellent video with clear information and easy to follow video. Keep up the great work!

[@gregorymark6014]

He's absolutely right, it is illegal to vent refrigerants into the atmosphere. One can take their vehicle to a local shop and have the refrigerant properly recovered for $55 or so. I have an EPA MVAC Technician Certification, I don't recommend "leak sealants" as the refrigerant passages are so small in modern automotive ac systems that one may end up with more problem than they solved. The O-Rings are a know leak source (definitely use the OME parts). I do like the video but I would never use the stop leak and apparently/fortunately he didn't either!

I agree, I always get mine vac'd out. Depending on whether or not if I add oil, compressor ect. I'll do that stuff myself. But the vac and charge, I leave that to someone with a machine. Don't have the space for a machine bit of a gypsy. But to anyone else. Everything but the gasses you can do yourself unless you've got the recovery and charge unit.

[@ragnaroksangel]

Curious if the EPA told you about their colossal failure with the DEP system in semis? Did they tell you about the lithium mines making these bullshit electric cars? How about how precious metals in your cats will conserve on greenhouse gases while the mining to get those materials is FAR worse than what all cars are putting out? Dude fuck outta here. Just like hair spray was the cause of the hole in the ozone layer back in the day. Oh no! Couldn't be major corporations getting subsidies while fucking our environment to hell and back. Must be the everyday person... Using hairspray... Dude fuck outta here. You and the EPA.

[@curbdog3036]

It worked, thanks! I thought I bought the right gasket from subaru but had to go with the green one from the auto store AC section when it was too small. $40 for the can of ez chill to recharge it and super cold.

[@zerotwopingbob]

I’m pretty sure this video would save a lot of subie owners out there including me here

[@lac3904]

&I

[@hah1738]

When reading the pressure, the correct value is when the compressor is on, when it's off it will read much higher than it really is. From empty it would need at least 2 cans of 12oz, so it seems like you've read the high value when the compressor is off rather than the real value when the compressor is on.

[@phillip806]

Thank you for being so thorough with the procedure and follow ups! Did you have a separate video for the vacuuming part?

[@06wrxdude]

Unfortunately no… I’m winging it… so far so good years later 🤞🤞

[@kimcheefists]

A vacuum really should have been applied before adding any refrigerant into the system. Any moisture in the atmosphere when the lines were disconnected is now inside the A/C lines which will eventually cause corrosion inside the lines or even compressor failure. The proper way of recharging the system should have been done with A/C gauges on the low and high side..

[@charlesmartinez2999]

I agree with you, I worked for Snap-On Tools equipment technician a few years back. Our A/C refrigerant recycling machines would pull a deep vacuum, hold the vacuum to verify for no leaks. Then shoot the proper amount of R134a into the system. I live in Las Vegas and this would not fly in the desert.

[@06wrxdude]

Well clearly I’m no professional...I’m just another DIYer getting the job done, With the same results in the end 👍

[@chrisbaskett808]

Not really in the long run

[@jordanriggs2745]

​@06wrxdude maybe the same temporary results, but in addition to now having the moisture from the atmosphere in your system which can turn your oil acidic in time and eat away at your system, you also have a system full of air that you dumped refrigerant on top of, that now runs a high head pressure and will eventually cause more leaks down the road. So not the same result. Vacuum is absolutely crucial. But I hope she's still holding up for you man! Great video besides that🤌

[@bmc5180]

​​@@jordanriggs2745 You mentioned the possibility of his oil turning acidic, but is there really any oil left in the system to begin with? I figure he lost pretty much all of his oil and refrigerant due to the leak. I guess it's possible there could have been some residual oil, maybe an ounce or two at most. But I would assume if (when) his system fails prematurely it will be due to the lack of oil...as well as damage from the moisture and air in the system. But I'm still learning this stuff, which is why I wanted to ask a follow-up question to your response.

[@VenomDub98]

Bless you for all the videos you make on these subies.

[@fatsubie7604]

Awesome video. I like the way that you waited to make sure it worked.

[@1marcelfilms]

On my car it wasnt an o ring that was leaking, it was the aluminum that was corroded. Scraped it and lightly sanded it and coated it with silicone grease so it wont corrode in the future and replace the o ring anyway. so far so good

[@06wrxdude]

Oh glad you figured it out!

[@Z3CHYD]

I did the same thing with my 07 impreza when I got it, a quick trip to Advance Auto for a pack of random sized o-rings and mine still blows cold, and its been a couple months already!

[@segredosdotiosam9989]

You need to evacuate the system with vacuum before charging . the moisture in the air left in the system can cause corrosion .

[@06wrxdude]

That’s what Im hearing. I hope I don’t regret it later down the road… Thankful my AC is still blowing cold after all these years.

[@tkkcali]

Had ac fixed. Leaking o ring. 2016 crosstrek. 50000 miles. Told these leaking o rings were a problem. I guess shop checked for leaks, recovery , refill etc. 323 dollars. Should have done it myself

[@06wrxdude]

Bummer! I guess the next time you’ll be fixing it for free… 🤷‍♂️

[@samerawaragi3041]

Thanks for your video. How frequent your A/C turns ON and OFF on idle on hot and warm temperature? Thanks

[@juanarroyo465]

Hey thank you for the video, was just wondering which o ring is for which hose? Theres 2 different part numbers to each ring so i dont wanna use the wrong one on the wrong hose

[@06wrxdude]

Sorry for the late response… High Pressure Side A/C Hose o-ring: 73039FA100 Low Pressure Side AC Hose o-ring: 73039AA300

[@timothylavender191]

Hey bro been skating any? I just got a subie, 2006 impreza 2.5i wagon. Those universal AC 134 adapters don't fit!

[@drunkenmaster1313]

Hoping this is what will fix mine too. Was pleasantly surprised that we have the same stereos in our turbo subies.

[@lawrencecavens5760]

If this is a Subaru another place you need to check is the high side schrader valve for leaks as my Forester had this problem. I was able to change it and wha-la !! leak was gone, But yes to the O rings as you shown here they are known to cause leaks too...

[@Flatfourdetailing]

In the same boa as you. Car is blowing cool/warm air. Can't have that with a baby in the car.

[@bryceholland2845]

I noticed he didn’t pull a vacuum what howcome? Will I have to pull one if I have the same issue?

[@JoshDambuleff]

Was the compressor making a lot of noise and kicking on and off? That’s the problem I’m having. Any ideas?

[@boosted_donkey]

I hope this is my issue. I replaced my compressor with the provided aftermarket o rings and heard a small hiss at the compressor. Then noticed the o rings that came with didn't look as thick

[@leahgillis7444]

So have an 08 Impreza wrx and ac comes in and out. Compressor does kick on and off. Had the Freon flushed and recharged and still having issues with it. What else could I look for?

[@magsteel9891]

I hope this is my problem too. Thanks for the video. But dude, you need to get a vacuum pump and manifold gauges to do this right.

[@tptm100]

Would I have to put the cars a/c system into a vacuum first and then add the refrigerant????

[@06wrxdude]

Yes. That would be the professional/ correct way of doing it… 🤫

[@준-d5q]

What year and model is your car? I have 2006 outback and am having a problem with A/C leak as well.

[@06wrxdude]

2006 WRX. I’d check those o rings that I swapped out. Car has been blowing cold ever since!

[@AegisZer]

Just want you to know, the o-rings for yours isnt universal. They caused leaks in mines but funnily enough the green autozone specials worked.

[@sandeepmajeti5783]

Hey my subaru out back has cooling issue ( I feel only hot air) . I tried with AC charge it worked for 2 days and repeat same issue .. please suggest .

[@marcelodelpuerto395]

Sounds like a leak!

[@06wrxdude]

Replace o rings on the low and high pressure ports. Evacuate system first…

[@howdyags5149]

Awesome video 👍! It helped a lot!!

[@shamwaymoonyos9578]

Nice job man :) I also like that Sony head unit you got there. Been running a Pioneer AVH-X5600S from Crutchfield with steering control hookup in my 2015 WRX. I could not stand the base head unit I had on my car. I'm normally not a complainer with the head units in cars but I hated it enough to get that around 6 months after getting the car. So far it is holding up well. Though if I could go back I'd just not bother getting that same unit since it has a DVD player I NEVER use lol. Waste of money. Another critique of that stereo is it doesn't have great active noise cancellation so it picks up much of the road and cabin noises. Audio quality is pretty good though. Stock speakers and rest of audio system is stock.

[@raydolinger1980]

Always vacuum pump the system before dumping freon in... moisture is all up in your system now... compressor will fail soon.. :/

[@gsabella4]

Hey! Thanks for the video. What's the importance of jump starting the compressor/ac clutch like that? @8:00. If i don't do that, will i run the risk of overfilling or damaging the system?

[@06wrxdude]

Thanks for watching! Since my system was empty of refrigerant, the pressure switch would never be activated because it needs some pressure to function and kick on the compressor. Jumping that switch allowed me to start filling the system right away. I’ve heard you can indeed damage the compressor if you try to refill without it being kicked on first. I hope that makes sense…

[@gsabella4]

​@06wrxdude yes that makes sense, my 08 Forester seems to be completely out of refrigerant due to a leak. I'm trying to find my AC sensor ....

[@06wrxdude]

Aww bummer. Hopefully it’s only the orings that need to be replaced

[@gsabella4]

I think we're in business!!! Did you keep the ac switch jumped while filling the system?​@@06wrxdude

[@gsabella4]

​@@06wrxdude I think we're in business!!! Did you keep the ac switch jumped the entire time while filling the system?

[@MiguelGarcia-go7tu]

Great video. Subscribed. Do you have the torque for the two 12mm bolts of the high and low pressure lines? Thanks

[@06wrxdude]

I do not… that might be a quick google search away to find that answer. just use your judgement. Not too tight and not too loose …just snug 🤷‍♂️

[@Mario-hd5se]

Hey my ac went out the ac lines don’t even get cold when I turn AC on could that be the compressor I was told. The system was full too.

[@06wrxdude]

Could be. Does compressor even click on and off ?

[@Stevesbe]

You didn't pull a vacuum on the system before charging that is pretty important

[@Kradle]

Yo dude. I did this myself and I didn't vacuum down the system before refilling...how's it holding up for you?

[@06wrxdude]

Yes as you know neither did I. My system was completely empty. I guess consider me lucky? Anyways, I actually kicked on my AC the other day and it’s still blowing cold years later. I couldn’t believe it! 👍

[@stevensiwinski]

Good video. I'm going to have to try this fix!

[@annafekete9313]

What vehicle is this? I called Subaru and the parts were slightly different for a '17 forester, so I assume not that.

[@MaddoxMelton]

Looks like a Hawkeye wrx. 06

[@tarwashsomeonestolemyhandle]

what about the one going to the radiator?

[@neilaleksandrov2655]

i understand everything minus why would you mess with the pressure switch? why do u need to manually reset it, shouldn't it automatically detect whether or not there's pressure in the system, otherwise whats the point of it? seems confusing

[@06wrxdude]

The compressor won’t automatically turn on without proper pressure in the AC system. Therefore the pressure switch had to be bypassed which turns on compressor and allows the new refrigerant to be pumped in properly. Once you have sufficient pressure in system, the switch no longer needs to be bypassed.

[@Shad_07]

I have a prob with my 1999 subaru forester' the AC take's time to start when i turn it on' after i start the vehicule

[@zumadale]

Don't you need to evacuate the system before recharging???

[@06wrxdude]

A professional would… in my case, the system had already been emptied due to a leak from either the inlet/outlet side of the compressor.

[@garymorrison1009]

ok so my dealership told me that the system has to be evacuated before filling it from a can, otherwise ‘moisture’ (humidity I guess?), will enter the system and freeze it off while in use. Anyone know if that is a concern or not?

[@06wrxdude]

Yes that would be the correct way to do it. Mine already had a small leak coming from orings so my system was already empty.

[@bryllegascon7939]

Is this o-rings fits to crosstreck 2015?

[@drsyn67]

@06WRXDUDE - I have an ‘05 Legacy 2.5 I wagon. My A/C clutch is not engaging at all - was yours also not turning on & off? It does spin by-hand, so it is not seized-up.

[@06wrxdude]

If your system has lost all of its refrigerant, your AC compressor will not engage. You can test it by using a jumper like i did in the video around 6:00 mark. This will rule out any question if your compressor is bad or just not activating due to zero pressure in system. Good luck!

[@marcelodelpuerto395]

My Forester's wouldn't turn at all until I added quite a bit of refrigerant, the it started up. It was screechy at first but smoothed out after a minute.

[@jerryallright77]

Bro. Great video. Question: my car when with AC on, feel like the clutch is hard and don't drive as smooth . What could it be . ?

[@joelaransevia4592]

A car's A/C is normally powered by a belt connecting to the engine. When A/C is on more load is applied to engine, resulting in minor loss of power. Totally normal.

[@anbessa21]

I accidentally removed the bolt on my hp line and now my a/c doesn't work. The freon got all of over my hands and I guess I inhaled it. I should be alright tho no?

[@ByRaff]

You still alive bro?

[@momofpower2488]

what should I do it my AC doesnt even turn on? What should I check?

[@06wrxdude]

Try bypassing that switch that I did in the video. That will narrow it down if it’s the compressor or if it’s a sensor issue

[@G00057747]

If your not getting lights at the controls, a fuse is probably out.
