Replacing the Evaporator Expansion Valve Honda Civic

[@rbilardo47]

Hi Dan, you're probably tired of hearing from me, but I have great news. Last night after I finished charging the system I could only get 60 degrees from vents, so that's when I replied to you. Now, the next day, I started the car and the A/C, and to my surprise 40 degree cold air was flowing from my vents, so my wife and I took a drive and it remained 40 degrees and it's about 90 degrees outside here in Florida. So it was the expansion valve all along. Crazy, but thank God it's working fine now. I ordered a compressor this morning before I started the vehicle, and I just cancelled the order, not needed. Dan, I can't thank you enough, I would never have been able to do this job without you and your videos. God Bless you and your family.

Question what were your symptoms if I may ask? Im along the lined thinking compressor vs this expansion valve. Did swapping resolve your issues

Dan is the man! I had an ac clutch problem, replaced it with an Amazon kit. Two days later, the electromagnet started smelling like ozone, blew the fuse and quit. Got a replacement kit, didn’t know the fuse was blown, and spent four hours backwards troubleshooting it to find the ac clutch fuse had blown. Kick me, I’m stupid sometimes!

@ 21:30 Evaporator was extracted. I think if the words "Evaporator Replacement" would be included in the title of the film, it would get way more viewers, since there are very few films on the subject. The project is generally considered to be complex and many interested in it would love to see this film. I personally pull it since wanted to see, out of curiosity where the Expansion Valve is located on Honda, but then to my surprise I saw and Evaporator to be extracted. Very glad I did it, I also plan to update everything in one of our cars (2001 Saturn SL2). @ 26:58 In the Shop Manual for one of our cars it says to put R-12 (mineral) Oil on the o-rings, when you install a Condenser (on corresponding hoses, which go into the Condenser). And they add: don't put PAG Oil (which is in the AC system there, runs on R-134a refrigerant), bcs of possible corrosion issues in the future. Though when I did research about the install many advised w/PAG Oil on those o-rings. I'm not sure if any oil should go on the o-rings in Expansion Valve. Thank you very much for such informative film.

[@GregsYouTube]

Yes my thoughts exactly on video title which also should include car model year and I'd think pag oil would be needed on orings

Dang, the patience required to do those hidden bolts/nuts/screws--drives me nuts on this car...I spent an hour the other day pushing on a crowbar with one hand, holding a bolt in another hand, and a socket wrench (in another hand? angels helping?) just getting the one deep bolt back in under the passenger headlight assembly for a simple bulb change (after of course climbing under car and taking off bumper...and before climbing back under car to put bumper back on...crazy!)...what you did getting down in back of engine and not dropping bolts and then flat against floor into deep hidden hole for bolts, only to have to go even more ninja to grab that last hidden screw...if I'm patient I think I can take it apart, but back together again? don't know if I have it in me -- certainly I'm going to need new tools to even try (isn't that really why we DIY? to tell wife it's cheaper to buy all the tools than to pay mechanic?)...is there such a thing as magnetic flexy sockets?

This worked for a 2016 Honda CRV EX AWD. I pulled the center console, radio and climate control panel. I also removed some dash screws on the passenger side including the glove box support bar and I was able to sneak the blower motor assembly under the dash while bending up the dash. So I did not need to cut the lower dash section. Thank you for your demonstration.

As others have mentioned, its possible to pull out the expansion valve from the firewall side and avoid this whole disassembly. It requires some 90deg needle nose pliers and picks. You may have to very gently shave part of the opening with a dremel. Keep everything clea. Still, FAR easier than this method.

Such an amazing video. Loved watching it. I have a hissing noise coming from my passenger side AC vents and it’s intermittent and only when I hit the gas pedals and car is in motion. Could this be an expansion valve issue or just low on gas. It’s a brand new car and dealer says this is normal but it’s annoying.

[@ParallaxVisuals]

the hissing means you’re out of refrigerant

[@johnmcdonald3231]

How did you diagnose that’s you had a bad expansion valve?

[@rmmanning4u2b]

Maybe there were others who made this same comment and their comments were deleted somehow. I was surprised that you didn't mention evacuating the system of freon as the first step (either with your own system or taking it to a shop to reclaim). Then, I discovered later in the video that you obviously hadn't done that step and just let the system depressurize into the air. While modern R134a freon is not as destructive to the atmosphere as R12 was, there are still laws on the books that make this practice illegal. This video is encouraging people to unknowingly break the environmental law in the US. Maybe put some disclaimer to tell folks to start out evacuating the system of freon first?

[@dannysdiygarage]

That’s a great point, hopefully people do the right thing, some shops will actually do this for free, others will charge up to $100, I know this because I researched it and was surprised of the cost, I believe this was mentioned in one of the other AC videos I did, once again Great point 👍🏼

I eliminated everything else, I need to do this on my other Civic also, these expansion valve plug over time Low evaporator (suction) pressure; High evaporator and compressor superheats; Low compressor amp draw; Short-cycling on the low-pressure control; Somewhat high discharge temperature; Low condensing (head) pressure; Low condenser split; and.

Hi Danny, I have a 2008 honda civic. Just had system recovered and recharged because the inside air was not cold. Still not good. A/C low pressure reads 40 psi and kicks on compressor, pressure then goes to 30-35 psi and kicks off. High pressure side is 190 psi. Cabin airflow is 60 degees. Before I tackle this job I would love your imput. Is my expansion valve in need of replacement. You didn't explain how you knew is was bad (unless I missed it somewhere, lol). Anxiously awaiting you answer. Thank you. Best videos on the subject, very efficient.

How does it blow when you’re driving down the road, on the highway

[@dannysdiygarage]

Make sure your fans are working properly and both are on, make sure the blend door is working, the blend door opens or closes off the heater core air, this is accessible under the Driver R side dash, you can't miss it, turn the knob from cold to hot and you can see it moving, make sure its completely shutting off and not sticking, there is also diagnostics, turn the key off - then hold down the recirculation button and rear defogger button, then turn the ignition with on, the blower will run on various speeds if no codes the recirculation button will not blink. if all is okay, an expansion valve could be the issue, however with out being there I can only make a educated guess, please update this channel to help other once it's fixed, thanks so much

@@dannysdiygarage I started removing everything last night. I have everything removed except I don't have a screwdriver long enough to remove that one screw. I'm going to lowes to pick on up. I will update when I finish this job. thank you so much.

[@rbilardo47]

@@dannysdiygarage Update Dan. I finished today, job went well, no leaks, vacuumed system and recharged it. I can only get 60 degrees out of my vents, but it is a lot better than it was prior to this installation. I have no idea what is causing this, compressor runs good, both fans operating as they should. I'm stumped.

[@dannysdiygarage]

Did you check the blend door,

[@privatename3621]

Hmm. I see at 4:00 that after you pull off the AC lines that are connected the expansion value, you go through a lot of effort to remove the blower motor assembly and evaporator core on the inside of the car (and even cutting the dash molding. But in another video (kzbin.info/www/bejne/pHSql5iwdryijZo) I saw that the guy just unscrewed he expansion valve and removed it from the same area where the lines were removed, which is probably how Honda was expecting people to do it. Just unscrewing and wiggling out the expansion value, replacing o-rings, and pushing back in the new one with screws. Just thought I'd pass this along as another option for other people watching this.

[@dannysdiygarage]

Appreciate the feedback, I went by the factory manual, I’m not convinced this is possible on this year, are you going to replace your expansion valve this way? If so please update me on this channel and let me know how it works, this will be a huge time saver if it does, the disadvantage would be you would not be able to inspect the evaporator for leaks, I own two Civics, maybe I’ll give it a try and see if it’s worth it, thanks for this additional information

[@pasivo2009]

I think that the valve can be removed from the front to avoid the mess that has to be done inside.

[@dannysdiygarage]

Good luck, let me know if that works out

[@pasivo2009]

another question. How do you get refrigerant 134 out of the system? with the same autozone vacuum? in that step I get complicated

[@dannysdiygarage]

@@pasivo2009 some shops will remove it for free, they do this so you won't release it into the air also it valuable to them because they can reuse it.

[@thefelixpinon]

Great video 👍🏻

[@dannysdiygarage]

Thanks so much

[@helpfulhippo3744]

My very first step is to remove the lines at the evaporator .... What about recovering the refrigerant ? I'd hope nobody followed this verbatim and dumped a fully charged system spraying themselves with refrigerant oil and supposedly damaging the environment.

[@dannysdiygarage]

I hope so also

You removed ac hoses but forgot to mention that you had already extracted the R134a. If someone with half-assed knowledge tried to use your method, they will spray themselves with extremely dangerous CFC probably disabling themselves permanently. I can't believe no one pointed this out.

I'd buy a new car before going thru that process, I see trying to put too much in a little space with a part that might have to be changed a few times during the life of the vehicle. A throw away purchase with a hefty price.

There’s a right way and a hack way

[@VicenteTorres-j5q]

1 you did not flush evaporator 2 did not use refrigerant oil to lubricate O rings before putting expansion valve.

[@dannysdiygarage]

Correct, I did not flush the evaporator, I did not have a catastrophic component failure so it wasn’t necessary, I used the oil that was already dripping out of the evaporator to lube the orings, update everything is still working great , appreciate your feedback and you watching this video 👍🏼

[@Alex-ti3uf]

Rule of thumb, if you are replacing the expansion valve, you must as well replace the evaporator since you removing to get into the expansion valve.

[@dannysdiygarage]

I haven’t seen that written anywhere, depending on your budget, my budget is small, thanks for sharing your thoughts

[@Hellkid13]

Unless that hole was just way too small it looked like you could have removed it from under the hood

I've would be curious to see if that works, I doubt it though

what a fuggin nightmare bru

Why are you doing this?

AC wasn’t blowing cold and the proper amount of Freon was in the vehicle,

This job can all be done from under the hood. No cutting your car up with a hacksaw blade.

No, this is the easiest and least destructive way, the piece that was cut, serves no purpose, do it the way I showed you, it’s easier then it looks

[@davidwalker7383]

@@dannysdiygarage You CAN do this job with out all of those extra steps. All under the hood.

[@JoelIvoryJohnson]

In the absence of any supportive evidence for this claim I think this is misinformation. I just examined the way the TEV is against the firewall, it is wider than the hole. It cannot be pulled forward through the hole. The manipulations necessary to work it through the hole in the firewall are constrained by the evaporative core’s tubes being within the TEV. I had my car’s AC in pieces and examined this claim myself. See the video short at the link below. Saw off the piece and remove the interior components. Remember to replace the O-rings while you are at it. kzbin.infolq4rEBP-1Kw?feature=share

[@tonyjordan1320]

I just watched this video and besides taking all this apart-keeping up with which screws/bolts go where then to put it all back together again looks pretty challenging. How do you get the expansion valve out thru the firewall so you can swap it out???
