Honda Accord AC Evaporator And Expansion Valve Replacement (2003 - 2007)
HTML-код
- Опубликовано: 27 окт 2015
- Yes, this tiny little expansion valve requires you to tear into the dashboard to replace it. Blower motor and evaporator both have to come out before you can remove the valve.
Don't forget to recover the AC refrigerant before disconnecting any AC components and/or lines.
Applies to Honda Accord 2003 - 2007

This is the way a repair video should be done. Excellent video and commentary!
Agreed 👍
It's so good that you don't have to take off the whole dashboard to replace the evaporater in this car
Right
very high quality and rare video, it will help me when replacing my air conditioning evaporator, in my Honda accord 7, my evaporator is leaking, I will change it myself, as shown in your video, thank you very much for your work, good luck!
Superb video and excellent narration of what's being done. It's quite clear, that you are a professional. Most impressive was the use of a torque wrench to make sure bolts are tighten to factory specs. Thanks for posting.
my goodness, i can't stand dashboard vehicle work makes me frustrated just watching it. Great job man!
Best step by step video I've seen on RUclips. Subscribed after watching about to look through all his videos. Hands down best mechanics channel on RUclips! Thanks and keep doing what you do.
Nice video sir!
Clear views, solid advice and quality workmanship.
Great video. Thanks so much. I had no idea where they stuck that Evaporator, and I need to replace mine.
I have done a ton of these expansion valves. I have done them so much that I have proven many people wrong about this method of removal and replacement. I can do them from under the hood. Its all about the angle you pull it off and install it. The disk end of the valve has to be pulled out last and inserted first.
I forgot to say in the video that you must first recover the ac refrigerant that is in your car before disconnecting any of the lines / components. The car in the video had its refrigerant already recovered before the video was shot.
Now, that is the part of the video I was waiting to see but never saw.
@@daviderhahon 😆
If u had to explain that in the video then they should not be performing this anyways
What ac problems were you experiencing why did you have to do this.
so Mr wrench man favors us and you do for us a video for the new models like wish that requires the total dismantling of the dash board.Thank you.
Your videos are so precise and clear. Best I have viewed so far. Enjoy the Honda videos and hope you get back to me on the torch you used in the Honda engine video. Seems small and compact and manageable. Thanks again Artie
the torch he used is called the smith little torch. it's a torch typically used by jewelers.

Great video! It helped me not have to guess where all the screws were to take it apart. Thanks man! It was a very time consuming project though. It took me a few hours...
Well done, i was told by my instructor that instead of lubricating O-rings and gaskets with pag oil to use mineral oil instead.
Fantastic video! You make it look easier than it is.
"Let's put 8 tiny screws in places where no-one can find them for one small plastic cover".... I hate automotive engineers.
I used this video to replace the seals and expansion valve on my 2005 Acura TL. Being that they're sister vehicles, this worked great! Thanks man!
I'm trying to get the blower box out. I removed the 2 bottom bolts. And 2 on the left side. But it seems there in one more on the right. Maybe up top so where. Any ideas?
@@hmiinch7995 I'm about to do my 2006 Acura TL next weekend. Did you find the last one? Any other tings that were different than the video?
Awesome video, spot on. Did the job in less than half of what it called for. Thanks
Sir you were right on ....
Thanks So much ...
Took what I thought was a Big Deal , and made it Manageable.
Got Laid off Riffed during Covad 19.
This was a major Savings .
Thanks So much!!!!
Thank you for your time and effort with such good detailed video!!
Does videos just save me a 100 of dollars Thank you
Excellent directions. This really helped me .
Thank for you making this video. It did help a lot. You made it look too easy, although in my case I had an extremely hard time getting the cover off due to a clip it has at the top that connects to a tube right above the cover. I ended up cracking the cover but patched it up with some expoxy.
I did aswell due to mis information there are a total of 10 Philip screw instead of said 9 he said
I have a question: the air come out from the vacuum contaminate the ambient?
Thanks for sharing the TXV problem. My parts came from Rock Auto too. Think I'll get a factory TXV b4 I go through the time of experiencing it myself.
Excellent information. Thanks a lot for sharing your knowledge and taking time to make this video. I have a Hyundai Elantra and I would like to see how to replace the evaporator.
@8:15 - 8:30, I just did this and found it very useful to remove that temperature sensor before reinstalling the evap cover. It's very easy to do and can prevent accidental breakage of the sensor.
4cyl or v6?
@@donniev8181 V6
Thank you! You a life saver! Excellent video.
Great Video! Thanks for the simple explanation
This was a BIG help. Thank you
I wanted to mention that I had to redo this job because the aftermarket valve that we got from RockAuto did not work properly. It caused high pressure readings and the A/C had poor cooling performance. Installed an OEM Honda valve and the A/C is working great again. On the bright side - the job only took about 30 minutes this time around :)
What is the OEM Honda valve part #?
NVM. found it 80221-SDA-A01
happywrenching my mechanic is working on this except for her broke the screws somehow and I can’t find the part number on them. Where can I find them?
If you going to go through all the labor why not replace the evaporator. if it has any age at all the aluminum is bound to be degraded.
+NeilC Cross The evaporator is located inside a closed shell and in most modern cars a filter keeps it away from dust and contamination. It's not like a condenser, which is always open to road salt, dust and whatnot. Money for an evaporator, unless it leaks, of course, is better spent on a new condenser in my own opinion. I have a 15 years old car, with a 15 years old Harrison CVC compressor and ice cold air (as much as the blue type 42 PSI destroke valve allows), and while the condenser clearly shows its years with some bent fins and an opaque oxidated look, the evaporator looks shiny and clean and it seems new.
Thank u this was very helpful. I was about to put up my own video till I saw this.
Thank you for this video. Just did this. It is not an easy job but it would have been a lot worse without your video.
Hi, thank you very much for the video, I changed my AC compressor on Accord V6 2003, and since then Freon shoots out AC valve. I replaced the valves but it still doing that. Any idea? do you think replacing AC Evaporator And Expansion Valve would revolve it ?? thank you kindly.
Great video.
Please, how much quantity is PAG 46 oil does this car's compressor require?
Another reason for me to consider buying a 2007 as a daily driver.
This is one of the best videos on why you should buy a toyota. I'm in the middle of my daughter's Honda CR-V AC Compressor & Condenser replacement diy nightmare. I'm not touching this part, but very detailed video. Thank you. New subscriber too.
No, this is a great video on how to chop your car using a Dremmel, when you didn't need to.
@@Jez2008UKhow are you going to get the blower motor out then?
I have to do this in a 2005 Honda Civic LX...I’m already stress out...lol...thanks for the video
I really appreciate your video! It helps a lot 🙏🏻 thank you sooo much, definately subscribed after this video.
@happywrenching
What the size of the bolt that holds at the A/C lines to the expansion valve at the firewall ? Dumby me snapped the bolt in two :/
Exceptional video. Mine is fairly easy on a Saab 900NG. Except the tubes on the aftermarket evap don't match up to the lines in the engine bay. Is there a way to bend them? Would a propane torch help? Thanks!
Typical reaction - "OMG he cut the dashboard!!!" For the uninformed - that procedure is straight from the factory service manual. You have to remove that plastic piece by cutting along the sides. Blower motor will not come out unless you remove that plastic piece.
On my '06 Accord, I am getting low pressure on the High side (100), and about normal pressure on the Low side (40). I think the expansion valve might be stuck open. A shop checked for leaks and didn't find any, and they evacuated and recharged the system. But I am still getting very little cool air out of the vents. The compressor runs constantly, and I occasionally get some frosty air blowing out the vents, indicating that the evaporator is frosting over. The temperature of the line coming out of the compressor gets very hot (about 165F), but after the condensor it has cooled down to about 115F, so the condensor seems to be working alright. The low side and high side lines are not much different in temperature around the schrader valves - they're slightly cool to the touch but nowhere near cold.
So did you weld back the plastic?
Ha! Exactly what I was thinking. I understand now! Great video. I just wish it was more like my '91(which I can't find so far - just learning everything I can). Let me know if you do a '91 in the next week or so! (LOL)
happywrenching exactly!!! According to the service manual you have to remove that plastic, god job !!!!!!!
Remove the dash. Wow
Is it the same procedure for a 2012 accord
Hey I got a new AC unit for my 2005 Honda Accord and it doesn't work! Is there a relay switch I have to press or something? Anything helps!
I haven’t finished mine but i jus wanna say i love you
Interior work under the dash is my least favorite part of automotive work. 🥵 This video was top notch. 👌
How you got a head mounted camera up under the dash to film this impressive all by itself.
To other viewers, normally you have to spend a LOT more pain and suffering on this job by disassembling the entire dash. Props to HappyWrenching for figuring out a safe shortcut. (Pun intended) 🔧 🍻
where can you get service manuals with this many details?
what did you set the torque to on the expansion valve. thank you
Your videos are very good. You are very intelligent
profesional trabajó!! perfect !!
A huge Thank You for this video!! The step by step instructions were spot on. I wouldn't have been able to do this job without it!
i know im randomly asking but does anyone know a way to log back into an instagram account..?
I stupidly lost the login password. I appreciate any help you can offer me.
@Crosby Billy instablaster :)
@Jonas Colton I really appreciate your reply. I got to the site through google and I'm in the hacking process now.
Looks like it's gonna take quite some time so I will get back to you later with my results.
@Jonas Colton It worked and I now got access to my account again. I am so happy!
Thanks so much, you saved my account :D
@Crosby Billy Glad I could help xD
From Houston TX. Very thank you by this v/clip. It ‘s useful for everybody. 👍
Right on!
Very helpful. I was able to do this much better with the video.
Perfect explanation
Very clean job and superior master
I am going to attempt this repair ( I have a guy that will help recover the freon) but, I am not 100% on the symptoms. mine is blowing hot on drivers side and cold on passengers side. I put freon in it and it all works fine for a while....but then it makes a weird noise and a few times I could smell the actual freon bad through the vents, then back to hot on one side and cold on other - so everyone is saying expansion valve/ evaporator....not holding any suggestion as fact for this, just appreciate input. This is a GREAT video of how to do the job though!!
I got a 2004 Honda Accord that's doing the exact same thing hot on the driver side cold on the passenger side and the Freon blows out of the high pressure relief valve on the bottom of the compressor. I did some searching around and found out that there was most likely a clog in the system so I pulled the condenser out tonight and pulled off the little accumulator on the side and the thing was plugged up with these little white balls I don't know where they came from so I'm going to get a new condenser and accumulator and also change expansion valve
great video it will save tons of times to replace it, but 1 question does this work with lexus es300 1997-2001?
Excellent - thanks! Friend brought over his 07 Civic with no AC - checked fuses and relays and they were good. Only found pressure on the high side and then too much. How can I know if it's a clogged expansion valve/condenser and not the compressor? What's the real clue?
Thanks!
do you remember the readings in your ac gauges with the bad valve and with the new honda valve, and also the temperatures related?
normally when it goes bad the evap will frost over, frost on the line in the engine going to it...the evap sensor should shut off the compressor as a result but on some systems it won't
Save time by doing a quick fix, If your expansion valve is sticking and not cooling try this first, bled the freon first open the lines that go to the evaporator, high and low pressure lines from the firewall, engine compartment. Take a low pressure air line and blow out any restrictions in the line back and forth on both lines. Once you have done this take some break free lubricate and spray in both lines and blow with low pressure back and forth to make sure the lubricant has reach the expansion valve and let set over night. Next day blow out the break free lubricant once again blow out both lines back and forth until the break free lubricant has been removed. Reconnect lines and draw a vacuum and service the a/c with freon. WOW it works every time I done it and save you time and money! Note: Low pressure less than 30psi and not 120psi it could damage the evaporator.
I'd just replace the valve, the orifice inside it is very very small. I'd personally get a second hand evaporator, get the valve off of it and use compressed air (and an ice spray too) to just test the valve's correct operation and if it closes when you cool it down and opens when you warm it up, that's it...
This is how videos should be made, straigth to the point, save the bullshit for later. Great work my friend!
Two questions, 1, what do you plug the lines with to keep moisture out? 2, noticed torque wrench, what torque spec for valve? Thank you!
Hey I have a 2005 accord and started noticing a water rushing/dripping sound somewhere in the passenger lower dash area. I've checked the drains by the windshield and they drain fine. I have also pulled the carpet back and blown air and used a long zip tie to try and clear out the drain hose but nothing came running out. When the A/C is on it seems to drip normal so wondering where else I need to check. Could water build up in the blower and not leak onto the passenger carpet? Can water be trapped behind the firewall? Any advise would be great.
Good job!!! Thank you.
how did you find out the leak was with the expansion valve? dye wouldnt help as you would have to rip the dash to see the leak/dye ?
Very helpful video. Thanks!
Please, that green socket head shown, what is that for?
You're awesome man thank you for taking the time to do this video....I did it just like that on a 2005 Acura RL and it was a bit easier because I didn't have to slide the evaporator out, the pressure valve was just right behind the engine wall, behind the fan, plugged to the low pressure line going out... this video works perfect for RLs 05-09 I don't now about the newer versions... I am leaving the vacuum overnight to take all the crap out of the system and them purge and refill. I hope it was the valve the problem... I previously changed the compressor, it cooled for about 15min and nothing more there after....flushes it again and again and worked for 15 min and stopped every time... so lets see what happens now that I changed the valve... but.ones again thank you for this perfect video ma, really awesome👍
Cool, thanks for the info.
Thank you for sharing your video.best instructions I've seen so far....how long does it usually takes start to finish?
Not counting the time to recover and refill the refrigerant, around 2 hours.
what did you torque the expansion valve bolts down to?
just snug them tight
Can you please tell us which evaporator you used as replacement and where did you get the insulation you put around the expansion valve? Thanks
subscribed! amazing diy, u torqued the valve fasteners, yellow jacket gauges and you used suva virgin r134a
Does This Work for a 2006 Mitsubishi Eclipse ? (GS 2.4L 4cyl)
Absolutely excellent video, thanks so much.
Why did you do this for. I’ve got low pressure on both high and low sides
Hey great video,! If i changed all my ac components and flushed the lines. Can i just pour the required oil into the compressor . I drained the oil in the new compressor and added 9 oz.
Wow! What a cluster design! I hope my issue is just the compressor coil. A/C was working great until the clutch decided to take a dump. Thanks for the video, I’ll definitely use your instructions when I have to replace an XPV. Question, is there also a an XPV for the rear?
you can access the XPV behind lines at firewall
can i do same procedure to replace A/C evaporator in dodge caliber
What was the torque for the expansion valve
Is it an heater core temp sensor at 8:23?
The statement he mentions that he had to do replace his txv replacement because the rock auto valve he put in was bad. Thats whey after you replace a major component evacuate, recharge, and operate the system,(even without the blower fan) to verify the fix BEFORE you button up with all the screws. This guy did the opposite. Still a good job.
excellent video
I have a 2010 accord 4cyl , can you remove the expansion valve outside the engine compartment without taking all the evaporator out the car , it just remove the both lines connected to the expansion valve ?
Any tips on how to get the hose manifold to line up with the evaporator? I replaced all the hoses on my Accord and I'm having a really difficult time getting them to line up.
Informative video by the way, but I have couple of questions for you:
1) Does taking out the evaporator requires only dismantling the glove box part of dashboard for all cars? Or do certain cars need their entire dashboard removed to access the evaporator? One of an A/C shop that I know in my place remove the entire dashboard just to take out the evaporator which I dont feel good about it.
2) Does car A/C system needs a periodic maintenance? If it does, can you tell me what should be inspected and replaced during the maintenance?
Thanks!
No- all cars are not the same at all. Some cars require complete removal of the entire dash, center console and more. Terrible designs by engineers who have never worked on a car.
very nice! thank you
Great Vid!!! Would this be the same on a 2004 honda crv???
Is this the same process for the 2002 2.3 accord?
Can you tell me what low and high side pressures this Honda Accord should be showing ?
Excellent job
Good video but I have a problem ami if it gives me air but the hot air does not work me what will be the problem I have a honda accord ex 2005 v6
Understand to add pag oil to new evap core, but was that not the old one you remove from vehicle and added oil??
all i can say is thanks and it was awsome to watch..
Glad someone is still finding it useful!
Is this the same for both the V6 & I4?
where did you get the plugs you used to plug up the refrigerant lines while you were replacing the expansion valve? Thanks
I had the plugs laying around - they were from other A/C parts that I've bought in the past. No clue where to buy them on their own though.
Thank you so much for taking the time and making this video. Do you think that this is what I can expect for a 2007 Acura Tsx? Thanks again for all your efforts in helping the average diy'er take on these kind of projects.
+Fernando Romero Everything that I have seen online shows that the process is similar for that car.
+happywrenching Thanks. It is actually a 2008. Hope it's the same. Starting the process now with your video qued up. Thanks again
Would this also apply to an Acura TL form 2004-08?
That's a lot of work. I need to get something to cut thru that plastic now.
What will happen if you skip the last step of removing the moisture and air? Since I don't have that either
I wish this worked on a 2004 model. It has a slightly different connection at the expansion valve and I have forgotten what holds it on. It has a rubber grommet on the outside and you have 2, 10mm nuts that hold a plate that is holding the lines in place. It helps to remove that plate and pull the rubber grommet out so the lines are free!
Very cool, thanks for teaching people, I noticed that you weighed refrigerant @1:32 -1:35 , What is the weight of the car's refrigerant gas?
great job
In the video at 2:20 the cable you said you couldn't get out so you broke the retainer... just take a small socket (I used a 1/4") and seat it over the top of the white plastic retainer on the wire harness. That will squeeze the tabs that keep it attached and allow you to pull it out of the hole without breaking it.
