Honda Cooling System Service/Fluid Change
HTML-код
- Опубликовано: 6 фев 2025
- In this video, I show you how I service the cooling system on a Honda. In this case I am doing a drain and fill on an 2.4L Accord. This procedure should be similar for 2008-2012 model 2.4L Accords and many other Honda models. The exact vehicle in the video is a 2012 Honda Accord Special Edition.
Some Honda models have a bolt to drain coolant from engine block, but many models do not, and the bolts usually require sealant or a new gasket if loosened/removed. The models with engine block drain bolts typically will drain about 1/3 gallon more coolant. There will still be be old coolant in the system no matter which setup the model has. I will typically do two drain and fills on the coolant system if I am concerned about getting all old coolant out (with a complete warm up and cool down period in between).
Loosening coolant drain block bolts on older vehicles that have never had them removed can sometimes lead to issues like leaks or stripped out bolts, so be mindful of that.
Honda coolant is long life, so if the vehicle has been properly maintained, one drain and fill from radiator every 60,000 miles or so is typically what I recommend.

If I changed the coolant and its leaking did I do it wrong?
@@cathym2311 If it wasn't leaking before it was worked on then most likely yes. I would double check my work. Also, a small amount of residual coolant will drip off for a little while after servicing it.
@ Big Dog50001 Automotive
It stopped leaking after a couple days. Thank you! Appreciate it. Good looking out!
Honda Type 2 coolant is colored red, as we saw on your video. Is this correct? Please confirm.
Your recommended seller links show twice more expensive than Honda dealers or other seller on Amazon
I am a college student and I have the same car. I don’t have money to pay mechanics. Thank you so much for making these videos on Honda’s. I really appreciate it
Glad it helped!
This work is super simple.
Just recently hanged my 07civic coolant. Less than a hour. No tools needed.
6ltr of Prestone coolant.
I'm a college graduate from1981 with the same car!
@@danr1920 💀you been in college for more than 20 years??
I'm watching this 6 years after it was made. This man is absolutely excellent at explaining the procedure! I wish some other videos were this good. I'll look forward to seeing his other videos.
Now this is a RUclips video why can’t more people be so informative like this man
I appreciate the comment, thanks!
The best demonstration of a coolant flagship on a Honda accord on RUclips PERIOD!!! Thank you!!!
Just wanted to say how great this video is. My automotives teacher has an entire lesson plan around this video, and it is by far the most simplistic/detailed guide he has shown by far. 10/10
Wow, thanks!
One of the best methods for changing the coolant in a Honda I've seen. I've always held off doing this because of the mess and spilling coolant as we have pets. The no spill funnel method is such a great help for doing it at home. Thank you for your down to earth videos without loud distracting music in the background!!
I put the distracting music at the beginning and the end lol. Thanks for the comment!
Dealer wants $125 to do this, but thanks to you I'm gonna do this myself. I bought the funnel and drain pan using your link, really appreciate the content you provide to help me service my 2012 Accord!
Thank you for the comment!
Some shop charge !165
I have been shuffling through these videos for hours and this has been one of the most helpful videos by far. Thank you so much for putting out great content.
Thanks for the comment 👍!
Just finished doing mine on an 06 Accord 2.4L EX AT! Had to replace the radiator and hoses and this video was invaluable. Even though I am familiar with the procedure, what made this tutorial all the more better were the tips, tricks, and nuances to watch out for. Thorough, concise, and clear - deeply grateful to you!
That spill free funnel is the BOMB! I use a vacuum system to fill my 600HP Cummins ISX, this essentially does the same in a much more affordable package. It really made the service on our 2012 Accord a walk in the park.
Saw lots of videos on how to do this and, by far this, was the most professional how to video. Thank you!
Just bought a pair of Honda's. 2011 Honda Accord with 65 k miles and 2007 Honda Pilot with 105k miles. Awesome video! Great job. I bought the spill free funnel and will now change the fluid in both vehicles. I paid about $20.50 a gal for the fluid from a dealership. Thanks again!!!
You bet 👍!
95 Civic DX - 1.5L - I replaced my radiator (definitely needed it), cooling fan assembly, cap, and upper and lower rad hoses.
The work went well but it appeared I had air in the system. Coolant was getting pushed out of the rad and into the overflow. I shut the
car down, let it cool, topped it off, drove home then clicked on your link and bought the Spill Free funnel.
It was very helpful.
I am still concerned that after 20 minutes I still had lots of bubbles but I will monitor things for a week or two.
I followed the video and changed the coolant in my 2014 CRV this afternoon and it works like a charm. Just heads up - do not remove the drain plug all the way out, or else some coolant will spill on the floor unless you have a huge pan.
Thanks for the comment!
On my Accord, Element, Fit, Civc and HR-V cars which have radiator caps, I can leave the cap open on the coolant reservoir/overflow and the cap closed on the radiator, which allows the reservoir to be sucked empty while draining. Then you can remove the empty reservoir for washing/rinsing much easier.
The Lisle radiator fill kit comes with different caps to fit the radiator which allows the cooling system to "burp" itself during warm-up. Very easy to do!
Right method is crucial for safeguarding against matter later
You saved me $130, thanks. I bought that no drip funnel too, very nice for pouring the old stuff into a gallon jug as well.
👍
What a down to earth video. Every step is explained perfectly and the available tools to do the job are well demonstrated.
I appreciate the comment, thank you!
Years ago Honda had a bleed bolt by thermostat. And they had a block drain plug. Good video.👍
Some still do.
Thank you once again for a easy to follow tutorial, I was here before when I had to change my power steering fluid for my 2010 Honda.
Just got my Lisle burping kit and two gallons of the Honda coolant. Should be a piece of cake. I will be super careful not to let it get hot. Thanks!
👍
Great vid, thank you. This was my first coolant change and I now have a lot more confidence. Got the same funnel system and squeezed top radiator hose before removing funnel also. Great tip. The coolant in my 2005 Honda LX was changed when car was cold, so I was able to touch lower radiator hose to verify when thermostat had opened up. Fans did not come on at this time, so the fans may not be only thing to use as indication of cooling cycle. It was also easy to watch the funnel from driver's seat and see bubbles start to rise up. During the second cooling cycle I saw the coolant level drop a bit in the funnel. Thanks again!
Glad it helped, thanks for the comment!
I was gonna spend the 140$ fir drain and fill and now I think I'm capable of doing it on my own, thx for the vid it helped out a lot. Thx for taking the time to post this. Made it look super easy
Thanks for the comment!
you said to turn the heat on - but in the video that you just turn the temperature knob to the hot side but you did not turn the Heat ON - could you please clarify - thank you
Thank you so much for posting this. finally a straight to the point no nonsense instructions. I had reservations doing this myself but now I have full confidence. 5 Stars

Good tip about the stubborn block plug. A wd-40 or similar overnight soak will protect against an stripping that aluminum block threaded hole. Patience is always key' in mechanics, dont get in a hurry and plan twice the time for the job until you get some experience.
Hi, my 2009 accord 4cyl sedan has greyish sludge in the coolant, any ideas what it could be?
jesus miranda sounds like a blown head gasket leaking oil into the coolant channels
Hello Big Dog. How do you think it will be better-Type2 or Honda Pro Coolant 1L 08CLAG016S1 (Japan) for the Civic 4D? Or is there no difference?
Good to see you can do this without having to jack up the car and crawling underneath to get to the radiator drain plug.
I have used the Lisle spill free funnel for quite some time and it works fine. However, I also have that Astro pressure test kit but just recently started using the vacuum fill tool. It took me a time or two of using it to get the procedure just right but I have found it significantly faster to do the vacuum fill. I can do an Odyssey with the dual heater cores and get heat from both immediately and no need for the numerous hot/cold cycles on the HVAC that the service manual calls for. The trick to the vacuum fill is getting the pick up hose all the way down into a bucket of coolant, before attaching to the tool, to make sure there's no air in the hose. The nice thing is the coolant goes into those hard to burp areas of the cooling system. Remove the tool, top off the radiator, put the cap on, run it for two fan cycles, test for good heat from the heater core(s,) top the radiator again, and ship it.
The Astro kit works well, thanks for the input!

This video was the best I’ve seen on here you really went into details, on what everything is, why you should do it, & what you should look out for great video!
I appreciate the comment, thanks!
I just found your channel last night, and subscribed right away. I have a 2012 Honda Crosstour (virtually the same car you have) and your videos are the absolute best. You really do an excellent job explaining every last step, and that will save me A LOT of money.
Thanks for the comment and welcome!
Thanks for the video. Recently purchased a 2010 Honda civic. No maintenance records. With your help, I'm sure I can do this myself.
This was an amazing video and it saved me a lot of money today. I did everything you said/did step by step and got great results after. Car runs better, no more overheating, and i used honda coolant. Thanks man! Not only did i do it myself, but i learned too!
Awesome, thanks for the comment 👍!
@@BigDog50001 You deserve it bud!👍🏻
Awesome level of instruction. Thank you for spending the time. This is my next DIY on my CRV. Really appreciate this.
Used your great video to successfully change the coolant on my car. Lots of help, thank you. The no spill funnel is the way to go.
Thank you for making this video. I have a CRV at 68K miles and will service the fluids myself along with all the other fluids. Small insurance premium to keep the car running well.
Thanks for the comment!
Did this coolant service on a 2011 CR-V today. All went as planned except for a few hiccups that always happen no matter how straightforward the repair.
The petcock was at such an angle, I couldn't get a good grip with neither my fingers nor pliers. It took about 20 mins to get all the old coolant out.
Lastly...I could never get the fans to come on. I did the rpm hold. Even waited for 30 min. When I turned the A/C on...both fans came on but stopped when the A/C was turned off.
One thing.... shouldn't we have turned the heat on before draining as to drain the heater core? Great video dave...and the tip about squeezing the hose before removing the Lisle was awesome and worked.
I appreciate the comment, thank you! I did mention in the video to move climate control to hot, to open up heater core. This is only actually necessary on older Hondas with a control valve to the heater core, newer Hondas do not have this and so it makes no difference if the climate control is moved to heat or not. I do not turn blower on because that can turn on cooling fans.
Very good demonstration to replace engine coolant with all kits & tools.
Thanks!
Great video and nice tips (like watching the temp gauge and squeezing the radiator hose before you plug the funnel). I have one of those funnels and they are great to have around. Thanks for all the effort you put into this video!
I appreciate the comment, thank you!
He is correct. Do not mix coolant types! Since we are on the topic of maintenance when changing power steering fluid purchase the HONDA power steering fluid from the dealer. I tried aftermarket approved power steering fluid "FOR HONDA OR ACURA" written on the bottles. The aftermarket fluid frothed in the reservoir and started making power steering pump noises soon after, not good. Changed to factory fluid for the right year of Honda Accord and no more frothing or noise.
Thanks for the input.
There's a big difference between those two.
Great video, very informative. And also the cleanest mechanic I've ever seen!
Best tutorial on Honda antifreeze drain and fill.
You have the best videos pertaining to Honda Service. Very professional and very knowledgeable. Thank you for the great info, keep the videos coming!!!
I appreciate the comment, thanks!
Exactly what I needed to do my coolant refresh since my maintenance minder said it's time. Thank you for the thorough explanations and precise, well lit work!
Many..many thanks for creating this video clip. Your step by step of procedure was very clear . In fact, it’ s help me for saving hundred bucks for my Honda Accord 2015 Lx coolant antifreeze change.
Thank you, I appreciate the comment!
Very comprehensive. Only thing I add is I apply a thin coat of silicone paste on the drain o ring to make it seal better and easier to remove next time.
Man, you are just an awesome PRO TY for all you have done to help us guys on a budget out!!
Thank you, I appreciate the comment!
Thank you so much for adding that info about the engine block drain bolt. My owner's manual is telling me to drain coolant from there, too. But I was hesitant to do that because that bolt has never been turned and I'm worried it won't end well. Based on your expert advice, I think I'll just drain from the radiator only. Then fill the coolant following your instructions in the video. Then do another drain and fill in a week or so. Would that be ok?
Love that funnel! Won't know what to do without it! Good instructional video Dave. keep it up!
The Disgruntled Mechanic Thanks Mike! I do have to admit it’s a pretty awesome tool!
That funnel is truly awesome! This way there is no mess.
upon seeing the condition of car, I have no hesitation to believe in you!
Great video. The no spill funnel was a great tool. Followed your video exactly but the fans never turned on for me. I know they work because when the AC is running I can hear them turn on. Temp gauge is staying steady right in the middle.
Each and every video of yours is perfectly done . In detail and U make it easy .Thank U my friend . Regards from NY .
I appreciate the comment, thanks!
Thanks man for the simple instructions, glad to know if it overheats first try to not freak out.
Great video; easy to understand. And I'm glad to see I'm not the only wipe-a-holic. Can't stand drips, puddles, or residue on my engine or accessories! 😄
Thanks for the video. I change my coolant the old fashioned way. I'm going to buy one of those funnel kits. It's much cleaner and easier than using a regular funnel.
Thank you for the comment! The spill free funnel really comes in handy.
Thank you so much. This is great information. I have three Hondas and I’m going to flush the collant each this weekend.
Thanks 👍!
Great video ! Clear and direct. Could you make a video in flushing the system? Thanks!
Great video. Lisle 24680 Spill-Free Funnel $21 in the US - $52 in Canada, what a rip.
C MH But that’s Canadian dollars right?? ;). Just joking, thanks for the comment!
thanks again, the part numbers on the Lisle spill free funnel and the Plews fluid pump were very helpful
Glad it helped, thanks for the comment!
Really good video, the best. I will let a mechanic do it this time. I will do it myself in 2030, if I'm still around. I will just do an oil and oil filter change tomorrow.
@@marksystemed4678 Thanks for the comment!
Wonderful video, one of the most helpful I have seen. I just did a flush along with a replacement of my radiator and all coolant hoses on my 99 Honda Accord. I had a slight rough idle so I am rechecking my work on bleeding the system. Thanks!
👍
Man I love your videos very detailed no filler and easy to follow instructions salute to you BigDog5001
I appreciate the comment, thank you!
Very well done. Thank you. he is really very methodical and hell of a mechanic.
I appreciate the comment, thanks!
I have never done this myself, you make it look so easy. Well next time screw the dealer, gonna do it myself. I have a 2009 Accord, 2013 Accord and a 2011 Ridgeline. Thanks brother.
Thanks for the comment!
Good overview plus his extra tips from an experienced mechanic...priceless info.
Thank you for the comment!
@@BigDog50001 thx again, I hope you r make it worth your while doing these RUclips videos. Working the camera and editing must be a pain in the a
I had the 2002 CR V coolant changed at the Dealer and we heard gurgling sounds for a long time until I think I realized there was air in the system. I saw an ad for a Subaru coolant flush and it was $189. Probably Honda has increased their price too.
Get that kit, I have owned one for awhile, they work and are much cheaper than going to the dealer. And they work on just about any car or truck.
Thanks Michael - I have the kit and have used it once on my 1998 Accord EX V6 and it was a big help. I need to take the time to do the 2002 CR V. I was surprised the Dealer didn’t get it right and left air in the system. Both Hondas are great cars after the junk I’d been driving and with proper maintenance and driving they just last and last.
Love how you keep it clean king
Thank you sir, simple and detailed.
I'll write again once I change my coolant on Civic 2012 1.8L.
👍
excellent video, thanks for taking the time to emphasize on the details while recording it
I appreciate the comment, thanks!
Thank you so much for your knowledge and showing us how to do things right not all of us know how to work in cars appreciate very much your knowledge thank you my friend...
Thank you, I appreciate the comment!
22mm 12 point socket works nicely on these drain plugs.
Great vid. How long does it typically take to cycle the coolant through the engine after refill or it’s sufficient enough to see the fans turn on twice?
Thank you for the video. After I did the flush and put the new coolant in, I let the car reach operating temperature and was running it at like 1,500-2000 rpm and the radiator fans didn’t turned on. Would that be a problem. If so what might the problem be? Thank you.
This is without a doubt the best and easy to follow video I’ve seen, so thank you! Just a question if you don’t mind. I have a 2014 Accord with only 45k miles. When do you think I should do my first coolant flush?
Another excellent video on a honda cooling system change
Thank you! Just did my 2010 accord using the funnel. Couldnt believe how easy this job was
Thanks for the comment!
I give it a three thumbs up 👍 👍👍 because no one explain on you tube anything but you did the other video I watch was muted or didn’t speak at all this video was very informative to me thanks I going to get that funnel at a cheaper cost ps I thought all anti freeze was the same I learn other wise again thank you sir
Thank you, I appreciate the comment!
Thank you for making this video, I will be using it to help me get the same job done tomorrow on my Honda civic. I gave you a thumbs up and subscribed 😊
Thanks and welcome!
Thank you Sir for this awesome and direct explanation on doing this, really appreciate your time.
Thank you for the comment!
The cooling fans don't come on unless using A/C or defrost. Temperature outside is cold not sure if that is the cause.
The vehicle may not be getting hot enough to turn on fans, very common in cold weather. Raising RPMs to about 2,500 for a bit can help.
@@BigDog50001 will do.
Thanks for video !
I did this with the radiator cap don’t have the tool and the fans never came on but it stop bubbling .
Also the car ran with heat on for like 25 minutes , so was the enough to get air out of system ?
This was an excellent video. You were very detailed I saw a couple others that took shortcuts and skin Dover certain aspects. Thank you
Thanks... I just changed my crv coolant. Next will be my Pilot and accord!!! 🔧🔩👊!!!
Thanks for the comment!
Big Dog50001 Automotive you're welcome and I just finished my accord and Pilot coolant changed 😁!
Thank you so much! Informative, easy to follow step by step guide. 🙏🏽🙏🏽
Glad it helped, thanks for the comment!
It dawned on me to use the C adapter with a B "radiator" cap and that tightens it up without excessive force. I only use Honda coolant and other fluids as they are well worth the cost to avoid problems.
Thanks for the input!
THANK YOU MR. HONDA SPECIALIST- MERRY CHRISTMAS AND HAPPY NEW YEAR
Same to you! I appreciate the comment, thanks!
Great video. My cooling fans never came on. I know they work because ac turns them on. I noticed a lot of bubbles. They stopped and after 45 minutes I turned it off. I might need to replace thermostat?
It is possible to have a bad thermostat or bad Engine Coolant Temperature (ECT) sensor (or fan switch), but not always, sometimes it can be difficult to get the engine warm enough to turn on the fans, especially if it was only idling. Usually I will bring the RPMs up to about 2,500 for a bit which helps and usually gets the fans to turn on. A scan tool can help in situations like this by showing what temp the engine computer is seeing on ECT1 (with a cheap code reader) or both ECT1 and ECT2 (with a scan tool that can read Honda specific info).
This was so helpful thank you! Your instructions were so clear and informative!
Dude i just put coolant in and then watched this video ughhh thanks!!! Very helpful
On my Daihatsu Skywing (Taiwan version of a Charade) I have found it necessary to disable the cooling fan and let the coolant boil into the (ordinary) funnel. Potentially damaging, but I think not as risky. as running the car with air in it.
I use two funnels stacked since the special funnel shown probably isn't available in Taiwn. Just got an Accord but dont yet know if my stacked funnels will fit it.
Excellent video ... so clear and detailed. I have to do this next week so your informational video is very valuable to me. Thank you.
Thanks for the comment!
How many km before changing coolant for Crv 17.sharing this video really helps a lot. Crv 17 has only one reservoir radiator fill all in one .how this process wokrs? Appreciated
The method you described about taking the rad cap off and setting it on the rad and waiting for the fan to come on after two cycles.....well after 25 min of the engine running and the coolant starting to steam but no fan ever came on......strange hope I did not damage my engine boy oh boy! Have any ideas anyone why the fan would not come on ...have a Acura Rsx which is made by honda??
Nice video. That Lisle funnel set is great. I’ve had one for years and it really does a great job.
👍
Thank you for doing this vid. I saw it on another channel, but its reassuring to see it on yours as I know you to be legit.
👍
Great video I'm in need of radiator repair plan to do it myself but where do I get the funnel you used
How often would you recommend to change the hoses? My 2012 is now 12 years old and the hoses haven't been changed and it's time to replace the fluid. Thanks.
Great video. I did followed your ticket all the way threw and been waiting for my fans to turn on. It’s been running for about 1hr and nothing. Car did reach regular temp and no overheating but fans never came on. Any advice pls thanks
My cooling fan does not come on at all unless the AC is on. Replaced the thermostat because of a code for bad thermostat. Thought maybe that would fix it. Could it be cooling temp sensor(s)?
Thanks again brother; great tutorial! Thanks for taking the time to film it!
I appreciate the comment, thank you!
