Service your Radiators Cooling System: Coolant Flush Honda Civic

[@jerimow8400]

Hey Dan! Thank you again for taking the time to make this video for those of us who need some help in these areas! I would be one of those people!

[@dannysdiygarage]

Thanks so much again, always appreciate hearing from you👍🏼

[@earthling1984]

Wow, that's much easier than I thought! I did the transmission drain and fill on my 8th gen after watching your video some months back. Dealership wanted $100 labor (I supply my own fluids / parts for jobs they do for me). They only charge me $20 labor for oil changes. But, I saw your video before I asked them. I knew it was as easy, or even easier, than an oil change. But because it has "transmission" in the name, they charge more. Now I am thinking of doing the coolant, it's been since around 120k miles, 5 years ago, now at around 165k. This seems almost as easy, just a simple drain and fill again. Anything extra I should make sure I think of or do?

[@vandiyplant921]

Thank you for sharing your knowledge and creating so many helpful videos. Learning a ton from all your efforts, thanks!

[@dannysdiygarage]

I really appreciate the super thanks $$, it helps out in many ways, I appreciate your kindness.

Love your videos!. I think the videos that you don’t have music on are a little easier to hear/understand you. This one the music Silas slightly loud, but other than that I appreciate you making these!

[@dannysdiygarage]

Appreciate your comment, I have deleted all music so people can hear what I’m saying, I have been thinking if going back and reworking older videos

[@ShiftyGearz]

Seems pretty simple. Something I've always neglected. Thanks.

[@kalani1987]

I would add that's it's important to bleed the system properly. I like to use a spill proof funnel and make sure the air bubbles are gone before driving the vehicle

[@dannysdiygarage]

Could you add a link to this for my subscribers

[@Kosar19]

I would say you are very smart. You should re-make this video. The original maker of this video could learn from you.

[@amill1563]

I've been using Water Wetter by Red Line as an additive.

[@johnr9907]

Great video. Just did mine however it was colder out. It's possible however it takes a lot more effort to get the fans to turn on. Mine turned on once and after that i let it idle for about 15 mins. Test drove it for 45 minutes driving agressively and everything worked fine.

Don’t u have to drain the block as well?? I used to do that on my 2008 Nissan titan??

[@dannysdiygarage]

If your cooling system is in bad shape do a flush, if you’re doing this for maintenance you can do a drain and fill

[@jondoh3471]

The music is distracting. Just keep it simple and straight to the point, which you're doing except the background music.

I was told when you are filling the radiator make sure the motor is running or the block can freeze.

How’s that happen? I’ve never heard that before.

[@stevedavis770]

I don't intend changing mine but have wondered where the reservoir is to check the level. Had to top up oil and had a look, found the cap in the place it is in this video. Most of the videos show a different system. Only had the car two and a half years 🙃

[@dannysdiygarage]

Glad it helped

[@vandiyplant921]

Hey Danny, would an opened container of coolant go bad? Checking because I know you said brake fluid does go bad and only used an unopened bottle. I have some coolant I used a few years ago to top off the coolant reservoirs wasn’t sure if it could be used now, always had cap on container when not used.

[@dannysdiygarage]

Your coolant is fine, brake fluid absorbs moisture from the air

[@gisot748]

Please, can you show how to clean the radiator? I have just replaced the AC condenser of my civic hybrid 2007, and I noticed that the radiator is all clogged with stuff. So, I would like to go back, take out the radiator, clean its outside with a moderately high pressure water jet, and put it back with new cooling liquid. My car has 235000 km.

[@johnr9907]

I wouldn't do that. You're better off replacing the radiator.

[@AubieClay]

Do you think I should change my transmission fluid or any other fluid besides the oil ?

[@dannysdiygarage]

Of course I do

[@migz2196]

Seen videos leave the radiator cap open after the coolant top up till the fans go on twice then close it after. Any thoughts about that Danny?

[@dannysdiygarage]

Yes if that works, in cold weather your vehicle might not get hot enough for the fans to come on.

[@edubb2491]

I use the lillly system on my 16 accord..its easyfill up till cant..turn car on with heater on high..then let it drink more colant..watch temp gauge..and done

[@thenaturalhuman9568]

Why do you need to replace the cap?

[@dannysdiygarage]

Great question, I should have clarified this, the Caps hold pressure in the radiator and keep coolant from boiling, if your cap isn’t holding pressure your vehicle coolant could get to hot, you can pressure test the cap to determine if it’s good, but the price of the tool is more than the cap

[@adanfranchi578]

Hi Dan, I have a 2018 Honda Civic 1.5T and I cannot locate the drain plug. Please advise? Thanks!!!!

[@dannysdiygarage]

sorry, I can't help you, could this radiator have been replaced with an aftermarket radiator with no drain plug?

[@MomentoMori769]

What does bad or old coolant look like? I haven't done mine it has 150kmiles

[@dannysdiygarage]

Coolant does wear out, They do sell coolant testers, that would be the best way, but if you have 150k it’s time to change it, color, smell and thing floating in coolant.

[@big2927]

I noticed on the front of my radiator there is a good amout of the fins folded over. Amazon sells large variations of tools to straiten fins. Do you have a certain one you can recommend please? Id like to do it without having to pull the radiator out, not sure yet if they'll be enough space yet.

[@dannysdiygarage]

I don't have a recommendation, good luck on cleaning up the fins, hopefully you notice a difference

[@angeloveniceflores8436]

Hello sir can i use any brands of coolant for my 2009 honda civic I just purchased valvoline anti freeze coolant.?

[@dannysdiygarage]

There’s a lot of brands that work, make sure it’s compatible with Honda.

[@iprophecy6768]

No you should. Only use Honda type 2 coolant. You buy it at any Honda dealer. Its only 21 dollars. 40 for 2 gallons. Dont cheap out. The factory coolant is type 2 coolant. By putting that valvoline garbage you potentially will ruin the engine. Only put type 2 coolant, or if you do put valvoline you need to drain the entire block. Which takes a ton of distilled water and hours to do

[@a.dejecacion9909]

Thanks for doing this tutorial video. Did you fill radiator until fluid got to the very top? Also, is it necessary to empty reservoir before refilling?

[@dannysdiygarage]

I did not go to the very top, leave some air burping room, once its all good, let it cool down, that's when you will fill it to the top, yes empty the reservoir

Thanks!@@dannysdiygarage

[@Oreosnacz]

Hi Danny, thanks for your video. Do I need to flush it out with distilled water if there is gunk, before I add the type 2 coolant?

[@dannysdiygarage]

Not usually, I don’t know what your cooling system looks like, but usually on these cars there fine, unless you have clumps of gunk in your radiator, you’re fine, if you do have gunk you probably have other issues

[@jacobashe6902]

How do you check the anti freeze coolant level?

[@dannysdiygarage]

check the coolant when the car is cold, remove the cap, and top off the radiator with Honda 50/50 mix, if it looks bad change it, otherwise top it off and add coolant in the coolant overflow bottle also don't over fill it, there is a full cold mark on the side of the bottle,

Hey Danny, I have a 2013 Honda Accord LX with the 2.4L engine and had a question about the coolant reservoir level. When my engine is cold and has sat overnight, the coolant in the reservoir reads exactly at the "min" line. After a drive and getting the engine fully warmed up, it is about 1/3 of the way between "min" and "max". Do you suggest I top off my coolant reservoir, or should I be good for now? Thanks for the help and keep the vids coming!

Hi Danny this coolant replacement went perfect on our civic 2010 and the heat blasts really hot on -30 windchill day I have a 2012 accord I had the dealer flush coolant at 90k, at 102k now and I notice the heater at max heat doesn’t blow as hot as the civic After dealer flushed accord it also made a weird sound in the dash area for a week or so when pulling up into the garage after a drive at the end of a drive The civic heat blows so that at max it hurts palm of hand Never gets quite that hot on the accord Could the dealer have done something incorrect when flushing coolant with their flush machine ? It’s been since spring 2022 when they did the work That dealer at 90k was first coolant service for accord I should have done it sooner and by drain and fill Ironically the civic was flushed by the same dealer years ago at 85k and I just followed your video’s steps to do a drain plus fill at 150k a week ago Civic always had hot air, accord gets warm just not the same degree as civic Both engines super warm after 20+ min hey driving

[@dannysdiygarage]

I doubt the dealer did anything wrong by flushing, use a scan tool and compare coolant temperature readings between both cars when they are at operating temperatures, also could be the blend actuator or door sticking, just a thought, it would need to be checked.

Coming from right side of the dash when pulling into garage to park , like inching up really slow/ creeping up slowly to garage wall That’s what I thought I heard pulling into driveway and parking after end of drive. I always turn off hvac at end of drive I noticed the coolant reserve tank went down after a week or so of driving and I topped it off. I plan to do a drain and fill when it warms up I am also going to replace the blower motor and transistor because a 4-5 years ago accord’s blower started making annoying mild buzzing sound, gets louder the higher fan speed.
