In the service manual for my 1999 Acura Integra, it recommends replacing the engine coolant every 45,000 miles. Before getting started, the first thing you want to do is make sure your temperature control is on maximum heat. For modern cars this is often an electronic control, so you may need to run the car or at least turn the ignition on beforehand to make sure the heater core is opened up. This will ensure that you replace all of the coolant in your car. Before working on the car in any way, it’s critical that the engine and radiator have completely cooled down - you’ll often see a warning for this on the radiator cap. This video will walk through the process of replacing the fluid.

I think it is cool that you used to design these systems and now you are working on them and giving the public the information they need to properly service them.
I've probably watched 20 videos on coolant flush, looking for someone to explain where to find the engine block drain bolt. I know my car is not the same, but now I have a reference what it may look like. Thanks!
Let me know if you find one.
If you live in a cold climate, it can be worth flushing the heater core separately. My old car would give absolutely no heat in the winter; but after a back flush of the heater core not only did the heater start working significantly faster; it put out heat like it was brand new. This can even help with reducing how much time you let your car idle/defrost before leaving.
As an ex motorcycle rider I love the car heater and I'm in Australia.
This is awesome advice! 👍🏽👍🏽
Great video. Proper maintenance is very important and often overlooked by many people. Money spent early to prevent failure is cheaper than money spent later for a repair. A good recommendation is to also fully flush the system with water and use a coolant tester to ensure a proper coolant to water ratio after refilling. When bleeding air from the system it is good to have the part of the car where the coolant filler point is to be elevated to assist in removing air. Like the video says a half is not an unreasonable amount of time to wait. An air pocket could cause a sudden unwanted rise in temperature causing engine damage, especially if the head and block are of dissimilar metals, or completely aluminum.
The video was very easy to follow. I am going to try this for the first time, on my own... tired of paying outrageous prices for a 10 year old car! This looks easy.
Ina Spivey same. I will as well.
that coolunt looks delicious, the ideal sports rehydration my golf coach says.
Rich in potassium
Rich in antioxidants... or is it antifreeze?
Apple juice with no added sugar, anyone ?
John Kyon your Volkswagen Golf coach says?
The drained coolant liquid is Mountain Dew.
The engine drain bolt is what most people skip. Great job!
Some cars have bleeder screws to help purge the cooling system. The GM 3100's have one on either side on the front of the engine. Open the one on the accessory belt side until air starts escaping then when coolant starts squirting out tighten it back up.
Always good to measure the amount of fluid that you drain so when you fill it you know what your shooting for. The thing I would worry about in this video is you drained the engine block (nice that it has a bolt for that which is easily accessible) so when you refilled (thermostat closed) did the block get enough coolant mixture for a safe startup. Knowing you drained a gallon and that you put about a gallon back helps to give you confidence that it did. Just an extra bit of knowledge. Great video. Thanks
@@168grhp - you can’t generically say that the system will automatically purge the air. This is absolutely wrong in many cars like some Toyotas
@@condor5635 I deleted my comment to keep from misleading someone with a cooling system such as you describe.
A trick I've found helpful for bleeding some cooling systems is to get an old/cheap radiator cap that fits,and pull the valve part out of it,so it's just the cap. Install said 'gutted cap' and drive around a bit,while keeping an eye on the temp gauge. Park it,and let it cool,and maybe repeat,if needed. Then install the normal radiator cap. This way the air will bubble out into the overflow tank,and when it cools,it will draw coolant into the radiator from the overflow tank. Self-bleeding. It just takes a couple drive cycles.
1:34 probably should mention that the reservoir is not easy to remove in a lot of cars.
The magic of video editing... 😂
How do you know when the air is out though?
The easiest way to feel confident about it is to just wait 30 min?
Great video by the way. Its informative on something that in not technical but quite handy.
When you stop seeing bubbles gurgle up from within the fluid.
Why are air bubbles bad?! Can it cause problems if you don't get them all
@@ninjalobo7 Basically if there is too much air, then it wont cool the engine as efficiently. The coolant mixture transfers heat much better than air. So it might overheat with too much air, but some is fine.
Its practically impossible to completely get it out.
I don't use coolant in my Accents, it's just another one of my weight reduction mods
cool you saved 3 kgs in your car
Accents are naturally cool.
Hotter engines run better you know
Henry Rasia too hot and you are fucked
😎 If the car's paint is blue, it keeps the engine cool.
Awesome video (as always). In a future DYI video, you might spend just a few seconds explaining the torque wrench -- both why it's important, and how it works. It's probably the only part of this process that would be unfamiliar to most car owners.
I agree. I have no clue about torque wrench
As a general tip I always attempt to get as much coolant into the radiator as I can before starting the car. Squeezing the hoses will help. Most cars also have bleed screws which must be used both before and after starting the engine.
What’s the idea about getting the air out? How do I do that when using a regular funnel?
@@ktfoent for example if the top hose is full of coolant then the radiator will be full. What one is trying to avoid is having a system that needs filling the next day or worse, driving on a partially filled system may blow a headgasket. Vacuum filling works the best particularly on rear or mid engined cars.
Thanks for making a sponsored video that isn't super hacky. I don't mind when it's done right.
it amazes me how useful your videos are even that much time after.
The plastic drain valve on the radiator can easily break on older cars and leave you with a bigger issue. It may be better to remove the lower rad hose to drain the radiator.
Finally someone that knows that sitting in the paint does scratch it and therefore used a rag to protect it.
Great video, I like these do it yourself videos, save us time, money and we learn something, and how to maintenance our vehicles.
Try to avoid having spilled or open coolant around pets. it smells sweet so they are often attracted to it and its extremely lethal. so clean up any spills after :) great tutorial
One of the many reasons why it's embittered.
you dont say
Dang. I just love spilling chemicals around my dog and letting him lick it up
2:16 Thanks for that info. I drained, flushed, and filled my 06 Scion XB and was freaking out when 20 minutes later the fans wouldn't turn on. The coolant was starting to steam and I was about to turn it off when the fans kicked and more air came on
Love these car maintenance how to videos, keep up the great work!
This was so easy and to the point. Thank you!!!
the one thing i might add is to place the front of the car either on jacks or on an incline to help with the purge, the other is to squeeze the top of the radiator hoses to help move the air through the hoses
Impressive advice and damn you got experience on vehicles as 1 advice on here you mentioned many won't even know! So hat off to ya.
I've been anticipating this video. coincidentally my radiator developed a small crack yesterday.
Ha! Thank you for posting this video. My local garage wanted to charge me $270 + tax for the job.
Lisle spill free funnel is a must and it's cheap. I know this is a sponsored video but for Honda's get the OEM Type II blue, you can mix it with the older green stuff if that's already in the car.
I've watched several of these and yours is very informative very step-by-step very easy for the novice I do know a little bit about cars because my father taught me I've even helped pull engines but I have not done my own for awhile so thank you
Excellent video, no kidding around, straight to the point.
Do all engines have drain bolts? Ive never heard of them until this video. And would it be a bad idea to run distilled water through it to flush out the coolant in the engine, then mix the 50/50?
I was wondering the same thing!
Easy yet important. Awesome DIY . Screw reviews - DIY's would reach way more interest in my opinion.
you should park your car uphill to help the air escape faster since your cooling system is an open system (it has a radiator cap). for closed systems park downhill and remove air from bleed nozzle near the heater.
alot of cars have a bleed screw on the thermostat, surprised you didnt mention that
Bro you are the best. I just did this and saved myself some money.
Thank you for your Video. It's very clear demonstrated. Awesome.
it would be cool if you could do a video on how to adjust windshield wiper arms and blades.
Another one that forgets OAT coolant must not be mixed with ethylene glycol (unless stated as compatible).
OAT antifreeze generally called DEX COOL.
Mixing generally causes gelling.
Some modern BMWs have an electric coolant pump and there's a special bleed procedure to get all of the air out:
Fill the system with coolant
Hook up a battery charger if possible
Turn the ignition on, temp to max and blower to min
Press and hold the gas pedal to the floor for 10s
The system will then run the pump for about 10-12 minutes and bleed the air out of the system
modern bmw suck
wow chrisfix got old 😅
looool, I got that :3
?
+Taylor F. I'm assuming zibby is referring to another YouTuner names ChrisFX who does DIY maintenance on car videos and he does a coolant flush tutorial much like Engineering Explained I'm assuming
+2PacPRNDL RUclipsr named*
2PacPRNDL I know of chris, but his change was full out flush, this was just a change.
Normally I'd be cynical about sponsorships, but AutoZone is a good shop! Every time you stop in there you leave happy, the people there are usually knowledgable enough to point you in the right direction and they don't upsell you all that bad. Sometimes AutoZone saves your ass, thanks guys!
Thanks for sharing this video.🙏
I have a Honda Civic 2009 and want to flush the old coolant completely since I'm not sure when it was changed by the previous owner.
Q: You drained the engine block and started the car without coolant in the engine block. Does it DAMAGE the engine? How it should be?
Q2: How to ensure the heating radiator has drained (starting the car may needed)?
I did not know you could rent tools at auto zone that's cool
yeah i think also chrisfix got old, he didn't show on his videos how to drain the coolant from engine block. this video is good one.
now thats a nice integra
I need help changing my blinker fluid and exhaust bearings
And piston return springs,dont forget about that its very important
dude...u r superb and I really love ur work..I've learnt a lot from ur videos and thank you for dat...aaa...well, I want u to make a video explaining all the types of chasis and their work...I mean all about chasis...hoping to see this upload...
I wish the best of luck to anyone actually attempting to follow these instructions. The engine block drain bolt is completely inaccessible in my 2010 Nissan Rogue, so that part of this video cannot be completed for me.
Thabks, A Great Video for us DIY’ers who have to learn and maintain a car during hard times(increased cost of living).. As a complete car repair novice, my issue is the mix, do you buy it already mixed or do you have to mix it with distilled water..? Thanks in advance..
This video quality is mint !
You sound like Kirk from Gilmore Girls-I love it! Thanks for the info, friend!!
I just open the cap and refilled. That was a mistake 😂
Why?
Its bad to just top it up ??
@@betsthatnguyen It's fine to top up. Just make sure you only use distilled water/coolant. But changing the fluid (draining everything) is recommended every 5-10 years. And if you need to top it up, then you have coolant leak. It's a sealed system, you should NOT be losing coolant. Find it before it gets worse and leaves you stranded (or orverheats the car).
Sweet.. going to the garage to do this on my wj grand Cherokee thanks very helpful!
Awesome, good luck! :)
why can't the system purge air into the reservoir tank?
Good to see the integra is still in the fleet? Are you Club Integra sir?
in some cases may need to find a bleed valve or put the cap back on when running to create a vacuum
Bleeding is typically for the engine block's cooling loop. Bleeding would be unnecessary if the thermostat opens completely as the system _should_ be designed to force any air to go to the radiator. Although, some cars really do need to have it bled as you suggest. So, as always, check your service manual. ;)
I never pull the drain plug.. Yikes never thought this was so specific.
Just flush it with water a few times although the coolant in this video looked ok.
Neither do I. I save a shitload of time by dumping it all at once from the lower radiator hose.
The autozone closest to me is full of idiots who almost sold me the wrong coolant for my mustang, i forgot to check the kind i should use before going to the store and relied on their knowledge and plentiful resources to tell me the right kind and they failed to do that. All that aside i enjoyed the video keep it up.
On some newer cars that have the end tanks on the sides of the radiator instead of the top and bottom, there are air bleeds located on the engine block that need to be opened for the block to be purged of air trapped in the engine or over engine heating with disastrous results.
The feels when your car doesn't have a radiator drain... I have to take the lower rad hose off every time lol
That's easier and better anyway. Those damn plastic pepcocks like to break off after they're 5 years old and don't drain as much fluid.
Mine has a metal tap. Best of both worlds.
Trying to find the radiator cap on a European car is like digging for gold. You need a tool kit and map
What better way to start your day by drinking a glass of lime cold green coolant 🍸
Thanks for making this video. You saved me some money by not having my mechanic do this easy task.
Can you do a video on CVT?
Could you do a video on how to change the head gasket on that sort of car? or something similar of a head gasket how to?

Remember to drink at least a bottle if you go to Canada in winter ;)
Easy and straightforward!
a great fan of yours. your videos help explain alot. I live in the pnw also. my request is, can you do a video about tire compound and tire treads especially since we live in 4 seasons?
couple of questions. 1. how can you tell when all the air is purged from the system? 2. can you do a video with all the mods you've done on the integra at once and compare it to stock, to see how much of an impact they have when combined with each other as opposed to just individually? also I love your videos. I feel as if I learned a lot form them especially since I started watching your channel when I started taking auto in high school. it was extremely helpful to see one of your videos and then be able to talk to my teacher about them so I could use your videos to see the technical science behind some then and then my teacher could explain more of a real world application of it. keep up the good work
"When you see no Bubbles you're good to go"
I have a 1974 plymouth satellite would it be almost the same process?
Thanks buddy. Your video was very helpful
Sweet we both own an integra. Mine is a GSR
Thank you I’m going to change mine soon
Hello... That was easy enough to follow. Do you have to drain the water from the coolant tank before you go get an oil change????
No theyre separate system and don't mix. 🙂
Unfortunately none of that applies to a 90s or 2k VW, inasmuch that there's no rad cap, no rad drain, no engine drain plug and no heater core valve. Plus the thermostat should be removed for a complete flush which is easiest done by flipping the car on its roof. In addition you'll need vw specific coolant which inexplicably changes from year to year and costs several orders of magnitude more than conventional coolant.
And yet the early 2k Audis have drains for everything, also the coolant does not change year to year, old cars g12 or 13 works just fine.
The Earth Is Cubed how to drain coolant in 2010 tohoe
you can just modify a radiator by just welding on a drain plug on the bottom of it.. stop bitchin and get creative.
is it possible to fill the radiator with urine if yoj don't have access to water, for example, in the desert, ?
Spit in it.
doubt you would produce enough and it would corrode the system because urine is acidic.
although in ww2 British troops would fill the water jackets of their machine guns with urine because water was better used for hydration than keeping their gun cool in the desert.
thats nasty
+John Kyon lmao
Technically, yes. If you could produce enough urine without access to water, it would work.
Love your videos mate. Huge thumbs up!
I own a 2015 VW e-golf and am curious as to what things I will need to do differently since this is a fully electric vehicle. I’m at the 66k mile mark and this is one of the service items I need to check off
Thanks for your information and it is of great help for me bless you my friend.
what kind of engineer are you? and what degree do you have in order to be in your position. I am starting college and I am looking into your exact field. thankyou
do a video explaining different types of coolant
So this is just replacing the coolant and doesn't include flushing the system...?
And remember that Mountain Dew is a safer alternative to coolant
Big big help. Thank u.
Good explanation superb brother
Thanks Sir
Awesome explanation !
Might want to add a disclaimer saying how toxic the stuff is and how much animals like the way it taste. Good video though.
Taylor, don't taste it then. Bad human! BAD!
Btw its antidote is vodka 😅
Kids too. They sure do like themselves some coolant.
@@irresponsiblyblue1411 So that you'll give them alcohol 😂
@@muratdogusan Not antidote you braindead dumbass. It's a competitive inhibitor which means it only works if your blood levels of the ethylene glycol metabolite, oxalic acid, hasn't reached toxic levels
Wouldnt thread seal stop you from opening the drain plug next time?
Nope, it simply helps prevent it from leaking. Recommended in the OE service manual.
You're thinking of thread locker, not thread seal.
Can you do an article about Evans Waterless Coolant? Does it really work? Thanks
Thanks
This does not apply to all cars, for example some BMWs will overheat and kill the engine if people try to change coolant with these instructions.
My E36 can be done just like this.
How so?
So basically read the owners manual
Hi, that was really helpful. I have a query. After riding around 2500 kms on my new motorcycle, I noticed my reservoir level was just below the low mark. But the radiator was full. Is it okay? Thanks in advance
The reservoir is also known as the overflow tank. The reservoir can be low with a full radiator. It just means that the radiator needed more coolant and it drew from the reservoir.
I would say even for something simple, refer to the owners manual or a forum for each different make. My Nissan for example, Haynes did a how to and they don't mention draining anything but the radiator, just saying.
Very informative. LIKED....SUBSCRIBED!!!
What if coolant is filled more than its max level in reservoer
What type of water should you run in if you don't run 50/50 mix? Isn't distillers bad to run? Also, I love in Texas. People say you're supposed to at least run 15% antifreeze with water. I don't think that's necessary because it doesn't get below 75°F even at night, but that won't mess anything up will it? Thanks in advance
I meant to say "isn't distilled water bad to run in the system?"
+TwoWheeledMisfit I heard something about it and I actually think you are supposed to use distilled water, their is a channel called chrisfix if you don't know already but he did a good video on how to do a complete radiator flush and he explains it all
+BeetlexVW thanks!
+TwoWheeledMisfit no problem, I actually live in Texas too I went to autozone and just picked up a pre-mixed 50/50 antifreeze
+BeetlexVW sweet! I want to put a coolant additive in and it said not to use distilled water with it that why I was confused. But thanks again for help!
You didn't mention turning the heat on
Can you make a video or just tell us about your engineering background? What school, what company... I would really appreciate it!
