How to TEST Your Coolant for the Winter (Before Major DAMAGE is Done)

Datum objavljivanja: 7. Pro 2020.
Learn how to test your antifreeze, and how to change your coolant to make sure it is protecting your car's engine and cooling system properly. In this video I cover what how to properly test your coolant and top off your radiator so it is a 50/50 mix that way your car wont overheat and your engine block wont freeze or corrode.
Also if the heat in your car is weak or you dont have heat, in this video I will show you how to bleed the air out of the cooling system so you can get heat Coolant is 50% antifreeze and 50% distilled water. And no, freeze plugs are not going to save your engine block from freezing and cracking every time.

  • Just dropped brand new DriftStang "Ugly Sweaters" which are actually really comfy: This is an important video I wanted to get out asap before the really cold part of winter sets in! Here are some other related videos: How to SUPER FLUSH your Coolant: How to Flush your Heater Core: How to Diagnose and Fix NO Heat in your Car:

    • @Shashank Sagar i did not mean all that taking it too far i know. That its not bad.. Last time im commenting on a video

    • @Krischen Price do note that that some people get away with calling some things the wrong way, and it in fact becomes their identity, that this man calls this thing this way and not that way. Christopher is also one of them, with his identity becoming him always calling water as 'wooder'.

    • Why did you write wooder on one of the pipes... Do you mean water?

    • Do you still have the D16 Civic?

    • Hold up, What happens when I fill my car's radiator with antifreeze more than distilled water? Yeah, the solution is simple, I can easily add plain distilled water, but I am very curious on what happens in this case.

  • Hello Chris, I have a question. You say at 10:40 that there is no problem if you come a little over the maximum line with the cooling fluid. But when I use the Spill Proof Funnel, I am actually very much above the maximum line. Actually, the liquid is then filled all the way to the top. Do I have to take liquid out until it is at the maximum line? Greetings from Germany. PS: Cool that you now have a German car :)

  • Hey guyssss I appreciated it lol

  • No body in this world explain much more better than this .... Fantastic explanation ... Thanks a lot .. Your brother from india...

  • How the 🤬 does he have that meany cars

  • Are we allowed to use a funnel for topping off the washer fluid?

  • Sorry if this has been asked already, but I doubt it has because I can't find the info anywhere. I'd like to test my coolant, but I'm finding it difficult to understand why everybody is checking the fluid not from the radiator itself, but from the reservoir. From my understanding from what I have read, the expansion reservoir does not actually circulate coolant through the system, it only acts as to 1.) not allow overflow from spilling onto the ground, 2.) does not allow air to enter the system, and 3.) maintains 100% fill in the system if there is a leak, or other issues, such as burn off, or whatever. If what I'm reading is correct, the only time the liquid in the overflow tank could actually be sucked into the system is possible during the expanding / contracting process, or if there is a leak / burn off of the liquid within the circulatory system. So, if people are checking the reservoir for proper concentration of the liquid within the system, isn't that completely incorrect? Please learn me here... I'm dumbfounded and probably wrong.


  • I have a bunch of question... I have rust in my radiator and its leaking at about 12 blade no's of the radiator and it was totalled to be weld... When I'm buying aftermarket radiator, it stated on the box "DON'T USE COOLANT" So, i used filtered water as my radiator coolant... My question is 1. Why the warning for not using coolant?? 2. If i wanted to use antifreeze and antirust, it is gonna effect the radiator? 3. My radiator still have rusty water, is it normal?

  • This stuff about winter makes me laugh. I am in Western Australia, we think anything below 60 degrees fahrenheit is cold. We never have freezing issues. A slight bit of ice on the windscreen in winter is an extremely big deal!

  • Where did you find the source that says freezecaps are just holes from manifacturing? thnaks

  • @baselissavage

  • Greetings from Turkey Hi I'm doing a little workshop I had such a loving expression in Turkey Thank you so much for the information you would follow bro Thank you Thank you for your information

  • Thank you very much for giving such information brochure Greetings from Turkey

  • Face reveal when?

  • what happens when you dont put 50 50antifreeze and water but instead you but 100percent antifreeze

  • where js the driftstang 0-0

  • Do keep in mind that distilled water does transfer heat away from components better than straight antifreeze, so if you live in hotter climates that does not see freezing temperatures you can mix more distilled water than antifreeze such as what was in the Jaguar for more effective cooling. Other than that, great video Chris!

  • That 50/50 mix isn't that important, just have it around the freezing temp you need it, if you have 65/35 antifreeze it's ok, don't make it a math challenge xD

  • I remember back in the day when me and my buddies had to cover my cars hood with a thick blanket and park it in a wind resistant spot becuse my Waterpump was leaking and i put pure water in the cooling System. It was like -10 Celsius and I really was woried that my cars Block would crack,so much so I drove it hard to get it up to temperature and then let it sit thru the night... Remember it to this day,nice Video Chris,keep it up Buddy,can't wait for the Turbo Del-Sol video.😁

  • The spill proof is actually amazing it has really helped me when I’ve had to flush 2 different radiators, and it makes getting the air out so easy that A kid could do it

  • Wow nice bro! King!!!

  • Well my Lil Japanese car is toast! Live in Canada and it's been -50 for a week. Dang

    • @ChrisFix I have no clue, whatever coolant it had in Japan. But all I know is there's probably not a lot of antifreeze in there. Goodbye engine block.

    • What ratio do you have in there now?

  • good nice

  • This is a spare engine I have

  • Nice video Chris. You could take testing of coolant a little further though. This method only tells you that the coolant is strong enough to stop your car from overheating or the coolant freezing it doesn't tell you if the corrosion inhibitors are still doing their job. To do this use a multimeter. Set it to millivolts scale DC or 20vDC .Put the negative probe on a good ground and the positive probe in to the Antifreeze. The reading should be below 200 millivolts or 0.2v. Anything higher means that the inhibitors are failing and there is an electrolytic reaction taking place. Give it a go.

  • Bro I live in California, we don’t have to worry about the cold 🥶

  • Was wooder a joke or just him.

  • 10:12 I see no watet

  • Iv just had to do a coolant flush on my car. Brilliant for saving money if you know what your doing

  • Can‘t i just put 100 instead of 50/50 ?

  • How about 75/25 ratio is it good?

    • What kind of climate do you live in?

  • Will the drift car actually get the new engine because you said you will try to get the PI supercharger to work with the stock engine. Also will the car get big cams someday? And lastly can we expect the supercharger video to come out this year or will it probably be next year?

  • why don't we fill the entire thing with anti-freeze?

    • Coolant needs the properties of water for heat dissipation and to reduce the freezing point for it to work!

  • Face reveal

  • thank you im going through and watching all your videos

  • Crisfix is my daddy

  • is there any benefit to buying 100% antifreeze and mixing yourself or just getting the gallons of 50/50 premix?

  • I don't know why, but suddenly i crave for green apple juice =))

  • I use the Prestone Deicer fluid in my washer fluid reservoir. I also use the Prestone Deicer fluid in spray bottles to deice the windshield and windows when there is ice on them and let it sit and most of the time I don't have to do any scraping. You can find Prestone Deicer at Walmart or Dollar General or even on Amazon

  • So if I live in a place where it gets colder than 34 degrees Fahrenheit should I just not put in any coolant?

  • Snap to transform, flick to freeze! HRwiki Midas touch!

  • You like doing science

  • Can we use that to bikes too?? So they can't freeze .can we??

  • Not gonna lie ChrisFix is a teacher for cars thanks MrChrisFix

  • he know its called water right😂😂

  • Why is he calling "Antifreeze" "Anyfreeze"?

  • Do more humer videos

  • Oh geez, math always confuses me 🤔

  • Hahaha. My dad and I serviced coolant for an old project truck and we opened it while it was hot.

  • Why am I watching this? I'm not old enough to have a car, let alone be fixing one, and I have a test in 2 hours.

  • wait... why do u spell water as wooder?

    • That's how it sounds when I say it haha

  • Love from Srilanka Chris 🇱🇰

  • Did Chris say supercharge the Driftstang?? Yayyyyyy more videossssss love ur videos man I've been a fan scince u bought the driftstang. It feels like yesterday me clicking on chrises video abt a driftcar god it feels like yesterday ❤❤❤

  • 4:34 im sorry, what? For real? Oh boy, imma stay up all night thinking about that... its gonna be so sick

  • Is it okay to use a gas tank that has not had gas in it as an oil drain?

  • My Car I don't need to change the coolant ever because it doesn't go bad, It just leaks out, and when it goes down a bit and add more, so it can't go bad

  • Dear mr chris fix. If you ever get a chance can you do a video on repairing the grid lines on a rear window? Thanks. (The black lines on the back window for the rear defroster)

  • Who else watches these videos for entertainment XD

  • So it's better to have a 50/50 than just only antifreeze on the car?

  • I wish I had watched this video sooner. I currently have my car in a shop, because my coolant froze :/ They're expecting a total cost of about $900.

  • Interesting water pump gets destroyed by water.

  • I wonder where you live what Country or state

  • @ChrisFix you are the best youtuber. Hands down.

  • when will you super charge the driftstang

  • Only Chris fix would make pipebombs yo prove a joint

  • The forbidden MountainDew

  • Why does the coolant look so tempting to drink

  • i bought a RAV 4 2001 and when i checked the water it was a normal water clean and no dust or something , but is it safe to use a GREEN water without damaging anything ? im not sure thanks

    • You should be able to use universal coolant in your Rav 4 with no issues, I would drain that out and fill with the proper coolant level and coolant ratio. I have a video on that here, check it out:

  • Water will rust out the freeze plus I've replaced enough freeze plugs to buy a new car

  • I am a man of my words when I say chris fix wont reply to this comment he wont

  • freezing plug ?

  • Chris. I never comment on HRwiki. But thank you for everything. thank you.

  • The stig is Chris fix???

  • Idk why but I am really tempted to drink the antifreeze.

  • Man when are you going to work again with the del Sol

  • Chris you very smart and i bet your favorite subject in school is Science

  • Oops i forgot to winterize my jet skis


  • Best engine oil Royal Purple HPS and use there filter. Best fuel injector cleaner BG products Best Air filter and cabin air filter are made by WIX Best windshield wiper fluid Ran X 2 and 1 all season. Best wipers Trico Titan. Best rotors for cheap Power Stop. Use ceramic brake pads. Change serpentine belt at 80,000 miles to be safe. Change wiper arms every few years the springs get weak Flush all fluid at recommended times. Check ball joint and ball bearings once a year Check tire air pressure once a week Maintain the vehicle so it last a long time a lot of people don't do this.

  • One more thing u forgot to mention about the waterpump, its that antifreeze also lubricates the system and the waterpump. Very good video 👍🏼

  • what happens if you use only Antifreeze 100% Antifreeze

  • Chris, why do you go to the extreme to conceal your identity? Is it because of your safety or you don't want to be recognized in public and have a bunch of paparazzi after you?

    • You do a great job and you seem to be pretty quick! And you’re very organized from what videos I’ve watched of your channel!!

    • I want to help and teach you guys and make the point of the content what I'm showing, it's not all about me haha

  • im impressed that the block on the truck was intact.

    • Definitely needed the fresh coolant haha

  • wooder or is it water

  • 18:19 i swear he has explained this probably 74 times

  • Wooder from engin cooling sistm tasts gud

    • @ChrisFix you help me clean my car with your videos, i have a old car :)

    • Yes :p

  • Oh no my dad uses water from the hose in his cars no antifreeze 😨 old cars he has but still i better tell him about this very helpful video!

    • We just use coolant and water out of the hose. Our cars last about 20 to 30 years. I doubt a little bit of chlorine is going to hurt.

    • That'll cause problems given enough time! Pure distilled water and coolant are the only things that should be in your coolant system!

  • Hi Chris just wondering if I have antifreeze in my car can I just add more of a different brand or should I not mix?

  • did you guys notice instead of writing water he wrote wooder

  • Hey chris! just a question, are you a mechanic before, before u start ur youtube channel???

    • @ChrisFix okay cool btw ilove all of ur videos haha!!

    • @ChrisFix but without being an actually trained mechanic.

    • I've been working on cars since I was young with my Dad, and over the years I got to do bigger and bigger projects to where we're at today!

  • Chris...question on the Coolant? I have a 2000 Tahoe w/ 315,000 miles now... Is it ok to use straight Coolant w/ no water mix?? I prefer that ....

  • Another great video; well done. One suggestion for changing out your windshield washer reservoir: use a fluid evacuator and pull the old fluid out to empty the reservoir, then add your winter fluid and activate the wiper washers until the new fluid flushes through. Thank you for all of the great info.

  • Why do you say water like this wooder

  • Why do you say wooder it's water

  • Hello, have a question for you Chrisfix, are you a mechanic or how do you know how to do all these things?


  • "Winter is right around the corner" In December? Lmao

  • Omg engine for di driftestang supercharged omg I wait for dat for soooooo long 😱😱😱

  • So that's why I can't
