How Car Cooling System Works

Watch the animated video on how the engine cooling system in an automobile works.

[@tommyv4980]

I am impressed by the level of work that has gone into this. Fucking brilliant.

[@Brandon68plus1]

Master mechanics deserve a lot more credit and they shouldn’t even have to get their hands dirty at all just stand and point. You almost need a doctorate degree to understand these vehicles now. Great video.

Right! This is kind of mind blowing how this all works for a car! 🤯

[@baileyforrester7]

I’m sure it’s been said 1000x already but this is an amazing visual representation of the cooling system on an engine. I enjoy the animated aspects of this as it’s very clear. Amazing work!

[@kw9694]

I wish this animation technology existed when I was young, so vividly explained; so much simpler than a book. I played the video at a reduced speed to really allow the dynamics to sink in, snd master it thoroughly . Thanks a million, an old school 60 year old, now in the know when visiting the repair shop.

[@Redtooth75]

Thermostates are usually set to 190-210 degrees Fahrenheit. Not 200-250 degrees Celsius like you stated in the video. 200 degrees Celsius is 392 degrees Fahrenheit, at which point the coolant would boil.

[@makantahi3731]

even 250F is too high for operating temp

[@Redtooth75]

@@ryancox6268 very incorrect. The pressure raises the boiling point it does not make it nonexistent. A 50/50 mix of glycol and water at 15 psi boils at 268 degrees F.

[@prandomable]

​@@makantahi3731250F is above boiling point for water😂😅.

[@prandomable]

​@@Redtooth75the SAME logic applies to boiling water at HIGH altitude. Up in the mountain it takes LOWER temperature to boil water BECAUSE of lower atmospheric pressure. Same concept same logic.

[@makantahi3731]

🤣🤣🤣🤣🤣🤣🤣 who said that water is in engine cooling system🤣🤣🤣🤣, you should know that there is mixture of some kind of coolant fluid and distilled water and boiling point of it is 5-7 C deg over pure water at ambient pressure🤣😂🤣😂, and if temperature raises and approaches boiling point, pressure starts to raise and that moves up boiling point and cooling system is adjusted to keep up to 1.5-2 bars over ambient pressure, so coolant can hit over 110C deg before starts to boil🤣😂🤣😂🤣😂🤣 @@prandomable

[@Unclenate1000]

i always get worried every time i watch videos like these and see how much complexity there really is in all of these systems, and how much could go wrong

[@RzVids]

If your car overheats, don't ignore it. You can blow your head gasket like that :P

thankfully mine doesn't, even in 100+ weather, but i cant still help but be nervous

[@joshhadada9772]

its just a lot of quite basic things working together you just have to take some time to do the steps its really simple when you look at the pieces individually it becomes like a puzzle which you already know where all the pieces go.

adding coolant to a over heated engine can also blow the head gasket

[@deanomutch6175]

Lots of people think cars are hugely daunting, they have no clue how easy and simple they really are and the mechanics / physics behind them. I do everything on my car myself, it's incredibly simple, well structured engineering. You will easily learn how a car works within 10 minutes or less nowadays. This video as well explains the cooling system with so much detail, credit where credit's due it is so simple to follow along too I'm sure everyone who has never lifted a spanner would understand it after watching.

[@gum7719]

the puzzle the engineers had to figure out was pressure, at least i think. If it gets hot enough, open this, if this gets hot enough open that. I really wanted to know exactly where the coolant was going inside of the engine and it made complete sense right at the beginning, thanks. Every mechanic should see this asap. And I did know what a radiator was but I didn't know exactly how it works, it cools down the coolant to send it back to the engine. Very informative.

interesting mechanics for non mechanic person like me

[@lupuszzz]

Let me correct some comments in your video: *) 1:10: At cold start the water is not coming from the lower tank of the radiator, but it is circulated in the engine only - you would generate a vakuum in the radiator! *) 1:50: 200-250°C operating temperatur is just wrong - it is in fact in most cars the opening temperature for the thermostat is about 82°C. *) 3:40: The fan is only actuated in case the temperatur in the radiator gets too high (e.g. ON-low power: ~92°C, ON-high power: 98°C, OFF: 88°C) - and not because coolant flows out outside the thermostat.

You just reassured me on how my system works so I can properly flush the system and restore the car...thank you!

[@alphasiera1757]

So how does the coolant from reservoir go back to the radiator?

[@wot48320]

When the coolant cools down, a vacuum is presented in the radiator. It will suck the coolant from the reservoir back to the radiator, a check valve inside the radiator cap allows it flow backward.

[@alphasiera1757]

Wot48 thanks!

[@Phi1Productions]

I thought the coolant is pushed forward from the pressure generated by the water pump. I guess I was wrong all this time.

[@ClaudiuB]

Same here

[@markk3652]

@@Phi1Productions the coolant is pushed from the radiator to the recovery tank as the temperature rises, pressure rises, and the coolant actually expands from the heat. As it cools, it takes up less space, becomes denser, and effectively shrinks. As it does, it creates a vacuum in the cooling system. Nature hates a vacuum, so the coolant that was pushed into the recovery tank, is now drawn back in, replacing the vacuum space with coolant. This is why the level in the recovery tank has to be above a certain level, so air is not drawn into the cooling system. If air gets in, it causes bubbles in the coolant, this prevents the coolant from absorbing engine heat properly, and will force the coolant to boil, which is what overheating basically is.

[@livefreediepretty]

excellent vid - except it doesn't show the full cycle of how the overflow tank works - giving it had an outlet at the bottom of overflow i was waiting to see how the coolant got back into the main system

[@gianpaolo18]

I was waiting for the same info haha

[@thias000]

gianpaolo18 When the coolant gets very hot (>110 degrees celcius approx) it will start to seep out of the radiator and into the overflow (also called expansion) tank; the coolant needs to have a means of escape as it expands to prevent damage to the cooling system. When the cooling system cools down again (once engine is switched off for instance) a vacuum will begin to form in the radiator/cooling system. As the vacuum forms, a valve automatically opens inside the radiator cap and the coolant is drawn back into the radiator from the overflow tank.

[@andre1980ytube]

thias000 is right except that the return valve is not in the radiator cap for the example shown in the video. The example has the return line at the bottom of the expansion tank. So the return valve must be on that line.

[@jimmyhyl2011]

gianpaolo18 Me too. how does it work to return the overflow water to the tank.

[@nojunkorspam]

thias000 I was also curious about this because I was under the impression that the overflow/expansion tank used the same tube to fill as it does to drain, but I suppose it doesn't have to work that way.

The temperature gauge on the dashboard - surely it should measure the engine temperature instead of the coolant temperature? The gauge could just be measuring air temperature while the engine is being cooked!

[@Redtooth75]

The coolant temperature is the engine temperature.

[@AndrewS-lk4pt]

Here's a hint, when you put a new speech bubble on the screen, just pause what's going on in the background so the reader has a chance to read it. Too many times, a speech bubble comes up and then a second later, animation starts and sometimes the location of the speech bubble is even changed. I was so scared of missing the animation that I would skip reading the speech bubble and then I wouldn't know what was going on.

anyone notice the 200-250 degrees C ?? really?!! that's twice boiling lol I'm sure he meant 200-250 degrees F

[@mohager101]

I noticed that too, but maybe due to the pressure of coolant inside the tubes, the boiling point of water is going to change too due to pressure change .

[@doodskie999]

well thats normal temperatures for some diesel engines, especially old diesel engines.

[@13aceofspades13]

Most gasoline engines operate at temperatures fluxuating between 190 to 220 degrees.

[@Coyote27981]

190-220 degrees? really? with no scale? 190-220º K = solid water 190-220º F = liquid water (as long as the coolant circuit is pressurized, which raises the boiling point of water) 190-220º C = gaseous water you kind missed an important detail you know ... coolant circuit is pressurized, so water wont boil at 100c, but still it cant go much further than that. normal operating temperature ranges from 90c to 110c. Most modern cars run 105c thermostats, cause higher temperature improves emissions.

[@lupuszzz]

It is just wrong in the video. Regular coolant temperatures are usually between 82°C and 102°C, Oil temperatures are about 120°C to 150°C (150°C max for oil/air cooled engines), the cylinder head get's up to 250°C and the cylinder walls are about 85°C (like the coolant temperature), Pistons have a very special temperature profile over their zones from 100°C (bottom outside) to more than 220°C at the middle of the piston (Petrol engines) and from 80°C to 250°C at Diesel engines.

[@wkndbikeshop]

it's why water is mix with coolant & the cooling system use pressure to increase boiling point

[@offroader22]

big flaw. your saying the engine operating temperature is around 200ºC to 250ºC. dont know where you got that information from but water boils at 100ºC. at 200ºF its still hot for a engine to operate properly.

[@tabithaschultz6308]

+Fernando Melo The coolant mixture is 50/50 in water and antifreeze (usually ethylene glycol) which not only lowers the freezing point of the coolant, but also raises the boiling point of the coolant. Thus, the coolant can take away even more heat from the engine without the entire system overheating.

[@zfernadz]

thats not the point. the water in the mixture will boil once it reches its temperature. im preatu sure that the maximum operation temperature is 90ºc for a engine

[@tabithaschultz6308]

Fernando Melo The antifreeze mixed with the water prevents it from boiling. auto.howstuffworks.com/cooling-system3.htm And he probably meant Farenheit instead of Celsius.

[@zfernadz]

not really. unless you use a old school hot bulb engine i don't believe that you will ever get close to that temperature

Thank you for saving me a 100's bucks. I thought my radiator fan isn't working when I start the car engine. I thought it should had started as soon as the car starts but after watching this video it is clear to me that the fan gets activated when the coolant has reached to a certain temperature. And rest after the fan does the work of cooling the coolant and circulating it through the reservoir chamber and thus it goes to the engine cooling chambers. Thanks a ton for the video...
