We make transparent thermostat housing

[@DKC0994]

Very interesting as always! Made me understand a thermostat better. What about a transparent brake booster next?

[@Texas21Texas]

That would be interesting to see as well

[@gabrielv.4358]

Nice idea

[@squishy312]

This is by far one of the best transparent videos yet. Even though I already know how it works, it is fascinating to see it actually work. Well done!

[@pauberrymon5892]

Truly amazing to know a wax pellet & a spring makes the thermostat operate, then to get to see it happening in real life is Epic. Great Project Guys.

[@123klaas]

Your transparent video's should be mandatory to all auto mechanic schools! 🤩 Nice to see how the air is blowing out, mostly. To see that it works gradually, to see that natural circulation is really happening! I still don't know how an automatic gearbox works and I would like to see that, plus seeing the oil in a torque converter move!

[@wilco3588]

One of the additives in antifreeze helps stop air bubble formation and suppresses cavitation so the cooling system will get less pitting ,since you're running straight water that's probably why you have more air bubbles than normal. At least that's my guess . Wilco

[@wilco3588]

In North America Chrysler Built an engine called a slant 6 which was a 6 cylinder that laid on its side about 45° for multiple reasons but was a very good engine I'd love to see someone make two together and make a V12.

[@lemau8458]

what are those reasons cause that just sounds like pointless overengineering to me. and yes v12s already exist

[@Investment_Hedgehog]

BMW inline 6 since the 70s. My 24 year old inline 4 cylinder BMW engine is also a slant. Audi, Porsche, and others also have slant engines Slant engines aren't anything new or bespoke.

[@wilco3588]

Slant 6 was designed in the late 50s and came out in 60. I'm sure the Mercedes 300 SL engine head some influence on it.

[@wilco3588]

A couple of the design goals were that you could have a lower Hood line and also the slanted engine gave you a better space to make a longer and close to equal length intake manifold

[@DolllarStone]

Too bad they dont have that slant 6 in Russia

[@volvo09]

That was awesome! I never thought a thermostat would be interesting! You can see how vigorously the water flows through the cylinder head before the radiator is introduced. I didn't expect it to be that fast.

[@honkie247]

My compliments to whoever laid the concrete blocks in your garage. That is some beautiful work.

[@jesusestrada5543]

During the winter, when I have my heater on, I can actually feel the thermostat engaging while driving on the highway. When I accelerate, I can feel the air blowing go from hot to barely even warm, as the coolant gets diverted to the radiator. So it's really cool to see this happening in real time!

[@Komeuppance]

... is your coolant low or your heater core plugged? Lol

[@regan44017]

I'd say you have a lazy or failing thermostat that's not closing fully

[@senorcartmenez8902]

My guy, you need to get that looked at

[@jesusestrada5543]

@@Komeuppance Yeah I oughta check the coolant level, can't believe that didn't occour to me. Also I'll take a crack at getting the thermostat diagnosed.

[@jeeper426]

watching technical videos about automotive cooling systems, and things like that always use basicly depections of how fluid is "supposed to pass through an engine" with your transparent thermostat housing you actually make it extremely clear how the system works in an actual working engine, very cool experiment and quite a bit of useful knowledge, stay safe guys, and i hope we can get more content like this in the future

[@Danielagostinho21]

loved the explanation about coolant circulation after shutdown

[@whoknows8225]

outdoor fire heated hot-tubs work this way as well

[@jasonbirch1182]

The top port is not being closed as it would in a normal housing. It's only opening the bottom. That disc that moves up when it gets hot would seat on a surface to close the bypass port. You get the idea here though. I would like to see if it sets a particular rate of flow on a highway drive.

[@nicholasweiss4662]

But it does. Theres an inner tube in the housing that the top plate pushes against.

[@micheskillz]

correct jason!

@@nicholasweiss4662 no.

[@jasonbirch1182]

​@nicholasweiss4662 interesting. You are correct. Not sure how I missed that.

[@neatt3815]

How about a clear radiator cap and clear radiator neck with the overflow hose? It'll be interesting to see what it looks like when the pressure exceeds the cap rating causing the radiator to dump coolant into the overflow and then sucking it back in the radiator when it cools down 😁 (could be incredibly dangerous though 😬)

the most fascinating part was the after the engine shut off part, where the fluid kept flowing. all my years around cars I never stopped to think that after shutting it off that there might still be any flow. I wondered how the engine never ran into thermal runaway once you shut it off and that mechanical pump stopped. I always wanted to buy a electrical pump to keep the flow going for a bit after shutting off the engine but thanks to this, I now know that would not have mattered all that much. awesome.

[@7mgte490]

Very good video, educational. I also watched the transparent window gearbox too 👍

[@busyguy7479]

if nothing was proved here other than the work put into making the enclosure it still was fun kudos to you guys that make these videos . so Vlad keep up with the fascinating videos.

[@666louis]

Excellent demonstration, thank you.

[@pierrecarlsson902]

Like a boatpropeller make bubbles due to the difference in pressure on the opposite sides of the blades, the waterpumpimpeller make the same effect. The more the engine revs, the worse the effect will get! Eliminate the surface tension will help a little, but optimal coolingfluid aviable is in fact a special oil. This will also help the engine get to a more efficient working temperature as it's not limited to a certain temperature to avoid more bubbles that decrease efficiness. A aluminiumhead for example does not warp at 120 degree celcius, but there is only air in the waterjacket that allow a higher temp on the combustionside of the head than the camshaft side that create the tension that warp. Cast Iron does not warp, so there the clearings of fittings decrease and pinch (if oil gets hot enough to make itself solid) camshaft or (most likely) piston. You should test and put oil in coolingsystem to check it out!

Thank u so much for making this video. I never really knew how the thermostat actually worked .like how it looks as it flows. Its so cool to see how engines operate. 👍🙂 you guys are the best.ur videos are always fun and great.i learn new things and ur videos are also very enjoyable

[@observingrogue7652]

Thank you guys for this. It was awesome to watch.

[@adamscott9725]

Like the transparent projects, seeing things work in real time is good stuff that said my thoughts are to remove the thermostat and mechanical water pump and replace it with an electric pump which can double as a thermostat just by not turning on until desired temperature not to mention HP gains from losing the mechanical drag of the mechanical pump. Plus, you could control the coolant flow rate, thus allowing the coolant to stay in the radiator longer, which would drop the temperature even more if need be due to ambient temperatures as well as engine loads.

[@rustybux]

you have it backwards. Upper radiator hose and lower hose. Hot engine water heats up the bottom of the the thermostat and lets the hot water go into the upper hose and down the radiator to cool the water. Looks like you have hot water at the top of the thermostat.

[@laurenbina4188]

The shimmer was a great touch! 👌👌🤙

[@busyguy7479]

the machining of the plastic parts is very good . talent at its best.

[@twocvbloke]

And at the heart of it all, is wax, yep, wax, the brass bit in the middle is called a "wax motor" and provides the actuation force as it heats up, as wax expands quite readily, forcing out the plunger that shoves things open... :)

[@glowiever]

and the wax is trapped inside?

[@twocvbloke]

@@glowiever Yep, baiscally a compressed pellet of the stuff that's shoved in with seals and crimped tight, it's when those seals fail with age and the wax squirts out that the things stop working...

[@JJFX-]

The cool thing about wax motors aside from reliably is the absurd amount of force they can overcome.

[@vasiliansotirov6976]

The right circulation is when the big circuit opens, the small should close. This is how it is on a stock Lada thermostat. Otherwise as you can see the water flows primarily from the small circuit as it has less resistance to flow.

[@Dat_Sun]

Make a lada fast response fire or bilge pump using lada water pumps. How far/fast can a Lada pump water?

[@wilco3588]

Another great video I love the visual ones as well as some of your more silly stuff haha. Wilco

[@FijiLaw]

Very educational, thanks!

[@garagegamer6484]

The open and closing of the thermostat is happening because of the sudden flow of fresh cool water from the radiator. As soon as the thermostat opens and enough cooler coolant from the radiator passes the thermostat to cool it off it shuts again.

[@DarkLinkAD]

Not so sudden, even at 50x. Its just gas within a diaphram.

[@skurblord3401]

Exactly. After a long enough time the radiator will get heat soaked and it will remain open without the pulsing.

[@CotyRiddle]

@@skurblord3401 that usually happens in hot weather after sitting for a long time in traffic. Under normal driving conditions you should never have a heat-soaked situation unless the radiator is undersized.

[@volvo09]

@@CotyRiddle correct, while driving it should be fairly well closed to maintain engine temp, the radiator isn't fully hot and circulated unless under a tremendous load or you are stopped.

[@Mrshotshell]

@@DarkLinkAD Thermostats actually use wax that expands when melted to open it. It's called a wax motor and is used in quite a few temperature control applications

[@Erik_Swiger]

Great video! Useful and informative, and fun as hell to watch. For some reason, in my mind, the flow always seemed much more sluggish. This was great to watch.

[@1marcelfilms]

Now get clear coolant and a DYE that changes color based on temp

[@jameshedrick605]

That would be cool to see then you would be able to know what the coolant temp is without a temp gauge

[@TdrSld]

Automotive Engineer here, that type of Thermostat design is a tempering valve setup, The reason the valve is opening and closing all the time is to maintain a target temp for the water going into the engine. We learned years ago that having the water straight from the rad is very bad, especially if the water pump shots that very cold water (relative to the cylinder temp) right on the outer cylinder wall jacket. The old Ford inline sixes were very bad about having cracks on the number cylinder because of this very thing, as the water pump shot the water right onto the front lower side of number one cylinder. Think about were you are in Russia and the temps y'all see in the winter. A radiator is nothing more than an thermal battery, so if the air out side is at X temp and you let it in it's full temp run straight into the engine (Like on a -30*C day) you could imagine the stock the engine will have once the thermostat opens. So what your watching is the thermostat metering the cool water from the rad into the inlet of the water pump to maintain a operating temp with in X degree's of the engineer design. This keeps the engine from seeing very cold water that may be setting in side the rad on extremely cold days. And on the flip side on very hot days (like were I'm at in South Texas we can see 48*C days for weeks on end) the valve will more than likely complete close off the small loop and run completely off the rad to keep everything in check. Love the videos guy's, y'all keep them coming.

[@freiduumforall8843]

So is this what they refer to as a by-pass thermostat system?…..cool water from the rad mixing with the rest of circulating coolant when the thermo opens?

[@TdrSld]

​@@freiduumforall8843 I cant tell by your use of by-pass thermostat how you're using the word by-pass. As I see By-pass as completely removing or going around another thing. I have a By-pass T-stat on the trans mission of my truck (2010 Tundra), it's job is to by-pass the liquid to liquid trans cooler and send the trans fluid to a much larger air to liquid cooler Infront of the rad. It does this because the liquid to liquid cooler is only good for X BTU's of heat transfer and when towing or driving the truck hard (like extreme off roading in low range) it just can't keep up with the heat. So Toyota on the MAX tow package equipped trucks added this air to liquid cooler and use a by-pass t-stat to By-pass the L to L down on the side of the trans when it can't keep up.

[@jameswitkowski6736]

Still fun seeing the workings .

[@JoejjjaGames]

Can we see clear timing cover on an engine with variable timing and tensioner?

[@ruikazane5123]

Clear water pump next? Or brake calipers and master cylinder? Have to prove that the main seal does NOT twist or rotate but rather squegee the piston and pull it back very slightly after relieving pressure. All the way to a clear engine block!

[@christicristian06]

Well we know that the piston doesn't rotate at least not on front brakes, it does on the rear ones. They did something close to i think a transparent engine head.

[@65bug519]

Thank you gentlemen, I have educated today. You should now make a transparent carby and mount it in the trunk to see if you can make it run like that.

[@SoulPurposeGarage]

Pretty cool! I believe the reason it closed is because cold liquid was added and dropped the temperature down causing the thermostat to close up

[@Triplechorus2]

Very informative experiment, thank you! Now I know that the coolant still moves for a while after shutting down the engine.

[@elaineinmaine7971]

I Like the Idea 💡 to view the thermostat functioning

[@ArvineHarry]

Great project, just a thought, the continuous air bubbles appearing in the flow could be from gases in solution / dissolved in the fluid, like when boiling water, bubbles appear on the surfaces of the container being heated, was the radiator cap left open during this exercise?

[@dancoulson6579]

I think it will be a gradual motion. Not an instantanious switchover. A gradual changeover will allow a perfect ratio to settle. For example, on a cold day idling 100% may be in bypass. But on a hot day idling maybe 90% bypass and 10% radiator. Just my hypothesis.

Cool video! it looks like thermostats are restrictive by design, is there a way to speed up flow by modifying the thermostat / housing ?

[@scorpion-in2xj]

The hole housing is upside down top hose is bottom of the radiator. But as it is ir still works good. Thermostat is like a tap slowly being turned on. Which gradually increases the temperature in the engine..

[@TheHortond]

That's a weird way for a thermostat to work. I thought it kept water in the engine and let it get to temp then sent it through the rad to cool down while closing off to keep the engine hot. This one seems to do it different.

[@crisnmaryfam7344]

Well, what thats all about its, One thermostats have a tiny hole in them to allow some bypass. They also, open and close depending on the temp... So if you were riding the thermostat specification line, that would be why. Given the Odd way you incorporated it, Its possible the unnatural flow is having something to do with that. OR its just how a Lada operates. Ive never seen one of these cars in the states, much less had to work on one.

I have challenge for you. Have you ever heard of making more compression by taking heads from a small engine and puting it on a bigger engine that matches? (A 350 small block with 305 heads for example)

[@dkostasx]

The idea is good, but it was not very clear where the liquid is moving or where it should move, because the top hose was not transparent. It could be better if you could add maybe some arrows showing how the liquid should move in one loop and the other. It looks like before the thermostat was open the liquid moved from the top hose to the upper right hose. Then after it opens it looks like the liquid is moving from the bottom right hose to the upper right hose, but it is not clear what is happening with the top hose. Moreover, you could add some thermometers to the tubes which would show the temperature of liquids in each tube
