That was awesome! My father was a mechanic in the army and I spent a fair amount of time helping unwillingly. Now I actually own a car this information is now relevant in my life and thanks to my father that I at least knew the names of these components! Great to see how it all works together
Great little and well put-together ground school as a refresher course and as an introduction to those who had always wondered why.... Kudos and thanks...! Gordon
This video was exactly what I was looking for. I might even download this in case you guys ever take it down I’ll have it in my personal files to watch again.
Trevor Walker the car will overheat VERY quickly within minutes of starting, you can check it by taking it out and putting it into BOILING hot water.. if it closes then it’s not the problem
@@foozayfooz9503 not necessarily, it could open right away or early and then your car takes a long time to heat up. It'll overheat fast only if it's stuck shut. There's a few different things that can go wrong with them. I replaced mine recently and it solved a few problems that I didn't even realize were related.
𖥠 ꧁Æ♱ℍᴲᮄℜᴲⅅ꧂𖥠 oh really? So I just brought a whole new engine for nothing 😩😩 the mechanic told me thermostat problems cause the car to heat up in minutes 🙄
@@foozayfooz9503 he's still right, in many cases it does, in others it takes a long time to heat up. It just depends on weather the problem with your thermostat is that it gets stuck closed or open. Thermostat gets stuck closed car heats up very fast, overheats. Got a thermostat that sticks open, car's gonna take a long time to heat up.
Cars are incredibly complex. Before I got active in DIY type of work for my car, I always thought it was easy for a mechanic to point out a problem. However, I found out very quickly that any particular problem has could be any one of five or six causes. For example, a leaking of coolant could be because of the water pump, one of the hoses, the radiator, the radiator cap, a malfunctioning sensor, etc. That's why it's good to keep up with the maintenance schedule if you can afford it.
The water pump pumps coolant into the engine via the pulley system/serpentine belt - which is what provides the energy for work to take place within the pump- and the coolant circulates via a hose into the engine block through, up and into the head, and then comes out from the engine head, where the thermostat is (the thermostat is responsible for regulating the direction of coolant flow based on the temperature of the engine - also, for those who do not know, the engine has three primary components to its frame: the block, which is the bottom piece - the gasket, which seals the head to the block and protects the combustion chamber from coolant - and the head, which is the top piece). If the car is cold then the coolant will recycle out the bottom hose back to the water pump to be recycled through the engine until it reaches operating temperature (half way point on your temp gauge in your car). Once the car reaches OT, the thermostat will close at the bottom and open at the top to cycle the hot coolant through the radiator to cool it off, and then cycle it back through the water pump to be pumped back through the engine - this is to keep the pistons from overheating and blowing your gasket, head or block...which is of the upmost importance. The overflow tank is exactly what it says. Overflow empties into the tank from the radiator, which is why the fill lines exist and one should never overfill. Also why you should fill your coolant via the radiator cap, if your car has one. Hope that helps someone...I know this is comment is 2 years old.
@@valeriestramennio9722 What are you doing over here Valerie stramennio, I can not seem to understand the reason of you learning and understanding the cooling system of an internal combustion engine, unless your like the video and the explanatory characteristics of the video or maybe you where one of the designers of this video, because I can not put two in tow together.
I run the car maintenance RU-vid channel in Korea. I'm always learning such a great ideas on your channel. I hope we have a chance to be together. Thank you.
Hi! Thank you very much for this video. You explained it very clearly and easy to comprehend. I have questions for you: I have a 6 year old Honda Accord. How come my radiator and expansion coolant tank is empty? I checked those two maybe 2 months ago and it was fine. What happened? I realized this because when I drove home, I heard fairly loud hiss coming from under the hood. I'd appreciate if you could shed some light. Thanks
I know this is old, but for educational purposes, you likely had a leak somewhere and you probably have blown your engine block or head...the loud sound.
The video is as comprehensive as it can be and I have nothing negative to say about it. It's just that I still get clouded on some parts. Hehe. Worth watching again for the second time.
R2D2 eat your heart out-Nice clean descriptive and narrative-right to the point without extra words- I know all this but was great from robot perspective
@@shifty2755 nope, engine will run fine and not break, just wont get up to operating temperature, be less fuel efficient and heater wont be warm inside the car but engine won't fail, I had one stuck open for two years before I changed it and it still runs 100% fine.
@@danallured4533 The problem is. The oil wont reach optimum operating temperature. Thus leading to premature engine wear caused by lack of lubrication.
lol! I was told by a dealer's service dept that i need a new radiator because the temp between one side and the other are different. Well....according to what I see in this video thats what is supposed to happen. Hot coolant in cool coolant out and back into engine to cool it. I really appreciate your awesome video. I thought there was something wrong with what I was told. The service writer didn't seem to know much about autos.
Thank you for integrated subtitles rather than using automatic translation subtitles for it. English is not my native language but the main issue is my bad hearing that makes difficult to understand most of the time. Subscribed.
I have a 2001 Toyota Celica that STILL has a PO115 code. I've replaced the sensor after checking to make sure the 5v reference was present. I checked the sensor I pulled out and it is Good. yet I continue to get this code. Also the temp gauge will slowly increase in temp as you drive reaching normal oper temp sit there a mintute then move up a tick beyond normal sit there a second or two then quickly move to HOT and begin flashing. I've replaced the T-Stat. Tested old T-Stat and it was good as well. **Note** I also have NO heat which lead me to believe I had a clogged heater core so I have back flushed it repeatedly using prestone flush ,air compressor and water. I still have NO heat and temp gauge is screwy. I have tried several times to get all the air out of system. I'm not sure I'm getting flow because when I removed the heater hoses very little coolant came out same with the radiator hoses and the coolant sensor I'm lost as to what the problem is I've checked the water pump and it appears to be good there no leaks anywhere in the system and there NO noise from the water pump the pulley isn't loose and does NOT move when wiggled. Anyone with any ideas would be great.
I liked it a lot ..bcoz tge video is followed with step by step manner like who does cooling then their construction m finaly the whole system ..thnxx for this .. Plz make more videos like this... It's my humble request to u 🙏🙏🙏🙏🙏
Youre fan is supposed to turn automatically on as you turn the ac on, if it doesnt start the you have a problem with your fuses, relays, modules o wires, and your going to be overheating your car if you use it like that
Then you may have two fans, and your AC is forcing the fan to work to cool down the car - which is not good for your radiator, but your engine is more important - or it could be a relay switch.
So this means that the fan is used to create draft to increase cold air coming from outside right? Like the fan doesn’t actually cool the engine but it increase the air that passes thru the radiator. Please correct me if I am wrong
