A car engine produces a lot of heat when it is running, and must be cooled continuously to avoid engine damage.
Generally this is done by circulating coolant liquid usually water mixed with an antifreeze solution through special cooling passages. Some engines are cooled by air flowing over finned cylinder casings.
A water-cooled engine block and cylinder head have interconnected coolant channels running through them. At the top of the cylinder head all the channels converge to a single outlet.
A pump, driven by a pulley and belt from the crankshaft, drives hot coolant out of the engine to the radiator, which is a form of heat exchanger.
Unwanted heat is passed from the radiator into the air stream, and the cooled liquid then returns to an inlet at the bottom of the block and flows back into the channels again.
Usually the pump sends coolant up through the engine and down through the radiator, taking advantage of the fact that hot water expands, becomes lighter and rises above cool water when heated. Its natural tendency is to flow upwards, and the pump assists circulation.
The radiator is linked to the engine by rubber hoses, and has a top and bottom tank connected by a core a bank of many fine tubes.
The tubes pass through holes in a stack of thin sheet-metal fins, so that the core has a very large surface area and can lose heat rapidly to the cooler air passing through it.
On older cars the tubes run vertically, but modern, low-fronted cars have crossflow radiators with tubes that run from side to side.
In an engine at its ordinary working temperature, the coolant is only just below normal boiling point.
The risk of boiling is avoided by increasing the pressure in the system, which raises the boiling point.
The extra pressure is limited by the radiator cap, which has a pressure valve in it. Excessive pressure opens the valve, and coolant flows out through an overflow pipe.
In a cooling system of this type there is a continual slight loss of coolant if the engine runs very hot. The system needs topping up from time to time.
Later cars have a sealed system in which any overflow goes into an expansion tank, from which it is sucked back into the engine when the remaining liquid cools

Sir coolent or water ktna hona chea or coolent maine distel water jo baatery maine use hota ha kia distel water ko b rediator maine use kr saktea haine???
@@usmanghani2371 use ethylene glycol for proper cooling.
Hose pipe ya horse pipe
Maximum temperature Generate 2500 degree Celsius

Sir mera ek question hai ki rediator kyu vehicle ke aage hi lagaya jata hai kya reasons hai ki piche nhi lagaya jata hair

Very informative video. Specially the tip at 00:38 - 00:40 that cooling system is not for cooling the engine but is for maintaining the temperature of engine.
Nice video...my Tata ace ht have temperature or heating problem..radiator wash n clean,gasket replace done...but still over heats...plz help
Gajab ka video tha sir
Apne jo bhi bataya bahot hi ache tarike se bataya hai aap track ke har ek part ki jankari ka video banaye n sir please i request you

बहुत अच्छा तरीके से समझाया
1st UA-camr good explanation
इंजीनियर सरजी
इंजन ठंडा होने का टेक्नोलॉजी बढीया तरीके से हमें समझा दी धन्यवाद
Good explanation bro but there were small mistakes also like (a)heat in the cylinder is not developed because of friction , it is produced because of combustion of fuel (b) temperature inside the engine cannot be 6000 deg C, at around 700 deg C piston itself will get melted. Anyway I appreciate your knowledge. I didn't fully followed your video but fast forwarding.
Agree it is 600०c but i said 6000.
Thanks.
But heat also produced with friction..
🙏
Piston ring also genarates heat due to friction with cylinder liner but as engine oil is continually flowing, it absorbers a lot of heat...
@@nahid1981 yes bro
Any moving part create friction
Bahut hi badhiya tareeke se samjhaya aapne .doosronke videos me pata nahee chala raha tha ke coolant kaha circulate hota hai ..engine oil kaise kaam karta hai WO bhi jananaa chahata hoon.
Sir video hai .Engine lubrication system
Hello Sir,
Very informative video and you have explained the entire mechanism very clearly. I have a question. What if someone block the coolant circulation pipe. I own a diesel car and I am seeing temperature rising very quickly. How much damage it can cause? Should I have to replace the entire radiator?
Can I English version of this video ? I can't realty endesteind this language
Hello sir intercooler intake pipe mein oil evaporated hai ....Kya yeh problem hai
Nice explanation sir.i am also car mechanic from Jharkhand
Bhai old water cool radiator me coolant dal sakte hai kya pani ki jagha

mere 2017 celerio mein coolant kam hota hai. Reason kya kya ho sakta hai sir. Aur dusari baat top up kisme kare? radiator or resorvoir?
Kya sir engine ke coolant temperature sensior ko bina khole Saaf kiya ja sakta hai
Dear sir aik problem ha please solve kar dain ma nay apnay UA-cam channel say 3 ya 4 video delete ke he is ka meray channel pay ko bad effect to ni paray ga
Please guide me in this regard
Sir i have optra 2010. When ever i drive almost 70 KM it gets overheat and collent pipe get very hard with air pressure. Mechanic have replaced gaskit and waterpump but still same. When i check my self I found that pipe from reservior tank to throtle body is blocked by previous owner. Throtle body coolent pipes are very rusty. Also thermostate to throtle body pipe is blocked by putting bolt in pipe.
Is that can be a cause of pressurising and overheat?

Sir Meray pas car main rediator problem hai rediator be new hai water pump be new hai but car hear up Hoti hai jaab rediator mein phoonk martaa hun tow running shro hojataa hai so what this problem
My gypsy is overheating every time.
Coolant is full,no leakage,radiater is cleaned recently. still the problem is continue.pls suggest
Nice sir, bahut Kam ki chiz
I m confused with radiator is that radiator work as condenser when we start ac, please tell me
No.. Condenser condenses the refrigerant gas into liquid form in AC.. Whereas coolent in bike and cars are already in liquid form. In this cooling system only the liquid coolant gets cooled in radiator due to fresh air from atmosphere and that cooled liquid is passed to engine with pressure with help of water pump.
@@Deeep1522 mujhe wo baat pata hai lekin mai iss cheez mai confuse hu ki jis pipe se coolent flow hota hai usi pipe se refrigerent flow hota hai kya
@@vivekjadhav3594 Haa AC me usi pipe se refrigerant flow hota hai
Phir coolent aur refrigerent mix nahi hota kya
@@vivekjadhav3594 are bhava AC me refrigerant use hota hai.... Aur coolent Bikes and cars me use hota hai refrigerant ke badle Samajhla ka..
Sir mahindra turbo 295 bahut jyada heat kar rha he Kya kare......

Hi, I have a Maruti Suzuki SX4 VXI 2007. Due to overheating, I recently changed its Thermostat Valve and the car started working fine at the optimum temperature but as soon as i switch on the AC, the temp gauge shows drop in engine temp. Yesterday, when i again replaced that thermostat with a new one, the engine has again started overheating & the lower radiator hose is not getting hot at all. Kindly assist me as I'm not able to identify the cause of my car's problem.
