How Engine Cooling System Works In a Car

[@imaleranga6727]

Thanks for the clear explanation!

[@syndoxxx1665]

This is very informative thank you. My car is old and it takes really long to blow hot air inside the car it also stinks inside the car and under the hood when it starts blowing air.

This is beyond excellent watching from zambia

It was more than useful... Well explained...👏🏿👏🏿👏🏿

[@davedeatherage4902]

Thank you, explained simply for anyone to understand.

[@disrael2101]

Wow because of you i started falling in love with car mechanics.. Love this theoritcal combined with physical explanation.. hopefully you'll make more videos showing both sides combined like here and not just either or.. either way keep them coming just like you do lately!

Hi I installed an all-aluminium racing radiator in my Dodge ram v8 mainly because I did not want to go with a vinyl tank radiator again; vinyl tanks are crimped rather than welded. Six years ago I installed a new vinyl tank which started to leak for what ever reason. The thing is; the new aluminum radiator came with a 19psi pressure cap and it is bigger than the 18psi pressure cap which is recommended; so I can't replace the 19 with an 18. But should I be concerned with the 19 psi? Thank you for any thoughts. Frank

Hi. Thanks for the video. In the video you described how once the engine reached a certain temperature, the thermostat opens to allow the hot coolant to flow to the radiator to be cooled down, but you didn't explain what controlled or allowed the coolant from the radiator to flow into the engine via the lower radiator hose. I have been struggling to find the answer to that question. It would be great if you can tell me what controls that flow. I have a 2002 honda civic. Looking at my thermostat housing it does appear the lower hose is connected to the base of the thermostat housing, and the upper radiator hose is above the thermostat housing. My problem is that at least I have noticed when I go for short distant drives around 3 miles, (in city) the top radiator hose is always hot, but the lower radiator hose sometimes is cold--like it has never been driven--and sometimes it is hot. My engine does not overheat and my dash heater gauge is normal (half way mark). I even recently did a radiator burp, and let the engine run at park for over 40min, and while the top hose was hot, the lower hose remained cold!! I keep reading how sometimes a cold lower radiator hose, with a top hot radiator hose, is a result of a failed thermostat being stuck at the closed position, but how can this be since clearly the thermostat has to open inorder to have a hot top radiator hose? Much appreciated if you can help me understand that!

Thanks your video was very simple and informative. I'm having issues with Toyota Tazz 1.3 carb that's overheating. No leaks of coolant and the top hose from cylinder head to the top of radiator gets extremely hot. The bottom hose stats cold even when the car is hot. The fan comes on and stays on as soon as the ignition is turned on even when the car is cold. I got an technician to check it out and he's advising me to add another thermostat switch in the bottom hose of the radiator that will solve the problem. I can't understand how this will solve the problem as the bottom hose doesn't get hot. Plz assist if possible. Thanking you in advance

[@MakeItEasyMechanic]

Whenever you see one hose hot and the other cold you can bet you have an issue with the flow. If the thermostat is not opening - coolant won't flow into the radiator, so the hose where the thermostat is will be cold. Another option - poor flow in the radiator (clogged radiator). I would agree with your mechanic and try changing the thermostat first though.

[@carlodonnell146]

@@MakeItEasyMechanic What about heater hoses? the heater hose that comes out of the pump is before the thermostat I think so that is always hot even before the thermostat opens right?

[@ktp0913]

@@MakeItEasyMechanicat 5:42 you explained about the vacuum that’s created after the engine is turned off and coolant cools down. That vacuum also has to reach above the 15 psi for the vacuum valve on the radiator cap to open up?

[@nadeemkhan-is9xn]

Hi, Very nice to explain that can you explain the Hybird cooling system or you have any previous video about the coolant system because my Hybird inverter is hot I don’t know why it’s it many mechanic check it but it’s not work when I am going above 65 my car say check your Hybird system its hot When I see your video I think maybe my Hiebert inverter coolants thermostat is not work maybe I am wrong If you have any idea please share with me thank you

[@sammypandema5677]

thumbs up bruh!

[@lincoln069]

I have a doubt...whether they are using water as a coolent or any separate chemical...because u r mentioned both water and oil... Whether they use separate passage...?

[@grantp4022]

Just wondering ? does the radiator fans suck in air thru the rad to cool the coolant, or does the fans push air forward, thru the rad, and outside of the car. I get the impression after watching a couple videos including this one, that the rad fans suck in air from the outside, and thru the rad, thereby releasing this air under the hood of the car. I always thought the fans blow the air forward, and out the front of the radiator, but I think I'm wrong. Can you confirm this ? Thanks and great video. Certainly got a like from me :)

[@MakeItEasyMechanic]

Yes, the radiator fan sucks the air from the outside into the engine bay

[@grantp4022]

@@MakeItEasyMechanic thanks for reply, so now I know. 🙂

[@carlodonnell146]

@@MakeItEasyMechanic that is correct but I wonder if it applies to all vehicles or if some push the air rather than pull

[@dylanshabtai4554]

Does the cap in the overflow bottle need to seal the air in it to create a vacuum? Can the yellow cap be opened and still operate properly?

[@MakeItEasyMechanic]

Yellow cap does not affect the vacuum, just make sure the hose from the radiator that goes to the overflow bottle goes all the way down to the bottom of the bottle.

[@carlodonnell146]

@@MakeItEasyMechanic I wondered about that too so I got a new cap for the bottle on my dodge ram

[@d.roberts7794]

How hot should the radiator be? Does it heat up only when the hot coolant goes through it?

[@2112user]

How hot depends on a number of things, including variable outside the vehicle. The coolant does heat it up, but you also have (on many cars) the trans using part of it as a cooler. Then you have residual heat to deal with in the form of direct sun light, air temp (summer heat) and heat from the air conditioning condenser. The temp of the radiator is not as important as whether or not it's cooling the fluids to the correct range.

[@ShortsAndSweater]

Trans fluid was added to my coolant resevoir. Been flushed 7 times, new radiator and hoses. New thermostat. Still overheating for 1 minute then cools back down... any suggestions ??

[@ShortsAndSweater]

Fixed by replacing the "new" thermostat. Replaced with OEM part and problem was gone

[@mvpjsj7557]

​@@ShortsAndSweater always replace part with nee OEM parts. Don't cheap out only bc it's cost less. It ends up costing you more in the long run

[@davidzornes6863]

How does the coolant go back into the radiator from the overflow cantainer ?

[@carlodonnell146]

when the engine cools it creates a vacuum and if the radiator cap is functioning correctly, the coolant will be drawn back into the radiator through the vacuum valve in the cap.

[@mohammadbader9997]

👍

[@marlonhernandez8411]

My radiator cap is releasing pressure to the atmosphere, i don't know why isn't going to the reserve thank

[@carlodonnell146]

did you check that the hose from the radiator filler neck is connected to the overflow bottle?
