It's much better in warmer climates, in colder climates, the car won't warm up or warm up really slow and will show signs of wear a little faster. If you tried this in North Dakota in winter, the car would always be in the "choke phase" and run very rich possibly wearing the piston rings out faster and you get abysmal fuel economy : /

I live in Sydney where it is mostly hot (and boring..but that's another topic). Only in older vehicles say 25 years plus I have removed the thermostat. The reason for this is to allow the old engine to heat up gradually. Heating and cooling causes expansion and contraction of metal. This then leads to metal fatigue and possible failure wear and tear. In a newer engine this is inconsequential because the metal is new. It hasn't gone through expansion and contraction often. Engines 25 years plus need help as they get older just as we will. Frequent oil changes best oil too careful driving techniques and gradual heating of the engine.
If you're driving for long distance with no thermostat, the engine will be cold and reduce fuel economy. Because the radiator is getting blasted with 120km wind with continues circulation of coolant.
Frog games is onto something So road trips yes fuel economy out the door But if u in city and stop and go at stops the engine has time to heat up a bit Anyway I like how u thought and know about the one factor a lot of people don’t bring up about this topic (the wind speed) when we driving the engine is getting cooled every second heck faster u go the cooler I did it today That sed of the goal is to keep the block cool fine Check that off But if we want our fuel to vaporize efficiently therefore not run rich and keep our part lubed in the pistons and bearings than that’s a fail I guess after researching about “is it okay to run with no therm” The answer is yes/no Yes in the city at 70sF and above No rural or road trips 70sF and above and no in the city at like 50sF and less So in my conclusion im prolly wrong Yes we found a way to beat the engineers to keep our engine block cooler but that isn’t the goal the goal is to manipulate the engines temp to run optimal and cooler isn’t the best temp is it? Lastly I think we can’t have both cool engine and efficient gas miles/lubed engine parts Fck it I’ll ask my co workers about this tomorrw at work and stay with no t stat I feel the block cooler is the way to go at least for a Honda in Tampa FL anyway it’s march now it ain’t gonna be cold till next Jan I got till next year to figure out whats wrong with the fking coolant system Amen Peace’s didn’t even watch vid just read the comments on like 4 or 5 vids there a lot wisdom in RU-vid threads Be good y’all
2001 bmw 740i, been driving it without a thermostat. The temperature needle always stays in the middle. The only difference I noticed after removing the thermostat is that it takes about 10 minutes to reach operating temp.
i think if the fan i controlled by ecu, then the engine will still heat up quickly as the fan will not be working until it gets to optimal temperature. Taking out the thermostat in this kina car, you may not notice much of a difference ..
In most cases it's 1 of 2 cases....... 1. You have a thermostat that has seized shut. Which means all the antifreeze that's being heated up can't escape... Causing hoses to burst and gaskets to fail... Or 2. You have a failing water pump. And in other cases u have a failed thermostat which caused your water pump to shit the bed (or vice versa). I suggest that if you only use your car to get to and from work on (highway miles during summer climate) remove your thermostat all together. And if by the time you park your car at your job, your car is still overheating.... Then you probably have a bad water pump. As far as cold climates go.... If you remove your thermostat....your engine will stay cold while you're driving, which isn't very good. So, I'd suggest just having a new thermo- before winter kicks in. So your engine can have the proper temp... Some mechanics will test the thermostat before installation (kinda like how you'd test one at home).Note: If you're driving on a highway and your temperature gauge is normal, but when u stop at a red light your gauge starts turning to hot.... Then you have a failing thermostat, or a failing (or already dead, pump). Or the dreaded blown head gasket. But there are also clues to determining that. Like white exhaust, or oil in your coolant or bubbly/milky oil on your dip stick.

my toyota ipsum blew a leak on the radiator... replaced the radiator and removed the thermostat. running with no problem for now and the cold engine light still goes off around the same tim as before...will replace the thermostat only if the winter seems to affect its warm up time. as for fuel efficiency in cold morning drives i can always drive economically till the cold light goes off.
Thanks for your diagram. It may help with understanding if your diagram shows a return hose returning allowing flow back to the radiator. You can't have flow with one hose.
whothecapfits the topic was the Thermostat, if the engine could work with or without, NOT how the cooling system of a car works.... pls be kind to ppl, this video is free. If you can do it better in a simple way, do it yourself. Mr. Smart pants 🙄
My Hyundai elantra 2010. I removed my thermostat 2 weeks ago it was damaged. But after every morning I check the radiator, while it's cold mind you. I get pressure pushing the cap, yet the car is ice cold and it's back pushing into the coolant tank. What is the cause? Should I put back the thermostat,? I'm not getting any white smoke or water readings from the dash. It's just water is pushing back into the coolant tank
If you live in " Cold Weather ", you will need your Heat. Basically they designed it for " On Demand " Heat, if you ask me. Here is what I do to our Trucks... I use 2 Thermostats. One, is the By-Pass. The other is " Normal ".... The By-Pass... We use it for Summer... Then we Switch it back to " Normal " in November each year. NOTE: If you do a By-Pass.... You can Drill the Hell out of the Thermostat, LOL. You will only need the " Rubber Ring " and the " Round " part of the Thermostat, so it can sit in the " Hole " safely and it won't " Leak " on you. Hope that will help People who is looking to do it.... Hmmmm, maybe I can make a Video of it, LOL
thank you for uploading such a informative video, I got my car over heated and mechanical removed thermostat. I was not having any idea why he removed and should I replace it now...got the answer... :)
Thanks for sharing the info. Please also tell that if thermostat is there but it does not get open for coolant circulation. How much riski is this issue ?
Old diesel Mercedes 1984 internal corrosion build up.....removed thermostat to compensate. Doing an acid flush risks more leaks than just removing thermostat. I live in a hot state. Optimum temp is now held going up hills and overall average driving. It no longer reaches 90% max heat risking damage to all parts of the engine. Longer morning warm ups is all.
It's over 100 every day where i live and my thermostat went out (91 toyota camry) since its an old car i just took the thermostat out. I'd replace it if you live in a cold climate though.
Thank u ! The needle witch mark the temperature goes up in less than 4 minutes wheb i turn on my car . And i replaced both the thermostat and the water pump. Im happy i came across this video .
What in a country very very hot like Nigeria, do we need thermostat? Usually I remove it because our weather here gets to 32 degrees, engines will always reach max temp.
Excellent explanation thank you... I found your video while searching for an answer to my problem... maybe you can help? I have an 89 Toyota pickup (love of my life) and it over heats when I put a Tstat in it... if course I have NO overheating problem without it but in the colder temps I'm suffering the engine is too cold problems... I put 3 brand new tstats in it and it keeps over heating!! Yes my heater is working fine... hope to hear from you soon!!
Dear friend, your truck is too old...I can bet you lunch the problem is in the water pump...you need to change it...asap..!!...this will help to recover the proper coolant flow thru the engine, hoses, radiator and the heater core as well...before installing a new water pump strongly suggest to make a radiator flush to dump all oxidation and particles in the coolant...then replace the water pump, thermostat, coolant and for the best, the accesory belt too
would it be a good idea to remove it during summer? so my engine wont run TOO hot? and have it back in winter? or should i just always leave it? my car tends to run hot during summer(never overheats)
Hi. I would like to share my view on your channel. Whether to take it or not is upto you. First of all, I would like to take the opportunity to appreciate your thought process on explaining some engineering concepts in a really simple manner. It definitely reflects on the number of subscribers that you have obtained for your channel. These are some things which you could do to make it even better. 1. Please do not take the video in one complete shot. Just by that one thing, you are unable to cut some places where you have found yourself a bit off course in explaining the things in the way you wanted them, but you are forced to continue. Believe me, cut it, take things by parts and then stitch them. You will find yourself more confident with your words in explaining it. 2. Please have some more light on your working area. Your videos are being watched by so many people now. Which means its better to have a good visual in the video. Its mostly in a shade of dark which I find it a bit dull for understanding concepts. 3. Please make sure you try to take away the Hindi-ish slang from your english. Even though the grammar is upto the mark, there are some words which I found similar to hindi words. No offense, but if you want to spread the knowledge to people around the world, its better to have a separate accent to your english which will make it even more convenient to listen to. Hope I had not offended or stirred any emotions by putting out my thoughts. The reason behind that was I usually find concepts being explained by foreign nationalities. When seeing a fellow citizen doing that, it makes me feel great. Hope you continue to make more videos and spread some interesting stuff. Cheers.
i think its good for hot weathers like 40+ degree ...... will help to reduce the overheating issues....is am i right.?.....because i tried it and it works
Thats not true i have checked my scan tool and it has no noticable difference infact during idle the fan is off until the engine gets over operating temperature and keeps it at operating temperature so thermostat are only good for idle during in snowing conditions to avoid water from freezing at the radiator as the waterpump would try to circulate icey water the thermostat would save those components on the engine by warming the coolant internally but in a warm country thermostats dont save anything
so..if I remove a thermostat to a bmw in a tropical weather, should it work fine? my question is because these cars tend to use an unique thermostat with 2 openings (for hot water in the block and the other for the cool water in the radiator)
Remove it, you'll be fine. If it becomes cooler weater and it doesnt run warm enough for heating inside vehicle then block of say a third of the front of radiator to increase the heat output/temp level
2001 toyota camry,,has no thermostat all new heat sensors new fan switch fans do not work still.. Put on manual swtch to have fan on all the time,,car temperature still getting hot. new coolant .Any idea what i can do that im missing. Thanks for your videos they do help.
Hello, I bought my Toyota Sienna 2012 without Thermostat in Nigeria. Do I need to buy thermostat. My mechanic discouraged me and saying it's not advisable
sir,,i and my friends want to learn about manufacturing processes (i.e. lathe,drilling-jig,fixtures,milling,etc.)>>> Only then will explain to diagrams..plz plz plz..
hello.. pl fix my problem...: when engine is cold .. running porly.(caanot fix axis of revolution.. it all time changing and engine turn off..when engine is warm . its fixed and runing..). when thermostat is open all time.and engine all time cold.. (opel ecotec 1.8 )
I replace the timing belt on my 96 camry. The car is running smooth, except the temperature gauge goes all the way to hot. The car is not overheating though. I replaced thermostat but it is still overheating according to gauge. I put the heater on and air comes out warm. I was thinking of removing the thermostat.
Removing the thermostat from any car isn't a good idea. It simply masks an underlying issue. Have the system pressure tested - an overheating engine could be caused by a myriad of problems - blown head gasket, cracked cylinder head / block, thermostat stuck in the shut position, a clogged radiator, inoperative cooling fan or even the wrong fuel / spark plug grade. Removing the thermostat will simply make the engine over cool, which is bad. It will increase fuel consumption, as the engine CTS (coolant temperature sensor) will assume the engine's not up to normal operating temperature, and simply inject more fuel in. This will cause premature engine wear, as the excess fuel will wash the oil from the cylinder bores (bore wash).
Not necessarily. If the underline issue has already been resolved (i.e. hose, water pump etc..), then there is no masking. Some people chose not to replace it immediately due to lack of finances or to help diagnose IF THERE ARE any further complications.. like a partially occluded heater core. Since heater cores are costly to repair, for non-mechanics, their efficiency may possibly be improved by a gently back-flush. Time/ convenience may not allow this to be done immediately. So leaving the thermostat out CAN be a good idea, for a while. As the video states, it only really effects the combustion and fuel economy, aside from taking longer for the interior heater to warm-up. Once an engine reaches normal operating temperature, it usually remain in a range near that temp, and the thermostat rarely closes beyond that point (200 - 220 degrees fahrenheit, depending on the vehicle).
if your remove termostat radiator car must clean. my car Suzuki Futura 1,500 Cc and i drive 3-4 Times a year Cross country 400 km(248 mil) and never overheat, in Indonesia if not rainy air temperature normaly 29 to 34౦c (84-93౦F)
Jason Grehawick A junker that is headed to the scraphead and has a blown-head, can many times be kept running by keeping it VERY cool. How do you do this..........removing the t-stat!!!!!!!!!!!
i am in a little situaton.ok full tune up has already been done to the car.also cleaned fuel system.the car started over heating after mechanic did mentoned that my top radiator hose was HARD.i ran a pressure test an i have 0 head gasket leaks.i remove thermostat and replaced it.car get kept over heating.so i have been running without a thermostat for almost 3 months?now i regret it baddd gas mileage on a civic 98 and went through my oil pretty fast.so can it be that i didn't bleed radiator?i did replace the radiator recently and didn't take out the air in the system.can that be the culprit?
Depends on the car. If it is an American car, the coolant runs out of the Engine into a "heater core" and then into the radiator where it is cooled by the fan then back into the engine. The "heater core" is a small radiator that is located inside the dashboard of the car on the passenger side, mounted at or around the fire wall. Connected to this heater core is a blower fan and motor. This is designed for warmth in the winter time. You simply turn your air condition setting to heat and set the fan to the heat output you want and your cab stays warm. The heater core is, generally - like your radiator, made out of copper. Over time the copper becomes corroded and forms a leak. This makes it's way into the floorboard of the vehicle on the passenger side. You have 2 choices now. Remove and replace the heater core or cut the hoses going into and out of your fire wall from your block and to the radiator, respectively, and bypass heating system with a double male adaptor that links the 2 hoses and allows the coolant flow to continue. This method is cheap and quick, but you will regret doing it when winter hits and you have no way to defrost your windows or stay warm in the cab. If you do nothing eventually the leak will grow and you will have not only a stinky cab but an overheating vehicle.
I have removed thermostat (Nissan sunny 2005 Dubai)as the engine was overheating, I have replaced the radiator as guided by a mechanic. He recommended that to remove the thermostat, in order to avoid overheating. I hope that there will not be any problem because of this. Please advise thanks & Regards Shaji
shaji kalpetta my car was overheating all the time, replaced thermostat twice, same result, removed it, problem solved, specially when you live in a hot area, thermostats are for cold countries like Canada or Rusia
thermostats are great for up climate whether but here in Miami we don't need them it gets hot all on it own and very quickly and extending the life of the engine. why are all cars geared for winter climates?
i am in miami too.i was running a 98 civic with thermostat and one day the needle when to the top.radiator was just replaced,full tune up and cleaned fuel system.you meant to tell me it's okay to run wthout a thermostat for a long period of time?it does take forever to get to normal operating temp and my gas economy is not doing well.or that might just be me.
Hie I have Honda civic 2007 model automatic transmission ...i changed the thermostat valve but when ever i drive in sports mode my engine gets overheat , i checked with Honda service center they said replace the radiator its gonna cost me 25k ... Plz do help me why my engine getting overheat while driving in sports mode .. I will be very thank full to you ...
Hi bro,I m in civil engineer we have rig machine in our site this machine engine frequently getting overheat so, my question is without thermostat we can keep optimum temperature or not if it's then how it ll be working can you explain
If you are an engineer like you said you must be capable to solve this by your own...run some tests on the rig with and without the thermostat...chart your readings and decide accordingly.
MIKE GUILAS they use alot of sensors simply to monitor engine parameters which helps the engine to be more efficient. Now adays you can never achieve the best ot of the engine without electronics. Sensors only cause problems the time they reach their working life. And electronic parts is easier to replace than mechanical parts but with a cost.
my car overheated, then shut off and now wont start. someone suggested that it might be a failed thermostat. will a failed (inoperative)thermostat prevent engine from starting? thanks
its ok, but u will burn more fuel, that means low on millage and low on power, because optimum temperature is very important for proper combustion of fuel for power creation.
I am a subscriber and a fan of techtrix videos , but, you guys need to have better videos . Use multiple cameras , mayb another host , and please stick to more detailed gfx diagrams. Bring better editing and lighting for a videos and when talking abt a device .try to get one of tat n show it to the camer , this video here is informative but boring . I mean you guys just tot one evening ''hey let's just make a video about thermostat . Buddy take the cam. Let's do this ''
hi, recently I changed my radiator as it had cracked when my car pounded on a porthole.... post then I frequently check my engine for any abnormalities... I m not well knowledged guy abt engine... just wanted to know that #when I start my car after 5 -10 mins I check the upper hose coming from the engine to radiator to be hot while the lower hose connected frm radiator to engine is cold.... #I see no change in my temperature gauge as it stays between hot n cold.... # when I go for a ride say 15-20 km n after returning I check my radiator it is pressurised but after few hours when the engine is cold it is not pressurised and coolent level is gone down around 150-200 ml... Is this normal? se times I see coolent overflowing from reserve tank then I have to top it up... Is this a thermostat problem or some thing else...
1st u told with out thermostat means the metal will be expanded because high temp..... the water is circulating inside the engine then how engine got high temp..... how is possible....?
+Jagadeesh Raj 1st) there is exchange of water/coolant between engine and radiator, hot water from around the engine flows to radiator, cool water/coolant from radiator flows to engine. Then the hot water in radiator now cools when heat is exchanged between radiator and atmosphere. So now if thermostat is closed Hot water stays around the engine and will damage gasket and any non metal parts. Forget about melting metal, that won't happen.
