I say no, every single car I’ve ever owned and I live in Los Angeles the first thing I do is rip the thermostat out , newest car I’ve had was a 2017 Hyundai sonata, my Uber car, and I pulled the thermostat out. oldest I’ve had 1984 Chevy K5 blazer diesel no thermostat, my 1992 Chevy 2500. I ran it for five years with no thermostat, hauled countless loads of tile, 2 tons at a time, and towed many trailers with dirt, bikes, and camping gear along with my truck being full never overheated, and it still has not given me any problems. In fact, it’s better for my vehicles. I don’t know why maybe the climate I’m just telling you my experience. My opinion when you close off the water flow that’s bad for the water pump because the water pump is working overtime to try and pump water through a closed system. If you remove that thermostat and open everything up, there’s no resistance and it saves your water pump and keeps the water free flowing now if you’re in a climate, that’s freezing cold or even blistering hot that’s where you’re gonna need a thermostat. Other vehicles I’ve done this with include, 98 accent, 88 and 92 Nissan hardbody,89 s10 pickup, 02 tundra, 02 accent, 92 FZR600r, 94 zxr750r, 07 fjr1300r , none of these ever gave me any overheating problems after removing the thermostat.

The only problems I ever had with thermostats, one stuck closed, another the middle section that opens and closes actually broke out somehow so it was just a restrictor hole for coolant flow.

Thank you sir

Running an engine without a thermostat can make the engine run hot or overheat. Nearly all modern engines require the lower half of the thermostat to close the bypass and heater side of things as the engine gets up to temperature. If this port is not closed or restricted, a large amount of the coolant flow will not be pushed into the radiator for cooling. The water will recirculate within the engine getting hotter because the water is not forcefully flowing through the radiator. As a result the radiator will appear to be cool but the coolant within the engine can be high. You might have got away with that sort of hack 50 or more years ago with the very simple thermostats but not nowadays. I have also seen old systems without thermostats overheat on hot days because the coolant was simply flowing too fast through the radiator to cool properly. I used to modify radiator tanks with baffles to make the coolant pass through more of the radiator cores. And as far as thermostats controlling the engines coolant temperature, you are correct that it controls the minimum water temperature but it also regulates the flow of coolant of which controls the coolant temperature over a range of engine power output. The thermostat starts to open at the minimum temperature, it does not spring fully open. The thermostat modulates the flow of coolant through the cooling system and in turn keeps the temperature at a reasonably fixed temperature with varying power levels until the thermostat is fully open. When fully open, the temperature will continue to rise because cooling capacity limit has been reached and with more power comes more heat. The radiator has become heat soaked and unless more airflow or cooler ambient air or less power is commanded, the temperature will keep rising with more power. The whole system is engineered to be suitable for the vehicle it was designed for and any overheating issues means there is a problem with the system. If there is no problem with the cooling system, then it will be an engine or transmission problem or the vehicle has been modified or the vehicle is being operated outside the design parameters it was designed for. So, yes the thermostat does control the engine coolant temperature and is critical in making the engine run to comply with air emissions. A colder thermostat will make the normal running of the engine lower providing the heat can be removed by the radiator properly.

@@robertjahrling1877 G'day Robert, The radiator tanks were removed from the core and I used to manufacture brass baffles to the same inside section of the upper and lower tanks and solder them in to the tanks. I would generally divide the core into thirds or quarters depending on the job. I would set them up so that the first baffle was placed 1/3 or 1/4 of the top radiator tank so the coolant would pass through the 1st section of the tank and then be pushed through to the lower tank. Then I would put another baffle in the lower tank 1/3 or 1/4 along the lower tank so the coolant would be pushed through the next section of the core and repeat this process . The end result is the coolant will be pushed through 100% of the core forcefully and rapidly cooling down with each pass. This is a Superior way of making the available surface area and capacity of the radiator more effective. A std radiator configuration will push most of the coolant through the first 1/3 to 1/2 of the top tank and the rest of the radiator will not be as efficient as it could be . This mod I used to do was mainly for industrial and stationary engines , gensets and drill rigs in out in the Australian out back where temperatures exceed 45 deg for months at a time. I also used to do a lot of 4x4's especially after they have had major power enhancements or engine swaps. It was a great mod for 4x4's that had these changes and could not install larger radiators because of space and or aesthetics constraints.

Had a Ford 4 cylinder about 84 Escort. 2 cylinders weren't getting enough coolant. Warped and cracked head. The fix was the replacement head gasket restricted the flow making the coolant spread out and cool all 4 cylinders.

I used to own a 1979 Oldsmobile Cutlass Calais 5.0 V8 and it blew a heater hose the third day I had the car operating. I replaced the hose clamps with screw style clamps, the hoses to high performance heater hoses. When I went to swap the radiator hoses I checked and there no thermostat. So I installed a 190°f thermostat. The car never overheated and boiled over again. The coolant before and after the repairs was brand new.

I had a Mercedes 300TE (3L straight 6 cyl) which needed a new waterpump because of leaking seals. It never overheated even on hot days in the tropics. I had the waterpump replaced and had a horrendous overheat problem within 20 minutes of driving. This problem was caused by the mechanic removing my perfectly working thermostat. So YES! It can cause overheat. The reason was no water back pressure at the thermostat which severely reduced water flow to the rear cylinders which caused coolant there to boil and dump the coolant out the radiator cap! A new thermostat fixed this immediately. However one year later my head gasket failed due to this. Some engines need the thermostat in for normal ops and be very cautious about running without it. Other engines are ok.

Any liquid-cooled car engine has a small device called the thermostat that sits between the engine and the radiator. The thermostat in most vehicles are about 2 inches (5 cm) in diameter. Its job is to block the flow of coolant to the radiator until the engine has warmed up. Once the engine reaches its operating temperature (generally about 200 degrees F, 95 degrees C), the thermostat opens. By letting the thermostat open, it lets the antifreeze flow back into the radiator as the cooler antifreeze goes into the block to keep it cool. The thermostat reduces engine wear, deposits and emissions. Different vehicle does not have a thermostat the antifreeze overflow and heat up in the radiator and block. 🤔

Thank you

In the hot climate country, OK for thermostat removal since electric cooling fan is always on assisting cooling process. Thermostat removal to be follow by plugging the bypass line, if not then 50% coolant flow through radiator and other 50% through bypass line. This the common mistake for just remove the thermostat.

Does the thermostat have anything to do with the amount of pressure in the cooling system? Both coolant lines on my 03 Impala (3.8l) seem to have more pressure building up during normal operating temperature.

The Jeep JK OEM thermostat opens at 95 celsius while most of them in my country are operating at engine temperature above that, if you go up hill or offroad the heat will increase so we remove the thermostat which keeps the temperature stable and never over heats.

Tried a lower temp stat and temp guage is much lower all the time.....bought a higher temp one now its just right.

Instead of closed or open, can a thermostat be slow to open? And it's intermittent. Sometimes from a cold start it will warm to almost red before dropping back down to the mid mark - then its fine till the next cold start. I've had to pull over and stop twice to let it cool off.

If your overheating on a stock engine the thermostat could cause it if it's not opening or not all the way open but usually you have an other problem like air in the system or a blockage in the coolant system.

I took the thermostat out of an overheated car that I bought for almost nothing hoping it was just that. It wasn't.

Had I not taken it out, I would have stranded within 10 minutes. Roadside assistance got me the last 10 miles.

I disagree on a couple of points. I feel this is oversimplified. Thermostats do restrict fluid flow even when full open. Coolant temperature depends on multiple things, not just the thermostat. The amount of air across the radiator has a great deal to do with coolant temperature reentering the engine. If there is adequate airflow and proper coolant flow, a 160 degree thermostat will maintain that temperature regardless of engine load.

Thermostats also get stuck closed. We're experiencing a new thermostat that opens later than the stock one, and the car starts to overheat before it does open. The thermostat does control coolant flow through the radiator and if it's staying closed, it's not being cooled down in time to cool the engine before the coolant begins to boil and escapes via the overflow.

@jgmopar. Wrong. Faster moving coolant picks less heat in the engine too but returns sooner for more heat. The same with the radiator. Faster moving coolant returns sooner to dissipate heat again. Coolant speed, slow or fast, over all, removes the same total amount of heat in given amount of time. Also coolant flowing so fast that it creates a space or vacuum between the coolant and metal surfaces caused by speed is highly unlikely especially in a pressurized environment. The coolant would have to be traveling at an extreme speed.

I have an subaru that is blowing exhaust out of the head gaskets into the coolant and it overheats right away. But there is no heat in the car. Person told me pull the thermostat the car is overheating before the thermostat can open. He said I won't have heat inside the car but the car won't overheat from the exhaust gases.

So question is it ok to take out my thermostat for just a few days? I have a 2011 Camaro lt. my fan works but my cat is running hot

Take it out, will increase power as when engine running cooler it fire more and have your fans run full time.. that the best thing if u want to race. Vehicle won’t overhead which equal to run race all day and safer for your gasket

in tropical countries cold start is no big deal... running your engine without a thermostat is good.

but it work with my e30 m40, suddenly overheat just like a broken thermostat or weak viscos, change new radiator, new water pump, new viscos and new electric fan, but still overheat, never thought its because im not using thermostat but when i put a new thermostat in it its all good just like that, still dont get it till now

Your thermostat can also stick closed which means it never allows apporpriate coolant to circulate.

My dad's 1992 Nissan pathfinder XE is not overheating and it doesn't have a thermostat either

Did you not watch the whole video? Your dads car won't over heat if he dosen't have one, but it will run less effectively (mostly because all gas engines need a little bit of combustion help other than a spark plug), if there is no thermostat you will spend more money on fuel because it takes more stress in the cylinders to get the engine up to its general operating temperature. Engines run better at certain temperatures with certain amount of gas to air ratios. Cold weather needs a different fuel to air mixture than warm weather does. The thermostat will not effect the engines running temperature, but the engines running temperature will effect the wear and tear or fuel economy of the engine. If you live in a southern state, like tx, no big deal if you pull it out. Minnesota in the winter? The engine engine has a hard time getting the right fuel to air ratio.

I have a 1997 Okdsmobile Aurora that was overheating badly. I went to replace the thermostat and found there was none. So i put a thermostat in and it has not overheated since

@@DarkLinkAD Other than opening and closing at a certain temperature, please explain how it "regulates" coolant temperature. It allows coolant to warm up quickly to a specific temperature, then opens so the the coolant can flow through the system. If that's what you mean by regulate then sure, you're correct. Tell me what the thermostat does when the coolant reaches 230*? Please explain step by step what it does at that point. Also explain how the thermostat allowed the coolant to reach 230* in the first place since you say it regulates it.

You move the goal post, you devalue said argument. "I paid for sky blue" " The sky isnt really blue, because blue is only a refraction of light, so I thats why I gave you primer white" Wizard speak.. Oh, a thermostat is literally a diaphragm that expands with resistance to a spring, designed to do so at a given temperature. In a PROPERLY engine, the thermostat will open slowly at 180 degrees(typically), hot coolant will pass into the radiator, ambient coolant will continue through the pump, block, heads, throttlebody etc until making its way back to the thermostat... What would a thermostat do in 230F engine? It would stay open, because something else is broken/cracked/malfunctioning entirely, this is you moving the goal post.

Lol, clearly you don't pay attention to your car while sitting in traffic. It'll reach 230 no problem, fan kicks on and it cools off. Doesn't mean the car is broken. Diagram opens, yes, then what? It stays open and coolant flows around the parts as you mentioned. During acceleration, said parts are getting hotter and as such, the coolant gets hotter and the system can only dissipate heat so fast. When you're sitting still, no air is not flowing, so heat exchanging is limited, that's why when you're sitting still and the fan kicks on, that the coolant temp drops, because the fan is moving air, allowing heat exchange. Nothing to do with the thermostat. no wizard talk, as you say, simply just how it is. I'm sorry that you're confusing your cars thermostat with your house thermostat. Install an obd2 reader and use an app such as torque and actually watch your temps fluctuate as you drive and sit in traffic. Temp gauges have a dead spot which will range from 180 to 240 where the needle (or block depending on your dash) so it doesn't look like the coolant temp is changing, but it is. That's just how cars work.

Hello, my question is… my son traded his 04 F150 for a Honda Civic. He has it for about 4 days before it began overheating. We figured let’s start by checking the thermostat. So I go to swap it out, I get the thermostat housing off and “voila” there was no thermostat in there at all. Swapped it out drive around for a good while and so far engine temp has been in the middle of the gauge. Why would anyone remove the thrmstt.

Today I was sitting on horrible 1 hour traffic and later but everything was alright until later when and I noticed my car was about to over Heat so I pulled over turn it off for 30mins and I checked my car and it was even hot how weird then waited a bite then turned it back and the level went back how its supposed to be.. Then I drove it normally..

Stuck on traffic means no wind coming in from the front and the radiator won't cool. Your fan might not be working properly or your radiator is clogged.

the hose harden but temperature gauge will be at operational temperature .is this okay

Replace the hose, hardening is a precursor to leaking.

I took off my thermostat on my Jeep Cherokee and it don't heat up no more.. We are in cold weather right now now the check engine light came out and it says check gauges and the temperature one it stays at low the whole time and it makes this noise in the engine like it needs air or something like forced to drive sound?

YESY RODRIGUEZ if your vehicle is overheating with it in!! Then you have a problem!!! Weak water pump! Leak/, in whipping hole gasket radiator!!! Cussing air into your system, try blue devil!! Gauge will stay at low because fluid is staying cool engine isn’t meeting temp and temp sensor is sending mix signals to pcm!! The noise!! Is your water pump gone bad!!!

We’ll the thermostat also restricts flow so the coolant can absorb heat. If you have no thermostat the coolant won’t have enough time to absorb the heat from the engine and therefore on long drives you will overheat

that entirely depends on the climate of your location, if you're driving in warm and tropical climate places then you dont really need the thermostat because the coolant temperature is constantly fix on the optimal running temp level, but if you're driving in colder climate and snow then you definitely need the thermostat in order for the coolant to melt in radiator before going in to engine...

so if my 2001 toyota camry .that i replace three fan sensors and fan switch still no fan kick on so put on manual toggle on all the time now but still temperature getting hot. head gasket good fresh new coolant..and i took off thermostat. still getting hot. coolant is flowing ,i dont understand. can you help..before i have to take to shop..Thanks for videos..they help alot.

Update

Thank you. Just bought a 95 Tacoma 4 cyl. Started overheating when it was idling fir 4 minutes or so. Guy I bought it from says the thermostat is old and never replaced and it’s probably shut closed and that is why. Not sure how the fan works but it is spinning when engine is running. Is this true and can I flush it and run it without the thermostat just for a vew days untill I get the thermostat. Thank you.

I just added a fan Stroud and it instantly fix the problem 😂

I have to add my input on this and I believe that running without a thermostat is a bad idea because number one the water is just going to pass through the engine to quickly without absorbing the heat like it’s meant to in other words it can create hotspots in the cylinder head without reflecting on the overall coolant temperature so in my opinion it is a bad idea to run without a thermostat or some sort of Restriction at the minimum. Also it is a bad idea to block off bypass ports because those are needed for correct thermostat operation to have some water circulation while the thermostat is closed Removing thermostat may allow the engine to run slightly cooler but that all depends on the cooling capacity of the radiator let’s say for instance do you normally run a 190 thermostat and your car runs at 210° well removing thermostat isn’t going to change anything it’s just going to take longer to warm up but it’s still going to run at 210° but if you were able to add let’s say a second radiator you’re going to increase your cooling capacity so it could in theory run at I don’t know 160° but like the guy said thermostat allows you to run at only minimum temperature.

Exactly right. These people believe a lower temp thermostat can magically bring the engine temp down just because it opens earlier. That's some bad logic. the opening temperature is ultimately irrelevant if the engine reaches normal temps. That's like thinking that on a carnival ride, lowering the "you must be this tall" sign's arrow, will make tall people shorter. It's just as ridiculous. for a thermostat to have an effect, like you mention, the engine must suffer from overcooling, not overheating.
