That “trick” might work great in Texas, but if I went through all that misery to get at that thermostat, I’d put a new one in. If it does overheat after that, I can rule the thermostat out, because it’s new. I don’t really hold with this “repair”, because we need working thermostats here in northern Minnesota.
I live about an hour from Scotty. Trust me.. It's rare we ever hit freezing in winter. It's already been in the 100's this month. This far south, thermostats are optional. You don't want restrictions in your cooling system while in bumper to bumper traffic during summertime driving in Houston..
SK-a Toyotas best friend! Picked up a '98 camry from scrapyard. The guy said overheated and shop told him $800 water pump job so he scrapped it. I threw a $15 coolant temp sensor at it and wouldn't you know my daughter has been driving it ever since!! Thanks Scotty for your vids😎👍
Love your videos. I'm a retired diesel mechanic after 47 years. So many changes as you have experienced over the years. But one thing that still relevant is common sense. Thanks.
Hey Scotty, I had the exact same car with over 350,000 Miles. It still ran quite well. Engine was perfect, Transmission still shifted like new. This car doesn't look like it was taken care of.
When you took the thermostat housing off green coolant came out. You replaced it with pick coolant. May wanna let the guy know that he had the wrong coolant in the engine.
A used '95 Corolla I bought already had the thermostat removed from the previous owner. The car took a while to warm up and never got to proper running temp. Because it took so long to warm up, if I left home before the temp got to a certain level, the car wouldn't shift into OD (or the converter wouldn't lock up, one of those). Come to find out, the radiator was 50% clogged with plaque. Changed the radiator AND the thermostat, and it was good to go.
I have driven three Silverados over the last 20 years. Last year I bought my first Toyota, a 2019 V6 Tacoma. I have put 48k miles on it and I just love this little truck! The 21 mpg is awesome, too!
If I was going all through the effort of removing the thermostat I'd put a new one in before I did it all back up again! Then I'd know it was good and not have to mess with it again, regardless of the test results.
YES, For sure on a cheap part for an old car just put a new thermo in, prob fix it if not no big loss and besides you know it thermo wont fail while you have the car.
1 hour charge to remove and run, or 2 hour job to go to the store and replace with a new one. Money's tight for the owner, or they would have fixed it 6 months ago.
When I was a young mechanic in northern Australia we often removed the thermostat on cars even new ones but but was like you say on old cars these where back in the 70's and 80's ..... worked well
Lol I was thinking the same thing. I can get one at my local auto parts store for $5.53... Did I miss the part where he explains WHY he didn't put a new one in?
Well youll know for damn sure if it does overheat it has 0 to do with a thermostat which i think is the end goal here. I dont think theyll leave it like that but to rule out the thermostat this will work.
My '90 Lumina 3.1 had a stuck OPEN thermostat. It wouldn't warm up enough for the overdrive to kick in on the highway. Here in Ontario, you need to run a thermostat. Otherwise, you get no heat in the winter! BRRRRR! LOL!
Beside that, your system needs to be under pressure. Yes, Ontario can be cold but, what I dislike the most is, the amount of humidity. Well, in Eastern Ontario to be more precise.
I live in Marlin TX, have also left out thermostat AND modified radiator caps to hold no ( 0 ) pressure on old vehicles. Get flow and cooling, but no leaks.
New ones can be defective. Even new ones individually tested to work as designed can fail at any time. The only really foolproof mod is a manually operated shutter in front of the radiator. Some ancient SAAB cars had that design.
@@stephenarling1667 well this isnt a Something thats Always, ALWAYS Breaking car. This is a Toyota. And one of the best Toyotas. Their components generaly are far more robust.
I really don't agree with this *fix* Scotty suggests. Thermostats are cheap and highly reliable. They rarely fail and usually outlive the car. Running without a thermostat isn't good for the engine because the engine gets full coolant flow from the moment it starts until the car is shut off. That keeps the engine from ever fully warming up, and Scotty is one of the first people to tell you that's important. It can affect fuel economy, engine performance, even engine longevity.
Toyota redesigned the Camry for the 1997 model year and made many improvements. It beat out the Ford Taurus as the #1 selling car. As you can, see it is reliable and last a long time
I'm glad somewhere else caught that. I had to rewatch it just to ensure that my eyesight wasn't going out, because I knew I saw green come out of that bad boy.
I think the car was to old to have the newer pink coolant. I bet Scotty did a drain and refill with more modern coolant. He just edited that part out. I had a 80s Silverado that I rebuild. It had the green coolant after the rebuild, I put in the newer orange coolant. It's just better with all the newer anti corrosive properties.
@@seanC3i The additives can bond together making it sludge up over time. You can mix green and orange coolant but not Toyota pink. I forget all the technical names of the difference between all three.
PSA: If you want a new gen mustang 2015-2017 have V6s but you have to get them used. Best value option. Ford were idiots and discontinued the V6 in the new gen mustangs. The V6 is cheaper than the 4 liter ecoboost and lasts probably double the miles.
When the dual mass flywheel went out of sync and caused the bores to flood the engine on my 2010 Seat Leon FR 2.0L tdi 100k miles. I got rid and ... I got a 2015 Honda Tourer 1.8L 36k miles. Slower but will serve us well. Thanks Scotty 👍
My newer Corolla (purchased new in 2012) has had a bad compressor almost since new. I noticed it in first few years but it was too inconsistent to get it dealt with under warranty. About one in four times you use it you get hot air until you hit a bump in the road or something and it suddenly comes out cold. So, yeah, the Corolla's compressor seizes about 25% of the time. Same thing happens with the blower motor in my brother's 2013 Chevy Volt though his can often be kicked by a passenger to get it going (right under/behind the glove box). I've honestly thought about rigging up a renote-controlled solenoid for both of us to give them a deliberate knock when you need it.
I did the same kludge fix for the thermostat on a 2000 Acura a couple springs ago, because the engine kept overheating. Solved all my problems... that is until November. Minnesota in November tends to get a bit too cold to drive around without a functional thermostat. After putting in a NEW one, I wished I just spent a few dollars for a new thermostat the first time around instead of screwing around under the hood a second time.
I ruined an engine running it without a thermostat. I learned in 1989 that if u run a car in the heat without a thermostat. That it increases the flow so much that the coolent didn't have a enough time in the radiator to cool and eventually on a hot day it will overheat where if it had a thermostat it wouldn't have.
The Dodge Dart was discontinued after the 2016 model year. There were several reasons why it sold poorly. Although their infotainment system looks better then Toyota's and it had a few features not available the Corolla
Thanks Scotty! You saved me again! One of my car has its thermostat stuck on open. Whew! My second car wasn't so lucky, and it was stuck on closed suddenly on a hot day. Radiator got shot. 50/50 gamble I would not take again.
My 88' Camry was running too cool, in the winter, froze when you drove it. $19 thermostat Autozone, has a safety overheat check valve to keep thermostat wide open when running hot., but mines the 4 cyc. easy replacement, right next o the oil filter! Runs fine warm in the winter cool in the summer!
Also the bottom hose can collapse because it gets weaken because the wear and time passing by! Had that problem with 87 Supra, changed radiator cap, thermostat, solenoid that controls the fans, changed upper hose and finally when I changed the lower hose it worked like a charm! It would only overheat at high speeds! At low regular speed all ok!
I took all the thermostats out in my 3 cars. They are all 30+ years old. Where I live the air temperature rarely goes below 60° so all a thermostat will do is restrict coolant flow during the 90% of the year when the air temperature is 80° and up.
Some people freak out with scotty hand movement. I like😂 because I do it too and a lot. It's just intuitive, especially when I try to explain something to someone.
Give Scotty a break - He was born and raised (I believe) in the Niagara Falls /Buffalo area of Western New York - a place that is heavily populated by Italian Americans,most of whom speak and describe things with a lot of hand gestures, as Scotty does - let him be - he's too old to change...😂😂😂
We had a trick, if you are on the road, depending on the car. You can take off the radiator hose, leading to the thermostat, and using a screwdriver and hammer punch a hole in the thermostat to let the fluid go through. Be careful not to break anything else and get it fixed as soon as possible!
My 04 Corolla stater acted up like needed a new one. All it was was the switch on cluch pedal that allows it to start. All mechanic did was clean it with wd40 and adust it a little. No problem after that a cheap fix for sure $20.
It looks like it's getting hot in Houston. This reminds me that I should probably replace the thermostat in my vehicles this summer before they give up the ghost on me. They've all been in there for several years now.
I guess I'm the minority who rides his motorcycle to work and back. But I can testify that besides chains, sprockets, and tires. You'll usually only find new parts for your specific motorcycle at a dealership.
My 98 Camry that had 330K miles on it had a thermostat issue once...it stuck OPEN. Did not notice until winter when it was fine on temp when at idle, but when you started moving the temp would DROP.....not fun.
Radiator cap itself is a likely culprit. Just about lost my mind trying to track a coolant "leak" on my Odyssey and it turned out it was the radiator cap. If the car overheats due to low coolant, test for leaks. If you can't find any, or you hear hissing coming from the cap, it's the cap that needs replacing. And they do go bad after a while. And be sure to buy proper OEM parts, I made the mistake of buying a cheap cap and thermostat, both of which failed prematurely.
Story time: I had an F-150. It would only overheat when it was freezing (32F, 0C). It never over heat during the summertime. I replaced the thermostat (nothing), radiator (nothing), hoses (nothing), cabin heater (nothing), coolant (nothing). It would still overheat during the winter. I didn't see any leakage from the water pump and never lost coolant (except during the wintertime when it overheated. On a whim I decided to have the water pump replaced. I found out this Ford designed their impeller on their water pump to be a disk with blades riveted on. The rivets were still there but the blades had worn down to nothing. For some odd reason it would still move coolant enough when it was hot outside but couldn't create enough pressure during the wintertime to push the coolant. Since it would only happen in the wintertime it took me about five years to track the issue down. I'd replace a part and it would seem to work fine, but come next winter I'd have to replace something else.
Always put a rag over the positive terminal on the battery, especially an exposed terminal. A young mechanic I worked with accidentally touched his wrench between the positive and negative posts and the battery went boom. He had to shower for 15 mins before going to the emergency room, but luckily acid burns. How to wear out an old engine faster or cause the head gasket to fail: take out the thermostat and don't replace it. Having said that, I've had brand new thermostats fail the odd time, so I guess Scotty simply removing it was ruling it out as the problem and will replace it later.
Sometimes they really bury the thermostat and housing and can make it a real fight to get to it. The easiest one I have ever done was on a 1978 Cadillac Coupe De Ville. Right on top and 5 to 10 mins.
Speaking of starter problems... Let me throw this one out to you - it will take a bit. Bought a 1998 Chevy Monte Carlo in 2002. Later that year it was hit in the front drivers side fender at a 90 degree angle. Car got fixed but AC went out about a year later. I refilled the AC coolant but it leaked out within a week. Said screw it, let it be. Still had the car about 5 years later. I started getting an intermittent burning rubber smell from the engine - couldn't figure it out. Then one day I went to a store and when I came out the car wouldn't start. It sounded like a bad battery, you know that rar, rar, rar sound. Called AAA. Tow truck came, and told me my battery was good. Towed me home. Took the battery out, charged overnight and put back in the car - same thing, won't start sounds like battery. Pulled Alternator. Went to... I think Auto Zone, and had it tested. Worked fine. Won't start.... ??? Starter? Pulled out the starter, had it tested - worked fine. Now what ???? Just for the heck of it I put everything back on and took off the belt - I was guessing at this point. Car started right up! What was it? The AC Motor had seized up! Locked up, wouldn't move. The burning rubber smell was the belt sliding across the AC Motor. Then one day enough rubber built up, like on a racetrack, and everything seized up. Found out you could replace the AC Motor with a pulley. Did that, car ran fine - with no AC of course :(
Cutting out the thermostat will not be nearly as missed in Texas (the southern states) as it would higher north, where you need to it help warm up the car for your heater on cold days.
You don't want to drive a car without a thermostat. The engine will never get to regular working temperature, and most importantly, your oil will never go over 100 degrees C, so water will start to build up in the lubricant. Eventually, enough will develop and it will destroy the main bearings.....
That's good to know about the expensive parts for motorcycles. Not knowing that when making a major purchase like that could really bite you in the butt down the road.
If, after removing your car's thermostat, if your car's computer does not complain and your car runs just fine, well... depending on where you live, you can still have a problem. When the winter arrives, your car's heat will not warm you up. At best, it might blow lukewarm. On a cold day, you can forget about having a warm cabin. Also, your gas mileage might suffer a bit.
My thermostat stuck open in the winter. I would freeze going to work, by the time I get to work heat would just start. This was my first experience with engine trouble as a 16 year old.
Since you spent all that time taking the thermostat off and, if I am the car's owner, I would just spent $30 more and get a new one to put it back on regardless what the problem might be - at least there would be a new thermostat is installed.
Scotty says Toyota Coolant is pink. Of course, when he pops the thermostat housing off, a big gush of green coolant flows out. Hmm,...maybe we figured out the problem?
Thermostat is a on off switch. Switch opens when fluid in motor gets to hot. Hot fluid moves to radiator to cool, cool fluid moves to motor cools it off and thermostat switch closes. Hot fluid in radiator cools off, cool fluid in motor heats up and thermostat switch opens again. If no switch hot fluid does not stop to cool off in radiator, car overheats.
I don’t even like cars that much but when I’m stressed I watch scotty and I just drift off into scotty wonderland where there’s Toyotas and endless money pits! 😁
Stuck thermostat can be real bad news. Knew a guy that had a Pontiac T34. Really nice car that he bought used. Didn't worry about the temperature. Ruined the engine. Today even in that condition the car would be worth a lot. Back in the early 1980s, not so much. Dime a dozen and was scrapped.
I had this problem twice in my honda one time it was just low coolant. Another time there was an air bubble in coolant so my sensor was not turning my fans on properly. But these hondas 4 cylinders run so cool that I was driving around without coolant for probably 2 months and my car never overheated until I left it running outside my house parked for an half hr one day.
I've never thought about using plastic as a wedge when using my sockets. You've probably just saved me 10 years of my life cussing and cursing all while trying to figure out where the dang bolt/nut fell to.
I would not do that thermostat trick anywhere with cold or even cool weather (again). Did this on an old Ford and it wore out pretty quick. That and the 20-50w. Bad during cold starts and you will never have heat in the winter.
Instead of completely removing the Thermostat, you can also replace with one that opens up at lower temperature. That way the engine can still warms up in the winter. Good for the engine. That's what I did to my corolla, aha~~~~
actually, the copper barrel of a thermostat is full of wax. the wax expands when it gets hot and squeezes on the conical-shaped pin that runs through the barrel. a thermostat fails when the wax looses its ability to expand. the spring has nothing to do with the failure. the thermostat fell apart in my 1995 ranger and allowed too much flow. it tripped a code 'engine temp too low'. so even back in 95 it tripped the code. i recommend to ALWAYS replace the thermostat. never leave a thermostat out.
I thought you were going to say "never set down your 10mm socket" I'm convinced there is a black hole out there full of them. This last time they got my 1/4" drive too but probably only because it had a 10mm on it.

Thanks Scotty! You saved me again! One of my car has its thermostat stuck on open. Whew! My second car wasn't so lucky, and it was stuck on closed suddenly on a hot day. Radiator got shot. 50/50 gamble I would not take again.
Hello Scotty! I have the same car with 377,000kms with no issue. Thanks Scotty!
hello!
Dude that trick with the plastic for holding the nut in.......that's totally clutch!! Awesome.
My 88' Camry was running too cool, in the winter, froze when you drove it. $19 thermostat Autozone, has a safety overheat check valve to keep thermostat wide open when running hot., but mines the 4 cyc. easy replacement, right next o the oil filter! Runs fine warm in the winter cool in the summer!
If you run an engine without a thermostat the engine will fill with sludge because the oil will not get hot enough.
Also the bottom hose can collapse because it gets weaken because the wear and time passing by! Had that problem with 87 Supra, changed radiator cap, thermostat, solenoid that controls the fans, changed upper hose and finally when I changed the lower hose it worked like a charm! It would only overheat at high speeds! At low regular speed all ok!
To keep my Toyota from over heating all the time. I just went out and bought another used Toyota . Thanks for the advise Scotty
1mzfe-that engine is a beast. My 99 Avalon still going with 349k miles. Easy
I took all the thermostats out in my 3 cars. They are all 30+ years old. Where I live the air temperature rarely goes below 60° so all a thermostat will do is restrict coolant flow during the 90% of the year when the air temperature is 80° and up.
Some people freak out with scotty hand movement. I like😂 because I do it too and a lot. It's just intuitive, especially when I try to explain something to someone.
Plus, it is a sign of honesty
Well he's a mechanic, he can't stop his hands. 😁
Give Scotty a break - He was born and raised (I believe) in the Niagara Falls /Buffalo area of Western New York - a place that is heavily populated by Italian Americans,most of whom speak and describe things with a lot of hand gestures, as Scotty does - let him be - he's too old to change...😂😂😂
@@frankgiaquinto1571 Yeah we know. He likes our razzin
Oh damn. Thats a 97 ish Camry. One of the best they ever made.
I have that same one.
Don't neglect it like that :(
I've been doing the no thermostat thing for years! Great video
If your in Florida, you don't need a thermostat. Always hot here!
@@applepoop10 no, I'm in southern California. (L.A.) I wouldn't mind beautiful Florida's weather! 👍
We had a trick, if you are on the road, depending on the car. You can take off the radiator hose, leading to the thermostat, and using a screwdriver and hammer punch a hole in the thermostat to let the fluid go through.
Be careful not to break anything else and get it fixed as soon as possible!
I would have bought another thermostat as they are not that expensive, but thank you for confirming any doubts.
I am gonna try Scotty's trick using a thin piece of plastic wrap with my sockets. It looked good in his video.
A rubber band works pretty good,too.
I've used paper before, also a leaf if I'm outside.
Scotty went old school by just removing the thermo. Was a common practice back in the day.
Scotty, do you ever get feedback from your customers when you say things like "it's a piece of crap" or "it's not in good shape"? LOL
lol, if it were my ride i'd say " I know but it's MY piece of crap." ;)
My 04 Corolla stater acted up like needed a new one. All it was was the switch on cluch pedal that allows it to start. All mechanic did was clean it with wd40 and adust it a little. No problem after that a cheap fix for sure $20.
'cause Camry's are HOTT!
It looks like it's getting hot in Houston. This reminds me that I should probably replace the thermostat in my vehicles this summer before they give up the ghost on me. They've all been in there for several years now.
I guess I'm the minority who rides his motorcycle to work and back.
But I can testify that besides chains, sprockets, and tires. You'll usually only find new parts for your specific motorcycle at a dealership.
My 98 Camry that had 330K miles on it had a thermostat issue once...it stuck OPEN. Did not notice until winter when it was fine on temp when at idle, but when you started moving the temp would DROP.....not fun.
Radiator cap itself is a likely culprit. Just about lost my mind trying to track a coolant "leak" on my Odyssey and it turned out it was the radiator cap. If the car overheats due to low coolant, test for leaks. If you can't find any, or you hear hissing coming from the cap, it's the cap that needs replacing. And they do go bad after a while.
And be sure to buy proper OEM parts, I made the mistake of buying a cheap cap and thermostat, both of which failed prematurely.
Story time:
I had an F-150. It would only overheat when it was freezing (32F, 0C). It never over heat during the summertime. I replaced the thermostat (nothing), radiator (nothing), hoses (nothing), cabin heater (nothing), coolant (nothing). It would still overheat during the winter. I didn't see any leakage from the water pump and never lost coolant (except during the wintertime when it overheated. On a whim I decided to have the water pump replaced. I found out this Ford designed their impeller on their water pump to be a disk with blades riveted on. The rivets were still there but the blades had worn down to nothing. For some odd reason it would still move coolant enough when it was hot outside but couldn't create enough pressure during the wintertime to push the coolant. Since it would only happen in the wintertime it took me about five years to track the issue down. I'd replace a part and it would seem to work fine, but come next winter I'd have to replace something else.
I like how genuine and honest you are Scotty. Another great video 👍
Always put a rag over the positive terminal on the battery, especially an exposed terminal. A young mechanic I worked with accidentally touched his wrench between the positive and negative posts and the battery went boom. He had to shower for 15 mins before going to the emergency room, but luckily acid burns.
How to wear out an old engine faster or cause the head gasket to fail: take out the thermostat and don't replace it. Having said that, I've had brand new thermostats fail the odd time, so I guess Scotty simply removing it was ruling it out as the problem and will replace it later.
Sometimes they really bury the thermostat and housing and can make it a real fight to get to it. The easiest one I have ever done was on a 1978 Cadillac Coupe De Ville. Right on top and 5 to 10 mins.
My 1985 Plymouth Voyager was right on top. Took about 20 minutes to change. Every other car I've had, the t-stat was a real PITA to get to.
at 1:40 ladies and gentleman is the crux of this channel. SCOTTY NEVER GIVES UP !!
and we love it!
Speaking of starter problems... Let me throw this one out to you - it will take a bit. Bought a 1998 Chevy Monte Carlo in 2002. Later that year it was hit in the front drivers side fender at a 90 degree angle. Car got fixed but AC went out about a year later. I refilled the AC coolant but it leaked out within a week. Said screw it, let it be. Still had the car about 5 years later. I started getting an intermittent burning rubber smell from the engine - couldn't figure it out. Then one day I went to a store and when I came out the car wouldn't start. It sounded like a bad battery, you know that rar, rar, rar sound. Called AAA. Tow truck came, and told me my battery was good. Towed me home. Took the battery out, charged overnight and put back in the car - same thing, won't start sounds like battery. Pulled Alternator. Went to... I think Auto Zone, and had it tested. Worked fine. Won't start.... ??? Starter? Pulled out the starter, had it tested - worked fine. Now what ???? Just for the heck of it I put everything back on and took off the belt - I was guessing at this point. Car started right up! What was it? The AC Motor had seized up! Locked up, wouldn't move. The burning rubber smell was the belt sliding across the AC Motor. Then one day enough rubber built up, like on a racetrack, and everything seized up. Found out you could replace the AC Motor with a pulley. Did that, car ran fine - with no AC of course :(
Cutting out the thermostat will not be nearly as missed in Texas (the southern states) as it would higher north, where you need to it help warm up the car for your heater on cold days.
I changed the coolant in my Camry last summer and used what the manual stated. I found some that was green.
You don't want to drive a car without a thermostat. The engine will never get to regular working temperature, and most importantly, your oil will never go over 100 degrees C, so water will start to build up in the lubricant. Eventually, enough will develop and it will destroy the main bearings.....
Well, a great fix for Texas... Not something you'd want to do in Ontario Canada.
Ontario??? What about Saskatchewan where its -63 with the windchill in january?
That's good to know about the expensive parts for motorcycles. Not knowing that when making a major purchase like that could really bite you in the butt down the road.
You must replace the thermostat in cold weather areas such as Wisconsin. It will never heat up in the winter.
If, after removing your car's thermostat, if your car's computer does not complain and your car runs just fine, well... depending on where you live, you can still have a problem.
When the winter arrives, your car's heat will not warm you up. At best, it might blow lukewarm. On a cold day, you can forget about having a warm cabin.
Also, your gas mileage might suffer a bit.
Always be careful, no matter how much you think you know.
Scotty you should do a video on the Harbor Freight jack stand recall. Maybe you could save some lives by bringing attention to it
My thermostat stuck open in the winter. I would freeze going to work, by the time I get to work heat would just start. This was my first experience with engine trouble as a 16 year old.
Since you spent all that time taking the thermostat off and, if I am the car's owner, I would just spent $30 more and get a new one to put it back on regardless what the problem might be - at least there would be a new thermostat is installed.
That's what I was thinking too.
I agree, but who does what Scotty does? I replace the thermostat even when replacing hoses or anti-freeze.
Maybe it's just me, but I think it's a bit disrespectful not to do at least a basic cleaning of your car before bringing it in for repairs.
I like that plastic bag tip. Thanks Scotty!
Scotty says Toyota Coolant is pink. Of course, when he pops the thermostat housing off, a big gush of green coolant flows out. Hmm,...maybe we figured out the problem?
Thermostat is a on off switch. Switch opens when fluid in motor gets to hot. Hot fluid moves to radiator to cool, cool fluid moves to motor cools it off and thermostat switch closes. Hot fluid in radiator cools off, cool fluid in motor heats up and thermostat switch opens again. If no switch hot fluid does not stop to cool off in radiator, car overheats.
I don’t even like cars that much but when I’m stressed I watch scotty and I just drift off into scotty wonderland where there’s Toyotas and endless money pits! 😁
Thank you Scotty! 5:36 You are truly for the people. We appreciate you. God bless!
Love it when I see Scott doing work
Looks like green Coolant at 3:10 ... Scotty says it needs Pink.
Wrong Coolant can cause component failure
True it was green, but toyotas have pink coolant, it was the wrong coolant.
Love to watch you work!! Cursing is just par for the job🤣🤣👍💖thank you!!
You can only leave the thermostat out in warm temp states.
Why's that?
Basically only do this if you live in the south..... Works wonders in South Texas we get some warm summers down here
@@172-e5s
that's why it's best to just go ahead and put in a new OEM thermostat, so the temperature stays just right, and the car runs right.
Stuck thermostat can be real bad news. Knew a guy that had a Pontiac T34. Really nice car that he bought used. Didn't worry about the temperature. Ruined the engine. Today even in that condition the car would be worth a lot. Back in the early 1980s, not so much. Dime a dozen and was scrapped.
What takes you a few minutes takes the average person an hour or more. Thank you for your great videos!
I had this problem twice in my honda one time it was just low coolant. Another time there was an air bubble in coolant so my sensor was not turning my fans on properly. But these hondas 4 cylinders run so cool that I was driving around without coolant for probably 2 months and my car never overheated until I left it running outside my house parked for an half hr one day.
Pink coolant for a Toyota but looks like green came out. Could using the wrong coolant cause overheating?
I've never thought about using plastic as a wedge when using my sockets. You've probably just saved me 10 years of my life cussing and cursing all while trying to figure out where the dang bolt/nut fell to.
I would not do that thermostat trick anywhere with cold or even cool weather (again). Did this on an old Ford and it wore out pretty quick. That and the 20-50w. Bad during cold starts and you will never have heat in the winter.
Scotty you put pink coolant but green came out... Hope they mix.
Thank you Scotty we will certainly try that tonight!
Instead of completely removing the Thermostat, you can also replace with one that opens up at lower temperature. That way the engine can still warms up in the winter. Good for the engine. That's what I did to my corolla, aha~~~~
actually, the copper barrel of a thermostat is full of wax. the wax expands when it gets hot and squeezes on the conical-shaped pin that runs through the barrel. a thermostat fails when the wax looses its ability to expand. the spring has nothing to do with the failure. the thermostat fell apart in my 1995 ranger and allowed too much flow. it tripped a code 'engine temp too low'. so even back in 95 it tripped the code. i recommend to ALWAYS replace the thermostat. never leave a thermostat out.
9:27 "I don't like playing with other people's toys, only my own"😂😂😂
I thought you were going to say "never set down your 10mm socket"
I'm convinced there is a black hole out there full of them.
This last time they got my 1/4" drive too but probably only because it had a 10mm on it.
Love that plastic bag socket trick!!
I test thermostats by putting it in some boiling water and see if it opens. Use an old pot of course
I work on motorcycles and couldn’t agree more with final comment.
Fair play scotty not a single curse word taking that fiddly thermo housing off..lol
4:22 That is a very genuine moment, lol. I wonder how long it took to find the bolt that fell.
I had my 04 civic overheat on the highway one time and the battery died at the same time...eventually got a new battery and replaced thermostat
Good .
If belt or chain tensioner goes out chain or belt comes off, then it's a long walk back to Cairo.
