Nice Video. Few extra tips/ideas for changing out 95 Integra thermostat: 1. It isn't necessary to remove the air filter housing, only the air flow tube. 2. If the radiator hose is stuck tightly to the thermostat housing you can just remove the thermostat housing and leave the hose attached to it. You can still access the surface of the thermostat housing for cleaning by gently repositioning the radiator hose around a little. This might be a better approach for you if the hose is older and you don't want to risk damaging it during removal. Installation of the new thermostat is still very easy. 3. Some Integra engines have a coolant bleed screw located near the upper radiator attach flange on the engine. 4. The bolts are hard to access but they can be reached with a common 10mm box wrench. If your thermostat is stuck open this will affect idling as the idle sensors never reach operating temperature. After replacing the stuck-open thermostat the engine operating idle dropped from 1.1k to 800 rpm - where it should be. And cold idle rpm dropped into operating range more quickly.
To get big hoses like that off, I use a large L-shaped pick. Slide the tip of the pick under the hose between the hose and the metal pipe, breaking the calcification there, then twist and pull. A very wise mechanic once told me that the first job of a cooling system is to allow the engine to heat up as fast as possible. Although it seems a contrary notion, a closed thermostat at startup is the key.
I had an old 83 Civic. It had a really small aluminium block.I want to say 1,300cc. Anyways,It just wouldn't warm up in the wintertime. I put a new thermostat in & it still wouldn't warm up. lol I eventually blocked off the radiator but every time I hit a little water I lost heat so I made a plate to block off much of the underside too. That finally worked but I had to control the temp by using the heater. lol It was cheap,easy to park at school & got me through the last 6yrs of college
My mom's Ford Explorer was overheating, I found a leaking heater control valve and replaced it but it's still overheating. I can hear the coolant boiling or bubbling which is obviously a very bad sign, what's weird is when the engine is shut off coolant overflows out of the reservoir, then after a while the overflow is sucked back in and the top radiator tube seems to collapse from a vacuum. I'm guessing it's some sort of thermostat problem?
U should have put the heater inside the car on the hottest position possible so the warm coolant can circulate though the heater core too.. There might have been some air bubbles there, and should have put the radiator cap back on after the cooling fans started running and the coolant started circulating. Air in the cooling sys is never good.
Thank you! I have big plans, but it all requires a lot of time and a growing audience. As this channel grows, I am to have the content grow as well! Growth is excellent right now, I'm blown away by how supportive most people are.
Twisting it didn't work. Didn't try any silicone spray but honestly I don't think there's an angle I could get it underneath very well. It was basically glued to the housing. Warm water worked pretty well for me.
thats the one i bought. a 185 that will fail open. someone took my thermostat out of my engine and it ran like crap. i have a mopar 383 engine in my 73 charger.
Didn't think I needed to? Probably a poor answer. When I added fluid it seemed about equivalent to how much came out. I then checked my coolant over the next few days, and added if there was any air at the top of the radiator. Since then it's been full. Do I need to do anything else?
I was actually wondering if this was possible. When I added back fluid though it was nearly equal to how much I lost, which I was surprised to find out. This morning (replaced it yesterday) I added a bit more fluid. Not much but some. It seems to be about right.
I suppose it could use a little cleaning. I'm not too worried about it to be honest. Glad you enjoyed the video! If something comes up that I need to do on my car, I will try to film it.
Damn wish I would have seen this before breaking the thermostat casing. Adding that hot water is prolly the trick. Had to replace the hose, and from trying to take it off the casing broke. ugh shoulda used ducked tape LOL
That engine looks like it can use a cleaning. Spray it with some engine cleaner like Meguiar's then it will sparkle! Nice demonstration as well. I would like to see more of these types of vids from you, you are very informative.
You should really try to get coolant from Honda. The green coolant they sell at AutoZone is not specially made for Honda's aluminum engines. The coolant your using after major use starts creating little holes in the aluminum heads, kind of like pores, if you would.
Thanks for sharing all of this, great information. As far as changing my oil, cost is actually the reason I don't change it myself. It costs me $30 for an oil change, vacuum, and car wash, or I could buy the stuff myself for $25. For $5, I don't have to do it myself, or bring the oil to a shop, my car gets vacuumed, and washed. To me it's the best $5 I could ever spend. Of course, they're getting the oil for much cheaper since they're buying in vastly larger quantities.
Brilliant thank you, maybe you could start a series on how to's with your Honda? Seeing as how most Honda's are the same it would appeal to a broad audience!
So on Hondas coolent from radiator travals from radiator to engine from the upper radiator hose then hot coolent returning from engine comes back to radiator from lower hose? Do all other car makers have a reversed cooling system setup like when thermostat is on upper hose instead?
Thought about? Of course haha. But I burn quite a bit of oil and for now I just want my car to continue working. Likely bad piston rings, and so I wouldn't want to do a turbo without a rebuild. It will be some time before I do any serious modifications. As of now it's 100% stock.
Haha if anything brakes, I suppose I'll make a video. I hope it doesn't come to that though! I do have big plans for the future; we'll see where things go.
Nice video man, i have a 1992 honda integra but recently the coolant bottle is cracked and it leaks and i am trying to find a new one so ya if you can find one i will be very thankful Thanks
shity place for the thermostat, but you did it very good :) My Thermostat is on the top of the engie, it's very easy to change it if it's necessary, the problem is in the bolts wich are often stuck.
Also, I bought the most expensive one they had at the store. Apparently the two cheaper options fail closed, and the one I purchased is supposed to fail open. I'm sure anything is possible though.
I used to have a leaky radiator so I just put in cheap coolant since I went through it so fast. I've since had the radiator replaced, but kept the coolant. I'm skeptical of their being a real difference in the chemical composition of the two fluids. Perhaps I'm being naive.
Ahh okay. I did have the heater all the way to the right. Also, the amount of coolant I added (based on guessing) looks to be about the same as how much drained out. I do believe all of the air is gone, but I should probably try idling and wait for the fans to see if anything else comes out. Will it not overflow once it's heated with the pump running?
Thanks for the gasket tip! That wouldn’t be pretty lol where is the COOLANT TEMPERATURE SENSOR located? The sensor connected to this housing is for the Fan.
If it wasn't for this video I wouldn't have checked the bottom hose witch leads to the thermostat! I only check the top hose lead and thought it didn't have one! Thank you so much on this video! If you still do integras am all eyes and hears brother! You saved my car and saved me time and money! 😎 kudos to you sir!
I too was wondering if you you any plans to add some modifications :) But your channel is absolutely great! You've taught me alot and for that, I thank you! :)
Hi I replaced my thermostat on my integra. However the needel didn't really move so much. I thought it would at least bring it close to mid point what else could cause this.
Thank you so much! Awesome how much you’ve grown over the years. I was overjoyed when I realized this was your channel because I knew I was actually going to get the info I needed here
This isn't a fluke. People are drawn to good content, and you definitely have that. I liked your thermostat vid, even if it was relatively simple. I'm looking forward to more hands-on vids :) Everything else has been very informative. Good luck! Sub'd.
Nicely done. On my 86 Integra, I didn't have to remove the radiator hose; just swung it and the cap out of the way. Getting at that lower left bolt was tough. Used a long arm closed end box wrench to loosen it, then a small open end wrench to remove it. I had to replace a thermostat which a repair shop put in (when they replaced the water pump) which was letting my engine get too hot. Fortunately I had the "old" part, which I had installed just a year earlier. The thermostat they had installed had a gnarly looking gasket too, so I'm wondering what did they really do.
Also, you should do more work on you Integra. I love how you explain everything and I understand it in the graphical visual learning sense, but if you were to relate it by doing work on your integra then you would not only have the techical explaining part, but also the application...and that my friend would be awesome. My bad if im confusing...haha
I agree. I plan to do more work on my Integra. For the time being, I'm just trying to keep it running. Once I get another car, this is going to become my toy.
awesome video man not overly complicated explanations was going to have a shop do it but now after watching your video I'm doing it myself keep up with the integra videos I'm sure a lot of people like me would appreciate some more walk through videos on basic b series engine repair and maintenance
hmm well when switched out my thermostat, and added coolant the thermostat got stuck closed and caused my car to overheat because i didnt bleed the system.
nice vid thanks...i didnt see a bleeder valve 1 or 2 inches away from your therm housing...did you double check?-- i have a 99 cl and am getting ready to change my therm out...i went with honda nippon made in japan and bought two replacement bolts at ace since the dealer(stealer) didnt have them...lol..again thanks!!
Your video is awesome! Concise and informative! The hot water trick on the hose is a great tip. I've worked on my cars for years but my Integra is very recent so just getting oriented. That area is hard to access so seeing you do it with that good camera angle was an excellent reference. Thanks a bunch.
Great video EngineeringExplained! I have a question about gas mileage. Would having a small hole/leak in the catalytic converter contribute to poor gas mileage? Thank you
Good job and demo. Thanks for sharing 👍
woah what a throwback.
Thermostat is usually connected to the top radiator hose. Almost made a big mistake. Thanks for the video
Thanks for your video bro really useful very good explanation

yo this video is ancient history thats crazy

Ever thought about turboing your car? .. These low compression, non-vtec Honda engines take moderate boost very well :)
Sorry my mistake, I live in england. We use Celsius instead of Fahrenheit. The majority of cars over here are 90 degree thermostats.
My mom's Ford Explorer was overheating, I found a leaking heater control valve and replaced it but it's still overheating.

Re fill and bleed coolant system
Thank you! I have big plans, but it all requires a lot of time and a growing audience. As this channel grows, I am to have the content grow as well! Growth is excellent right now, I'm blown away by how supportive most people are.
well look at you bud you made it. good job dude
have you explained cooling and lubrication could you make a video and also a video on service and inspection pls
Twisting it didn't work. Didn't try any silicone spray but honestly I don't think there's an angle I could get it underneath very well. It was basically glued to the housing. Warm water worked pretty well for me.
Better open then closed, I did the same.
thats the one i bought. a 185 that will fail open. someone took my thermostat out of my engine and it ran like crap. i have a mopar 383 engine in my 73 charger.
The top part of the neck of my radiator cap has melted preventing the cap from making a good seal. What is the best solution to fix that?
Didn't think I needed to? Probably a poor answer. When I added fluid it seemed about equivalent to how much came out. I then checked my coolant over the next few days, and added if there was any air at the top of the radiator. Since then it's been full. Do I need to do anything else?
when the engine is cold the engine wears more. the oil needs to reach its working temperature. you can drive it but it's very bad in the long run
I was actually wondering if this was possible. When I added back fluid though it was nearly equal to how much I lost, which I was surprised to find out. This morning (replaced it yesterday) I added a bit more fluid. Not much but some. It seems to be about right.
are you a bit of a tuner? you should add a few aftermarket mods to your Integra ;)
I suppose it could use a little cleaning. I'm not too worried about it to be honest. Glad you enjoyed the video! If something comes up that I need to do on my car, I will try to film it.

Which tool you used to open the 2 bolts?
very helpful video
Brilliant thank you, maybe you could start a series on how to's with your Honda? Seeing as how most Honda's are the same it would appeal to a broad audience!
Creates a seal.
So on Hondas coolent from radiator travals from radiator to engine from the upper radiator hose then hot coolent returning from engine comes back to radiator from lower hose? Do all other car makers have a reversed cooling system setup like when thermostat is on upper hose instead?
you could have tried sealing the end of the radiator hose off and made it air tight so that more fluid didn't come out as you opened the lower point
This is true, peace of mind is a good reason to simply do it yourself.
Thought about? Of course haha. But I burn quite a bit of oil and for now I just want my car to continue working. Likely bad piston rings, and so I wouldn't want to do a turbo without a rebuild. It will be some time before I do any serious modifications. As of now it's 100% stock.
Fahrenheit. If it were Celsius, it would be about 90.5.
I tried twisting, wasn't man enough. Had to use hot water.
Haha if anything brakes, I suppose I'll make a video. I hope it doesn't come to that though! I do have big plans for the future; we'll see where things go.
Nice video man, i have a 1992 honda integra but recently the coolant bottle is cracked and it leaks and i am trying to find a new one so ya if you can find one i will be very thankful
Thanks
Gets a gates racing low temp one it's like 15 bucks and well worth it
Great video by the way
I used a prediluted anti-freeze mix.
shity place for the thermostat, but you did it very good :) My Thermostat is on the top of the engie, it's very easy to change it if it's necessary, the problem is in the bolts wich are often stuck.

That bolt on the left is ruining my life! ratcheting wrenches are a must. Excellent video as always
Me neither, good to hear!
I used to have a leaky radiator so I just put in cheap coolant since I went through it so fast. I've since had the radiator replaced, but kept the coolant. I'm skeptical of their being a real difference in the chemical composition of the two fluids. Perhaps I'm being naive.
VERY informative and VERY well presented. Thank you for taking the time and explaining everything so thorough.
You're very welcome, thanks for watching!
@@EngineeringExplained hej

If it wasn't for this video I wouldn't have checked the bottom hose witch leads to the thermostat! I only check the top hose lead and thought it didn't have one! Thank you so much on this video! If you still do integras am all eyes and hears brother! You saved my car and saved me time and money! 😎 kudos to you sir!
Thank you! I have to change my thermostat today and your video is the best
Very welcome, glad you found the video helpful!
Wanted to say thank you for this video. I was able to change the thermostat on my 1996 Acura Integra from watching this thanks again.
Very welcome, glad you were able to do so on your own, saves a good amount of money, and your engine will run better!
Great car repair video, wish you did a series of these
The coolant from Honda is orange.
great video about to change mine now....
They seem to run fairly cool, at least mine does. It doesn't quite make it to the mid-point for me.
Great video
I too was wondering if you you any plans to add some modifications :) But your channel is absolutely great! You've taught me alot and for that, I thank you! :)
Hi I replaced my thermostat on my integra. However the needel didn't really move so much. I thought it would at least bring it close to mid point what else could cause this.
Perhaps eventually. I just want it to last as long as possible for right now.
Thanks, I'm learning!
Thank you so much! Awesome how much you’ve grown over the years. I was overjoyed when I realized this was your channel because I knew I was actually going to get the info I needed here
Who’s this “kid” 😂🎉
great video!! keep up the hands on demonstrations!

Eventually, yes.
U only have to take the tubing off not the box and pull the lower hose off the housing...1/4 ratchet with a ten and ur done
I think it would be a good idea to purge it after installing the thermostat.
how were you able to remove the bottom housing thermostat nut???
I agree. I plan to do more work on my Integra. For the time being, I'm just trying to keep it running. Once I get another car, this is going to become my toy.
Nice walkthrough. Just did mine on my dc2 type r. I didn't remove the intake though. Thanks for the upload!
Excellent video!
Thanks, good luck!
Use JB weld on the the crack and let it sit for 24 hours! I have a similiar crack and it works perfectly.
My trucks thermostat is 190f, so 195 isn't unbelievable
Thank you! I've never changed a thermostat before. After watching your 8 minute video, I got it done! Woo!
I just did that but my car still getting over heating? You think i should change the radiator?
I would make sure the fans are working first
i love your channel more and more haha I can't wait to see where you go with this.
awesome video man not overly complicated explanations was going to have a shop do it but now after watching your video I'm doing it myself keep up with the integra videos I'm sure a lot of people like me would appreciate some more walk through videos on basic b series engine repair and maintenance

By far one of the BEST vidies on UA-cam.. Thanks !!!
Just for you!
Damn bro this video was a big help thanks keep doing more integra videos
Very welcome!
good stuff, man. very informational
Thanks a lot! I have a 1991 Integra and the procedure was the same just about.
it works fine now .. so idk
Congratulations!
Sounds like you had a bad replacement thermostat.
what pushes the spring on the thermostat? like how does it open and close using heat ?
nice vid thanks...i didnt see a bleeder valve 1 or 2 inches away from your therm housing...did you double check?-- i have a 99 cl and am getting ready to change my therm out...i went with honda nippon made in japan and bought two replacement bolts at ace since the dealer(stealer) didnt have them...lol..again thanks!!
What size are those bolts??? I'm bouta do this , great video btw

That area is hard to access so seeing you do it with that good camera angle was an excellent reference. Thanks a bunch.
would this apply to my 2003 rsx as well?
Not well kinda there in a different spot if it's a k20
Great video EngineeringExplained! I have a question about gas mileage. Would having a small hole/leak in the catalytic converter contribute to poor gas mileage? Thank you
Thanks man that was helpful .. Now i have to change the spark plug wire..!!
Other question how can u change the transition oil?? For the acura 94
