Just made this repair thanks to this video. GET THE FANCY HOSE CLAMP PLIERS!!! On my 2014 Sonic the clamps were deliberately placed so that you can't get to them with normal pliers. Luckily I was able to pick up a pair at Autozone the same day. I did manage to get the small quick release hose off without breaking it, hopefully I can still return the one I bought. HATE THIS CAR! At less than 90,000 miles, I've had to replace air intake hose, EVAP Canister Purge Solenoid, the thermostat, and a few months back the A/C clutch stopped activating. Looking forward to fixing that problem before summer gets here!
Excellent video - my inlet hose did survive, just be careful and observe how it attaches. ! was able to reuse. However i purchased 3 different O-rings for the coolant inlet pipe. Dealer said it was redesigned so original O-ring was not available. New one had increased depth on only fits the new redesigned pipe. I risked it and when I took it off, my O-ring survived for good reattachment. Also you need to e-brake the car and shift the gear first to reach the one bolt. If you unhook the electrical, the car wont shift to N or D lol. Codes are gone - engine light is off! P0304 code to go, Who knows. Being told carbon build up.
Armando Sanchez I don’t think there is an easy way to add a new dedicated temperature gauge but there are other options. The easiest option would be to get a obd2 scanner that has a screen like the launch creader3001 or use you phone with a Bluetooth obd2 scanner.
@@ThePracticalMechanic i have a obdpro in my phone and i use a Bluetooth but i was wondering if i can add a gauge like whent u get a turbo boost gauge .thanks for the info
@@sancheztorres35 There are a few options for that. You can install one of these aluminum fittings in a heater hose or upper radiator hose. With that installed you could put a standard water temp gauge in the car. You will have to verify that the size is correct for the upper radiator hose. amzn.to/2J5gSmB Note: Temp gauge may still be inaccurate if the coolant level gets too low. I found some images while doing a google search that show a gauge pod mounted on the dash above the radio on a Sonic. Not sure if the other models are similar or not.
Great suggestion / advice on the remote hose clamp pliers 👍🏼. And though I bought the coolant hose/pipe in expectation of breaking it, I was able to remove it without breaking - Was able to twist it a tad (breaking it free?) while pulling.
Hello, Excellent video. I just finished changing mine. I noticed a tiny leak coming from somewhere underneath the housing. I am not sure if the bolts need more tightening or if I did something wrong. Help would be appreciated.
What is the part called that the thermostat goes into? The back part, that attaches to side of engine with two hoses coming out the back? We replaced the thermostat itself & when doing that the back part cracked where bolt the thermostat to the (coolant bypass?) Idk what it's called.
Joe Gerhard USA the thermostat housing. I typically buy the complete assemble because cracking is common on the original one. They have aluminum or plastic replacements but either one will work.
@@ThePracticalMechanic yes we bought just the thermostat and it cracked the housing. Luckily we now have the whole assembly and are replacing it now. We're having a little trouble getting the original housing off though. We removed the thermostat part & are now just trying to remove the housing
Does the cooling need to be burped? I have a bleeder screw top of radiator ? should it be opened up while refilling with coolant to let air out also until just coolant starts leaking?
I followed this very closely. I was nervous about the oil cooler pipe so I took my time. However it is leaking right away when I add coolant and it is coming from that attached area although I know the pipe didn't come out when I reattached to thermostat. So now I took the pipe out and the outside O ring does look a little rough. But it wasn't leaking from there before. Should I try a new oring and see ? Leaking a lot . Thank you
I've never owned a car I've hated so much. This car is a true p.o.s. It makes my first car a 1982 ford escort seem like a dream car. Ill never buy another chevy!!!
What kind of issues have you encountered? They are quick cars to zip around town and get good fuel mileage but I agree with you, they aren’t well built. I really hope the automobile market doesn’t get so bad that all cars are disposable instead of repairable.
I agree with you 100 percent. Ive fixed the air intake hose\inlet twice, and it is a huge pain. The reason I am here?I have replaced the thermostat 3TIMES, pretty much after every winter. It is definitely not an easy car to work on, especially the stupid , stupid steel pipe underneath the thermostat housing. So hard, have to do it by feel since the heat shield is hiding the inlet. Stupid design.
Yes...on my THIRD thermostat and was hoping I could do it myself like the old days. I'm gonna watch this a hundred times to convince myself I can do it instead of back to the shop. Hate this friggen car!! Good gas mileage from previous comment. NOPE!!! All it takes is one winter in Illinois and the air intake hose cracks, and the EVAP valve goes. I'm constantly at the shop having work done on this POS.
Joe Gerhard USA chemicals in the coolant slowly eat away at the inferior plastics and as soon as you touch it is falls apart. Heat cycles don’t help it either
Hey so I took that metal part off you said in your video thinking it went with it and I put it back on but I think it’s missing a o ring because it’s leaking out of it do you know if that could be the problem ? Thanks
john jordan The primary reason to replace the entire housing and not just the thermostat is because of leaks. I’m not entirely sure why this is still an issue but GM got a class action against them with the intake gasket failures in the late 90’s-2000’s and VE had issues as well. The plastic engine parts they used were developed by Tyco and they didn’t design it to work with the new dexcool antifreeze so the antifreeze began to eat away the plastic housings and gaskets. Bottom line is the housing are cheaply made and begins to leak rapidly and might fall apart if you replace just the thermostat. I know that wasn’t quite the question you asked but I hope this answers it either way. Thanks for stopping by and let me know if misunderstood the question.
@@ThePracticalMechanic you're right a few days ago I was just changing the thermostat and when I went to install the new one the plastic housing cracked open. so now Im waiting for a new thermostat/housing to arrive tomorrow to finish the change. Also do you know what part number the oring is that goes to the pipe under the thermostat?
I believe it is the pipe that goes to the oil cooler and if it is then this should what you need. here is the link to the oring amzn.to/2OH2MHH. It seems as if GM only sells this item in a pack but if you go to the dealer they may sell you just one. Here is the part number I found 55556547. Hope this helps and Good Luck
when you say radiator cap you mean the antifreeze little jug you poured it in right ? because i don't see a actually radiator cap ? just making sure i did this right
awesome i did this with my Father it took us 6 hours because we didn't have tools for those silly little things on the hose.. lol and of course that one piece broke so we ordered the last one on amazon that took about 1 hour to put on for us but we saved 350$ doing it !
hey it's me again ... so my GF says she hears a "thump " sound sometimes when she turns the car on ... but when i go to turn it on i havent hear it yet ... so she says it sometimes happens and sometimes doesnt ? should i be worried? the sound happens when turning the car on as soon as its on it stops so only during the "on" action.
Excellent video. I am getting ready to do this on a 2012 1.8 Chevy Cruze. Question, will it help if I drain about a gallon of coolant so as to prevent excessive coolant run out from the ports and hoses. Thanks again. Semper Fi, USMC.
I have a tiny tiny leakage still..About the size of a quarter ..not much but still..I think it is dripping down off of the catalytic converter. Other than that your video almost worked perfectly for me. Any thoughts on why that tiny leak is happening? And only after the car has been driven and warmed up..
I have 2013 sonic with a bad thermostat, is it necessary to replace the whole housing or can I replace the thermostat and its housing instead (the aluminum section)?
Thanks for the video! I replaced my thermostat last night. The check engine light hasn't come back on but there is still no a/c. Any ideas as to why this is?
You may have more than one issue. I would make sure the codes were cleared out and check again. You may have a low refrigerant charge or an electrical issue preventing the a/c operation.
Question! First off, love your videos. I have a 2014 Chevy Cruze LS 1.8 and you videos are extremely informative and helpful. I just replaced my thermostat and thermostat housing (all metal Dorman product) and I also replaced my throttle body heater inlet pipe (as it broke when I replaced the thermostat and housing). When I start my car and drive, the engine temperature gauge doesn't register and my radiator fan is often running on high. It appears I am still leaking coolant out of the bottom passenger side of my radiator. The coolant leak is not extreme, I can drive a few hours before my coolant gets too low. I am concerned about this and my temperature gauge not registering. Any suggestions?
Thank Y Y. I will call the dealership for the next one and see if they will take care of it for the customer. They are right across the street from my shop so I have easy access.
Omg Yes!!!! I was S***** Bricks since my car is leaking. Now I just need the money for the new one 😭😭😭. Now I know how to replace everything and do it. Ima save this video
most of these don't have a heater control valve that controls the flow of coolant thru the heater core. the heat output is instead controlled with a door inside the heater box. If you have no heat you either have poor coolant flow, low coolant, low coolant temp or a heater box/actuator/control head issue.
The broken section was in the thermostat housing but since I installed a new thermostat housing I didn’t worry about it. You might try threading a screw or bolt into the remaining piece and try to pull it out.
When rhat hose connectir broke, i fit a 90 degree brass reducer fitting, rubber hose and clamps and connected it to the housing and that rigid plast line 😊😊😊😊
Great video and explanation - thank you. I bought my 2012 new and planned on it being a "throw away car". I drove the heck out of it for two years and gave it to my son. He still has it and it's got 140K miles on it. I'm about to make this thermostat replacement repair. What size inverted torx socket is that?
We just had our car looked at, heater has been barely working. Need to get the car up to about 80mph for any heat. We were told this part was $100 so I just wanted to make sure it's what we need.
It could be the cause since it is a common issue. Low coolant or a plugged heater core could also cause the problem. Has the check engine light turned on? Normally the engine light will illuminate before you have a noticeable lack of heat but it could have failed rapidly. Was that the total estimate? The estimate should include thermostat, oring, coolant and may include gasket and coolant hose from thermostat to throttle body and then it should also include labor. If your planning on doing the repair yourself then there are some links in the description for the parts. The thermostat is about $40-50 aftermarket and a dealership thermostat could be in the $100 range.
@@ThePracticalMechanic the check engine light did come on but it was after we lost heat which did happen quickly. My boyfriend was the one that went and had the car looked at by VIP auto. I am not sure if they gave him an estimate but they told him to call chevy to order the part. I'd love to be able to do this ourselves but neither of us is really mechanically capable of such things.
It’s kinda strange that the shop wants you to get your own parts. At our shop we rarely allow customer supplier parts just for the warranty and liability. You might want to price the job from a local dealer and see if it is close. Also a local napa auto care center will have a nationwide peace of mind warranty even if you have them install the factory thermostat.
@@ThePracticalMechanic I purchased the thermostat you had supplied the link to above. VIP put the part in for us. I mentioned the missing oring (from reviews saying they had coolant leaks). After we got the car back we had heat again for one day and then the check engine light came back on. It was also leaking coolant. I wasn't sure where to look to see if was missing an o ring. Is it possible we got a faulty part?
The o ring will be hard to see and it is used between two mounting surfaces. If it is still leaking then the part might be damaged or the leak is coming from somewhere else. Do they offer a warranty on their work? You might have them check it again to see what’s leaking.
Not sure if it has an actual name but the hose from the thermostat housing to the throttle body is the closest name I can give it. I have a link to it in the description also. It should be the second on in the list.
@@ThePracticalMechanic thanks man, your video really helped me out. And ya that's how I found it with that same way you worded it. Fortunately, it was just the o ring that I had to replace.
I believe it is the pipe that goes to the oil cooler and if it is then this should what you need. here is the link to the oring amzn.to/2OH2MHH. It seems as if GM only sells this item in a pack but if you go to the dealer they may sell you just one. Here is the part number I found 55556547. Hope this helps and Good Luck.
Jason Williams I don’t remember the exact size it might have been an e10 inverted torx. Here is a cheap set on the net or you can get some from your local parts store for cheap as well www.amazon.com/dp/B079ZP2FM1/ref=cm_sw_r_cp_tai_vVU.Bb5736GGD
I can’t remove the hose to the throttle body. I have moved the clamp all the way and still unable to remove the hose. I should just able to pull it. Right? Feels like it glued!!!!
Super Time sometimes the rubber adheres itself to the pipe on the throttle body. Using some pliers to twist the hose will normally break it loose but if you are replacing it you can cut the hose off the pipe as well. It also makes it easier if you remove the intake hose first if you haven’t already.
ThePracticalMechanic Thanks, I cut the hose off and able to install the new one. Also noticed the air intake tube cracked and need to replace it. Thanks again!!
No problem glad to help. At least you noticed the intake hose now. They can cause surging, low power and a check engine light for lean running if the crack gets big enough.
Same here. Changed mine yesterday. Had like ,8 ohms on the old heater and the new one has 14.8 ohms resistance and was feeling good about it but my scanner says I have a perminant p0599 fault.. I don.t have a mill light on the dash yet but know I will let you know if I get it fixed
I have a 2014 Sonic lt with a 1.4 turbo I changed my thermostat housing because it was cracked I added more coolant but it still makes a bubbling sound any clue on what it might be?
Gilbert Estrella is bubbling sound like boiling water or does it just sound like rushing water? Does it overheat? There could be air trapped in the cooling system and several short trips should work out the air. The coolant cap could be defective and not holding pressure on the cooling system which will allow the coolant to boil at a lower operating temperature. I believe they had issues with the coolant reservoir leaking on the 1.4l models. Water pumps fail often and either leak or quit pumping coolant. Hopefully it hasn’t been overheated because it has then the head gaskets may have been damaged.
@@ThePracticalMechanic no it hasn't been over heating just had a lil crack on the housing at first I put jb welt on it . worked out for a lil but started leaking again so I decided replace it but I don't remember if I took the air out of it let me go out in give it a shot.
@@ThePracticalMechanic also I forgot to tell you I did have a crack in my coolant reservoir I replaced that as well I took it for a drive last night in when I got home I noticed there was more coolant then I had put it in.
Did the new coolant reservoir come with a new cap? If the coolant level raised up in the overflow bottle then either air is trapped in the system and pressurized causing the coolant level to raise in the bottle or the cap isn’t holding enough pressure. Several warm ups and cool downs to purge the air and if that doesn’t work you may have to pull a vacuum on the cooling system to get the air out. Another thing you can try is parking it on an incline. If the head gasket has failed it will push exhaust into the cooling system and raise the level as well so hopefully it’s not that.
Joe Gerhard USA The coolant slowly eats away at the inferior plastic. That combined with multiple heat cycles of every day driving makes it fall apart as soon as you touch it.
@@ThePracticalMechanic understood. Luckily we got it off without issue. Its only got 84000 miles. Did you have any trouble removing the housing, the part that bolts to the engine, that has the two hoses coming from the rear?
So the code Po599 is the thermostat needs replacing and if so what can course that and what I mean is I've replaced it and then the water pump and then the top line that goes from the coolent tank to the motor and now this is happing
Yes it seem to haven’t not been able to test it out yet waiting on the hose that goes on top the Throttle Body Heater pipe. It broke on me also poor design by Chevy
With parts,labor and fluids $200-300 is probably the norm. I think you can look up typical repair prices on repairpal but the Estimates don’t always include fluids or other items needed.
L Edward It was the coolant hose that goes from the thermostat housing to the throttle body that broke. It broke of inside the thermostat housing but I wasn’t too worried about it since I was replacing the housing anyways. I just had to replace the hose at the same time.
Hey man just did this on my gfs Chevy.. hate modern cars.. now her car won’t rev past 3000rpm. Just stops it right there. What did I do wrong?? She has work tomorrow and this is being a pain in my ass
good morning, maybe you don't know but the coolant is very polluting it doesn't seem like a good thing to drop it to the ground. also because it should be disposed of in collection centers
As it so happens I use a container under the vehicle to catch the coolant that spills and pay a coolant and oil recycling company to pick it up. I also pay hazardous material taxes and insurance to cover my facility in the rare chance of accidental spills. These cars do much more harm to the environment than I do. They constantly burn oil and leak coolant. Actually almost all Chevrolets have been having issues with oil burning and coolant leaks since the early 2000’s. Just sharing since you brought up the environment. Computers and cellphone are also very polluting to the environment. All that processing and strip mining to gain the lithium that make up the battery in all modern electronics. Thank you for your concern but I try to take care of the environment to the best of my abilities.
Thanks for the video. Spent 2 hours to take the old one out and haven’t installed new one yet. I had to take thermostat out first because I couldn’t reach the right bolt in the bottom. How do you know if the O ring need to be replaced? I need to check it first tomorrow before install the new thermostat housing tomorrow. Thanks!!!
Super Time If the O ring has flat spots all the way around where slides into the housing Then it may not seal properly. Also check the seal for any cracks or nicks that would cause a leak. Also if you reinstall it into the housing it should fit snugly and require a little bit a effort or wiggling to install that small pipe into the bottom of the housing. The local parts store may have an O-ring that will match based off of dimensions alone but if you try to remove that one you risk cracking it so the part store doesn’t have one then you might be SOL until you can get one at the dealership. I wish they would include that O-ring with a new thermostat housing.
Thanks. The part did state it has O ring. “➤ Function: Comes a complete repair kit with thermostat housing - Include thermostat housing with sensor, thermostat, temp sensor, gasket and O-ring. Helping you repair leaking thermostat housings and correct engine” is this the same O ring?
Mine is just stuck open... why not just replace the thermostat only if the rest isn't leaking? If there is a good reason I'll buy the whole thing but it doesn't look like I should need to.
The plastic is normally brittle and ready to break. Some are successful at replacing the thermostat but they will normally start leaking in less than a year if not instantly. As a technician the car coming back isn’t worth the savings to attempt a thermostat only.
That sounds normal to me. Many GM vehicle have the low speed fan come on at 220 and high speed at 235-240. Its best to watch coolant temp and fan command with a scan tool to determine if the fan is turning on at the correct temp.
@@ThePracticalMechanic mr one more thing the knock sensor where is located and is easy to remove it ?i got a code p0325 so i want to replace it but i saw other videos from diferen models and some of them u have to remove plany parts .thanks in advance
Well you could replace it now before it fails or wait until it starts leaking and then replace it. There really isn’t a set time point for replacement, most replace it after the check engine light comes on with a P0128 thermostat code or when they get a coolant leak.
L Edward I don’t remember the exact size it might have been an e10 inverted torx. Here is a cheap set on the net or you can get some from your local parts store for cheap as well www.amazon.com/dp/B079ZP2FM1/ref=cm_sw_r_cp_tai_vVU.Bb5736GGD
Yes you should attach the wires back to the same locations they were removed from. The sensors are checking different things and the computer might get confused if they are swapped.
Stevenson Ceus It’s not a super hard task as long as you take your time you should be able to do it. Although it seems like a quick and easy process in the video it may take you much longer to perform the replacement. I think the worst part might be removing all the clamps and unbolting the lower metal pipe from the housing. You may want to watch the video a few times and make sure you have the correct tools and feel comfortable with the job.
heater in mine wasnt very good, so i changed the thermostat/housing its good now, on the old one the o ring around the thermostat was coming out which lets coolant by, just like if it was the thermostat not closing all the way. if changing just the part i did you only have to remove the radiator hose, then unbolt the oil cooler pipe and loosen/back off the bolts to the plastic housing thats against the head to make room to remove the thermostat. also with that code you only have to change that thermostat housing as the heating element right by the thermostat is the cause.
It's very common for the large air inlet hose to crack and fall apart between the throttle body and the air filter housing. I would check that and also make sure all the sensors are plugged in properly.
That hose from tstat to throttle body is a pain. You make it look so easy ,I'm stuck like 20 min. Either it plugs in one side and not the other,as if it's not long enough. It's right part# str8 from chevy.its just a pain.
I’m not real impressed with the design. It seems like you have to route the hose just right to have enough slack to install it. Did you get it to fit yet?
I put it down. Will try again.. crazy, I've done from brakes to plugs timing belt etc,etc but this little hose seem harder than the timing on this car. 😐😐 lol
Jose Deleon Sometime walking away for a day will fix the issue. I do that from time to time although I can’t walk away for too long unless it’s my own personal vehicle. Good luck tomorrow.
@@ThePracticalMechanic I put it down cause I work over nights and tried after work. Had to run and get part from dealer 30 min away woke up and had to go to daughter's event in school. I'll get it. Thanks
Hello, tkanks for the video that help me a lot, when I get off the air intake hose in the thermostat I broke it, my carr is a Chevy Sonic 2012 1.8 LT and my question is if it the same part Numbers AC Delco 25192905. Appreciate...
Paul Wilson if I get the chance I will record it. I don’t personally have one of the vehicles so I will have to wait until one comes in the shop that needs a coolant flush or I can show the procedure on the next thermostat I do. 👍🏻
@ThePracticalMechanic makes sense as long as you're willing to do the repair for less without replacing the housing. As long as you explain this to your customer they may choose to save money in the sort term. If you suggest the housing replacement to save on future labor and they agree then I don't see an issue with it.
Chevy Sonic. The square radiator fan has a green resistor in it that has two fan speeds. High speed and low speed. You can not buy that resistor separately. The fan tests good, but the high speed resistor goes out and you only have low speed and your engine will still overheat and your A/C will not blow cold. You need to buy a new fan for $65 on ebay and it does go bad every 100,000 miles or so, because the turboed 4 cyl. engine creates so much heat and causes stuff to fail. That bad resistor fan might blow your 40 Anp fuse in your fuse box. Your fuse box in the engine compartment has two 40 Amp fuses. One fuse supplies power to the radiator fan and the other 40 Amp fuse supplies power to your blower motor in the cab of the car. The engine coolant temp sensor can also go bad from all the heat in the engine compartment. The sensor is actually part of your electronically controlled thermostat housing, so the thermostat, thermostat housing and engine coolant sensor come as one piece when you buy them on ebay. So what it comes down to is you should check 4 things if your engine is overheating(high and low speed resistor that comes with the new radiator fan, the thermostat, the coolant temp sensor that is mounted on the thermostat housing, and the 40 Amp fuse for the radiator fan that is in the fuse box in the engine compartment).
Cars should not be this much for trouble to repair. Come on America! You can do better! Start using your brains and stand up to politicians and corporations trying to make your life harder! This is just going to keep getting worse and worse because people just let them get away with it.
🤣🤣 couldn’t agree more. We should force GM CEOs and engineers to drive 5/10/15yr old vehicles they produce and decide what they can do better. These cars rarely make it past the 10 yr mark. All of my Toyotas have 200,000+ and I have three with over 300k. We did valve cover gaskets on a Toyota 4Runner last week with 550,000 miles and was still running strong.
I personally don’t disconnect the battery on any vehicle unless I absolutely have to. Many vehicle require radio codes, XM subscription information, onstar setting, radio settings, power window and sunroof initialization. Many other vehicle have intermittent module failure upon battery reconnection (mainly Dodge vehicle). I just use caution when working near the battery. Many may choose to unhook the battery when performing repairs like this. Thanks for checking out the video. 👍🏻
Also you made no note or comment on inlet vs outlet heater hoses. They’re identical size and length, super easy to get swapped by mistake, like my sloppy mechanic did, causing problems....pretty sloppy:(
Just made this repair thanks to this video. GET THE FANCY HOSE CLAMP PLIERS!!! On my 2014 Sonic the clamps were deliberately placed so that you can't get to them with normal pliers.

Great video, very well explained along with a good camera angle.

What kind of issues have you encountered? They are quick cars to zip around town and get good fuel mileage but I agree with you, they aren’t well built. I really hope the automobile market doesn’t get so bad that all cars are disposable instead of repairable.
I agree with you 100 percent. Ive fixed the air intake hose\inlet twice, and it is a huge pain. The reason I am here?I have replaced the thermostat 3TIMES, pretty much after every winter. It is definitely not an easy car to work on, especially the stupid , stupid steel pipe underneath the thermostat housing. So hard, have to do it by feel since the heat shield is hiding the inlet. Stupid design.
Yes...on my THIRD thermostat and was hoping I could do it myself like the old days. I'm gonna watch this a hundred times to convince myself I can do it instead of back to the shop.
Hate this friggen car!!
Good gas mileage from previous comment. NOPE!!!
All it takes is one winter in Illinois and the air intake hose cracks, and the EVAP valve goes.
I'm constantly at the shop having work done on this POS.
@@ThePracticalMechanic how did that top hose break? What made it break?
Joe Gerhard USA chemicals in the coolant slowly eat away at the inferior plastics and as soon as you touch it is falls apart. Heat cycles don’t help it either
Hey so I took that metal part off you said in your video thinking it went with it and I put it back on but I think it’s missing a o ring because it’s leaking out of it do you know if that could be the problem ? Thanks
How did you drain the cooling system and what is the purpose of the coolant pipe
is the thermostat heater not in the main stat assembly? Therefor negating replacing coolant pump housing and just replace thermostat? Thanks
john jordan The primary reason to replace the entire housing and not just the thermostat is because of leaks. I’m not entirely sure why this is still an issue but GM got a class action against them with the intake gasket failures in the late 90’s-2000’s and VE had issues as well. The plastic engine parts they used were developed by Tyco and they didn’t design it to work with the new dexcool antifreeze so the antifreeze began to eat away the plastic housings and gaskets. Bottom line is the housing are cheaply made and begins to leak rapidly and might fall apart if you replace just the thermostat.
I know that wasn’t quite the question you asked but I hope this answers it either way.
Thanks for stopping by and let me know if misunderstood the question.
@@ThePracticalMechanic you're right a few days ago I was just changing the thermostat and when I went to install the new one the plastic housing cracked open. so now Im waiting for a new thermostat/housing to arrive tomorrow to finish the change. Also do you know what part number the oring is that goes to the pipe under the thermostat?
I believe it is the pipe that goes to the oil cooler and if it is then this should what you need. here is the link to the oring amzn.to/2OH2MHH. It seems as if GM only sells this item in a pack but if you go to the dealer they may sell you just one. Here is the part number I found 55556547. Hope this helps and Good Luck
@@ThePracticalMechanic Cheers ive changed my thermostat twice with no issues, no leaking from plastic housing but maybe im just lucky.
Lol you must have been lucky if you haven’t had any leaks yet.
when you say radiator cap you mean the antifreeze little jug you poured it in right ? because i don't see a actually radiator cap ? just making sure i did this right
Yup. I got so used to calling them radiator caps that I forget to change my terminology when vehicles switch to coolant reservoirs.
awesome i did this with my Father it took us 6 hours because we didn't have tools for those silly little things on the hose.. lol and of course that one piece broke so we ordered the last one on amazon that took about 1 hour to put on for us but we saved 350$ doing it !
Sweet! Nothing like some Father-Son car repairs. Glad you saved some cash also.
Thank you for the video ! couldn't have done it without you !
hey it's me again ... so my GF says she hears a "thump " sound sometimes when she turns the car on ... but when i go to turn it on i havent hear it yet ... so she says it sometimes happens and sometimes doesnt ? should i be worried? the sound happens when turning the car on as soon as its on it stops so only during the "on" action.
Excellent video. I am getting ready to do this on a 2012 1.8 Chevy Cruze. Question, will it help if I drain about a gallon of coolant so as to prevent excessive coolant run out from the ports and hoses. Thanks again. Semper Fi, USMC.
I have a tiny tiny leakage still..About the size of a quarter ..not much but still..I think it is dripping down off of the catalytic converter. Other than that your video almost worked perfectly for me. Any thoughts on why that tiny leak is happening? And only after the car has been driven and warmed up..
I have 2013 sonic with a bad thermostat, is it necessary to replace the whole housing or can I replace the thermostat and its housing instead (the aluminum section)?
Great video!
Thanks for the video! I replaced my thermostat last night. The check engine light hasn't come back on but there is still no a/c. Any ideas as to why this is?
You may have more than one issue. I would make sure the codes were cleared out and check again. You may have a low refrigerant charge or an electrical issue preventing the a/c operation.
Yes that sensor that always breaks is why I never did the whole housing just the stat
What size o ring for oil cooler pipe on the thermostat end
Question!
First off, love your videos. I have a 2014 Chevy Cruze LS 1.8 and you videos are extremely informative and helpful.
I just replaced my thermostat and thermostat housing (all metal Dorman product) and I also replaced my throttle body heater inlet pipe (as it broke when I replaced the thermostat and housing).
When I start my car and drive, the engine temperature gauge doesn't register and my radiator fan is often running on high. It appears I am still leaking coolant out of the bottom passenger side of my radiator.
The coolant leak is not extreme, I can drive a few hours before my coolant gets too low. I am concerned about this and my temperature gauge not registering.
Any suggestions?
There is a RECALL on the air intake hose!
Thank Y Y. I will call the dealership for the next one and see if they will take care of it for the customer. They are right across the street from my shop so I have easy access.
I’m having an issue with the bolts going back into the block. They are not going all the way in.
Once the other part breaks every time like you said , I'll just have the dealer do it :)
where can i purchase remote pliers ?great video very well explained great job
I couldn’t find the purple ones last time I looked but some blue ones are listed in the description. Thanks for watching.
What is the Fahrenheit temperature when the fan must to turn on .and at what temperature the fan must to off?
Omg Yes!!!! I was S***** Bricks since my car is leaking. Now I just need the money for the new one 😭😭😭. Now I know how to replace everything and do it. Ima save this video
2015 sonic . Heater only blows cool air. Where is the heater control valve located?
Good video.
most of these don't have a heater control valve that controls the flow of coolant thru the heater core. the heat output is instead controlled with a door inside the heater box. If you have no heat you either have poor coolant flow, low coolant, low coolant temp or a heater box/actuator/control head issue.
@@ThePracticalMechanic thanks
How did you remove the broken-off portion of the throttle body heater hose?
The broken section was in the thermostat housing but since I installed a new thermostat housing I didn’t worry about it. You might try threading a screw or bolt into the remaining piece and try to pull it out.
When rhat hose connectir broke, i fit a 90 degree brass reducer fitting, rubber hose and clamps and connected it to the housing and that rigid plast line 😊😊😊😊
Where is the link for the special inverted socket?
amzn.to/35JAiaU here is a full set of them on amazon. there are other set on amazon as well but they do not come with a case.
What socket did you use to remove the thermostat ? You said they where special ones ?
They are inverted torx sockets.
5/16 or 8mm works
Great video and explanation - thank you. I bought my 2012 new and planned on it being a "throw away car". I drove the heck out of it for two years and gave it to my son. He still has it and it's got 140K miles on it. I'm about to make this thermostat replacement repair. What size inverted torx socket is that?
For clarification it's an e10 reverse torx
We just had our car looked at, heater has been barely working. Need to get the car up to about 80mph for any heat. We were told this part was $100 so I just wanted to make sure it's what we need.
It could be the cause since it is a common issue. Low coolant or a plugged heater core could also cause the problem. Has the check engine light turned on? Normally the engine light will illuminate before you have a noticeable lack of heat but it could have failed rapidly.
Was that the total estimate? The estimate should include thermostat, oring, coolant and may include gasket and coolant hose from thermostat to throttle body and then it should also include labor.
If your planning on doing the repair yourself then there are some links in the description for the parts. The thermostat is about $40-50 aftermarket and a dealership thermostat could be in the $100 range.
@@ThePracticalMechanic the check engine light did come on but it was after we lost heat which did happen quickly. My boyfriend was the one that went and had the car looked at by VIP auto. I am not sure if they gave him an estimate but they told him to call chevy to order the part. I'd love to be able to do this ourselves but neither of us is really mechanically capable of such things.
It’s kinda strange that the shop wants you to get your own parts. At our shop we rarely allow customer supplier parts just for the warranty and liability. You might want to price the job from a local dealer and see if it is close. Also a local napa auto care center will have a nationwide peace of mind warranty even if you have them install the factory thermostat.
@@ThePracticalMechanic I purchased the thermostat you had supplied the link to above. VIP put the part in for us. I mentioned the missing oring (from reviews saying they had coolant leaks). After we got the car back we had heat again for one day and then the check engine light came back on. It was also leaking coolant. I wasn't sure where to look to see if was missing an o ring. Is it possible we got a faulty part?
The o ring will be hard to see and it is used between two mounting surfaces. If it is still leaking then the part might be damaged or the leak is coming from somewhere else. Do they offer a warranty on their work? You might have them check it again to see what’s leaking.
The hose you broke what's it called? I had the same problem now I need to replace too
Not sure if it has an actual name but the hose from the thermostat housing to the throttle body is the closest name I can give it. I have a link to it in the description also. It should be the second on in the list.
@@ThePracticalMechanic thanks man, your video really helped me out. And ya that's how I found it with that same way you worded it. Fortunately, it was just the o ring that I had to replace.
I need to get the o ring for the pipe under the thermostat. What size/ part number is it?
I believe it is the pipe that goes to the oil cooler and if it is then this should what you need. here is the link to the oring amzn.to/2OH2MHH. It seems as if GM only sells this item in a pack but if you go to the dealer they may sell you just one. Here is the part number I found 55556547. Hope this helps and Good Luck.
I still cant seem to find it. In need of it pretty bad. This stuff is bs. Way too much for something as simple
This simple job looks like a nightmare. It shouldn't be this much work to replace one part
It’s really not all that bad but you are correct, they could have/ should have made it simpler.
What socket do you need to remove the bolts for the Thermostat?
Jason Williams I don’t remember the exact size it might have been an e10 inverted torx. Here is a cheap set on the net or you can get some from your local parts store for cheap as well www.amazon.com/dp/B079ZP2FM1/ref=cm_sw_r_cp_tai_vVU.Bb5736GGD
@@ThePracticalMechanic Thanks a lot!
No problem
I can’t remove the hose to the throttle body. I have moved the clamp all the way and still unable to remove the hose. I should just able to pull it. Right? Feels like it glued!!!!
Super Time sometimes the rubber adheres itself to the pipe on the throttle body. Using some pliers to twist the hose will normally break it loose but if you are replacing it you can cut the hose off the pipe as well. It also makes it easier if you remove the intake hose first if you haven’t already.
ThePracticalMechanic Thanks, I cut the hose off and able to install the new one. Also noticed the air intake tube cracked and need to replace it. Thanks again!!
No problem glad to help. At least you noticed the intake hose now. They can cause surging, low power and a check engine light for lean running if the crack gets big enough.
I did replace it and the code won’t go off at all I deleted it more than 3 times and it go back what is your recommendations for me
Same here. Changed mine yesterday. Had like ,8 ohms on the old heater and the new one has 14.8 ohms resistance and was feeling good about it but my scanner says I have a perminant p0599 fault.. I don.t have a mill light on the dash yet but know I will let you know if I get it fixed
I have a 2014 Sonic lt with a 1.4 turbo I changed my thermostat housing because it was cracked I added more coolant but it still makes a bubbling sound any clue on what it might be?
Gilbert Estrella is bubbling sound like boiling water or does it just sound like rushing water? Does it overheat? There could be air trapped in the cooling system and several short trips should work out the air. The coolant cap could be defective and not holding pressure on the cooling system which will allow the coolant to boil at a lower operating temperature. I believe they had issues with the coolant reservoir leaking on the 1.4l models. Water pumps fail often and either leak or quit pumping coolant. Hopefully it hasn’t been overheated because it has then the head gaskets may have been damaged.
@@ThePracticalMechanic no it hasn't been over heating just had a lil crack on the housing at first I put jb welt on it . worked out for a lil but started leaking again so I decided replace it but I don't remember if I took the air out of it let me go out in give it a shot.
@@ThePracticalMechanic also I forgot to tell you I did have a crack in my coolant reservoir I replaced that as well I took it for a drive last night in when I got home I noticed there was more coolant then I had put it in.
Did the new coolant reservoir come with a new cap? If the coolant level raised up in the overflow bottle then either air is trapped in the system and pressurized causing the coolant level to raise in the bottle or the cap isn’t holding enough pressure. Several warm ups and cool downs to purge the air and if that doesn’t work you may have to pull a vacuum on the cooling system to get the air out. Another thing you can try is parking it on an incline. If the head gasket has failed it will push exhaust into the cooling system and raise the level as well so hopefully it’s not that.
What made that top hose break? How did it break?
Joe Gerhard USA The coolant slowly eats away at the inferior plastic. That combined with multiple heat cycles of every day driving makes it fall apart as soon as you touch it.
@@ThePracticalMechanic understood. Luckily we got it off without issue. Its only got 84000 miles.
Did you have any trouble removing the housing, the part that bolts to the engine, that has the two hoses coming from the rear?
@@ThePracticalMechanic also thank you sir!
This was extremely helpful!
@@ThePracticalMechanic I want to say THANK YOU! Your video was extremely helpful! God bless you sir.
What was that hose that broke?
Link to it in the description. I don’t remember the actual name other than it runs from the thermostat to the throttle body.
So the code Po599 is the thermostat needs replacing and if so what can course that and what I mean is I've replaced it and then the water pump and then the top line that goes from the coolent tank to the motor and now this is happing
The clamp going on the hose to the rear of the housing was crooked might and up leaking. Otherwise super helpful video thumbs up
I love your video by the way. I just replaced my dads thermostat housing. But I went with all metal one bought it at Rockauto. Thank you for the video
south9490 nice!! Did the all metal one fit good?
Yes it seem to haven’t not been able to test it out yet waiting on the hose that goes on top the Throttle Body Heater pipe. It broke on me also poor design by Chevy
I’m not very good with cars so how much do you think this would cost me to get it done in a shop 😕
With parts,labor and fluids $200-300 is probably the norm. I think you can look up typical repair prices on repairpal but the Estimates don’t always include fluids or other items needed.
Hey what's the name of the upper hosing u broke
L Edward It was the coolant hose that goes from the thermostat housing to the throttle body that broke. It broke of inside the thermostat housing but I wasn’t too worried about it since I was replacing the housing anyways. I just had to replace the hose at the same time.
Hey thanks did u made a video on how to take out the housing that goes to the throttle
L Edward I replace the hose around 8:00 in this video.
Thank you so much an thanks u for showing me the parts # great help for me am order it
Are the bolts to the aluminum pipe to exhaust manifold the same size and type of the four bolts that hold the assembly?
Yes it is!
Hey man just did this on my gfs Chevy.. hate modern cars.. now her car won’t rev past 3000rpm. Just stops it right there. What did I do wrong?? She has work tomorrow and this is being a pain in my ass
good morning,
maybe you don't know but the coolant is very polluting it doesn't seem like a good thing to drop it to the ground. also because it should be disposed of in collection centers
As it so happens I use a container under the vehicle to catch the coolant that spills and pay a coolant and oil recycling company to pick it up. I also pay hazardous material taxes and insurance to cover my facility in the rare chance of accidental spills. These cars do much more harm to the environment than I do. They constantly burn oil and leak coolant. Actually almost all Chevrolets have been having issues with oil burning and coolant leaks since the early 2000’s. Just sharing since you brought up the environment. Computers and cellphone are also very polluting to the environment. All that processing and strip mining to gain the lithium that make up the battery in all modern electronics. Thank you for your concern but I try to take care of the environment to the best of my abilities.
Thanks for the video. Spent 2 hours to take the old one out and haven’t installed new one yet. I had to take thermostat out first because I couldn’t reach the right bolt in the bottom. How do you know if the O ring need to be replaced? I need to check it first tomorrow before install the new thermostat housing tomorrow. Thanks!!!
Super Time If the O ring has flat spots all the way around where slides into the housing Then it may not seal properly. Also check the seal for any cracks or nicks that would cause a leak. Also if you reinstall it into the housing it should fit snugly and require a little bit a effort or wiggling to install that small pipe into the bottom of the housing. The local parts store may have an O-ring that will match based off of dimensions alone but if you try to remove that one you risk cracking it so the part store doesn’t have one then you might be SOL until you can get one at the dealership. I wish they would include that O-ring with a new thermostat housing.
Thanks. The part did state it has O ring. “➤ Function: Comes a complete repair kit with thermostat housing - Include thermostat housing with sensor, thermostat, temp sensor, gasket and O-ring. Helping you repair leaking thermostat housings and correct engine” is this the same O ring?
They could be referring to the O-ring that seals the housing to the cylinder head But they may also include the O-ring for the pipe.
ThePracticalMechanic I will verify it tomorrow. Thanks!!!!
Mine is just stuck open... why not just replace the thermostat only if the rest isn't leaking? If there is a good reason I'll buy the whole thing but it doesn't look like I should need to.
The plastic is normally brittle and ready to break. Some are successful at replacing the thermostat but they will normally start leaking in less than a year if not instantly. As a technician the car coming back isn’t worth the savings to attempt a thermostat only.
That “pipe” just fell off and not I have no clue how to get it back in…
Myv2012 sonic 1.8 turn the fan at 233 or 235 and get cool down to 215 is this normal or not
That sounds normal to me. Many GM vehicle have the low speed fan come on at 220 and high speed at 235-240. Its best to watch coolant temp and fan command with a scan tool to determine if the fan is turning on at the correct temp.
@@ThePracticalMechanic mr one more thing the knock sensor where is located and is easy to remove it ?i got a code p0325 so i want to replace it but i saw other videos from diferen models and some of them u have to remove plany parts .thanks in advance
Armando Sanchez they are typically below the intake manifold. Some models require intake removal.
@@ThePracticalMechanic oh ok thanks
When should I replace it. Just hit 70000 mile
Well you could replace it now before it fails or wait until it starts leaking and then replace it. There really isn’t a set time point for replacement, most replace it after the check engine light comes on with a P0128 thermostat code or when they get a coolant leak.
I didnt get any code for mine. Mine just started leaking without throwing a code
Hey can I get the code too for the thermostat
L Edward the code I had was a p0597 but a p0128 is also possible.
@@ThePracticalMechanic thank you I found it
@@ThePracticalMechanic can I get the name an size of tools u used to take off the thermostat

That same damn hose with the clip broke on mine.
Do you have to attach the sensors back where they were originally were. Dose it mater
Yes you should attach the wires back to the same locations they were removed from. The sensors are checking different things and the computer might get confused if they are swapped.
And how easy would you it is to change the themorstat housing for a beginner
Stevenson Ceus It’s not a super hard task as long as you take your time you should be able to do it. Although it seems like a quick and easy process in the video it may take you much longer to perform the replacement. I think the worst part might be removing all the clamps and unbolting the lower metal pipe from the housing. You may want to watch the video a few times and make sure you have the correct tools and feel comfortable with the job.
Ok thank you man. You’ve given me the confidence to do it.
heater in mine wasnt very good, so i changed the thermostat/housing its good now, on the old one the o ring around the thermostat was coming out which lets coolant by, just like if it was the thermostat not closing all the way. if changing just the part i did you only have to remove the radiator hose, then unbolt the oil cooler pipe and loosen/back off the bolts to the plastic housing thats against the head to make room to remove the thermostat. also with that code you only have to change that thermostat housing as the heating element right by the thermostat is the cause.
Can u replace the thermostat only without the housing? I havent gotten a code but it's leaking from thermostat. I'm constantly adding coolant.
If it’s leaking the housing Is probably bad. The coolant is corrosive and breaks down the plastic.
I had to remove the throttle body heater inlet two now it’s running rough when I try burping the system.
It's very common for the large air inlet hose to crack and fall apart between the throttle body and the air filter housing. I would check that and also make sure all the sensors are plugged in properly.
That hose from tstat to throttle body is a pain. You make it look so easy ,I'm stuck like 20 min. Either it plugs in one side and not the other,as if it's not long enough. It's right part# str8 from chevy.its just a pain.
I’m not real impressed with the design. It seems like you have to route the hose just right to have enough slack to install it. Did you get it to fit yet?
I put it down. Will try again.. crazy, I've done from brakes to plugs timing belt etc,etc but this little hose seem harder than the timing on this car. 😐😐 lol
Jose Deleon Sometime walking away for a day will fix the issue. I do that from time to time although I can’t walk away for too long unless it’s my own personal vehicle. Good luck tomorrow.
@@ThePracticalMechanic I put it down cause I work over nights and tried after work. Had to run and get part from dealer 30 min away woke up and had to go to daughter's event in school. I'll get it. Thanks
Yes your right also as previously mentioned on a comment routining the hose is a bitch
Hello, tkanks for the video that help me a lot, when I get off the air intake hose in the thermostat I broke it, my carr is a Chevy Sonic 2012 1.8 LT and my question is if it the same part Numbers AC Delco 25192905.
Appreciate...
according to the parts catalog it fits a 2012. the thermostat fit many models from 2010-2016 and the hose does as well.
Could you do a video on how to flush the cooling system regarding this vehicle?
Paul Wilson if I get the chance I will record it. I don’t personally have one of the vehicles so I will have to wait until one comes in the shop that needs a coolant flush or I can show the procedure on the next thermostat I do. 👍🏻
Wow Im never letting the mechanics from
The dealership I got my car from touch my car ever again. They didn’t do any of the flushing.
Did this without removing the housing
We typically replace the housing to prevent future leaks. This housing are common leak points on this engine.
@ThePracticalMechanic makes sense as long as you're willing to do the repair for less without replacing the housing. As long as you explain this to your customer they may choose to save money in the sort term. If you suggest the housing replacement to save on future labor and they agree then I don't see an issue with it.
Cooling issues galore
Chevy Sonic. The square radiator fan has a green resistor in it that has two fan speeds. High speed and low speed. You can not buy that resistor separately. The fan tests good, but the high speed resistor goes out and you only have low speed and your engine will still overheat and your A/C will not blow cold. You need to buy a new fan for $65 on ebay and it does go bad every 100,000 miles or so, because the turboed 4 cyl. engine creates so much heat and causes stuff to fail. That bad resistor fan might blow your 40 Anp fuse in your fuse box. Your fuse box in the engine compartment has two 40 Amp fuses. One fuse supplies power to the radiator fan and the other 40 Amp fuse supplies power to your blower motor in the cab of the car. The engine coolant temp sensor can also go bad from all the heat in the engine compartment. The sensor is actually part of your electronically controlled thermostat housing, so the thermostat, thermostat housing and engine coolant sensor come as one piece when you buy them on ebay. So what it comes down to is you should check 4 things if your engine is overheating(high and low speed resistor that comes with the new radiator fan, the thermostat, the coolant temp sensor that is mounted on the thermostat housing, and the 40 Amp fuse for the radiator fan that is in the fuse box in the engine compartment).
Cars should not be this much for trouble to repair. Come on America! You can do better! Start using your brains and stand up to politicians and corporations trying to make your life harder! This is just going to keep getting worse and worse because people just let them get away with it.
What a mess of a job
Lol what isn’t on these cars. I’m very careful while working on them now because everything is so fragile. One bump and something breaks.
For a THERMOSTAT!!!
That pipe is a bitch to fix
Lol It seems like they are making these things harder and harder to work on.
@@ThePracticalMechanic usually that hose/tubing the inside breaks off in tstat housing and you have to change everything
Exactly what happened to me. Now I just order everything right from the start because I know it will all need replaced.
This car is just trash
🤣🤣 couldn’t agree more. We should force GM CEOs and engineers to drive 5/10/15yr old vehicles they produce and decide what they can do better. These cars rarely make it past the 10 yr mark. All of my Toyotas have 200,000+ and I have three with over 300k. We did valve cover gaskets on a Toyota 4Runner last week with 550,000 miles and was still running strong.
Great job but Chevy Sonic is by far THE SHITTIES cares GM have ever built. SHAME!
wtf? You doing this all with the battery connected? what is wrong with you man?
I personally don’t disconnect the battery on any vehicle unless I absolutely have to. Many vehicle require radio codes, XM subscription information, onstar setting, radio settings, power window and sunroof initialization. Many other vehicle have intermittent module failure upon battery reconnection (mainly Dodge vehicle). I just use caution when working near the battery. Many may choose to unhook the battery when performing repairs like this. Thanks for checking out the video. 👍🏻
Also you made no note or comment on inlet vs outlet heater hoses.
They’re identical size and length, super easy to get swapped by mistake, like my sloppy mechanic did, causing problems....pretty sloppy:(
The thermostat is on the other side by the water pump. Your playing with the climate controls that allows coolant to flow to heater core in the cab.
