How to Replace Thermostat Housing 12-18 Chevrolet Sonic (& Cruze 1.8L)

[@rockynelsonart3071]

did this before watching video and learned the hose clamps were soooo hard to work with. I found out that a a small vise script works great but it can be tough to get in the very back hose. just mentioning in case someone cant find that tool. thanks for the good vid!

These people ran some nasty stuff in their cooling system. Run only DexCool premix in mine, 2012, and everything is super clean inside and at the connections; it lubricates everything, and water pump is original! Never use tap water to dilute, always distilled to mix your own coolant. Replaced all the hoses last spring because they were swelling and collapsing with the thermal pressure changes. Black specks in the reservoir also indicates internal disintegration. If one is bad, change all five and two o-rings, 5/16 on the throttle body tubes. One atop the thermostat housing, the other at throttle body. I'm here to change a bit leaky thermostat housing, and the thermostat is fine and original so due.

[@alexanderhennes3712]

You mentioned you can buy replacements for the quick connect/disconnect coupling for the top hose connecting to the thermostat housing. Where can I find one? I have been looking and cannot find them or a suitable replacement.

[@benjaminwatson2695]

any luck? Just attempted this repair and that sucker broke about as soon as I touched it...

[@benjaminwatson2695]

unfortunately mine leaks from it now, even just when I was squeezing the radiator hose to burp the system....

[@localspookyboy]

It’s a throttle body heater inlet hose. Idk why the dumb thing is made of plastic if it breaks so easily

[@Shaq-ww3cy]

Just broke that connector that sits on top of the thermostat you was talking about. What is the name of it?

[@rdmineer1]

That line warms the throttle body. New line $20 has it attached new. See my main comment.

[@bturner2030]

Don’t be lazy and RTV every thing. Get appropriate gaskets! Do the job right

[@grantdubridge7995]

It looks like it comes with the appropriate rubber o-rings on the new piece.

[@denniswetzler2024]

dealer wanted $480 to replace thermotat. i bought it on ebay for $40 and watched your video and did it myself in 2hrs. #savethatmoney

[@candicedean5273]

could you help me out??? was it hard?

[@rdmineer1]

Vice grips can also handle the clamps, and other jobs as well. Original clamps don't fail unless rusted. Screw clamp is more expensive and seals unevenly. Proper tools, parts and fluids, people.

[@Mike-vk2ni]

Do not rtv that top hose how cheap that hose is replace that hose crazy to see someone jerryrigging a customers car

[@wurmzzlife]

What is that plastic piece called around 4:15? The one that is the connector that tends to break? I want to go ahead and buy that part b4 I start messing w my housing unit again. Thank youu!

Nice work and great explanation of what to look out for! Also loved the BNSF train horn as it came through town- figured San Antonio not far away!

[@josesierra198]

Thanks for uploading the video to show me exactly what not to do and buy all the correct parts what a hack

[@heatherdewater]

You didn't share name of tools needed or sizes as you said you would on video

[@liliangel101]

How much RTV did you use to stop the leak at the top port for the throttle body heater inlet pipe? I have a small leak there and was wondering how much you used?

[@jarrelljohnson7345]

Having the same issues, what did you do?

[@lt1swapgonzalezperez102]

Buy a new hose shouldn't be to expensive trust me it's better then rtv

[@localspookyboy]

Omg thank you finally I can put a name to this part. Mine broke off my thermostat yesterday and I had to tow it back to my cousins. He found the part but I’m definitely going to buy an extra since it gave me so much trouble.

[@rdmineer1]

Get the o-ring, 5/16, 4/$10. RTV is guessing.

[@samjam287]

Will this work for 1.4L 2016 chevy sonic?

[@sxero124]

No, the setup for the 1.4t is different. The thermostat assembly is on the passenger side of the engine, the water outlet housing is on the driver side of the engine. As far as I know there is no thermostat housing as shown in this video.. The thermostat for the 1.4t comes as an assembled unit (thermostat and housing) and doesn't seem to be separable.

[@peggyl7565]

I have a Chevy Sonic and the upper hose kept blowing off. Engine overheating. Lost all coolant and steaming . Towed it to the Chevy dealer service department and they said it had a cracked water pump housing and that was the problem. My question is could the cracked housing with fluid leaking, cause pressure to build up enough to blow the hose off?

[@logan-io]

Probably

[@bobdelabourer1307]

It has a poka yoke design. It has a cutout area in the heater core metal pipe and the high temp plastic fitting has a bump inside (look carefully you will see it) that bump has to fit into the cutout. if you don't line it up it will not fit in properly and the locking ring won't lock it so it will blow out.

[@localspookyboy]

My cousin replaced my water pump and then suddenly the throttle body inlet quick release broke off my thermostat too. Lost all coolant in a matter of minutes and luckily my car threw me a code on the screen for my air conditioner before the check engine light came on. The guy that stopped for me said that if I would’ve kept driving I would’ve totaled my engine.

[@rdmineer1]

No. Some dealership mechanics are hacks. I don't trust any, DIY all of this. My water pump and thermostat are original, 12yo and working perfectly. Thermostat is likely failed closed. Secret: DexCool has special lubricant, only use that.

[@rdmineer1]

O-ring only. RTV does not replace an o-ring application. Plus can form clogs.

[@JHinsonMusic]

ok, so what is the name o-ring the thermostat housing didn't come with? I have the same problem.. I haven't done this job because I can't find the o-ring i need.

[@rdmineer1]

@@JHinsonMusic it's squarish and already in place.

Your video don't show up if ya type 2013 Chevy Sonic Thermostat. But sure as shyt. Get so tired ya type 1999 Chevy Sonic and here we are 😅 Wtf 😂❤️✌️

[@bobbyc1828]

Nothing like the older thermostats. Great video!

[@treycarter6736]

Is it possible to just replace the thermostat and not the entire assembly?

[@kylehudson9658]

Yeeeaaaah you can but you might as well just replace it all. Did mine the other night and the housing with all the hoses cracked where the thermostat mounts just from trying to tighten it enough to not leak

[@AcidxAnarchy]

So what happens if you do get a bunch of air in the system?

[@mainedaddy420]

So what's the best way to get the hose the connects to the coolant tank to the thermostat housing unit

[@ProMachinist]

Nicely done and perfectly narrated Fixbook. You couldn't ask for a better step by step video. Andy ~

[@gingerwallets8000]

10:48 can someone tell me what that part is because mine is broken, the part that slides in broke off in my old thermostat

[@srt8man09]

Yea so the metal tube that came out of the thermostat on mine for some reason and now I have to do way more work

[@SharnaiPitts]

Should've gotten a metal one I bet you've already changed it out again

[@rdmineer1]

Line from atop the reservoir to the throttle body is the passive air bleed. That other o-ring is at the other end.

[@jeffreytyer4041]

My thermostat has been replaced a year ago and is leaking from the bottom part of the housing that you said does not do anything for this car. Will I still need to replace the whole housing again because of that or can I just seal it up?

[@nbain66]

Wouldn't hurt to try a sealant, especially if you know the rest of the housing is fairly new.

[@ahrboo]

Thx man

[@pyrogames4924]

Dont put RTV in Voss fittings. Just buy the assembly and not just the hose.

[@lt1swapgonzalezperez102]

I'm with you no need for the rtv cause it's has gaskets

[@Mike-vk2ni]

Agree

[@jahhdenn1430]

On the side of that reservoir where does that little plastic piece lead the overflow of coolant? Mines seems to let the coolant just flow out of the reservoir and into the engine bay if it gets up to that point. Is that normal for the coolant to rise? And then leak out of that top piece on the reservoir? Just curious if I’m missing something here.

[@austinhayes1540]

Late reply, but most likely it could be your cap

[@tuckerclement8743]

The metal oil cooler pipe that 90s. I pulled it out but cant get it to go back on. When i screw it back on the other side of it slips off and the coolant leaks out. It looks to be not long enough anymore. Any help would be great

[@Raymond.Earl.Official]

Cover it in rtv and sell it.

@@ethangonzales3000 air in the cooling system. Had to back the rear wheels down into a ditch, jack the front up as high as a low profile jack would go, then run a spill proof funnel with coolant at 3k rpm’s for multiple minutes to get all the air out. Pain in the ass. Would never buy one of these cars again.
