I just had my thermostat housing bust last week, I was able to get a new part from the dealership, the part cost $90 bucks and was made of metal. The metal part looks to be a lot more durable than the plastic that busted. Installation was a cinch and took under 30 minutes
 
Well, if nothing else, its good to see GM reacting positively to correct what may become a larger issue as the Aveo ages. A recall would be nicer, though...even though the plastic housings appear to survive the warranty period in most of the pre-extended warranty Aveos...

Today, we experienced this problem. My mother and I went to go play tennis at the courts which are about 2 miles from here. We smelled a burnt antifreeze type smell. NO indicator lights came on at all and the temperature gage was neutral. When we arrived at the courts, we lifted the hood, and out came smoke. It looked as if something had been spewing all inside the hood and over the engine and even the passenger side head light. The reservoir tank was empty. We filled up the tank with water, which is all we had, and played tennis. An hour later, we drove back home (approx. 2miles). As we reached the driveway, the temperature gage was heading up to hot. As we parked the car, it reached the red zone. We lifted the hood and smoke bellowed out. The same smell was there. A friend came over to check the car after it cooled for about 3 hours. We used the water hose and filled up the tank, and the water came pouring out, where the housing was split in two.
We are replacing tomorrow at home, but does anyone know if any other damage was done by driving it home?

Probably not because you arrived home as the temperature gauge went to red. Make sure you put the proper mix of water and antifreeze.

2004 Chevy Aveo Busted Thermostat by cclement1

Dear Fellow Aveo Owners - I can't tell you how glad I was to find this forum. The thermostat housing on my Aveo burst - also with no lights, steam or warnings- in fact, up until my car stopped running with a (possibly) frozen engine and a blown head gasket- it seemed to be running great. I had no warnings at all. The third party warranty people sent an adjustor to check out the engine and refused to cover any of the cost. I am battling with the dealership and the warranty company about this and was starting to think I was really negligent and it must have been my fault until I saw all the posts about this same problem. I have not received any service bulletins about this and would like to know more about where to find out about how to try to get some help with this. Of course, neither the dealership nor the warranty company have said anything about this. Any thoughts?

Well first it is a rather new issue here on the forum with only posts about the plastic housing coming in the last 6-months or so. It also appears that it takes a couple/few years for the housing to finally deteriate and crack.
 
I would printout the forums posts to use as evidense of this problem for one. I can't advise in further.

We are having the exact same issue with our 2005 Aveo. We bought the car new in 2005 and this is the 2nd problem we have had with the vehicle. We no longer have any warranty on the vehicle because we did not purchase the extended warranty. We have about 65,000 miles on the car because we used to live about 20 miles away from our jobs and commuted daily. In the middle of the week my husband was driving from his job to pick me up at my job and found that the car was over-heating! Of course there were no warnings, no lights, nothing to indicate a problem other than the the thermostat rising. We checked out the engine, added antifreeze and it came pouring right back out like a water hose!!! We found that the thermostat housing had busted. Upon calling the dealer, we were told there was no warranty to cover this issue. We called around to see if we could purchase the part from the local parts stores, and were told it's a dealer item only. We called the dealer to get pricing and we were told that the part would cost about $25 and were relieved...until they tried to look up shipping info, then the price trippled to $90 and they told us that the part had to be updated because the part they quoted the first time (the "old part" as they called it) had to be updated because it didn't function properly. So, the "old part" is what the manufacturer put in our car when building it. SOUNDS LIKE A RE-CALL ISSUE TO ME! WHAT DO YOU THINK? SHOULDN'T THIS PART HAVE BEEN RE-CALLED?

can you believe that this happen to me too today out of all days. i was on the freeway and it was raining. I'm trying to find out if its going to be covered by the warranty because my car only has 33,000 miles on it. But by the looks of this from other people that it has happen to I don't that it will, but oh well. Also I"m trying to call local dealerships, but they have not returned my call. the worst part is that I live 40 miles away from home where this happen, Lucky this happen within 2 miles from my aunts house but i think you are right, this part should be recalled. I'm going to call chevy on monday.

But before I noticed what has happen I felt like a loud click (sound like when you shift gears) then by the smell of burning water. Since where was a lot of traffic on the freeway and it was raining, I tired to get off as soon as I could, until 5 blocks later I was able to pull into an exit ramp and into a parking lot, that's where I saw what has happen. Lucky there was a auto zone close by and they told me what part it was and that I had to get it from the dealer. But by the looks of this I don't know about the warranty from other people that it has happen to I don't that it will, but oh well.

I'm going to call Chevy on Monday. I also think these cars should be recalled

As I've read this, I also had gone to the internet searching on the issue. This is actually the first time I have seen a thermostat permanently enclosed like this. This is a know defect issue with Chevy; however, it is happening around the 30K - 46K mileage. Short reasoning for this: it's happening about the time most cars go out of warranty. This is not a "power train" part to them. Yes it can affect the power train, but it's not, so it gives them an out. The dealers and any mfgs are going to try and squirrel out of having to pay in any way possible.
 
This is not specifically an DOT issue either, but here is what I sent DOT, NTSB, BBB and my state Attorney General. I suppose you can even send something to the EPA... I'll have to look into that. It is happening more often than you might think, but nothing will get done if you don't speak up. Oh, be sure to keep any tow and parts receipts. Actually it will do best to scan them.
 
2005 Chevy Aveo.
Thermostat is originally, from factory, permanently encased in a PLASTIC type housing. This is all ONE (1) piece. Chevy has superseded this item with a METAL type housing within their ranks/computers, because it was a known issue. This item (Plastic Thermostat Housing) knowingly splits as early as 30,000 miles, for us it was about 46,000 miles. This was never a recall item nor was any information ever sent out warning about it.
 
Failure of this part leads to the known leaking and expelling of hazardous anti-freeze/coolant on roads but also leads to the unrealized overheating of engine. This can lead to unnecessary engine damage from simple overheating of oil to the extreme of blown head gaskets, blown/broken cylinder rings, warped engine heads or complete engine seizure.
 
Chevy retails the new Metal part from
$82.00 - $95.00. This failing part was known early enough that the new product had already been made and distributed to dealerships. Web logs are full of this particular failure, on this vehicle.
