#19 of 78 Same problem by smk0926 May 09, 2008 (4:59 am)
This just happened to me last night. I just want to make sure I am doing this right, so does anyone have any directions or advice when replacing the housing? Thanks...
#20 of 78 easy fix by moortin May 09, 2008 (5:58 am)
It was really simple, get the part at your dealership. It goes right back on easy, other that wrestling with the hoses.

Replying to: moortin (May 09, 2008 5:58 am) It was very easy to put on it only took me like two minutes, u can put the hoses on first, it makes it easier. But their cheap plastic part could have cost me alot more, what if it got to hot and blew the head gasket or warped or cracked the head or block. Im sure Chevy would tell me I overheated it and Its not covered under warranty. My wife was driving when it happened and Im surprised she didnt just try and drive all the way home the way it was. I know Its a cheap car and I know chevy didnt even build it but this part sems to be a weak point in the cooling system, it couldnt hold a whopping 16lbs of pressure. Im sure someone has brought htis to their attention. They should have known glueing the thermostat between two plastic parts wasnt gunna hold long. I dunno I guess Im still pissed and needed to vent.

I am trading mine in as soon as possible. I am thinking about a Chevy Cobalt- but am going to research these same issues before I make up my mind. I have to drive 100 miles plus a day and don't want to be driving around with the damage probably incurred when this part broke. It was stupid to think glue would hold this part together.

Replying to: tomh4 (May 09, 2008 9:12 am) It sounds like this is starting to become an issue as of recent. I am positive GM would cover your engine if something serious were to happen especially if its maintained and under warranty. There may be other manufactures who refuse warranty service but GM is not known as one of them.

Replying to: moortin (May 09, 2008 9:20 am) I have driven both cars and the Aveo is nice for what it is in the sub-compact class. The Cobalt is a step up in size overall and is a nicer ride especially for long distance commutes. The Ecotec engines are arguably best in class and get great mileage. The new model has been out since 2005 so the minor kinks have been worked out. It is on the top of my list along with the Saturn Astra.
#25 of 78 Perhaps Aftermarket? by luckins May 11, 2008 (10:16 am)
I am waiting to see if the aftermarket manufacturers might put out an option of a metal thermostat housing in the future. At lest, that's what I am hoping.

#27 of 78 Aveo thermostat issue/motor mounts by commuter8 Jul 06, 2008 (9:14 am)
The plastic thermostat on my 2005 Aveo also broke. I felt a slight vibration in the car, heard parts rattling in the engine and pulled over immediately to find fluid leaky from my car. No warning lights, no nothing until this happened. After taking it to the dealership it was determined that the cause of the thermostat breaking was due to the motor mounts shifting and causing the engine to drop (scary) and shift to the right. They fixed the mount, adjusted the engine to its normal position and then replaced the thermostat housing with a Metal one!

Replying to: commuter8 (Jul 06, 2008 9:14 am) 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. Replies to this message: busiris (Jul 07, 2008 4:07 pm)
