Has anyone heard of the 1.6 L Aveo engines (2006) going bad around 100,000 miles?

Good to hear they have been going the distance. I would imagine the metal thermostat housing is an aftermarket part. Who makes it and where did you get it?

The metal thermostat housing was used on the 2007 and up 1st gen Aveos.

I agree that many people drive things until it does not start or move. My son had told me about the 100K thing and his ex-girlfriend had a 2005 Aveo LS sedan 5spd that she had for her first car. She wanted to buy mine but told I did not want to sell it. I helped her find the 2005 and had her change the timing belt shortly after she bought it. It has about 100K on it now and did see it on the local Chevy dealer's lot for sale after she traded it in for a new Cruze with a turbo. I drove a Cruze and they are nice but her Aveo was paid for and in very nice shape. I guess she must have believed that rumor. She has years of payments ahead of her now. I will keep my Aveo.

I imagine that the metal thermostat housing will also fit the older Aveos then or was there a design change?

I am guessing you do not like Mobil 1 then? I have used it in many cars/trucks and have great luck with it. I use the 0W30 Fuel Efficency formula in my Aveo and it starts a lot quicker in winter and has stopped cold engine noise I use to get (valvetrain). The oil looks almost as good coming out after 7,500 miles as it does going in. In the land of oil you can have as many views on it as people on politics.

Yeah, the metal thermostat bolts right up.

Let mine go too long. The 5 cent plastic tentioner pulley failed at 76K. Caused $1600 in repairs. (Bent valves, widened valve guides, etc...) If you're over the recommended 60K, do yourself a favor and replace everything under the timing cover. Is the new 1.4 liter a non-interference engine?

Cool, I will have to change that when I do my next coolant flush.
