I replaced the thermostat on my Wife's 2010 Aveo5 LT. Easy job, hardest thing was getting to the radiator drain, till I was done! Got the new on in, hoses hooked up and coolant added. Started up, let it warm up then drive to get gas. I check under the hood before coming home, luckily I was only a mile from home, the housing it mounts to is cracked! I don't know what to do now. I took tomorrow off and am looking to get the housing and hopefully a water pump. No such thing as a simple job I guess.
