I have a 2010 Chevy Aveo LT and have problems with the cooling system. I believe that it is the thermostat that is the cause but not totally sure. I just tore my engine apart and am having problems with finding a manual for this year model. Luckily I have a friend that has been helping in doing the above. I would like to know if there are other owners who have had this problem with earlier or same year vehicles.
