This car is overall pretty dependable. I drive it to and from work everyday, regularly change the oil and haven't had any major issues up until now. Last night, was driving and heard a pop. I looked under the hood and it had sprayed coolant all over, starting from the passenger side near the air filter box. Turns out that a lot of Aveo owners have had the same issue. The factory thermostat housing is made of plastic and is held together with glue. Mine basically separated into two pieces right at the gasket. Options are buy an aluminum one for approx. $100.. ($91.78 plus tax from the dealer) or use plastic weld to glue it back together. By the way...parts are only carried by the dealer.
Replace thermostat housing with aluminum instead of factory plastic
