hello all,
Just wanted to let fellow Aveo owners know this tidbit. I purchase my 2008 Aveo in September 2013 from day one I had to add coolant. Well fast forward to May 2016 on way home from work car overheated limped it home only to discover all coolant was gone. After inspecting it found the coolant bottle had sprung a leak. Mad dash to find part and upon removing old bottle notice it was full of small spiderweb of cracks since newer one went in no coolant loss at all. So if you are losing coolant check the bottle it may have a small cracks that seeps.
