Ok, need some help on this one. Currently rocking a 2011 Chevy Cruze 6spd, new engine and replaced turbo, got it off a guy at work. Issue is, it likes to overheat when idling when the air is on. Not just A/C, but any air. As soon as I take off, everything goes down and it's fine??? It'll overheat all the way past the first warning and to the second, but all the levels look normal and as soon as I drive for a couple seconds everything is fine.
