C7 Corvette over heating at random, need help.
so the past month or so the car has over heated 3 times at random timeswhile at idle or stopped,
it only does it when the car is idling for 5-10 min i cant rememeber if it was with the a/c on or off,
brought it to the dealership autonation chevy in orlando, and of course they find nothing wrong with it, no engine codes no nothing,
showed them pics of it over heating also ,
i cant reproduce it at while, it will be fine for weeks and then just happen at the wors time,
my best guess is a stuck thermostat or bad cooling fan of course chevy won’t do anything unless they actually see it over heating,
any idea how to get this fixed, besides letting over heat and blowing the engine to prove it has a problem ?
thanks

Overheating
One of the easiest and least expensive items to try is replacing the coolant overflow cap. Sometimes the O-ring pressure seal is worn and causes overheating. This has been an issue that has been solved on Chevy SSRs. Normally I don't like throwing parts at a problem without detailed diagnosis but the cap is cheap.

Keith is the best tech in Orlando for Vettes. I am kind of surprised he did not keep it and try to make it happen.
I did not see in your post what the temp gauges said the engine was running at? Was it above 190? When you popped the hood, was the fan running?

Keep the over flow cap off overnight and the air will escape, check the drivers side lower rad area and see if it's wet, there has been bad rads out there, mine was doing the same thing and sucking in air and over heating due to being air bound.

Just so you know, if you are not getting satisfaction there because you did not get Keith, other forum members had good service experiences at Stingray Chevrolet near Lakeland, and John Hall Chevrolet near Daytona. Call them and make sure you schedule and get a loaner. Call GM customer service and they may flat bed it if you think it might overheat on the way.
As the others have said, perhaps all it needs a simple burp? It only takes a couple of engine cycles to get the air out after I installed a Dewitt's radiator. It is so easy to over heat these cars in the horrific traffic, I4 deconstruction and killer stop lights with the Florida Inferno here in O-town.
