Did you flush it with a garden hose?
Pull out the thermostat and flush it with a hose again.
Might be a cracked head/head gasket.

turn on the AC while its parked, make sure both fans are turning.
I assume you have good oil pressure.
How bad did the coolant look the first time you flushed?

He would already know if the fans are working if its overheating motor driven turns when you start motor,electric fan will be on if its overheating give the guy a little credit to know something if he has flushed it already?

Thats a cheap and easy check grab a new one and gasket and try a swap if you want to know for sure through it in a pan of hot water to see if it opens first then pull her out and watch it close.

A/C condenser clear/clean, not plugged with mud/bugs/trash? Verified overheating with a gauge other than the factory dash gauge? New t-stats have been known to be bad, rarely. Like rich said, test it.
FWIW, here's pics of a 180 t-stat closed and wide open at 195.
