They replace the gasket between the tb & the upper intake along with the fasteners that connect the tb to the upper intake, then they add sealing pellets to the coolant.
I had this done well over a year ago under recall, I forget the number though. I had a small coolant leak at the under side of the tb where it makes up to the upper intake.
