http://www.ncttora.com/fsm/1993/engine/93throttle.pdf page EG2-239 (the procedure is uncharacteristically obtuse).

This might help to understand what the Air Valve does. http://www.ncttora.com/fsm/1993/engine/82operatio.pdf

It's located in/on, and/or is an integral component of, the throttle body . On the bottom side of it, roughly in between the 2 coolant lines that connect to it on each side.

More on coolant heated wax type air valves can be found on page 6 of the following .pdf
