Mystery M20 Bolt/Coolant?

[Wardie]

So my engine guy gave me this bolt and said I was gonna need it. soooo yeah here it is and what is it?

It looks like it is the fitting for the throttle body coolant return line that threads into the block, at the #6 cylinder, under the intake manifold.

Number 28 in the diagram.
