Hello! Working on an engine swap in my 92 TPI car...been a while since we took everything apart. On the stock radiator there is a threaded female port on the passenger side just below the filler neck and above the upper trans cooler line. Appears to be 1/4" NPT. What goes there???

 

I think you are talking about the coolant level sensor port for GTAs

 

So not applicable for my application? Just plug off I guess.

 

Yeah, you should be able to just plug it if it doesn't already come with a plug
