Fan switch in radiator

[ozyvr4]

Hi there. Ijust bought an alloy radiator and was wanting to fit the standard fan switch. Does anyone know the thread type & size so i can get a weld in bung to fit. I wanted to set it up before I remove the old radiator so i can just swap them over.

Ha, I literally asked this less than a month ago! I found out the size on my own; I believe it's 16x1.5. do a search by my username to be sure.
