I am looking to find out the I.D. of the H2 upper radiator hose, i am going to be installing dual electric fans, and i never cared for those probes, that get pushed though the radiator, i am going to install a joint/coupling that will accept a 3/8 npt temp sensor..i enclosed a picture of joint/coupling. ..

I know i could easily pull the hose and check, but i am just trying to avoid a mess...
