1 of the o ring was leaking, instead of buying the o ring, I found out that the coolers in the Spectra radiator have 1/4 npt thread, so I bought a 3/8 barb to 1/4 npt fitting, 3/8 transmission cooler hose and no more trans/oil cooler o rings for me.

I need to double check but it might not work with Nissen radiator.
