simple question as i have looked here and elsewhere. does anyone know the size of the o-rings where the transmission lines attach to the radiator fittings. diameter is easy enough to figure out, but o-rings have width which varies by application. thank you.

 

I had the same issue when I replaced my radiator. I just took the old o ring down to my local NAPA auto parts store and they had a good selection of o rings which you can match individually. A good hardware store should also have a good selection. I don't think the radiator o rings are anything special such as would be the case with a AC system.

 

thanks, that is what i ultimately did. the one important thing is that they are of the oil resistant type.
